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.

New Study: Ice Sheet Retreat Led to Rapid Methane Hydrate Release at End of Last Ice Age

Andreassen et al. found evidence of large craters embedded within methane-leaking subglacial sediments in the Barents Sea, Norway. They propose that the thinning of the ice sheet at the end of recent glacial cycles decreased the pressure on pockets of hydrates buried in the seafloor, resulting in explosive blow-outs. This created the giant craters and released large quantities of methane into the water above. — Science


At the end of the last ice age, a warming world released a portion of its carbon stores into the atmosphere. The result was, ultimately, an increase in atmospheric CO2 by around 100 parts per million and in increase in atmospheric methane by around 300 parts per billion.

This increase in greenhouse gasses was a direct response to the Earth warming by approximately 4 degrees Celsius over the course of about 10,000 years. Under a present human-forced warming that is currently 1.2 C above late 19th Century averages and that is predicted to reach between 3.3 and 7 C warming this Century if fossil fuel burning continues, it is important to consider what additional carbon forcing the Earth System will produce under such an extreme and short-term temperature departure.

A new study recently published in Science indicates that these massive craters in the sea bed off Svalbard formed as methane hydrate erupted from the sea bed when ice sheets retreated at the end of the last ice age. Many of these craters are over a kilometer wide. Image source: K. Andreassen/CAGE.

One subject of concern is the behavior of methane hydrate deposits under warming conditions. It is estimated that upward of trillions of tons of hydrate exist in various frozen deposits around the world. And that even a fractional release from these deposits could contribute to the increasing greenhouse gas overburden in our atmosphere and further exacerbate warming. A potential for such a release in the short term would add risk of increased warming this Century on top of planned emissions from human fossil fuel burning — adding urgency to already necessary rapid emissions cuts (and a related swift transition to renewable energy based economies).

Paleoclimate Evidence of Massive Hydrate Release

This past week, a new study entitled — Massive blow-out craters formed by hydrate-controlled methane expulsion from the Arctic seafloor — lends credence to concerns regarding hydrate release as a potential amplifier to human warming. The study found that as ice sheets retreated and as pressure was relieved from the sea floor near Svalbard 12,000 years ago, pockets of methane hydrate rapidly migrated toward the surface as they turned to gas. This newly gasified methane formed large, high-pressure, mounds on the sea floor. Such mounds were unstable. Sensitive to changes in the local environment, they generated explosive outbursts which released considerable volumes of methane into the ocean and ultimately also added heat-trapping carbon to the Earth’s atmosphere.

The lead author of the study, Karin Andreasson, a professor at the CAGE Centre for Arctic Gas Hydrate, Environment and Climate noted in last week that:

As [the] climate warmed, and the ice sheet collapsed, enormous amounts of methane were abruptly released. This created massive craters that are still actively seeping methane.

Though the methane craters formed off Svalbard around 12,000 years ago as the ice sheet retreated, they are linked to deeper methane pockets and are still leaking gas into the ocean today. Image source: Andreia Plaza Faverola/CAGE.

The researchers characterized these blow-out mounds as similar to those that have recently been forming in the Russian permafrost in places like Yamal and Yakutia. And their research indicates that a process like the one that occurred off Svalbard at the end of the last ice age may be at play as permafrost thins and as gas beneath this cap of frozen soil more rapidly migrates toward the surface — creating unstable blow-out mounds. Researchers also indicated that places presently locked in surface ice — like Greenland and Antarctica — could generate further methane blow out risk as ice sheets melt, withdraw and remove pressure from the methane deposits beneath them.

Conditions in Context

These are important findings due to the fact that paleoclimate evidence of past large-scale hydrate release provides a study-identified mechanism for how permafrost hydrates and gas deposits are being liberated due to present warming, how such warming may increase their rate of liberation in the future, and how ice sheet withdrawal could contribute to this hydrate liberation trend. What remains highly uncertain is the ultimate volume of hydrate response to a given level of warming over a given period and how significantly such releases would contribute to the already very considerable heat forcing provided by human emissions. That said, the new study does add to serious concerns regarding the potential for future warming and greenhouse gas levels — which will tend to be higher than present model studies indicate due to generally not accounting for these kinds of Earth System carbon feedbacks.

Trump Against The World — Withdrawal From Paris Threatens Both Global Security and Economic Competitiveness

Energy. It’s the foundation for any modern economic system.

But if the extraction and use of that energy generates harm in the form of serious negative health impacts and ultimate environmental destruction, then it is accurate to say that continuing such energy use is unsustainable. That, ultimately, economies dependent on energy in the form of oil, gas, and coal will fail even as the world suffers the broadening calamities of an ever-worsening climate. Even the U.S. military is concerned about the ever-worsening situation — calling climate change a global threat multiplier.

For decades, a slow progress has been made toward accessing sustainable forms of energy like wind, solar, and electrified transportation. Such a transition away from fossil fuels and toward these new energy sources was accurately seen by many experts as the best way to ensure that humankind avoided the worst destabilizing impacts of emissions-driven climate change while also retaining access to the benefits provided by modern technological systems. And since at least the 1980s a political struggle has been underway between the agencies supporting a renewable energy transition and those opposing it. Related to this struggle are the various global climate summits and emissions reduction agreements. For it is abundantly clear to anyone following the issue that if the nations of the world do not curtail and ultimately halt the burning of fossil fuels, then, sooner or later, a catastrophic climate state will be reached.

The Paris Climate Summit — A Breakthrough Global Consensus

In December of 2015, as the global climate situation continued to worsen and the cost of renewable energy systems plummeted, 195 nations signed a landmark climate agreement in Paris. The agreement aimed to dramatically reduce global carbon emissions even as it set aside funding to begin to prepare for the already-worsening impacts of human-caused climate change. Under the non-binding agreement, these nations pledged to reduce carbon emissions enough to take the world off a very dangerous business-as-usual emissions pathway. If nations honestly met their pledges under the first phase of the agreement, the amount of warming during the 21st Century could be reduced from a rather catastrophic 4.5 degrees Celsius to a still very damaging 3.3 degrees Celsisus.

(Parties of the Paris Climate Summit are shown in orange, signatories are shown in green and light blue. Those not involved in the summit are in purple. Trump’s withdrawal from the accord is contrary to majority sentiment both at home and abroad. Image source:  L. Tak.)

This initial reduction pathway was not ideal. It was, however, quite substantial. A longer-term pledge was made to try to keep global temperatures below 2 C (and even less than 1.5 C) — a goal that assumed far more aggressive emissions cuts in the years to come. But what the initial Paris pledges did achieve was to firmly set the world on a course in which fossil fuel dominance of energy systems (and their related harmful emissions) would likely become a thing of the past by or before mid century even as serious economic and political muscle pushed forward the emerging clean-technology revolution.

This first phase of carbon emissions reductions would be achieved by primarily shifting away from coal burning and relying more on natural gas, but also by starting to fast-track renewable energy adoption. India and China, in a critical measure, committed to de-emphasize coal plants as a basis for future economic development and instead turned more toward wind and solar energy adoption.

Developed and less developed nations alike pledged billions of dollars for a Green Climate Fund that would help the poorest countries in the world both move away from fossil fuel burning and adapt to already emerging climate impacts. Meanwhile, business leaders began to see some major opportunities coming through the development of less harmful industries.

(Trump’s withdrawal from the climate summit could sabotage key emerging U.S. industries such as electrical vehicle production from places like Tesla’s Gigafactory. Image source: Tesla.)

In all of this process and negotiation, the U.S. took a leading role. And for good reason. For a number of the key industries and technologies that would enable these emissions reductions were emergent in the United States. And U.S. citizens and industry both stood to benefit from the clean energy revolution and energy independence that would inevitably follow. But these new industries depended in part on policy support and direction provided by communities, states and nations both at home and around the world. Industries that would ultimately provide hundreds of thousands of jobs and, more importantly, create a far more virtuous and advanced economic system than that presently supported by old and dirty oil, gas, and coal.

Trump’s Withdrawal From Paris Meets With Stiff Resistance at Home and Abroad

This week, by withdrawing from the Paris Climate Summit, President Trump intentionally threw a monkey wrench into this potential for American leadership during the 21st Century. The U.S. is now one of just three countries not to join the agreement. Nicaragua abstained because that vulnerable country saw the agreement as not going far enough (viewing non-binding provisions as lacking force). Syria failed to sign due to ongoing internal strife. The U.S. signed the agreement under a far-wiser Obama administration. Under Trump, the nation has no excuse or substantive reason to withdraw. And despite much false talk coming from the Administration about how ‘Paris hurts America,’ Trump’s move amounts to little more than clinging to a sinking economic ship while leaving the door wide open for other countries (such as China, India, Japan, or European nations) to take the lead on clean energy. Because, to be clear, coal’s fortunes are plummeting even as renewable energy’s become rosier and rosier. And this is a systemic issue that Trump has little power to change.

It’s worth noting that a substantial coalition of cities and states within the U.S. are pledging to go ahead with Paris implementation despite Trump’s failure. For according to recent news reports, governors from California, Washington, Oregon, Hawaii, Colorado, New York, Massachusetts, Vermont, Connecticut and Rhode Island have joined to continue working toward the targets of the global climate accord. Meanwhile the European Union is seeking ways to work with both these governors and with major businesses such as 3M, Bank of America, Campbell Soup, Cargill, Citigroup, Coca-Cola, Corning, Dow Chemical, DuPont, General Electric, Goldman Sachs, Johnson & Johnson, JP Morgan Chase, Morgan Stanley, Pacific Gas and Electric, Procter & Gamble, Tesla, Virgin Group and the Walt Disney Company, to assist the U.S. in hitting its emissions targets, even without Trump-based federal support.

This coalition of the hopeful and willing is further joined by 211 U.S. cities which alone represent 54 million American citizens. Meanwhile Trump’s approval rating at home has plummeted due to his withdrawal from the agreement even as recent polling data shows that nearly 6 out of 10 Americans support the Paris Climate Agreement and oppose scrapping it. In the end, when it comes to Paris and climate change it appears that it’s Trump against both the larger U.S. and the rest of the world.
