China Cracks 100 Gigawatts of Solar Capacity as Musk Pitches More U.S. Gigafactories

When it comes to solar energy, China is on one hell of a roll.

In the first half of 2017, the massive country added a record 24.4 gigawatts of solar electrical generating capacity. This boosted its total solar capacity to 101.82 gigawatts. By comparison, China has about 900 gigawatts of coal generating capacity, but recent coal curtailments provide an opportunity for renewable energy to take up a larger portion of China’s energy market share. Such an event would provide a crucial opening for the world to begin a necessary early draw-down of global carbon emissions in the face of rising risks from climate change.

(The government of China proudly touts its clean energy advances. Trump Administration — not so much.)

This very rapid solar growth rate, if it continues, puts China on track to beat its 2016 record annual solar installation rate of 34 GW. And, already, it is 9 percent ahead of last year’s more than doubling of new annual solar capacity toward a likely 2017 build-out at around 40 GW. China is also adding new high voltage power cables and averaging about 25 GW of new wind energy capacity each year. A stunning combined wind and solar build rate that has led CNN to claim that China is crushing the U.S. when it comes to renewable energy production and adoption rates. With the Trump Administration still wallowing in climate change denial, withdrawing from the Paris Climate Summit, and courting dangerous deals with petro-states like Russia, it’s enough to make you wonder if American technology and climate leadership are a thing of the past.

Back in the states, more progressive American (it’s not tough to beat Trump in this regard) Elon Musk was trying to help prevent just such a slide into backward-looking regression. Addressing 30 state governors at the summer governor’s association meeting, Musk explained that only a 100 by 100 mile square region was needed to capture enough solar energy to power the U.S. and that the battery storage needed for such a system to provide energy 24/7 would only cover a region 1×1 mile in size.

(Elon Musk claims an area of solar panels the size of the blue square could power the U.S. The black square represents the size of the area needed for energy storage to provide 24/7 power. Image source: Tesla.)

This is less than the total rooftop and highway area of all buildings and roads in the U.S. Musk also soft-pitched the notion of new gigafactories to the 30 state governors in attendance. Hopefully, a few will take up what amounts to an amazing economic opportunity. With Nevada seeing major new growth surrounding Musk’s Gigafactory 1 site, you’d think that interest would be high.

Oddly enough, 20 governors were AWOL at the meeting. Primarily republicans, apparently they had “more important” work to attend to than helping America become energy independent while fighting to prevent the fat tail of global climate catastrophe from crashing down on their constituents like a 1960s Godzilla on a mad romp in Tokyo.

Steve Hanley of Clean Technica notes:

“Whether any of the governors will take Elon’s words to heart remains to be seen. Only 30 of them bothered to attend. Many Republicans stayed home so they could focus on challenging issues like how to discriminate against Muslims, slash Medicare rolls, promote more fracking on public lands, and prevent transgender people from using public bathrooms. When you are in government, it is important to keep your priorities straight.”

Global Sea Ice Coverage Has Fallen Off a Cliff — Impacts Likely to Be Wide-Ranging

Frozen water.

It’s an important aspect of our world. One that is essential to maintaining a stable climate and, by extension, the health of modern civilizations. Today, due to a continued warming of the globe, every form of frozen water — be it frozen water locked in glaciers, snow, or sea ice — is under threat. And we are almost daily reminded of new losses coming from these needed collections of cold.

Recently, however, one of these subsets of global ice has taken a very serious blow. For this past year, as ocean and land surfaces warmed to above 1 C warmer than late 19th Century averages, has seen a precipitous fall in the coverage of global sea ice. And we are now in uncharted territory as the Earth’s sea ice extent, area, and volume have fallen to never before seen lows.

(Sea ice area [upper right], extent [upper left], and volume [lower graphs] have all seen very serious declines that have now lasted for a full year. Since reflective sea ice is an important regulator of global and regional climates, the impacts of such a considerable loss is likely to be both long-term and wide-ranging. Image source: Global Sea Ice.)

Total sea ice area and extent have now ranged between 2 and 3 million square kilometers below the 38 year average for about a year now. That’s a region of sea ice larger than Greenland which has been removed from the face of the Earth now for the better part of four seasons. Global sea ice volume losses are now in the range of 12,000 cubic kilometers — each cubic kilometer roughly equal to a moderate-sized mountain. These are very considerable losses. But perhaps more ominous than the losses themselves is the fact that they seem to be sticking around — locking in a permanent warming-related-change to the Earth System, its weather and environment.

To be clear, there are some things that sea ice loss does not directly impact. And the first of which is sea level rise. Because sea ice already floats on the surface of the ocean and because it already displaces water, melting sea ice does little to change the level of the ocean surface directly.

(A very informative video describing ice albedo feedback. We do not, however, support some of the video’s sponsors who, unfortunately, appear to be ubiquitous.)

That said, there are many things that sea ice loss does affect. And the first is global temperature balance. Sea ice serves as both a reflective shield that throws back the sun’s heat during summer and as an insulator that locks warmer ocean waters below during winter. Remove a significant portion of the global sea ice, as we have done, and you’ll end up with oceans that both draw in more heat during the warmer months and bleed out more stored ocean heat into the atmosphere during the winter.

Such heat will be both stored and delivered exactly where it can do the most harm — in the polar regions. And, as a result, recently ice-liberated oceans will warm more rapidly in areas that are directly adjacent or close to the very large glaciers covering Greenland and Antarctica. As such, though melting sea ice has no direct, immediate impact on sea level rise, it can create an added pressure for the loss of land-bound and sea-fronting glaciers that will raise ocean levels if they melt.

(Arctic sea ice loss feedbacks produce complex and far-reaching impacts to the entire Arctic system. Image source: National Science Foundation.)

Arctic regions also face considerable added heat pressure to permafrost, boreal forests, and other carbon stores as a result of Arctic Ocean albedo feedbacks due to sea ice loss. In addition, warm pools of ocean water in the far north will aid in further destabilizing already-altered weather patterns. So sea ice loss is likely to continue to result in a worsening of the Jet Stream excursions that have already contributed to extreme weather — particularly in the Northern Hemisphere.

But perhaps the most concerning impact of sea ice loss is an alteration to seasonal temperature exchange. More heat absorbed by oceans during summer and then ventilated back to the atmosphere during fall and winter will tend to result in a lag in global cooling into the fall season even as winter will tend to warm.

(A roll-back of sea ice results in much warmer temperatures over nearby permafrost zones. This week, 81.5 F [27.5 C] temperatures are predicted for parts of the Yamal Peninsula — a region that has recently drawn attention for its newly discovered methane blow-holes. Image source: Earth Nullschool.)

Such a lag enhanced by sea ice loss is arguably already in play in the Northern Hemisphere — where increasing rates of heat exchange between the tropics and middle latitudes and the pole have already been observed. However, if Southern Hemisphere sea ice remains reduced, a similar heat exchange and polar amplification pattern is likely to begin setting up there as well.

The upshot is that the observed considerable loss of global sea ice coverage is likely to produce harmful or disruptive feedbacks in the Earth’s climate system in the near term. Stresses to the other frozen systems of the world will tend to increase as a result. Extreme weather events are at risk of worsening. Rates of polar warming could escalate. And disruptions to traditional seasonality will tend to become more apparent.

June of 2017 Was Third Hottest on Record for Globe

According to NOAA, June of 2017 was the third hottest such month in the global climate record since temperature tracking began in 1880. For NASA, June was also the third hottest on record with June of 2016 settling in at 1st hottest, and 2015 and 1998 tied as second hottest. Overall, global temperatures were about 0.91 degrees Celsius warmer than late 19th Century averages in the NASA record and about 1.02 degrees Celsius warmer than the same time period in the NOAA record.

(NASA’s land-ocean temperature graphic showed most of the world blanketed in much warmer than normal conditions. Image source: NASA.)

Around the globe, various climate extremes were quite visible as a result of such considerable warmth. Arctic sea ice extent was 6th lowest on record according to NSIDC while Arctic sea ice volume was the lowest ever recorded according to PIOMAS. NSIDC also found that Antarctic sea ice extent was the second lowest on record. Combined, global sea ice area was the lowest ever recorded.

Weather disasters included severe hydrological events likely influenced by increasing atmospheric water vapor content and evaporation rates due to climate change. These comprised Bangladesh’s devastating June floods and a still ongoing African drought spurring worsening hunger and increasing instances of mass migration. Meanwhile, seven maximum temperature records were broken with the highest temperature ever recorded in Asia during June occurring at Ahwaz in Iran on June 29 and an all-time national June heat record set in the United Arab Emirates on June 16th. Notably, no new all-time cold temperature records were set across the globe during June.

If present trends continue, 2017 is now on track to be the second hottest year in the global climate record. This despite a noted lack of El Nino in the Pacific following a very weak La Nina during late 2016 and running into early 2017. Though not as warm as 2016, it appears that 2017 will range about 1.1 C above late 19th Century values in the NASA record (according to analysis by Gavin Schmidt) along the current path.

This is a very warm range that is likely to keep pushing the climate system into gradually more extreme conditions. Atmospheric CO2, which is rapidly rising due to rampant fossil fuel burning, is likely to average around 407 ppm in 2017. As a result, global atmospheric heat forcing is on the rise with the trend likely to continue upward pending a major reduction in greenhouse gas emissions. Meteorologists, climate scientists, risk experts and climate journalists should therefore remain on heightened alert for dangerous trends related to global climate change.

Vermont Utilities Answer to Climate Change — Profit From Discounting Electrical Vehicles

“Green Mountain Power, the largest utility in Vermont, is promoting another aggressive clean energy offer to its customers — a $10,000 rebate on the purchase of a new 2017 Nissan LEAF.” Clean Technica.

“Burlington Electric is committed to building a sustainable energy future that reduces carbon emissions and supports a growing economy and a thriving community. Our EV incentive program is an important component of our efforts to drive our strategic net zero vision in the transportation sector.” Burlington Electric General Manager.


As citizens concerned about climate change, we often focus on the negative impacts of industry — which in the case of fossil fuels are presently many, varied, and growing. But we should be clear that a beneficial path forward exists for numerous clean energy industries in their ability to promote positive change through sustainability-focused technological innovation and expanding renewable energy access.

(In Vermont, tailpipe emissions account for about 50 percent of all harmful emissions in the state. Meanwhile, Vermont’s electricity grid is one of the cleanest in the nation. As a result, both utilities and government are providing incentives for increased electrical vehicle adoption as a means of shifting to cleaner renewable based electricity production and non-tailpipe-emitting electrical vehicles. Worth noting that EVs have no tailpipe emissions period — not just in Vermont. Image source: Drive Electric Vermont.)

This summer, Green Mountain Power announced its promotion of Nissan’s $10,000 dollar rebate program for Burlington-sold Nissan Leaf electrical vehicles (EVs) through September. Meanwhile, Burlington Electric, a municipal utility, is promoting similar incentives for new electrical vehicle purchases. To date, these are some of the most significant rebates for an electrical vehicle promoted by utilities and automakers — even eclipsing the Federal Government’s $7,500 tax incentive for EV purchases. Such aggressive rebates provide some clues as to where the utility industry may be headed in the near term as the number of electrical vehicles available on market continues to grow, as utilities take the opportunity to expand their demand base, and as various states ramp up their drives for cleaner air and net-zero emissions.

Clean Energy Transition Following in the Footsteps of the Information Age

Though not an exact allegory, we can find a number of corollaries between the presently emerging clean energy revolution, and the information revolution that has been ongoing for multiple decades now. Historically, those promoting the advancing information age did so, not just out of a desire to make money, but from a liberating drive to connect far-flung people and information sources. A process that many hoped would fuel the expansion of access to knowledge, speed innovation, spread democracy, socially leverage the power of thinking machines by creating equal access, and promote problem-solving on a mass scale.

(Green Mountain Power and other utilities are offering incentives for electrical vehicle purchases. Such incentives represent a decent opportunity for these companies to grow while also promoting responses to climate change. Image source: Nissan.)

This wave of technological innovation spreading information and growing social networking systems often relied on incentives for mass adoption which involved free or greatly reduced cost to access. This model drove waves of customers to new websites and services — taking a long view in which monetization and profit-making often occurred after a large number of subscribers was achieved. Google, Facebook, Twitter, Yahoo and many other platforms and services used this model to great effect.

And while the information age probably produced at least as many new problems as it solved, it appears far more likely that a transition to a renewable energy based society will generate far flung and much broader overall benefits. Energy independence, increasingly clean air and water, improved pulmonary health, and net zero carbon emissions are all in the offing. For in the age of rapid energy transition, mass manufacturing processes are enabling rapidly falling prices for clean energy, electrical vehicles and related energy storage systems. An event that has created a paradigm-shift-type opportunity for utility-based renewable energy innovators like Vermont’s Green Mountain Power.

Utility-Driven Electrical Vehicle Incentives

This summer, Green Mountain Power, which supplies 71 percent of Vermont’s electricity primarily from renewable and non-carbon based energy sources, announced that it would promote a $10,000 Nissan rebate off the purchase price of a Nissan Leaf EVs to its Burlington customers. Burlington Electric is providing a similar promotion with added incentives. The base price of a Leaf is about $30,000. Add in the rebate, an additional $1,200 incentive from Burlington Electric, and a $7,500 tax credit from the U.S. government and a number of Vermonters will be able to purchase the 107 mile range EV (soon to be 200 + mile range) for around $11,000 dollars.

(At 7 percent of electricity from solar, 15 percent from wind, and a significant amount of hydro-electric generation access, Vermont has one of the highest penetration rates for renewable energy. Adding EVs to the grid is an excellent way to further reduce Vermont’s overall carbon emissions. Image source: US Wind Energy Association.)

Why does this make good business sense for utilities like Green Mountain Power and Burlington Electric? Because for each customer that purchases a Leaf, utilities like Green Mountain and Burlington are locking in a considerable amount of increased electrical power demand while also spurring a larger shift that is beneficial to its business. The present Nissan Leaf has a 30 kWh battery pack that might average about 5-15 kWh per day of recharge electricity — increasing home and EV charging station consumption for Green Mountain power customers by 15-50 percent. And more often than not, owners of all-electric vehicles that do not require inconvenient gas station refills, annoying oil changes and who considerably reduce overall travel carbon emissions when connected to Green Mountain Power and Burlington Electric’s renewable grid will tend to remain EV owners — resulting in a considerable increase in electricity demand.

The push by Burlington Electric and Green Mountain has also been promoted by local clean power coordinators:

“Mobile sources, primarily motor vehicles, are the largest cause of air pollutants in Vermont, making up 46 percent of the state’s greenhouse gas emissions,” said Abby Bleything, Vermont Clean Cities Coordinator. “Burlington Electric’s partnership with Freedom Nissan, allowing customers to purchase a Leaf at $10,000 below MSRP, will help increase the number of zero-emission vehicles on the road, thereby taking a critical step towards reducing our state’s air pollution and dependence on petroleum.”

Green Mountain Power and Burlington Electric aren’t the only utilities to offer and promote incentives for electrical vehicle adoption. Southern California Edison, which serves 14 million customers, offers a $450 dollar clean fuel rebate. Meanwhile, Pacific Gas and Electric, serving 5.2 million, also provides a $500 rebate for EV purchases. But this is small change compared to the $10,000 rebates offered for Nissan Leaf EVs in Kansas last year and in Hawaii this year. Burlington Electric began offering a $1,200 EV rebate in May of 2017. It has since upped the ante by promoting a limited $10,000 Burlington Leaf incentive. With utilities, communities, and governments all looking to benefit from EV purchases, it appears that this emerging trend for power company based incentives and promotions has just gotten started.

Echoes of Fort McMurray — Massive Wildfire Forces the Emptying of Another Canadian City

A little more than a year after a massive wildfire forced the full evacuation of Fort McMurray in Alberta, another set of extreme wildfires in British Columbia is again forcing major population centers to empty. In the region of Williams Lake and Cariboo City, 17,400 people have been forced to flee as a wildfire is threatening the major highway exiting the area. As the fire expands, another 27,000 in the broader province may also be asked to leave. This mass evacuation has been enough to empty large urban centers — turning them into ghost towns as fires rage through the surrounding countryside.

On Saturday, 40 mph winds, hot temperatures in the 90s (F), and lightning strikes fanned flames in the region — considerably worsening the fire situation and spurring more comprehensive evacuation orders. Heavy rains earlier in the year caused rapid vegetation growth. But as much warmer than normal temperatures accompanied by dry, windy conditions entered the region in June and July, the new growth has turned into tinder — adding a serious fire hazard.

(Scores of very large wildfires rage across British Columbia on July 15 — casting smoke plumes that now stretch across most of Canada. For reference, bottom edge of this image frame covers roughly 550 miles. Image source: NASA Worldview.)

Presently, 160 wildfires are now burning across British Columbia. This number is down from more than 200 fires earlier in the week. However, many of the larger fires have grown in size. The result is that the province is still under a very severe alert level 4 with a mass mobilization of firefighting resources underway. On July 15, the fires were clearly visible in NASA satellite imagery (see above).

Precipitation extremes and increasingly warm temperatures are a hallmark signal of human caused climate change resulting from continued fossil fuel burning. And it is these kinds of conditions that have dominated British Columbia over recent months. Both the strong swing from wet to dry conditions accompanied by much warmer than normal summer temperatures is climate change related and has likely served to increase the fire danger throughout British Columbia this year.

Facing Down Climate Doom — Wallace-Wells’ Appropriate Alarm Earns Michael Mann’s Necessary Critiques

“Fear will NOT save us; however, fear is a prime motivator to promote new thinking and different action; to change an unsustainable status quo.” — unknown source.

“There are many things that motivate us. But the most powerful motivator of all is FEAR. “– Psychology Today.

“Both hope and fear are great motivators, and they both have the capacity to promote growth in us, but hope creates space in the mind and heart. Fear, more often than not, restricts it.” — Joyce McFadden.


When two parties seeking a good end passionately disagree over a crucial issue it is sometimes the case that one side is flat out right and the other side is dead wrong. But what is more often the case in an honest dialogue is that both sides are expressing a part of the truth and it is the duty of us, as observers, not to take sides, but to open our ears and learn as the necessary conflict unfolds.

Valid Warnings Against a Dark Future

This week, David Wallace Wells painted a scientifically imperfect, but truthful in broad-brush, picture of a bleak potential worst case scenario if human beings continue burning fossil fuels while dumping such massive volumes of carbon into the atmosphere.

Wells’ New York Magazine article was accurate in broad brush in that it depicted a possible worst case climate scenario where the atmosphere becomes choking and poisonous, heat becomes so great that it’s deadly to venture outside even in New York City, disease vectors multiply, breadbaskets are crushed by heat and extreme weather, and wars over dwindling resources escalate. In the larger scope, if missing the mark on a number of details, David Wallace Wells and NYMag get it right. If we don’t stop burning fossil fuels, this is basically what our future looks like. BAU fossil fuel burning ultimately looks so incredibly grim it is difficult to fathom or even talk about.

And this is the gift that Wallace-Wells has given us. The opportunity to talk about something hard and necessary. To learn and understand more both about the potential coming tragedy as well as the hope we now have in avoiding it. In other words, as science-based meta-analysis, speculation, and fiction often do — Wallace-Wells’ work helped to heighten a much-needed public discourse.

Adding the Scientific Process to the Discourse

Such a volcanic article eliciting such a powerful response was bound to draw some pretty strong critiques. And the article, in its more specific scientific failures, begged just such a reaction. Some of the best of these have come from Dr. Michael A Mann — one of the world’s best climate scientists and top advocates for rapid climate change mitigation.

Mann in today’s Washington Post notes:

The New York magazine article paints an overly bleak picture, arguing that climate change could render the Earth uninhabitable by the end of this century. Its opening story about the “flooding” of a seed vault in Norway leaves out that one of the vault’s creators told NPR “there was really no flood.” It exaggerates the near-term threat of climate “feedbacks” involving the release of frozen methane. It mischaracterizes one recent study as demonstrating that the globe is warming “more than twice as fast as scientists had thought,” when in fact the study in question simply showed that one dataset that had tended to show less warming than other datasets has now been brought in line with the others after some problems were corrected for. The warming of the globe is progressing as models predicted. And that is plenty bad enough.

And this criticism was absolutely necessary — pointing out some of the places where the New York magazine article had fallen down with regards to some of its factual basis. Wells mischaracterized the seed vault flood and a recent scientific study that basically matched satellite based temperature measures with land based temperature measures. Mann also claims that Wallace-Wells exaggerates the methane feedback issue — a very touchy subject in the present science and one that researchers have yet to convincingly nail down.

Massive methane burps are not inevitable. But they are certainly possible, and the risk grows the more the Earth warms. Loss of breathable oxygen to the extent that the article suggests is highly unlikely. But fossil fuel burning and anoxic oceans do reduce atmospheric oxygen on a smaller scale which is somewhat disturbing. And though deadly hydrogen sulfide burps from anoxic oceans are certainly possible under worst-case warming scenarios, the characterization of such events was probably a little overplayed to the minds of the more technically inclined. That said, Wallace Wells’ rolling clouds of death-inducing fog are entirely possible according to the scientific explorations of Dr. Peter Ward and Donald Canfield.

In other words, the article probably leans a bit more on the darker studies of paleoclimate as an allegory for potential future harm than is comfortable to the broader scientific community — which then led to assertions that his portrayal was closer to science fiction.  This despite the fact that some of the science does point to these kinds of worst case climate events that may look rather like what Wallace-Wells describes even if, as a technical matter, he’s somewhat off with regards to the present scientific consensus according to the well-informed opinion of Mann.

Wallace-Wells = Climate Change Denier is about Three Steps too Far

But aside from these much-needed critiques, Mann unintentionally does us a bit of a disservice here. By comparing Wallace-Wells with climate change deniers, Mann is creating a false equivalency argument. Moreover, Mann also generates false hope in the public sphere by appearing to down-play climate risks, even though that was clearly not his intention. In truth, Wallace-Wells falls far closer to the mark than any climate change denier. And if any of the consensus science that Mann relies on for his assertions happens to be wrong or too conservative, then a business as usual fossil fuel burning future could look a lot more like the one Wallace Wells describes than present scientific consensus expects.

In other words, Wallace Wells warnings may turn out to be more prophetic than an overly cautious science even if the various details of a climate disaster scenario play out in ways that few of us presently expect. The future is, in other words, murky. And you absolutely don’t want to be prodding the Cthulu that is climate change based mass extinction into full wakefullness by continuing to burn fossil fuels. Nor do you want to beg that potentially very bad future in giving ammo to climate change deniers by comparing a rather rational form of alarm with what amounts to an intentional deception that has been purposefully inflicted upon the public discourse.

Wallace-Wells and Mann Should be on the Same Team

All that unpleasantness aside, Mann’s most accurate and important statement follows a couple of paragraphs down:

It is important to communicate both the threat and the opportunity in the climate challenge. Those paying attention are worried, and should be, but there are also reasons for hope. The active engagement of many cities, states and corporations, and the commitments of virtually every nation (minus one) is a very hopeful sign.

And, ironically, I think it is here where Wallace-Wells and Mann probably agree. Unlike many of the Doomers that Mann rightly criticizes, Wells has recently spoken out as a staunch advocate for exactly the kind of clean energy and policy-based solutions that Mann so rightly and passionately stumps for. In other words, Mann was absolutely right to state that any fearsome climate message should also be tempered by the amazing hope and opportunity now available to us in the form of a renewable energy transition and a shift to less consumptive, more sustainable societies. And Wallace-Wells, while not shining a light on the various escape hatches available to us now in his article has appropriately used the platform given to him to talk about just these issues:

But, you know, there’s great news from green energy, there’s great news from renewables, the cost of wind and solar power is falling, not just dramatically but much more dramatically than even the biggest boosters would have predicted five or 10 years ago. A lot of that has to do with subsidies from the Obama administration and other similar, like-minded countries around the world. But there is really good news there. And there’ve also been some limited progress on what’s called “carbon capture,” which are devices to take carbon out of the atmosphere, which will almost certainly have to be one big part of the equation. With electric cars, etc. there’s a lot of tech innovation that should give people a lot of hope.

My hope is that readers will read the piece and feel motivated to think more about the choices they make, but also to this sort of consumption choices they make. And to agitate politically for policy options that will have a positive impact, and not think of climate change as a third or fourth order political priority, but as probably the most important issue we’re facing the world today, and one that should be at the top of our minds whenever we’re thinking about public policy at all.

Moving Forward with a Shared Vision of Avoiding Climate Catastrophe

In other words, Wallace-Wells is not our enemy here. He may have stepped on a number of his unqualified facts, but he’s gotten the overall message pretty much right. And if he’s gotten a bit carried away in being scared over bad climate outcomes, then he’s in good company ;). Moreover, he’s passionately advocating for exactly the kinds of climate solutions that are absolutely needed and that do provide us all with a good measure of hope — if we pursue them. In other words, Wells has talked about climate doom. But he doesn’t walk the path of doom itself.

Massive Wildfires Burn From California to the Arctic Ocean as Temperature Records Shatter

Record heavy precipitation and cooler conditions across Western North America earlier this year have again given way to record warmth as a strong high pressure ridge and associated extreme Pacific and Arctic Ocean surface temperatures have ushered in blazing heat and multiplying wildfires.

In California, massive wildfires have forced nearly 5,000 people to evacuate. In British Columbia, 14,000 have fled as more than 1,000 firefighters battle numerous large blazes. And along coastal Alaska and Canada’s Northwest Territory, large wildfires are burning near the shores of an, until recently frozen, Arctic Ocean.

(Large wildfires spill plumes of smoke over major sections of North America on July 11, 2017. Image source: NASA Worldview.)

In the U.S., the Whittier fire, which forced mandatory evacuations in southern California, is now 48 percent contained after having burned 12,000 acres. In the north of the state, near Oroville, the Alamo fire is 65 percent contained at 28,000 acres and evacuation orders have been lifted.

As large fires continue to burn across the west, the U.S. Interagency Fire Center now has a stated national preparedness level of 4 out of 5 — or the second highest alert rating. So far 2017 has seen 3,593,000 acres burned in the U.S. — which is above the 10 year average. An average that has already been pushed higher due to human-forced warming and an overall lengthening of the fire season.

Further north, British Columbia is suffering a rash of severe fires as extreme heat and high winds are blasting away at vegetation that vigorously regrew when drought conditions retreated earlier this year. Now, 215 active fires are reported as the province mobilizes national military forces and considers making calls for international aid. Presently, 21 large fires are causing considerable havoc throughout BC. Fire officials remain on heightened alert as strong winds, heat, and lightning threaten to make a bad fire situation even worse over the coming days.

Still further north and extending all the way to the shores of the Arctic Ocean, satellite photographs provided by NASA show large wildfires burning through typically frozen regions of Canada’s Northwest Territory and in northern Alaska. Many of these fires are quite vigorous — producing large smoke plumes that have blanked much of the region.

(Fires burning near the Arctic Ocean on July 10, 2017. For reference, bottom edge of frame is 280 miles. Image source: NASA Worldview.)

Such widespread burning over such a large region of North America — extending from California to the Arctic Ocean — has been spurred primarily by record heat building beneath a massive high pressure ridge. In the far North, temperatures approached 90 degrees Fahrenheit just south of the Mackenzie Delta near the Arctic Ocean earlier this week. Over typically cool British Columbia, temperatures have consistently ranged in the 80s and 90s and are expected to continue to hit near the 90 degree mark this week. And in the U.S. Southwest, numerous temperature records were broken over recent days as readings rocketed into the 100s and 110s.

Both the heat and these massive fires have likely been made worse by human caused climate change. Overall, global temperatures have recently hit around 1.2 C above 1880s averages. As a result, over 80 percent of the globe, heatwaves are both more severe and more likely to occur. Meanwhile, due to climate change related factors, the western wildfire season in the U.S. is now 105 days longer than it was in 1970 — just 47 years ago. Arctic sea ice retreat in recent years has likely accompanied further warming of the far northern land masses which have also seen increasingly severe wildfires over permafrost zones.

Antarctica’s 4th Largest Ice Shelf is About to Melt Back to its Smallest Area Ever Recorded

These days, there’s a big debate raging in the sciences over the issue of Antarctic melt. On the one side, you have a growing flood of data indicating that many ice shelves are thinning, that surface melt is more prevalent than previously thought, and that glaciers are threatening to destabilize at faster than previously expected rates. On the other side, we still have a number of hold-outs who rightly claim that ice shelves have always calved and that many of the processes we now observe have always been in place.

The scientific messengers sending these various indicators of Antarctic destabilization are cautious not to draw too many conclusions. But the data itself is pretty stark — which has been enough to produce some qualified, if very appropriate, warnings that Antarctica could be tipping toward instability far faster than previously imagined.

(The northern end of a massive rift in the Larsen C Ice Shelf is spawning numerous smaller ice bergs off a larger, Delaware-sized monstrosity. Now, only 3 miles of ice connect this emerging berg to the Larsen C ice mass. Once the berg separates, Larsen C will break back to its smallest area ever recorded. Image source: Project MIDAS.)

Of course the ice shelves named Larsen A and Larsen B existed throughout human times until they were only recently melted by warmth creeping up the along the Antarctic Peninsula in both the air and the water. Meanwhile, the Larsen C ice shelf is about to shatter off a very large 5,800 square kilometer ice berg even as several smaller ice bergs also appear ready to form. This event, which is now imminent in the coming days, weeks, or at most, months, will break the Larsen C ice shelf back to its smallest area ever recorded even as it marks a period of increased instability and risk of ice shelf loss.

For recent scientific assessments show that Larsen C is lowering in the water — an indication that the shelf is thinning. Furthermore, when the gigantic, Delaware-sized, ice berg and its smaller siblings break off they will take with them outer sections of a stabilizing compression arch. The compression arch, somewhat like the arch of a flying buttress, helps to balance structural stresses for the ice shelf. If it were to be compromised in total, according to glacier scientists like Dr. Eric Rignot, Larsen C would soon be adding its name to the list of various ice shelves around the world that have already fallen due to the warming airs and waters produced by human-caused climate change.

(The large ice berg that is presently breaking away from Larsen C appears to have bisected both southern and northern sections of the ice shelf’s stabilizing compression arch [indicated in the upper images by a solid gray line]. Loss of parts of the compression arch are an indication that Larsen C could become considerably less stable in the near future. However, some science indicates that the ice berg presently breaking off from Larsen C does not compromise key stability features. The nearer term future for the greatly reduced Larsen C Ice Shelf is therefore uncertain. Image source: Marine Ice Regulates Future Stability of Large Antarctic Ice Shelf.)

As with most predictive measures, however, the present trend isn’t perfectly clear with regards to the ultimate fate of Larsen C in the near future. Some studies have indicated that the section of ice breaking off is not crucial to the ice shelf’s stability. And the sections of the compression arch that are being taken out are closer to the outer edge of the ice shelf — not representing the key central arch region.

Overall, however, this story for Larsen C isn’t a good one. The shelf is thinning, it is about to reach its smallest area ever recorded, and even the loss of some outer sections of the compression arch are enough for a number scientists to express qualified concern. Larsen C didn’t show this level of instability back in the 90s or 2000s, so the overall trend here is more toward melt and instability for this 4th largest ice shelf in Antarctica.


As of 7/10/2017 through 7/12/2017, rift formation had finally met open water and the large ice berg breaking away from Larsen C had finally calved. From the Project MIDAS website:

A one trillion tonne iceberg – one of the biggest ever recorded – has calved away from the Larsen C Ice Shelf in Antarctica. The calving occurred sometime between Monday 10th July and Wednesday 12th July 2017, when a 5,800 square km section of Larsen C finally broke away. The iceberg, which is likely to be named A68, weighs more than a trillion tonnes.  Its volume is twice that of Lake Erie, one of the Great Lakes.

Racing to Catch Ludicrously Fast Model 3 Production Ramp, U.S. Automakers Grew EV Sales by 102 Percent in June 

Early on, Tesla recognized that responses to climate change were necessary — not just from individuals and governments, but also from industry. And Tesla realized that, when mated with wind and solar energy, electrical vehicles could become a powerful force for driving an energy transition capable of rapidly cutting global carbon emissions.

(Reduction in coal burning and lower than predicted demand for fossil fuels has helped to generate a carbon emissions plateau during 2014 to 2016. Rapid additions of renewable energy sources like wind, solar, and electrical vehicles provides a potential to begin to bend down the global emissions curve near term and reduce the damage that is now being locked in by fossil fuel based carbon emissions. Image source: IEA.)

Tesla’s Market-Driven Response to Climate Change

Electrical vehicles possess a number of key sustainability advantages that aren’t widely talked-about in the public discourse. Electrical motors are considerably more efficient than ICE engines — so broadening EV use lowers energy consumption in transportation while at the same time allowing EVs to draw power from traditional and newly emerging renewable sources. The massive batteries housed in EVs and sold after-market also have the capacity to become a major solar and wind energy storage asset that could ultimately enable the removal of peaking, high emissions, coal and gas plants.

In light of these opportunities, back in the mid 2000s, Tesla made a bold, necessary move. Its leadership decided that it would attempt to become a major automaker dedicated solely to electrical vehicle sales. This business plan would hitch Tesla’s economic future entirely to the success or failure of clean energy ventures. Unlike most present automakers, Tesla would not suffer from divided loyalties to harmful incentives linked directly to fossil fuel based economies. It decided to make its clean energy break by producing top of the market, high-quality electric-only vehicles and, then, by leveraging loyalty to a superior brand, move vertically down into broader market segments.

(If Tesla’s planned Model 3 production ramp to 5,000 vehicles per week by end of 2017 holds true, then the all-electric automaker’s quarterly deliveries are about to go exponential. Image source: EV Obsession.)

Such a disruptive end run on the world’s energy and vehicle markets was bound to encounter stiff resistance and loud detractors. However, if successful, Tesla would force traditional energy and transport players to make a tough choice — follow in Tesla’s footsteps and try to compete, or face dwindling customer bases as a massive wave of innovation completely upended markets. The automaker decided that the best way to goad a broader transition toward electrical vehicles in western markets was to lead it. And that’s exactly what Tesla has been doing.

Major EV Sales Growth on Tap for 2017 Due to Automaker Shift + Model 3 Sales

In the U.S., during 2017, the trend of an emerging industry reaction to Tesla is becoming quite clear. The major automakers are all in a scramble as the imminent arrival of the Model 3 nears. The vehicle, which begins production this month, aims to provide very high quality, Tesla’s trademark swift acceleration, top-notch tech, groundbreaking automation, and 215+ miles of all-electric range for a 35,000 dollar base price. An offering that is disruptive due to quality and accessibility alone. But add to it the 400,000 + preorders that Tesla has accumulated and you’ve got what basically amounts to a volcanic eruption in the global auto market.

In large part, as a response to Tesla’s market-transformation plan, a number of major automakers are deciding to provide their own competing offerings. This year, GM beat the Model 3 to the start line with the 200+ mile range, high-quality Chevy Bolt. Toyota, launched its competitively-priced Prius Prime plug-in hybrid. Nissan redoubled efforts to position its best-selling Leaf all electric vehicle even as it announced plans for a 200+ mile range version in 2018. Meanwhile, Volvo plans to electrify all its vehicles by 2019.

(Increasingly attractive EVs and plug in hybrids like the Chevy Bolt, the Prius Prime, and the Nissan Leaf helped to boost U.S. electrical vehicle sales in June as automakers gear up to compete with Tesla’s Model 3. Image source: InsideEVs.)

This activity has generated considerable growth in sales as customers discover electrical vehicles of ever-increasing variety, value and capability. During June of 2017, all-electric vehicle sales from major automakers in the U.S. market (excluding Tesla) increased by more than 100 percent over June of 2016 on the back of the entry of attractive, highly-capable models like the Bolt. Meanwhile, plug-in hybrid sales grew by 11.5 percent. Total U.S. EV and plug in hybrid sales for the month from major automakers + Tesla hit a new record in June of 17,182 on the back of major automaker sales growth (a total growth of about 16 percent for the entire U.S. market).

Tesla, on the other hand, showed slightly lower June 2017 sales vs June 2016 in U.S. markets as it experienced a hiccup in 100 kw battery pack production. But with the Model 3 nearing launch, an explosion of EV sales from Tesla is in the offing over the coming months. According to statements by Tesla CEO Elon Musk, the ground-breaking vehicle is expected to trickle into the market by adding about 30 sales in July. By August, deliveries are expected to triple to 100. By September, another 1,500 or so Model 3s are expected to arrive. Production will then, according to Musk, swiftly ramp up to 20,000 per month by December.

If these ambitions bear out, and if about half of Model 3 sales are in the U.S., then the U.S. could see north of 40,000 EVs and plug in hybrids sold in the U.S. during December. This would represent a 60 percent + jump over the all-time record EV sales month of December 2016. But even if Tesla’s extraordinarily ambitious production ramp-up goals for the Model 3 aren’t reached by December, the excitement surrounding the vehicle is likely to continue to spur growth and competition in the larger EV market through the period. And that’s a bit of much-appreciated good news for those of us who are increasingly concerned about climate change.

Scorching 129 Degree (F) Temps Hit Iran; Severe June European Heatwave Attributed to Climate Change; Satellite Data Confirms Rapid Global Warming

In a slew of climate change related news this week, Iran’s city of Ahvaz saw temperatures hit near the highest readings ever recorded on Earth, a new scientific model study has found that climate change made the recent heatwave that hit Europe this June two to ten times more likely, and climate change deniers lost a major cherry-picked talking point as the most recent satellite data now confirms the rapid global temperature rise that ground stations have been reporting all along.

129 F in Iran — Near Record for Globe, But Not a 35 C Wet Bulb Reading

On Thursday, in Ahvaz, Iran, temperatures hit a blazing 53.7 degrees Celsius or 128.66 degrees Fahrenheit. These temperatures were just shy of the 54 C (129.2 F) global records in Mitribah, Kuwait on July 21, 2016 and in California’s Death Valley on July 30, 2013 identified by Chris C Burt of Weather Underground. The reading was also the hottest temperature ever recorded in Asia.

This very severe high temperature came just one day after the thermometer struck 52.9 C (127.2 F) on Wednesday and is the strongest temperature spike of a broader Middle Eastern heatwave that has been baking the near-Persian-Gulf-region for many days. Such severe heat did not, however, tip wet bulb readings above the 35 C human self-cooling threshold despite an extremely hazardous heat index near 142 F. A combined dew point of 72 F, a 129 F temperature, and 995 hPa pressure resulted in wet bulb readings of around 30.2 C for the city — quite dangerous, but not beyond the human limit for temperature self-regulation.

June European Heatwave Attributed to Climate Change

As the Middle East was testing new all-time high temperature records for planet Earth, Europe was also sweltering under combined severe heat and drought. Throughout June, dry weather and high temperatures have plagued Europe. Extreme record heat sweltered the UK, France, Switzerland, the Netherlands, and Belgium — setting off heat emergencies and forcing some regions to ration water. Belgium as a country saw its highest night-time temperature readings on record. England endured its hottest day since 1976. Meanwhile, the heat and extreme dryness set off wildfires that resulted in the tragic loss of 64 lives in Portugal while 1,500 were forced to evacuate from similar extreme blazes in Spain.

(June heat set off a rash of extreme conditions across Europe. World Weather Attribution has linked this extreme event to climate change. Image source: Climate Central.)

This kind of heat is becoming more typical around the world as global temperatures have increased, on average by around 1.2 C since the 1880s. And a recent climate change model attribution study has confirmed that this particular heat wave was a lot worse than it otherwise would have been without the added kick provided by human-forced warming. For a study by World Weather Attribution found “clear and strong links between June’s record warmth and human-caused climate change.” 

According to the new study:

“These high temperatures are no longer rare in the current climate, occurring roughly every 10 to 30 years depending on the country. The team found that climate change made the intensity and frequency of such extreme heat at least twice as likely in Belgium, at least four times as likely in France, Switzerland, the Netherlands, and central England and at least 10 times as likely in Portugal and Spain.”

Satellite Data Confirms Rapid Global Warming

In another climate science related development, remote sensing researchers at the University of California have significantly revised their lower troposphere temperature record. The revision corrected for orbital decay in satellites that caused the world to appear to warm more slowly than actual trends. As a result of these revisions, a significant subset of the satellite data now largely confirms the more accurate land based temperature record showing significant global warming over the past few decades.

(Satellite data revised to correct for orbital decay now basically confirms land-based observations of global temperature increase. Image source: Carbon Brief. Data Scource: RSS and NASA.)

Dr Carl Mears, a co-author of the new findings, in a statement to Carbon Brief noted:

By correctly accounting for the changes in satellite measurement times, the new satellite data are in better agreement with the surface data.

Carbon Brief goes on to add that:

Unlike the satellite temperature record, where only a few satellites are measuring temperatures at any given point of time, there is a large amount of redundancy in surface temperature observations, with multiple independent sets of data producing consistent results. Therefore, it is not too surprising that corrections to problems with satellite data would move them closer to surface records.

Climate change deniers (self-labeled skeptics), have long pointed to satellite data showing the Earth warming at a slower rate than land-based measures. These ‘skeptics’ have then gone on to falsely claim that such data throws the whole issue of human-caused climate change into doubt. But this same group has failed to acknowledge the fact that orbital decay, as pointed out by the very researchers that run the satellite sensors, tends to result in artificially cool readings.

The recent reworking of satellite data to account for orbital decay along with researchers’ direct acknowledgement of the higher accuracy of land-based data removes the rational scientific basis for this line of ‘climate skeptic’ argumentation and renders past assertions in this vein mostly moot.

With India Building Solar Power Stations For 65 Cents per Watt, Suniva’s ITC Complaints Kinda Make You Want to Laugh (and Cry)

So in the world of solar there’s various different price structures. There’s cell prices, there’s module prices, and then there’s total system prices. The cells are the little bits that go into a solar panel. The module is the solar panel itself. And the system is the complete array of modules that’s been racked, packed, and assembled.

Solar Cells are Now Produced For as Little as 20 Cents Per Watt

In business, the best way to get the lowest prices is to do things en masse. The largest, most efficient solar assembly plants in China and Southeast Asia now produce solar cells for as little as 20 cents per watt. As of June 28th, solar modules from this region were going for as little as 33 cents per watt.

Low to very low solar cell and module prices are helping to enable a mass global construction of clean energy producing solar power stations that are either competitive with other fuels — or that just basically blow them away when it comes to price. And such high volumes of renewable energy construction around the world are providing some hope that humankind will be able to stave off the worst impacts of fossil-fuel spurred climate change. A greenhouse gas based of warming airs and waters that is already threatening keys species, putting Australia’s Great Barrier Reef in an existential crisis, and endangering the future of thousands of coastal cities as melting glaciers start to flood the world’s oceans.

Solar Power Stations For as Little as 65 Cents Per Watt

In the U.S., solar power stations now average about $1.10 cents per watt once all the cost of labor and construction is added in. For most instances, this price is competitive with highly polluting power stations like gas and coal. It’s about half the cost of nuclear energy. And solar prices are now also dipping below the price of new wind energy (which is also falling).

(GTM finds very low and falling prices for solar globally.)

In other regions of the world, solar energy is even less expensive. In the UK, Egypt, Mexico, China, and India, the cost of building a solar power plant is now $1.00 or less. A price which is now lower than the cost of a new advanced coal or gas power station. India, which boasts the least expensive construction costs for solar, can now build a renewable energy station for about 60 to 70 percent of the price of a comparable coal or gas plant at 65 cents per watt.

In this global economy, solar is now becoming cheaper than any other traditional source. It is also far cleaner than the other sources with the possible exception of wind. Solar has, by reducing costs so precipitously and by increasing access, become a game-changer both for the global energy market and for humankind’s prospects for reducing the considerable damage caused by fossil fuel based greenhouse gas emissions.

Subsidies vs Tariffs 

Enter Suniva, which is one of the world’s less efficient solar manufacturers. Based in the U.S., but majority owned by China, Suniva was unable to compete in a global market that produced solar cells for such low cost and high availability. This year, the firm filed for bankruptcy. The firm was unable to compete despite tariffs that the U.S. had already imposed on some solar panel importers. A set of tariffs that have already helped to make the U.S. solar market more expensive than other comparable markets. Tariffs that have arguably slowed U.S. solar adoption rates while doing little to actually protect less competitive manufacturers that would probably have eventually failed anyway.

The tariffs were, however, set in response to a legitimate gripe. Subsidies by China had probably created an unfair advantage for Chinese solar panel manufacturers. And these subsidies likely continue to generate advantages for such manufacturers in both China and in Southeast Asia. Subsidies that, in part, probably sped along Suniva’s bankruptcy and the approximate loss of 1.200 U.S. solar manufacturing jobs.

Suniva’s Selfish Suit Threatens to Wreck U.S. Solar Industry

Suniva’s response, however, is pretty overblown. One that threatens much of the solar market as it presently stands in the U.S. The corporation is asking for a $.40 floor on imported solar cell prices — which is basically double that of the lowest cost solar cell presently on the market. The company is also asking for a $.78 cent floor on import module prices — which is 45 cents higher than current lowest module spot prices. Such added costs would ripple through the U.S. solar production chain and would probably result in plant prices that range from $1.34 to $1.89 per watt. The reason is that the U.S. panel market is considerably dependent on imports and presently has few manufacturing plants that can produce cells and modules for prices low enough to prevent a big jump in industry-wide costs if Suniva gets its way.

(Evidence mounts that Suniva’s ITC case could sabotage the entire U.S. solar market. Image source: GTM.)

Such a jump in prices would result in considerable harm to the various solar companies that buy solar modules and build power plants, commercial and non residential systems by destroying a good deal of the present and rising solar demand in the U.S. This particular industry is now quite large and recent research by GTM indicates that as much as 66 percent of new construction could be halted if Suniva is allowed to so considerably distort the U.S. market. Ultimately, this risks the loss of thousands of jobs (not just the few hundred that have been lost in the manufacturing sector)– as much as 88,000 if the recent report by SEIA is correct.

So what’s the upshot? If Suniva’s suit goes through, it’s a big blow to both U.S. competitiveness and to our national responses to climate change. Chinese subsidies may, indeed, be distorting markets. But the solution that Suniva presents is basically to recommend drinking a hemlock that would kill off a big segment of the U.S. market while doing little to actually support U.S. solar manufacturing. Some jobs may trickle back as manufacturers try to meet the demand of a much reduced U.S. market. But the rest of the world will move on as incentives for U.S. manufacturers to improve dry up and as the home market itself contracts.

For the flip side of Chinese subsidies is that they not only subsidize Chinese solar manufacturing capacity, they also serve to advance a global energy transition through the mechanisms of direct investment and scaling. And there are so many larger benefits that the U.S. can take from the reduced pollution, increased secondary markets, increased competition, energy independence, and reduction of climate change based harms that are resulting from this major investment. The correct response is to meet investment and innovation with the same if we wish to reasonably compete. But the present federal administration appears to have completely lost sight of a better American future as it fights to regain the distorted ideal of an imagined past greatness.

Which is why Suniva’s ITC suit, in its present form, is at best short-sighted and at worst both selfish and broadly destructive.

Arctic Sea Ice Melt Analysis: The Concerning Development of a Beaufort Warm Pool During Late June

During 2016-2017, the Arctic sea ice, overall, has been hammered by far warmer than normal temperatures. The result has been continued record low Arctic sea ice volume and record low or near record low extent throughout the present period stretching from October of 2016 to late June of 2017. Now, the development of a pool of warm water in the Beaufort Sea even as a strengthening ridge is poised to inject more heat into this key region threatens to increase sea ice melt pressure as we enter mid-summer.

(Far warmer than normal conditions greatly impacted Northern Hemisphere sea ice during 2016 and 2017. Due to this heat spike, the sea ice is presently far more susceptible to summer melt pressure. Image source: NASA GISS.)

Counter-Trend Cooling in May — But Sea Ice Still in Record Low Ranges

Cooler than normal temperatures in the High Arctic during May and near average temperatures over the Arctic Ocean during June resulted in somewhat less less late spring and early summer melt than some had feared.

This counter-trend cooling has set up conditions where sea ice measures in both volume and extent have bounced closer to the 2012 line with PIOMAS departures remaining in record low ranges and JAXA and NSIDC extent measures tracking near second or third lowest on record.

(Region of interest for Beaufort warm pool development and predicted warm air injection over the coming days. The above graphic by Zack Labe compares present Beaufort and CAA conditions with those of last year when melt in the region was rapidly progressing.)

But despite a brief May respite from the most extreme heat of human-forced climate change, the Arctic sea ice remains very fragile and any added warmth at this time from either the ocean, the atmosphere or both can have an out-sized impact on end melt season totals.

Beaufort Warm Pool Development

Moving into Arctic mid-summer, primary factors of concern include both land and ocean surface temperatures as well as the potential development of various weather features harmful to sea ice. Trough development on the Russian side with ridge development over the Beaufort region is generally viewed as harmful — forming warm surface waters that can considerably erode old ice in the Beaufort and near the Canadian Archipelago, while generating a dipole temperature and pressure feature that produces winds which tend to enhance sea ice export through the Fram Strait.

(Warm surface water pool development in the Beaufort and Chukchi seas represents a melt hazard to sea ice if it continues to grow and gather heat. Hot spots currently forming in the Beaufort at 5 C above average in the DMI measure is therefore cause for some concern. The predicted development of a strong high pressure ridge injecting much warmer than usual temperatures into the region will tend to feed energy into these already-warm surface waters. Image source: DMI.)

Throughout June, this form of dipole has tended to emerge — with weak highs forming consistently over the Beaufort and with moderate-to-strong lows gathering on the Russian side centering on the Laptev Sea, but ranging into the Kara, East Siberian Sea, and on into the Central Arctic. This persistent dipole has also aided in the production of warm surface waters in both the Beaufort Sea and in the Chukchi. Sea surface temperatures in this region have already formed into a considerable warm pool with anomalies ranging from 2-5 degrees Celsius above average over an expanding region.

Predicted Injection of Warm Air of the Beaufort

During the coming days, a ridge extending over Northern Canada is predicted to drag a surge of warm air across both the Canadian Archipelago and the Beaufort Sea. Over-ocean temperatures in the Beaufort are expected to considerably vary above the norm — hitting as high as 48.6 degrees Fahrenheit (9.2 C) in some regions. An over-ocean value that is around 7-9 C above average for this time of year.

(Ridge development is expected to inject much warmer than normal temperatures over the already warm Beaufort Sea by July 2nd. This predicted event presents increasing risks of sea ice melt for a key Arctic region. Image source: Earth Nullschool.)

Since oceans tend to moderate both summer heat and winter cold, these are considerable local extremes. And in conjunction with a developing warm pool of ocean surface waters, such above average atmospheric readings represent a melt hazard to sea ice in the critical Beaufort basin and in adjacent regions. Ice in the Canadian Archipelago will also come under melt stress in the event that such a forecast trend develops. Meanwhile, the greatly reduced subset of multi-year ice floating just to the north of the Archipelago will also be subject to the warm air injected by the ridge as well as to the warming of nearby surface waters.

Risks Worth Monitoring

During 2012, the persistent development of a warm water pool in the Beaufort contributed to record low sea ice readings by late summer. This warm pool ate away at the ice edge, wrecking the multi-year ice even as it was eventually thrust into the Central Arctic by a powerful storm emerging over the East Siberian Sea during August. Similar warm pool formation at this time and continuing through July is cause for some concern, which is why a nascent warm pool development during late June is worth continued monitoring.

Wind and Solar Accounted For 57 Percent of New U.S. Generating Capacity Additions in First Quarter

Policy sure makes one heck of a difference. Thanks to legislation and investments by China, the U.S., Europe and numerous other countries around the world, solar energy has reached price parity or better with natural gas and coal over a growing subset of the globe. In the United States, fully 36 states in 2017 are seeing solar at parity with fossil fuel based generation. And costs for this new, clean energy source are expected to keep falling over at least the next five years as production lines continue to expand and technology and efficiency improves.

Wind, already competitive with natural gas and coal in many areas by the mid 2000s, is also seeing continued price declines as turbine sizes increase and industrial efficiency gains ground. As a result, the two mainstream energy sources most capable of combating human-caused climate change are taking larger and larger shares of the global power generation markets.

(Solar and wind continue to gain a larger share of new capacity additions than competing fossil fuel based generation. Image source: SEIA.)

This trend continued through Q1 of 2017 as about 4 gigawatts of new generation capacity or 57 percent of all new generation came from wind and solar in the U.S. Solar added about 2.044 GW, which was a slight drop from Q1 of 2016. Wind, however, surged to 2 GW — representing the strongest first quarter since 2009. In total, U.S. renewable generating capacity including wind, solar, hydro, biomass, geothermal and others is now at 19.51 percent of the national total. Expected to hit above 20 percent by year-end, renewables have now far outpaced nuclear (at 9.1 percent) and are swiftly closing on coal (at 24.25 percent).

Globally, 24 percent of electrical power generation was produced by renewables by the end of 2016. This share will again jump as 85 gigawatts of new solar capacity and 68 gigawatts of new wind are expected to be added during 2017. As a result, total renewable generation is now set to outpace global coal generation in relatively short order.

Such rapid adds in renewable capacity are being fed in part by expanding solar production around the world and, particularly, in China. During late 2016, solar manufacturing capacity in China had expanded to 77.4 GW per year — with more on the way. And even as production capacity continues to grow in China and across Southeast Asia, places like the U.S. (with Tesla’s Buffalo Gigafactory 2 alone expected to eventually pump out 10 GW of new solar cells each year), Canada, Turkey, Korea, and Mexico are also rapidly expanding the production pipeline. Meanwhile, the global wind production pipeline continues to make significant gains.

(By 2020, global wind and solar generating capacity is expected to roughly double. Rapid growth in renewable energy is a necessary mitigation for harms resulting from human-forced climate change. Image source. FIPowerWeb.)

The rapid additions to renewable energy capacity provide hope that the world will soon start to see falling carbon emissions overall. Such an event is key to reducing harm already coming down the pipe due to human-forced climate change as global temperatures begin to challenge the 1.5 C threshold during the next two decades and as CO2e (including CO2 and all other greenhouse gasses) levels threaten to cross the critical 550 ppm demarcation line.

The strong progress of renewables does not come without a number of concerning difficulties and challenges. These challenges are primarily political — with Trump’s backing away from Paris threatening to upset the emissions reductions apple cart and Suniva’s recent ITC challenge injecting uncertainty into the U.S. solar energy market. Meanwhile, fossil fuel based industry backers continue various attempts to sand-bag or, worse, reverse renewable energy growth.

Despite these various difficulties, renewables like wind and solar will likely continue to gain ground as markets expand, technology and efficiency continue to improve, and as states, nations and industries jockey to claim their own share of the growing renewable energy market windfall. The big question that should concern pretty much everyone, however, is will this expansion in renewables proceed fast enough to afford the world a much-needed chance to slake an extraordinary amount of climate change related damage that’s now moving rapidly down the pipe in our direction.

A Delaware-Sized Iceberg is About to Enter the Southern Ocean — Loss of Larsen C Ice Shelf Possible in Near Future

A rift in West Antarctica’s Larsen C Ice Shelf is about to expel a 1,000 foot tall, Delaware-sized iceberg into the Southern Ocean. The crack began to form in 2011. But over the past year, it has expanded rapidly. Now this massive, newly-forming iceberg hangs by just a thin 13 kilometer wide thread.

As you can see from the above Sentinel 1 animation posted by Adrian Luckman, rift progression has occurred in large leaps as pressure on the shelf reached various breaking points. New additions to the rift have often been in jumps of 20 kilometers or more of rift length in numerous instances over the past year. With just 13 kilometers of connecting ice remaining, the entire state-sized iceberg could now break off at any time.

According to Project Midas, late June observations show the crack continuing to widen at the rate of about 2 meters per day. So the larger section of the newly-forming berg is progressing toward the Southern Ocean at a rather rapid rate. And this movement is increasing strain on the small remaining ice bridge to the larger Larsen C Shelf.

Once the massive berg breaks off, researchers are concerned that it could precipitate a larger collapse of the Larsen C Ice Shelf itself. Such an event would be the third ice shelf loss along the Antarctic Peninsula during recent decades. A series of ice shelf collapses precipitated by warming oceans and atmospheres induced primarily by fossil fuel burning.

(Many cities are already suffering from rising ocean levels. However, future rates of sea level rise can increase considerably over present rates depending on how rapidly glaciers and ice shelves are taken down by human-forced warming. Image source: Tamino.)

Such ice shelf losses are a rather serious affair as they release the glaciers behind them — allowing these massive ice forms to enter the world ocean more rapidly and thus increasing the rate of global sea level rise. Already, numerous cities, islands and nations are under threat from oceans presently rising at the rate of 3.3 millimeters per year globally. But loss of buttressing ice shelves like Larsen C and others around Antarctica and Greenland may double the present rate of rise many times over.

At a recent meeting of over 250 U.S. Mayors in Miami to discuss how climate change is presenting a serious threat to cities, New York’s Bill de Blasio told reporters: “Miami Beach is facing, literally, an existential crisis.” But it’s not just Miami that’s under the gun. It’s pretty much every coastal town, city, state and nation around the world. And Larsen C is just one of the most recent sea level rise canaries to begin to show signs of ailing in the global warming coal mine.

U.S. Climate of Troubles: Record Heat Out West, Severe Floods in the East

Yesterday a record heatwave affecting 40 million people cracked pavement, grounded flights, threatened power grids and risked serious injuries across the Southwestern U.S. Meanwhile, today, a heavily moisture laden tropical storm Cindy is threatening to dump 10 to 15 inches or more of rain on parts of the U.S. Southeast. A pair of opposite weather extremes of the kind we’ve come to expect more and more of in a world that’s warmed by about 1.2 C above 1880s averages.

(Very extreme weather conditions settled over the U.S. on June 20. Today, Cindy is expected to bring extraordinary rainfall totals to the U.S. Gulf Coast. Video source: ClimateState.)

Record-Shattering Western Heat

Yesterday, the mercury struck a scorching 127 degrees F in Death Valley California — the hottest June 20th ever recorded for that heat-blasted lowland. Meanwhile, Death Valley-like heat spilled out over a large swath of the southwest. Phoenix fell just shy of its daily record as temperatures struck 119 F. And Las Vegas tied its all-time record of 117 F (which was set just four years ago on June 30th). Needles, Daggett and Barstow in California joined Kingman in Arizona and Desert Rock in Nevada to also break previous heat records as temperatures soared to between 111 and 115 F across these cities and towns.

(Record heat hammered the U.S. West on Tuesday spiking fire hazards, grounding planes, causing power outages and increasing the risk of heat injury. Image source: National Weather Service.)

All these severe high temperatures took a serious toll as both cities and citizens fell under blast-furnace-like conditions. In Phoenix, 43 flights were grounded. Aircraft could not generate enough lift for a safe take-off in the thin, low-density hot air. Total number flights grounded since Monday now tops 50 for the city — with more expected Wednesday when temperatures are expected to hit 118 F.

As flights were grounded in Phoenix, fires began to spark across the Southwest. Several fires ignited in Southern California including a large 950 acre blaze near Big Bear. In Utah, hundreds of people were forced to evacuate a ski town when a weed-killing torch ignited a swiftly spreading fire. And in southwest Arizona, a wildfire burned 8 structures as more than 100 firefighters rushed to contain the blaze. Firefighters across the southwest struggled against some of the most difficult conditions imaginable — extreme heat, blustery southerly winds, and rapidly-drying vegetation.

Record heat also overwhelmed grids when customers cranked up air conditioning and high temperatures put a major strain on power lines and transformers. With California temperatures climbing to historic levels yesterday, power outages were reported across Central Valley and on into the Bay area. Extreme warming of road surfaces caused highways to buckle even as hospitals prepared for a surge of various heat-related injuries from burns, to heat exhaustion, to heat stroke.

(Recent warming of ocean surfaces to well above average ranges off the U.S. West Coast have likely boosted the development of the recent western heatwave. Ocean surface warming is a signature condition of human-caused climate change. Image source: Earth Nullschool.)

A strong high pressure system and a large associated ridge aided by abnormally warm waters off the U.S. West Coast are the primary regional causes of the most recent heatwave. The pool of warm water in the Northeast Pacific — somewhat reminiscent of the Hot Blob that formed in the nearby ocean zones during 2014 and 2015 — appears to be boosting the development of upper level ridges and related surface heat over the region as temperatures climb to 10 to 25 F or more above normal for many locations. Despite recent record winter and spring rainfall for parts of the region, this new heatwave is starting to again advance drought conditions across the Southwest. Yet another hard shift in weather extremes from wet and cool to dry and hot that can likely be linked to climate change.

Cindy Ushers in Severe Flooding across the Gulf Coast

While the west scorches under extreme heat, the weather threat to the U.S. Southeast comes in the form of severe flooding. In the Gulf of Mexico, a sprawling Tropical Storm Cindy is interacting with a stalled frontal system to spike moisture levels in the atmosphere above the U.S. Gulf Coast. Already, between 3 and 9 inches of rain have fallen over parts of Louisiana, Mississippi, Florida and Alabama. But the slow-moving, heavy rain bearing Cindy is poised to dump still more.

(24 hour rainfall totals show that heavy precipitation in the range of 3 to 9 inches have already fallen across the Gulf Coast. Cindy is expected to bring even more over the coming days. Image source: NOAA.)

According to NOAA QPC predictions for the next week, as much as 8.5 additional inches of rainfall could impact already-flooded parts of SE Louisiana. And when all is said and done, the system is forecast to drop between 10 and 15 inches or more of rainfall over parts of the area. The storm is not presently expected to rival last year’s August rain event which dumped up to 30 inches over the same region. Of course, with climate change boosting rainfall potentials by warming the Gulf of Mexico and spiking atmospheric moisture and instability, the unexpected can certainly happen. Let’s just hope that’s not the case with Cindy. But 10-15 inch rainfall totals are certainly disruptive enough. And with some streets in New Orleans already seeing 2-3 feet of flooding as more storms rush in from the Gulf, this event is certainly far from finished.

Sweden Aims to be Carbon Neutral by 2045; Largest Pension Fund Ditches Climate Bad Actors

In a stunning victory for clean energy and climate progress, Sweden this week overwhelmingly passed a law that fully commits the country to carbon neutrality by 2045. Meanwhile, Sweden’s largest pension fund has divested from corporations it identifies as violators of the Paris Climate Accord. As a wise person recently said (see featured comment below) — this is “what real climate leadership looks like.”

Beating a Fast Path to Net Zero Emissions

Sweden’s most recent climate law, which flew through the Parliament by a 254 to 41 margin, aims to have the country producing net zero carbon emissions in less than three decades. This new measure moves the date for Sweden’s carbon neutrality forward by 5 years from 2050 to 2045.

Already a climate leader, Sweden presently gets about 85 percent of its electricity from hydropower, wind and nuclear energy. Across all sectors of its economy, Sweden has achieved the goal of 50 percent renewable energy fully 8 years ahead of schedule. The new measure doubles down on this already-powerful trend by further trimming carbon-based electrical generation while shifting larger focus to carbon emissions cuts from the transportation sector.

(Swedish electrical generation is dominated by hydro, nuclear, and wind power. Sweden aims to remove fossil fuels from electrical power generation while shifting transportation to EVs and biofuels by 2045. Image source: Electricity Production in Sweden.)

In order to achieve carbon neutrality, Sweden is pushing hard for rapid electrical vehicle adoption, switching remaining liquid fuels to biofuels, and to completely phase out its ever-dwindling margin of fossil fuel power generation. The result of these policies would be a country that primarily runs on renewable and nuclear power generation and that uses EVs and other alternative fuel vehicles for motorized transportation. Ultimately, Sweden aims to cut its presently low carbon emissions by a further 85 percent all while planting trees and developing carbon sinks to offset the rest by 2045.

Divesting From Climate Bad Actors

In a related move, Sweden’s largest pension fund, which manages the pensions of 3.5 million Swedish citizens, decided to divest money from various climate bad actors. The fund, AP 7, announced last week that it would pull investments from six corporations that it identified as being engaged in various violations of the Paris Climate Summit. These companies included: ExxonMobil, Westar, Southern Corp, and Entergy for fighting against climate legislation in the United States, Gazprom for oil exploration in the vulnerable Arctic, and TransCanada for building pipelines across North America despite widespread local opposition and obvious long-term climate impacts.

(AP 7’s divestment from climate bad actors is a major win for climate action advocacy groups like which nobly aim to leverage mass social, political and protest action to help spur a transition to 100 percent renewable energy in an effort to prevent serious global harm from climate change. Image source:

These moves were praised by climate action advocacy group’s Jamie Henn, Strategic Communications Director for the global grassroots climate movement, who stated:

“Sweden divesting its largest pension from Exxon proves you can’t claim to support climate action while funding and perpetuating climate change. Exxon knew about climate change half a century ago, and continues to sow doubt and bankroll climate deniers. With its core business model dependent on exploiting people and planet for profit, Exxon is in direct violation of the Paris agreement.”

Responsible Climate Action by Sweden

Sweden’s latest moves cast light on various agencies who have done so much to slow the pace of a much-needed response to climate change and a related energy transition while putting serious legislative muscle behind carbon emissions reductions. It’s a major win for the divestment and climate action movements — further calling into doubt the viability of a number of businesses who’ve predicated their future profitability on wholesale global harm. Sweden, by both moving forward its date for carbon neutrality and by moving large pension funds away from direct capital support of the fossil fuel industry continues to set an example for all by vividly underlining how decisively the rest of the world needs to act to catch up.

World Climate Stays in Uncharted Territory as May of 2017 Hits Second Hottest on Record

We’re currently in what should be a relatively considerable temperature trough following a strong 2015-2016 El Nino. But the globe hasn’t really cooled off that much.

In contrast, during the two year period following the 1998 super El Nino, annual global temperature averages subsequently cooled by around 0.2 C to about 0.64 C warmer than 1880s averages as a strong La Nina swept in. This post El Nino cooling provided some respite from harmful global conditions like increasingly prevalent droughts, floods, fires and coral bleaching events set off by the 1998 temperature spike. It did not, however, return the world to anything close to average or normal temperature conditions.

Warming Out of Context

(So far, 2017 temperature averages for the first five months have remained disturbingly close to what should have been an El Nino driven peak in 2016. Temperatures remaining so warm post El Nino are providing little respite from this peak warming. Meanwhile, the longer significant La Nina conditions hold off, the more extreme and out of context the post-2013 period looks from a global weather/climate perspective even relative to the significant warming occurring from the late 1970s through the early 2010s. Note the steep temperature spike following 2013 in the graph above. This should flatten out, step-wise, as La Nina conditions ultimately push against the larger surface warming trend [driven primarily by fossil fuel burning]. We thus await a La Nina stronger than the very weak late 2016 through early 2017 event with bated breath… Image source: NASA.)

During 2015 and 2016, the world was forced to warm much more intensely than during the 1998 event as very high and rising greenhouse gas concentrations (400 ppm CO2 +) met with another strong El Nino and what appeared to be a very widespread ocean surface warming event. Temperatures peaked to a troubling 1.2 C hotter than 1880s averages during 2016. An annual peak nearly 0.4 C warmer than the 1998 temperature spike. But unlike the period following the 1998 event, it appears that 2017 will probably only back off by about 0.1 degrees Celsius at most.

This counter-trend cooling delay is cause for some concern because a larger portion of the global surface heat added in during the 2015-2016 El Nino appears to be remaining in the climate system — which is lengthening some of the impacts of the 2015-2016 temperature spike and putting the world more firmly outside of the weather and climate contexts of the 19th and 20th Centuries.

(2017 temperatures aren’t trailing too far behind 2016’s record spike. A trend that is, so far, considerably warmer than 2015, which was the second hottest year on record. Image source: NASA.)

Record heat, drought, rainfall events, unusual storms, coral bleaching, glacial melt, wildfires, sea ice melt and other effects related to extreme global temperature will, therefore, not abate as much as some would have hoped. Furthermore, though current science does not appear to identify a present perturbation in the ENSO cycle (which may produce more El Ninos as the world warms), monitoring of that cycle for warming-related change at this time seems at least somewhat appropriate.

Second Hottest May on Record

According to NASA, May of 2017 was 0.88 degrees Celsius hotter than its 20th Century baseline — or 1.1 C warmer than 1880s averages when the world first began a considerable warming trend clearly attributable to fossil fuel burning and related human carbon emissions. This reading is just 0.05 C shy of the record warmest May of 2016. It’s also slightly warmer than the now third warmest May (0.01 C warmer) of 2014. And all of the top four warmest Mays in the present NASA record have now occurred since 2014.

(NASA’s second hottest May on record brought above normal temperatures to much of the globe. Disturbingly, the most extreme temperature departures above average occurred in the vulnerable Coastal regions of Antarctica. Small regions including parts of the North Pacific, the Northern Polar Region, the extreme South Atlantic, and the Central U.S. experienced below average temperatures. But these outliers were few and far between. Image source: NASA.)

Add May of 2017 into the present 2017 running average and you get a total of 1.19 C warmer than 1880s conditions. This is the second warmest first five months on record following 2016 at a very considerable 1.38 C above 1880s. It is, however, just about 0.01 C behind 2016’s annual average of 1.2 C above late 19th Century global temperatures.

It’s worth noting that most of the temperature spike attributable to the 2015-2016 El Nino occurred beginning in October of 2015 and ending in April of 2016. Somewhat milder months comparable to April and May 2017 averages followed from June through December of 2016 as a very weak La Nina followed. Since about February, Pacific Ocean conditions warmed into an ENSO neutral state where neither El Nino or La Nina dominated. NOAA’s present forecast calls for ENSO neutral conditions to continue as the Equatorial Pacific slowly cools again. So a continuation of present trends could leave 2017 rather close to the 2016 spike.

Forecast Trends

GFS model guidance for June shows somewhat cooler global conditions than in May. If this trend continues we will likely see the month range from 0.7 to 0.82 C above NASA’s baseline. If the GFS summary is accurate and this meta-analysis is correct, then June of 2017 will likely range between 1st and 4th warmest on record. Meanwhile, ENSO (El Nino Southern Oscillation) neutral conditions should tend to keep 2017 as a whole in the range of 1 C to 1.2 C hotter than 1880s averages — likely beating out 2015 as the second hottest year on record and keeping the globe in what basically amounts to uncharted climate territory.

Big Win For Solar Revolution, Public as Nevada Reinstates Net Metering

Back during late 2015 and early 2016, wealthy investors aligned with Nevada utilities in an attempt to kill off a wave of rooftop solar adoption rippling through the state.

Campaign money was promised, shady back-room deals were made, and in 2016, the state set forward a policy that would basically make it uneconomical for homeowners to purchase or maintain solar rooftops. Credits to homeowners with solar roofs who sold electricity back to utilities dropped from 12.5 cents per kilowatt hour to 2.5 cents.

This crushing blow to clean, distributed energy resulted in mass protest both from the Nevada public and from the industry itself. Demonstrations erupted in the Nevada capital as Solar City (now under Tesla), Sunrun, and Vivint all decided to pull the plug on state operations in an all-out boycott to protest Nevada’s anti-renewables policy. In total, 2,600 clean energy jobs were lost in Nevada as industries fled the state and solar adoption rates plummeted.

Many thought this was the short-term end for rooftop solar in Nevada. That residents wanting to tap the abundant, clean power source would have to wait for battery prices to drop enough for them to go off-grid. But since 2016, it appears that the Nevada government has now had a change of heart in the face of a powerful counter-lobbying campaign by the solar industry, progressive politicians, and the public. For yesterday, both Governor Sandoval and the state legislature reinstated a net metering policy that is far more benevolent to homeowners with solar roofs and the solar industry at large.

(Nevada Governor Sandoval signs new state law re-opening the state to the rooftop solar industry. Image source: Vote Solar Nevada.)

It’s worth noting that the new policy makes far better sense for Nevada — which has no fossil fuel resources to speak of, but possesses an abundance of sunlight and is home to Tesla’s Gigafactory 1. And the fact that Nevada ever turned against renewables at all is a testament to the harmful influence fossil fuel based utilities are sometimes able to exert on state governments. But this effort to stymie renewables and home solar ownership ultimately failed.

Assemblyman Chris Brooks, a Democrat who spearheaded a clean energy push in Carson City provided this gauge of Nevada public sentiment in Scientific American:

“A lot of folks would say, and you would be surprised, ‘Las Vegas has so much sun; why aren’t we putting solar on every roof in Nevada? People across the state, from many different demographics, many different socio-economic situations, all said, ‘Why don’t we use more solar?’”

The newly reinstated policy will provide utility buy-backs for home solar generation at no less than 75 percent of the retail rate (or around 8-9 cents per kilowatt hour) and would be phased to allow new solar purchasers to receive higher payback rates during early years of ownership to help defray system costs. This policy stability ensures that homeowners who buy solar will receive a good return on their investment.

And it’s something politicians in the state are pretty proud of. Republican Governor Sandoval suggested that the program be a model for other states looking to incentivize renewable energy as the bill was signed.

“I believe, humbly, it will be a national model across the country.” he said to a crowd of solar advocates at the signing ceremony. “I’m as competitive as it gets, and I want Nevada to truly be a leader in energy policy.”

The Rains of Antarctica are Coming — Warm Summer Storms Melted Texas-Sized Section of Ross Ice Shelf Surface During 2016

“In West Antarctica, we have a tug-of-war going on between the influence of El Niños and the westerly winds, and it looks like the El Niños are winning. It’s a pattern that is emerging. And because we expect stronger, more frequent El Niños in the future with a warming climate, we can expect more major surface melt events in West Antarctica (emphasis added).” — David Bromwhich, co-author of a recent study identifying massive summer surface melt in West Antarctica during 2016.


If you’re concerned about human-caused global warming, then you should also be concerned about ice. In particular — how warming might melt a miles-high pile of the frozen stuff covering the massive continent of Antarctica.

During recent years, scientists have become more and more worried as they’ve observed warming oceans eating away at the undersides of floating ice sheets. This particular process threatens numerous cities and coastal regions with swiftening sea level rise as ice margins melt and glaciers the size of mountain ranges clamor for release into the world’s oceans.

Major Antarctic Surface Melt Event During 2016

But another potential process in a still warmer world threatens to compound the impact of the heating waters that are already melting so many of the world’s glaciers from the bottom up — large scale surface melt.

(A major warming event during January of 2016 turned a Texas-sized section of Antarctica’s surface into slush. This occurred as a storm running in from the Southern Ocean delivered warm air and rainfall to sections of West Antarctica. Scientists are concerned that more major surface melt is on the way for Antarctica as the Earth’s climate heats up and that repeated warming and rainfall events in this typically-frozen region may further quicken rates of sea level rise. Image source: Earth Nullschool.)

During January of 2016, as a very strong El Nino was combining with human-caused global warming to spike atmospheric temperatures to 1.2 C above 1880s levels, something pretty strange and concerning happened. Over the course of about 15 days, a 300,000 square mile section of the Ross Ice Shelf surface and nearby lands over West Antarctica experienced melting. This mass slushing across Antarctica’s surface occurred as a warm storm swept in from the Southern Ocean (see image above) to deliver an unheard of rainfall event to the region.

West Antarctica is typically too cold for such weather. It is also often too dry. The region is well know by climate researchers as a frozen desert. But as human-forced climate change has warmed the nearby ocean, warm, moist winds blowing in from these heating waters have become more frequent.

Westerlies Interrupted by Warming Ocean

Antarctica is typically protected by strong westerly winds that keep both heat and moisture out. But a warming ocean environment, according to Ohio State researchers, is enabling El Nino to interrupt these westerlies and hurl increasing volumes of heat and moisture over the glaciers of Antarctica. In 2016, countervailing winds pushing against the typically prevailing westerlies bore with them an odd rainstorm that set off a massive surface melt event.

(Surface melt over a large section of West Antarctica lasted for as much as 15 days as heat and moisture from the surrounding ocean beat back a protective barrier of westerly winds and invaded the frozen continent. According to scientists, these events are likely to become more frequent and long-lasting as the climate warms. Image source: Ohio State University.)

When combined with already-active melt from ocean warming, surface melt could further serve to destabilize ice sheets and swiften sea level rise. This was exactly the concern that David Bromwich, an Antarctic researcher at Ohio State and co-author of the paper that identified this strange event highlighted in this statement (please see related Washington Post article here):

“It provides us with a possible glimpse of the future. You probably have read these analyses of West Antarctica, many people think it’s slowly disintegrating right now, and it’s mostly thought to be from the warm water eating away at the bottom of critical ice shelves. Well, that’s today. In the future, we could see action at the surface of these ice shelves as well from surface melting. So that makes them potentially much more unstable (emphasis added).”

It’s worth noting that this particular storm, though unusual and noteworthy, did not produce too much in the way of surface melt ponding. Instead, the storm turned a large section of the Antarctic surface to a slurpee-like slush. But this event did deliver a considerable amount of heat to the Ross Ice Shelf region. And repeated instances could serve to seriously soften this massive ice formation.

Eventually, as warming worsens, significant surface melt and flooding could help to shatter large buttressing ice shelves like Ross or even generate risks of surface glacial outburst flooding in instances where permanent surface melt lakes form behind an ice dam. But the primary concern at this time is that these warm rain events provide a compounding melt influence that adds to risks for more rapid sea level rise this Century.

Old Energy Left Behind — Equivalent of 7 Gigafactories Already Under Construction; Tesla Plans 10-20 More

In an interview with Leonardo DiCaprio during late 2016, Elon Musk famously claimed that it would take just 100 Gigafactories to produce enough clean energy to meet the needs of the entire world. As of mid 2017, in the face of an ever-worsening global climate, the equivalent of 7 such plants were already under construction while plans for many more were taking shape on the drawing boards of various clean energy corporations across the globe.

(Elon Musk shares climate change concerns, expresses urgency for rapid transition to clean energy in interview with Leonardo DiCaprio during late 2016.)

Tesla’s own landmark gigafactory began construction during late 2014. Upon completion, it will produce the Model 3 electric vehicle along with hoards of electric motors and around 35 gigawatt hours worth of lithium battery storage every single year (a planned output that Tesla said it could potentially triple or more to 100-150 gigawatt hours). During May, Tesla stated that it would set plans for four new gigafactories after Model 3 production began in earnest late this summer. And this week, Elon Musk announced an ultimate ambition to construct between 10 and 20 gigafactories in all. For reference, so many gigafactories could ultimately support vehicle production in the range of 12 to 24 million annually.

Racing to Catch up With Tesla

Tesla’s ramp-up to clean energy mass production, however, is not going unanswered. In China, CATL is building a gigafactory that by 2020 will produce about 50 gigawatts of battery packs every year. This massive plant is the centerpiece of China’s push to have 5 million electrical vehicles operating on its roads by 2020. It’s a huge facility that could outstrip even the Tesla Gigafactory 1’s massive production chain.

Meanwhile, another 11 facilities under construction around the world will add around 145 gigawatts of additional battery pack production capacity by the early 2020s as well. Add in both China’s CATL and Tesla’s Nevada battery plant and you end up with 230 gigawatts of new battery production — or the equivalent to just shy of 7 gigafactories that are already slated for completion by around 2020.

(Steep climb in EV adoption pushes global fleet to above 2 million during 2016. Swiftly dropping prices and expanding production chains will help to drive far more rapid adoption during 2017-2020. Massive factories producing EVs will also help to speed larger energy transition away from fossil fuels. Image source: International Energy Agency.)

Race to Win the Energy Transition 

According to news reports, the big-ramp up in battery production has already driven prices down to $140 dollars per kilowatt hour. That’s a major drop from around $550 dollars per kilowatt hour just five years ago. An amazing trend that is expected to push batteries for electrical vehicles down to below $100 dollars per kilowatt hour by or before 2020, and to around $80 dollars per kilowatt hour not long after. This means that battery packs for vehicles like Nissan’s new Leaf, the Chevy Bolt, and Tesla’s Model 3 are likely to range between $5,000 and $7,000 dollars in rather short order. A price level that will allow EV production at cost parity with similar fossil fuel driven vehicles within the next three years.

But ambitions appear to go well beyond just the transportation industry. Based on Musk’s earlier assessment, it appears that he’s aiming to control a 10-20 percent stake in the larger global energy market. An aspiration aided both by the innate fungibility of battery pack production (after-market EV batteries can be resold to the energy storage market) together with Tesla’s recent Solar City acquisition. It also appears that he is helping to spur a race between various companies and nations for new, clean energy, leadership. And with so much momentum already building behind the big clean energy push, it appears the choices for present energy and transport leaders are either to join the race or get left behind.
