After a Brief Respite, Climate Change Enhanced Drought is Returning to the U.S.

Unseasonable warmth across the American West and overall dry conditions across the South is causing drought to expand throughout many parts of the United States.

According to the U.S. Drought Monitor, most of the southern half of the United States is presently experiencing abnormally dry or drought conditions. Meanwhile, an intense drought that has remained in place over the Dakotas and Montana for multiple months continues to persist.

Severe drought conditions are now present in the south-central U.S. with exceptional and extreme drought expanding through Arkansas, Oklahoma, Texas, Louisiana and Missouri. Deepening drought in California and Texas are notable due to the fact that Southeast Texas recently experienced record rainfall due to Hurricane Harvey and California experienced a very wet winter and spring period from 2016 to 2017. Somewhat milder drought is also spreading through the Southeast.

Re-expanding Southern California drought is also enhancing record wildfire activity in that state.

Much Warmer than Normal Temperatures

A strengthening La Nina in the Equatorial Pacific is helping to generate a drought tendency for the Southern U.S. However, various climate change related features including above normal temperatures and a persistent high pressure ridge in the West are lending intensity to the rising drought regime.

(U.S. 30 day average shows much warmer than normal conditions for the lower 48 with extreme warmth prevalent over the American West. Image source: Global and Regional Climate Anomalies.)

Over the past 30 days, temperatures for the U.S. as a whole have been 1.52 C above average (see image above). Much of this excess heat has been concentrated over the West, with mountain and Pacific regions seeing between 4 and 5 C above average temperatures.

Excess heat of this kind helps to speed the drying of soils and vegetation by increasing the rate of evaporation. A condition that can lead to flash drought — whose incidence has been expanding in lock-step with the human-forced warming of the globe.

A Ridiculous Ridge

Linked to the western heat and drought is a strong and persistent high pressure ridge. One that has hit a very intense 1041 hPa pressure as of Monday afternoon over the U.S. Mountain West.

(Very intense high pressure ridge over the U.S. west is presently locking in both warmer than normal and drier than normal conditions. Image source: Earth Nullschool.)

Persistent ridging of this kind was a key feature of the recent 2012 through 2017 California drought. Some climate studies have identified a tendency of these kinds of strong western ridges to form as Arctic sea ice recedes. And during the past decade, strong high pressure ridges have been a rather consistent and significant climate feature for the U.S. West. It is also notable that formation of more powerful ridging features during the fall and winter help to strengthen the Santa Ana winds — which fan California wildfires.

Present drought is nowhere near as intense as it has been during recent years. Especially in California which during 2017 has experienced a bit of a respite. However, with La Nina gaining traction in the Pacific, with global temperatures now in a range between 1.1 and 1.2 C above 1880s averages, and with persistent ridging again taking hold over the U.S. West, the risk of a return to intense drought — especially for the Southwest — is increasing.

Southern California Fires Expand to Over 255,000 Acres as Conditions Worsen

On Sunday, driven by above normal temperatures and fanned by warm winds, the Thomas Fire in Ventura County, California rapidly expanded. This resulted in a loss of containment as the blaze jumped fire breaks — placing parts of Santa Barbara under seige.

(Smoke plumes from the Thomas fire as seen by a webcam located atop Santa Ynez Peak, a 4300′ mountain 17 miles northwest of downtown Santa Barbara.)

This single fire, as of Monday morning, covered 230,000 acres. At that time, it was the fifth largest fire in California history. It was burning in December. And, at the time, the fire was continuing to swiftly grow.

Five other fires burning in Southern California together cover an additional 25,000 acres. As a result, approximately 255,000 acres are now burning in this region of the state.

Firefighters had hoped that predicted milder Santa Ana winds would afford them a chance to gain an advantage over these fires this weekend. But this didn’t happen. The western high pressure ridge strengthened. Local temperatures increased to well above the seasonal average. And though winds subsided somewhat, very dry conditions dominated.

Due to the worsening situation, 25,000 structures are now threatened by the fires — up from 20,000 earlier this week. More than 320 structures have been burned or destroyed. More than 95,000 people remain under evacuation orders. And more than 85,000 people are without power. Tragically, the fires have now claimed their first human life as well.

Unfortunately, warmer than normal, dry and windy conditions are expected to continue through at least Friday, December 15th. Resulting in a long running period of heightened fire danger. These climate change related features are driven by a very persistent high pressure ridge over the North American west. A feature that has been linked to loss of sea ice and a warming Arctic in some climate studies.

Overall, climate change is worsening fire danger out west. During summer, hotter and drier conditions are intensifying the California fire season. And during fall through winter, the climate change associated warming, drying and strengthening of the Santa Ana winds is enabling the eruption of very large city-threatening fires during the winter months.

As Climate Emergencies Rise — A Call For Action

With climate change enhanced wildfires raging across California during December, now is exactly the time to redouble our resolve to fight against the causes of such widespread destruction. To enact policies aimed at reducing the force of a rising crisis that continues to impact so many of our people with increasing intensity.

In California today, there is a move afoot to set a deadline for banning the very fossil fuel based vehicles that have fanned the fires of climate change across the state. To resolve, by 2040, to take gas powered cars off the road.

Phil Ting, a San Francisco Democrat and sponsor of this legislative drive, notes that for the State to meet its greenhouse gas reduction targets, it’s going to have to transition away from fossil fuel based vehicles. Such vehicles represent more than 1/3 of all state carbon emissions. And the state can’t effectively address the carbon dioxide emissions that drive climate change disasters without also directly targeting the number of fossil fuel based vehicles in operation.

(According to California’s Air Resources Board, nearly 38 percent of the state’s carbon emissions are due to transportation.)

New electrical vehicle (EV) technology is enabling just such a move. According to Ting:

“The market is moving this way. The entire world is moving this way. At some point you need to set a goal and put a line in the sand.”

If California sets a policy to ban fossil fuel based vehicles by 2040, it will join a growing number of cities and states that have already set similar goals. These include France, the United Kingdom, India, Germany, and Norway. Meanwhile, China is pursuing very aggressive incentives to increase the number of EVs as a means of combating terrible local air pollution and climate change.

Movement by cities and states to ban fossil fuel vehicles and incentivize EVs has an out-sized impact. It signals automakers that EV preference by government is becoming widespread. And because manufacturers have limited capital to spend on new vehicles, this drives a manufacturing preference as well.

(In this National Renewable Energy Laboratory study, the most rapid carbon emissions reductions were achieved in scenarios where large-scale EV deployment was combined with wholesale replacement of coal, oil, and gas fired electricity generation with renewable sources like wind and solar.)

Since EVs are more efficient that internal combustion engine based vehicles, they greatly reduce carbon emissions when tied to even traditional grids. But when linked to renewable power sources like wind and solar, EVs produce zero emissions in operation. This combination enables a far more rapid rate of carbon emission reduction.

In addition, the manufacturing base for EV batteries can also be used to build storage systems for intermittent wind and solar energy. This enables the removal of fossil fuel emitting coal and gas fired generators held in reserve for times when the wind doesn’t blow or the sun doesn’t shine even as the EVs themselves remove the need for oil based transporation. Such a manufacturing chain also opens up a new market for auto manufacturers — a fact that both Tesla and Hyundai have learned to their benefit.

Because EVs are based on electronic technology that is closely tied to the information age, they can benefit both from synergistic related economies of scale and from various innovations and breakthroughs. This means that EVs already outperform fossil fuel based vehicles in a number of areas. A performance advantage that is increasing and will likely overcome most traditional vehicles by the early 2020s. Because of this advantage, EVs would probably ultimately win out over time. However, the present climate crisis lends urgency to speeding their rate of adoption and in accelerating the rate of harmful fossil fuel based vehicle replacement.

Rise of the Fimbul Fires: Climate Change Enhanced Jets of Flame Rage Across Southern California

Some say the world will end in fire. Some say in ice. From what I’ve tasted of desire. I hold with those who favor fire… — Robert Frost

I am Lorn Sparkfell, guardian of First Frost, without which the world will burn. — Luthiel’s Song, The Death of Winter

*****

Fimbul is an old icelandic word for mighty, giant, great. It is an archaic word that has fallen out of modern use. But considering the fact that the fires now ripping through Southern California are both out of the context of recent milder climates and have explosively expanded to gigantic proportion, it is perhaps time that we should re-introduce the term.

(Photograph of Southern California Fires taken from the International Space Station on December 7 of 2017.)

Sections of Southern California are now experiencing never-before-seen levels of fire hazard as winds gusting to near 80 mph across the region are fanning five out of control blazes. The fires are burning during what should be the cooler month of December. But cool conditions have eluded that part of the state. And the blow-torch like Santa Ana winds that are fanning the flames are being enhanced by conditions consistent with human-caused climate change.

Today, the fire index for Southern California is 296. The threshold for an extreme fire index is 165. And 296 is the highest fire index So Cal has ever experienced according to local firefighters. Fire index is a measure of fire risk. So, if these reports are correct, this region has never seen fire danger hit such an extreme intensity.

(Hurricane Force Winds Fuel Massive Wildfires in Southern California from ClimateState.)

Five fires now burning across Southern California have consumed upwards of 120,000 acres — or a region larger than Atlanta. The Thomas Fire in Ventura County is the largest at approximately 96,000 acres. The Rye Fire, Creek Fire, and Skirball fire all continue to burn. And a new fire — the Horizon Fire in Malibu — has recently ignited. None of these fires are more than 15 percent contained. So all are effectively still out of control.

In total, approximately 20,000 buildings are threatened by fire with more than 300 homes and businesses burned already. 200,000 people are under evacuation orders — enough to fill a relatively large city. Thankfully, there have been no reports of loss of human life so far. But animals, including these horses, haven’t been so lucky.

(Average temperatures across the U.S. West were around 4 C above normal for the entire past 30 day period. This is not at all typical. Image source: Global and Regional Climate Anomalies.)

Climate change skeptics and deniers will try to say that such events are normal for California. That fires always happen. That weather is variable. And tell you five or six or seven other kinds of hogwash.

But the fact is that these conditions are not normal. That California has just experienced its worst fire year on record. That the incidence of large fires in the West has risen fourfold since the mid 1980s. And that report after report after report are linking presently worsening fire conditions in the region to climate change.

Other politically motivated individuals will tell you that now is not the time to discuss climate change — by stating that responding to the disaster itself is more important that examining causes. This is also a red herring — as any effective disaster response will include a responsible review of causes.

To this point, if we are to be effective in both responding to this disaster and in reducing future harm, we should look seriously at the underlying causes that are making fires in places like California worse. And if we are exploring why these Fimbul Fires are happening now, then the big issue is climate change — writ large.

Winter is Supposedly Coming; So Why is California Burning?

As forecasters expect a warming climate will make Santa Ana winds more frequent and faster, that Santa Ana blowtorch is likely to do a lot more damage to the developed parts of the state. — One of the conclusions of a recent climate study.

You can only imagine the impact this weather is having. — Los Angeles Fire Chief.

*****

The popular refrain these days is that ‘winter is coming.’ But for California and the North American West, this is clearly not the case.

(Four large wildfires burn across Los Angeles in this December 5 satellite shot. Image source: NASA Worldview.)

Conditions across the West have been drier lately. Hotter lately. A lot less winter-like during the winter season lately. Add in the fact that climate change is expected to increase the strength of the wildfire-sparking Santa Ana winds and this trend of ebbing winter is a rather serious factor.

The very reason why we use the words — fire season — is due to the fact that fire is more prevalent when it is hotter, when it is drier, and when the dry winds blow more strongly. For California, fire season happens twice a year — once in early summer and again in autumn as the dry Santa Ana winds begin to howl.

(Consistent unseasonal heat and the development of powerful high pressure ridges over the North American West amplify the Santa Ana winds and set the stage for more severe wildfires. This week, a strong ridge and related abnormal warmth and drought helped to fan a historic Los Angeles outbreak. Image source: Climate Reanalyzer.)

The Santa Ana season lasts from October through April. It notable due to the fact that it tends to threaten more heavily populated areas. Its primary mitigating factor — cooler winter weather — is receding. And, according to this research, the same factors that are warming the U.S. West are also making the Santa Ana winds blow stronger. So we have good reason to believe that the effects of human-caused climate change are making California’s fall and winter fire season considerably worse.

Today is December 6, just a little more than two weeks before the Winter Solstice. Seasonally, we are at the gates of winter. Winter should be coming. But, instead, we have drought in Southern California. Instead we have had consistently warmer than normal weather over the past 30 days. Instead we have 70 mile per hour Santa Ana winds raging over withering peaks and through the drying valleys. These are conditions consistent with a fire season amplified by climate change. Not with normal winter.

And today, in Los Angeles alone, we have four fires raging simultaneously.

The largest fire, the Ventura Fire, has now burned more than 65,000 acres. It threatens 12,000 buildings. And it is already estimated to have consumed at least 150 of these structures. The fire has cut off power to upwards of 250,000 people and has forced numerous closures and evacuations.

The Creek Fire, Rye Fire, and Skirball Fire have reportedly burned an additional 15,000 acres and forced more than 150,000 people to evacuate. The Skirball fire is threatening the Getty Museum even as it has forced the closure of a section of highway 405. This 150 acre fire is also encroaching upon a 28 million dollar home owned by right wing media mogul — Rupert Murdoch. Notably, Rupert has used his media empire to support the views of climate change deniers and has called rational concern over climate change related risks ‘nonsense.’ Today, one of his many homes may burn as a result of such ‘nonsense.’

(Present location and extent of Los Angeles wildfires. Image source: Google Maps.)

In total, more than 1,000 firefighters are presently battling these four fires around the Los Angeles region. And the risks to the city are now as high as they have ever been. For on Wednesday, weather forecasters are calling for Santa Ana winds to continue to gust as high as 70 miles per hour. With the strength of these powerful fire-inducing winds peaking on Thursday as gusts are predicted to hit as high as 80 miles per hour. The winds will loft sparks and burning material from the fires and drop it over the city — creating nightmare conditions for firefighters trying to contain the four blazes. Red flag warnings — indicating that conditions are ideal for fire combustion — are expected to remain in place over Southern California through Friday.

U.S. Electrical Vehicle Sales Rose by 30 Percent in November, Likely to Hit Near 200,000 by Year End

Good news continues in the U.S. on the renewable energy front where electrical vehicle sales increased by about 30 percent in November of 2017 vs November of 2016.

In all, 17,178 electrical vehicles sold on the U.S. market in November. This number compares to 13,327 sold during November of 2016. Top selling brands for the month were the Chevy Bolt EV, The Tesla Model X, the Chevy Volt, the Toyota Prius Prime, and the Tesla Model S. The Chevy Bolt topped the list of monthly best sellers with nearly 3,000 vehicles going to owners during the month. The top annual seller remains the Model S (at 22,085 estimated sales so far) — which the lower-priced Bolt is unlikely to surpass this year.

(Over the past few years, the performance of electrical vehicles has been steadily catching up to or outpacing that of conventional fossil fuel vehicles. The Tesla Roadster by 2019-2020 will have a 620 mile range, hyperfast charging, a top speed of 250 mph, and be able to go from 0-60 in 1.9 seconds. A combined set of specs that no gas guzzler could hope to match. By 2022, most EVs will cost less and perform better than their comparable fossil fuel counterparts. Image source: Tesla.)

Total electrical vehicle sales for the year so far has hit nearly 174,000 through November. This compares to 158,614 for all of 2016. Given that December is often a top sales month and that Model 3 production is continuing to ramp, it’s likely that final sales for 2017 will hit close to or exceed the 200,000 mark for the year in the U.S.

Model 3 Production Ramp Rate Still a Mystery

Model 3 sales will likely continue to ramp through December as Tesla works through scaling production. Considering the fact that there are more than 500,000 Model 3s on order, the big question is — how fast? For even if Tesla were able to produce 10,000 Model 3s per week, it would take more than a year to fill all the orders.

Production is presently considerably lower. But it more than doubled in November to an estimated 345. A similar rate of increase would result in 800 of the vehicles being sold in December. Meanwhile, the company plans to be making 5,000 Model 3s per week by Q1 of 2018.

There are some indications that Tesla is preparing for a start of mass market releases. It is filling an LA Model 3 distribution site even as it has opened up ordering to customers outside of employees. Meanwhile, Panasonic recently announced that battery production issues will soon clear. Which raises the possibility of a faster ramp going forward.

Updated Nissan Leaf Begins Mass Production

New developments also include the start to mass production of the 2018 Nissan Leaf in the U.S during December. The 2018 Leaf features longer range (150 miles), lower cost (700 dollars less) and higher performance (more horsepower) than the previous Leaf. And it will be followed on by a (higher-priced) 225 mile range version in 2019 which will put it in a distance capability class similar to that of the Bolt and the base line Model 3.

Electrical Vehicles — Key Aspect of the Renewable Energy Transition

In context, solar energy, wind, and battery storage are the triad of new renewable energy systems that have the serious potential to really start cutting down global carbon emissions as they replace fossil fuels.

All these energy systems are getting less expensive. All have what they call a positive learning curve. And all can work together in a synergistic fashion while leveraging technological advances. Economic advantages that fossil fuel based systems lack.

In addition, renewable energy sources help to drive efficiency, even as they clean up transportation, power generation, and manufacturing chains they are linked to by producing zero carbon emissions in use.

(By transitioning to renewable energy as the basis for economic systems, we can dramatically reduce global carbon emissions. In order to stave off very harmful impacts from climate change, this transition will have to be very rapid. In the best case, more rapid than the scenario depicted above. Video source: IRENA.)

On the battery storage side, electrical vehicles are a crucial link in the battery development chain. As electrical vehicles are mass produced, this process drives down the cost of batteries which can then be used to store electricity and to replace base-load fossil fuel power generators like coal and gas plants. Meanwhile, battery electrical vehicles are considerably more efficient than gas or diesel powered vehicles and those linked to wind and solar or other renewable energy sources emit zero carbon in use.

Both electrical vehicles and other renewable energy systems have a long way to grow before they provide the same level of energy produced by dirty fossil fuels today. This large gap represents a great opportunity to cut back on the volume of harmful gasses hitting our atmosphere in the near future.

Deadly California Wildfire Erupts in December, Forcing Thousands to Flee

Last night a 500 acre fire exploded to massive size — raging over the hills of Ventura County in Los Angeles. Fanned by strong Santa Anna winds, the fire ballooned to over 45,000 acres by Tuesday morning forcing the evacuation of several thousand homes.

Already there are reports of homes and structures destroyed as the fire rages in or near a number of populated areas. Late last night, power was cut off to upwards of 200,000 people as the fire crossed utility lines. And as of early this morning, the fire was reportedly advancing toward Ventura with 500 firefighters on the scene trying to beat the blaze back. Thankfully, as of yet, there are no reports of injury or loss of life.

Climate conditions on the ground have been very conducive to out-of-season wildfires. During the past month, temperatures across the region have trended between 2 and 4 degrees Celsius above average. Southern California is settling into drought. And over the past day, a strong high pressure system gathering to the north helped to send 40-60 mph Santa Ana winds rocketing over the hills and valleys around Los Angeles.

(Powerful high pressure ridge north of California sent strong Santa Ana winds over a region of California experiencing a warmer than normal fall and falling into drought. Image source: Earth Nullschool.)

Due to human-forced climate change and a related warming of the U.S. Southwest, the fire season for California now never really ends. Global temperatures have increased by 1.1 to 1.2 degrees Celsius since pre-industrial times, and climate zones are moving north. Both warmer temperatures and more extreme ranges of precipitation due to climate change aid wildfires in the west — first by allowing for rapid growth of vegetation during more intense wet periods and second by drying out these growths more swiftly as the climate regime switches to dry.

Since the 1980s, the number of large wildfires out west has quadrupled. But if fossil fuel burning continues, warming will also continue and the already difficult conditions we see will further worsen.

We are entering a time when a region of the west from California all the way north to Alaska and Alberta are starting to see wildfires capable of threatening cities with increasing frequency. If we are to dampen this trend, we need a change to less harmful energy sources and fast.

Gigantic Iceberg Disintegrates as Concern Grows Over Glacier Stability, Sea Level Rise

The stability of a key Antarctic glacier appears to have taken a turn for the worse as a large iceberg that broke off during September has swiftly shattered. Meanwhile, scientists are concerned that the rate of sea level rise could further accelerate in a world forced to rapidly warm by human fossil fuel burning.

(Iceberg drifting away from the Pine Island Glacier rapidly shatters. Image source: European Space Agency.)

This week, a large iceberg that recently calved from West Antarctica’s Pine Island Glacier rapidly and unexpectedly disintegrated as it drifted away from the frozen continent. The iceberg, which covers 103 square miles, was predicted to drift out into the Southern Ocean before breaking up. But just a little more than two months after calving in September, the massive chunk of ice is already falling apart.

The break-off and disintegration of this large berg has caused Pine Island Glacier’s ice front to significantly retreat. From 1947 up until about 2015, the glacier’s leading edge had remained relatively stable despite significant thinning as warmer water began to cut beneath it. But since 2015, this key West Antarctic glacier has begun to rapidly withdraw. And it now dumps 45 billion tons of ice into the world ocean each year.

(Glaciers like Pine Island balance on a geological razor’s edge. Because they sit on a reverse slope, it only takes a relatively moderate amount of ocean warming to precipitate a rapid collapse. These collapses have happened numerous times in the past when the Earth warmed. Now, human-forced climate change is driving a similar process that is threatening the world’s coastal cities. Image source: Antarctic Glaciers.)

The present rate of melt is enough to raise sea levels by around 1 millimeter per year. That’s not too alarming. But there’s concern that Pine Island Glacier will speed up, dump more ice into the ocean and lift seas by a faster and faster rate.

Pine Island Glacier and its sister glacier Thwaites together contain enough water to raise seas by around 3-7 feet. The glacier sits on a reverse slope that allows more water to flood inland, exposing higher and less stable ice cliffs as the glacier melts inland. If the glacier melts too far back and the ice cliffs grow too high, they could rapidly collapse — spilling a very large volume of ice into the ocean over a rather brief period of time. As a result, scientists are very concerned that Pine Island could swiftly destabilize and push the world’s oceans significantly higher during the coming years and decades.

No one is presently predicting an immediate catastrophe coming from the melt of glaciers like Pine Island. However, though seemingly stable and slow moving, glacial stability can change quite rapidly. Already, sea level rise due to melt from places like Greenland and Antarctica is threatening many low-lying communities and nations around the world. So the issue is one of present and growing crisis. And there is very real risk that the next few decades could see considerable further acceleration of Antarctica’s glaciers as a result of human-forced warming due to fossil fuel burning.

Dr Robert Larter, a marine geophysicist at British Antarctic Survey, who has researched Pine Island Glacier in his work with the Alfred Wegener Institute, recently noted to Phys.org:

“If the ice shelf continues to thin and the ice front continues to retreat, its buttressing effect on PIG will diminish, which is likely to lead to further dynamic thinning and retreat of the glacier. PIG already makes the largest contribution to  of any single Antarctic glacier and the fact that its bed increases in depth upstream for more than 200 km means there is the possibility of runway retreat that would result in an even bigger contribution to sea level.”

From Record Floods to Drought in Three Months: Unusually Hot, Dry Conditions Blanket South

Back during late August of 2017, Hurricane Harvey dumped as much as 60.48 inches of rain over southeast Texas. Harvey was the wettest tropical cyclone on record ever to strike the U.S. — burying Houston and the surrounding region under multiple feet of water, resulting in the loss of 91 souls, and inflicting more than 198 billion dollars in damages.

Harvey was the costliest natural disaster ever to strike the U.S. Its tropical rains were the heaviest ever seen since we started keeping a record. But strangely, almost inexplicably, just a little more than three months later, the region of southeast Texas is now facing moderate drought conditions.

(Just three months after Harvey’s record rains, Southeast Texas is experiencing drought. No, this is not quite normal despite a mild La Nina exerting a drying influence. Image source: U.S. Drought Monitor. Hat tip to Eric Holthaus.)

How did this happen? How did so much water disappear so soon? How could an instance of one of the most severe floods due to rainfall the U.S. has ever experienced turn so hard back to drought in so short a time?

In a sentence — climate change appears to be amplifying a natural switch to warmer, drier weather conditions associated with La Nina.

Climate change, by adding heat to the Earth’s atmosphere and oceans fundamentally changes the flow of moisture between the air, the ocean and the land. It increases the intensity of both evaporation and precipitation. But this increase isn’t even. It is more likely to come about in extreme events. In other words, climate change increases the likelihood of both more extreme drought and more extreme rainfall.

Of course, climate change does not exist in a vacuum. Base weather and climate conditions influence climate change’s impact. At present, with La Nina emerging in the Pacific, the tendency for the southern U.S. would be to experience warmer and drier conditions. But in a normal climate, these conditions would tend to be milder. In the present climate — warmed up by fossil fuel burning — the tendency is, moreso, to turn toward an extreme. In this case, an extreme on the hot and dry end of the climate spectrum.

For the region of Southeast Texas flooded so recently by Harvey’s record rains, it means that a turn from far too wet to rather too dry took just a little more than 3 months.

(Both temperature and moisture took a very hard turn over the past 30 days. Such extremely warm and dry conditions increase the likelihood of flash drought. A climate feature that has become far more frequent as the Earth has warmed. Image source: NOAA.)

South Texas, however, is just one pin in the map of a larger trend toward drought that is now blanketing the South. Over the past month, precipitation levels were less than 50 percent of normal amounts in most locations with a broad region over the south and west experiencing less than 10 percent of the normal allotment of moisture. Meanwhile, 90-day precipitation averages are also much lower than normal across the South.

Precipitation is a primary factor determining drought. But temperature can mitigate or worsen drought conditions. Higher temperatures cause swifter evaporation — driving moisture out of soils at a faster rate. And average temperatures across the south have been quite warm recently. With one month averages ranging from 1 C above normal over most of the south to a whopping 8 C above normal over parts of New Mexico. As with lower than normal precipitation, higher than normal temperatures have also extended into the past 90 day period across most of the South.

 

(Moderate drought conditions are widespread as severe to extreme drought is starting to crop up in the South-Central U.S. With La Nina likely to continue through winter and with global temperatures in the range of 1.1 to 1.2 C above pre-industrial averages, there is risk that conditions will intensify. Image source: U.S. Drought Monitor.)

The upshot is that moderate drought is taking hold, not just in southeast Texas, but across the southwest, the southeast, and south-central U.S. Severe to extreme drought has also already blossomed from northern Texas and Louisiana through Oklahoma, Arkansas and Missouri. This is relatively early to see such a sharp turn, especially considering the fact that La Nina conditions have only lasted for a short while and have, so far, been rather mild on the scale of that particular climate event.

Furthermore, like Texas, many of these drying regions experienced extreme rainfall events during spring and summer. Such events, however, were not enough to stave off a hard shift to drought in a world in which human-caused climate change is now driving both droughts and more extreme rainfall events to rising intensity.

(Predicted temperature and precipitation variance from normal over next three months. Climate change is likely to enhance this variability related feature. Image source: NOAA.)

With La Nina likely to remain in place throughout winter, the typical climate tendency would be for continued above average temperatures across the south and continued below average rainfall for the same region. Present human-caused global warming through fossil fuel burning in the range of 1.1 to 1.2 C above pre-industrial averages will tend to continue to amplify this warm, dry end of the natural variability cycle (for the southern U.S.).

In other words, there is not insignificant risk that the hard turn away from record wet conditions in the South will continue and that severe to very severe drought conditions will tend to spring up and expand.

Tesla Model 3 Production More than Doubled During November

Hands down, no other electrical vehicle company possesses the charging infrastructure, the high quality electrical vehicles, and the production infrastructure that’s now in Tesla’s hands. This system synergy provides unparalleled value to Tesla customers. Enabling them to use and improve their electrical vehicles with far greater ease than offerings from other automakers.

So when one reads about rising sales of the Chevy Bolt or how Volkswagen plans to sell 100,000 EVs per year by 2020 (Tesla sells that many now, in 2017), one should realize that both of these companies, though presently producing or planning to produce high-quality EVs, are behind in a race to catch Tesla. The Bolt, which sells for around 36,000 dollars hasn’t even yet caught up with the Tesla Model S — which costs more than twice as much. And Volkswagen is still waiting for its signature EV brands to be built over the next two years.

(Tesla deposits are an indicator of customer interest. Model 3 has been a primary driver of deposit increases since openings for reservations began in Q1 of 2016. Image source: Bloomberg.)

Struggles by Tesla to hit a rapid Model 3 production ramp, however, have caused some to question whether the revolutionary EV manufacturer and renewable energy company would hold on to that lead. Whether the delay would allow others to start to catch up. And of course some of this conjecture was puffed up by traditional Tesla bears and opponents — grasping at any bad news to spin against a rising green energy giant.

To be very clear, Tesla is at least 1-2 years ahead of the competition. So a month or two or three delay for the Model 3 production ramp — a vehicle which more than half a million customers have reserved — is not going to knock it out of its present leadership status. Longer term problems — lasting for more than 6 months — would be more telling, especially if reservation holders began to drift away. But Tesla’s present advantage is so significant at this time that the production fail on the Model 3 would have to be pretty monumental to provide any serious opening for the competition.

(Model 3 starting to break out of the pack. The vehicle is now the #21 best selling EV for all of 2017 and probably #11-12 for November. If the production ramp continues, the car will easily break the top 10 in December and probably become the best-selling EV in the U.S. by January or February. Image source: Inside EVs.)

To this point, according to reports from Inside EVs, Tesla produced and sold an additional 345 Model 3s during the month of November. This number is up 200 from the estimated 145 produced and sold during October. In total, Inside EVs estimates that 712 Model 3s had been sold by end of November.

Number sold is not number produced. So if Inside EVs estimates are correct, then Tesla has likely built over 800 Model 3s so far. And present trends make it likely that Tesla will complete between 1300 and 3000 of these revolutionary new vehicles by year-end. If this is ultimately the case, then the Model 3 production ramp is 2-3 months behind schedule. Disappointing to the hundreds of thousands waiting to get their hands on a Model 3, for sure. But not a crisis set to break the back of Tesla — as some have implied.

Hot Blob off Southeast Australia Fuels Life-Threatening Rain Bomb Event

Hot Blobs. These pools of severe warmth at the ocean surface have, during recent years, fueled all kinds of climate change related extreme weather ranging from droughts to floods to record hurricanes.

(Hot blob southeast of Australia features ocean temperatures as high as 8 F [4.5 C] above average. This is an extreme climate and severe weather-triggering feature related to climate change. One that has also been associated with strong, persistent atmospheric ridges and related high pressure systems. Image source: Earth Nullschool.)

The blobs themselves often form under persistent and strong high pressure systems which lock-in both heat and high rates of evaporation. These highs, sometimes called resilient ridges, are thought by a number of experts to be an upshot of changes to both atmospheric circulation and energy balance as a result of the Earth warming. They are an example of the kinds of extreme climate and related severe weather triggering outliers you would tend to expect in a warming world. A new kind of weather phenomena producing new effects.

Today, sea surface temperatures between Australia and New Zealand are ranging as high as 8 F (4.5 C) above average. A very significant warm temperature departure for this area of ocean. One that well meets the qualification for the term ‘hot blob.’ The large blocking high associated with the blob has, for some time now, been circulating very high volumes of moisture evaporating off these much warmer than normal waters over Eastern Australia. This moisture loading provides fuel for powerful storms in the form of both more explosive atmospheric lift and higher rainfall potential.

(Ridge-tough dipole triggers extreme weather in region prepped by moisture venting off an ocean hot blob. Image source: Earth Nullschool.)

All that heat and moisture bleeding off the hot blob just needed a catalyst to produce the kind of climate change related event I’ve been calling a ‘rain bomb.’ And, unfortunately for Southeast Australia, just this kind of catalyst in the form of a sharp facing trough in the Jet Stream and related upper level low forming over South Australia is on the way.

From today through late Friday, this low will generate added atmospheric energy that will produce very severe thunderstorms over Southeast Australia. Ones capable of generating extreme rainfall amounts in excess of 2 inches per hour over certain locations. With total rainfall amounts hitting between 4 inches (100 mm) and 12 inches (300 mm) between now and late Friday.

(Predicted extreme rainfall event is being fueled by very warm sea surface temperatures to the east.)

The storm system will also generate strong winds, lightning, and tidal flooding for some locales.

This is a dangerous event risking loss of property and life with a number of climate change related factors involved. Those in the areas affected should stay tuned to local weather (BOM) and government emergency management for storm and response information.

The Global Smack-down Against the Infernal Combustion Engine Achieves Full Charge

As the climate-wrecking fossil fuel age was climbing to dominance in 1943, Winston Churchill perhaps made the most famously telling Freudian slip of all time. In an attempt to laud the transition from the horse and buggy to the fossil-fuel driven car, he said to an audience at Harvard:

“Man has parted company with his trusty friend the horse and has sailed into the azure with the eagles, eagles being represented by the infernal combustion engine–er er, internal combustion engine. [loud laughter] Internal combustion engine! Engine!”

And as people from the Arctic to the Maldives to Bangladesh to the U.S. territory of Puerto Rico can now attest, the effects of the gasses produced by internal combustion have indeed started to become quite infernal as the leading edge of climate change related disasters begins to take hold.

(The LA auto show this week was dominated by new electrical vehicles.)

But at the same time that seas are rising and the weather is worsening, there is renewed hope that all this infernal combustion and related climate wrecking carbon dioxide spewing into the atmosphere may start to taper off. For if the age of unsustainable fossil fuels was heralded by an infernal engine, then the age of sustainability itself is being heralded by blessed batteries and the cars they power.

UBS — 1 in 6 New Cars to be Electric by 2025

For the electrical transition is happening now. And it’s charging up as we speak.

According to a recent report by UBS, the number of affordable, desirable electrical vehicles will vastly expand between now and 2020. Multiple vehicles that are competitive with, if not matching the performance of, Tesla’s Model 3 will be available by that time. These models will continue to proliferate through 2025.

(UBS estimates rapid increases in EV market share. This is bad news for fossil fuels and good news for sustainability.)

At the same time, prices for both batteries and vehicles are expected to fall. Total cost of ownership for electrical vehicles is already less than a comparable fossil fuel based car for a number of models. This is due to lower fuel and maintenance costs. However, overall total cost of ownership is expected to be less on average than fossil fuel cars by the early 2020s. Meanwhile, base price for EVs is expected to out-compete that of fossil fuel based cars by 2025 even as EVs are expected to consistently outperform ICE vehicles by that time.

As a result, UBS expects that between 6 and 25 percent of all new cars will be electric by 2025 with the average between these two predicted ranges hitting 16 percent or 1 in 6 of all new cars sold.

Volkswagen Invests More than $12 Billion in EVs

Tesla, presently the global EV market leader, is today’s company to beat. And Volkswagen, recently stung by an emissions scandal, appears to be stepping up to the plate as a serious challenger.

The company, this month, decided to invest 12 billion dollars to build as many as 40 electrical vehicle models in China. A market that by itself may support as many as 6-9 million EV sales per year by 2025. Volkswagen, in total, aims to sell 1.5 million electrical vehicles per year at that time.

(Volkswagen electrical car, SUV and Hippie Van spotted in California on November 27th. Image source: Clean Technica.)

Already, the company is developing multiple high-quality models to include an electric version of its iconic hippie bus, an electric car based on traditional Volkswagen styling, and a new SUV crossover called the CROZZ. All are expected to have a 200+ mile electric range and feature better performance than their fossil fuel counterparts.

Movement Toward Electrification Across Entire Industry

But it’s not just Volkswagen that appears ready to move aggressively toward electrification, pretty much every major automaker is adding new EVs between now and 2022 — with a number focused on total or near total electrification (see Jaguar video at top of post).

To name just a few, GM plans 20 new electrical models over the next six years, Ford plans 13 by 2020, and both Daimler and Renault plan to have 8 BEVs on the road by 2022. New entrants like BYD and Tata are also advancing electrical vehicles in their home markets of India and China. And the above-mentioned Jaguar expects all its new vehicles to have electric or hybrid electric drive trains by 2020.

Tesla Still Leading the Charge, But Will that Last?

Though numerous factors have driven the industry toward electrification to include falling battery costs, concerns about mass devastation from human-caused climate change, and drives by cities like Paris and nations like China to clean up air quality, it was Tesla, primarily, that proved to the world that EVs could be mass produced at market-setting quality and performance.

Tesla advances continue today with news reports indicating that the Model 3’s performance beats pretty much all of the BMW 3 series internal combustion engine cars hands down. And reviewers over at Motor Trend have gone so far as to call the Model 3 a BMW 3 series killer.

Meanwhile, indications are that production bottle necks may be starting to clear for the market-setting Model 3. Panasonic recently announced that battery production for the vehicle is about to speed up even as the company introduced reservation options for non employees this past week. If this is the case, Tesla is in the process of securing at least a 1-2 year jump on most major automakers.

(The new Tesla Roadster. Image source: Tesla.)

Tesla has also not let its various aspirational goals slip. Its offering of a 500 mile range long-haul truck by 2020 at $180,000 is yet another trend-setter. And the new Tesla Roadster with a 250 mile top speed, a 600 mile range, and featuring hyper-fast charging will basically far outperform even the top fossil fueled vehicles in pretty much every metric.

As the race between Tesla and the rest of the auto industry to produce the next trend-setting EV ramps up, it looks like the main loser will be that old pollution-belching infernal combustion engine. Good riddance.

54 Fahrenheit Above Average: Extreme Warming Event For Greenland, Baffin Bay Underway

At the mouth of Baffin Bay just off the West Coast of Greenland today hurricane force wind gusts are blowing in from the south.

This roaring invasion of warm air originates from the Central Atlantic along a latitude line south of the Azores. It climbs hundreds of miles north to where it is intensified between a grinding 975 mb low off Labrador and a massive 1042 mb high squatting over Central Greenland. Temperatures in this warm air mass range from near 50 degrees (F) over Southwestern Greenland to around 40 degrees (F) over the mouth of Baffin Bay. Or between 9 and 36 degrees (F) above normal for this time of year.

(Hurricane force wind gusts are driving a wedge of above freezing air into Baffin Bay and over Western Greenland at a time when these regions should be seeing well below freezing conditions. Image source: Earth Nullschool.)

This warm wind driven air mass is expected to move north over the next 24 to 48 hours. It will steadily blanket both glaciers and areas typically covered with sea ice. And as it does so, it will push temperatures above freezing for large sections of both Baffin Bay and Western Greenland with above 32 F readings progressing as far as the Petermann Glacier.

What this means is that temperatures will likely hit record ranges of up to 54 degrees Fahrenheit above average in some locations near the far northern extent of this expected warm air invasion. Overall, Greenland itself is expected to see 15 degree (F) above average readings for the entire island. This will generate brief surface melt conditions for parts of Greenland during late November.

(Large region of 20 to 30 C, or 36 to 54 F, above average temperatures is predicted to blanket Greenland and the Canadian Archipelago after moving north through Baffin Bay over the next two days. Image source: Global and Regional Climate Anomalies.)

Strong warm air invasions of the Arctic at this time of year are a signal coming from human-forced climate change. As the northern pole darkens with winter, a global warming related phenomena called polar amplification ramps up. In addition, during recent years, we’ve seen warm air slots tend to develop beneath strong ridging features in the upper level Jet Stream. This year, the warm air slots have tended to form over the Bering Sea along the Pacific side of the Arctic and progress northward into the Chukchi. This has resulted in a large zone of ice free waters for a typically frozen region between Alaska and Siberia as warm winds and storm force waves have continuously beat the ice back.

The present warm air invasion for Greenland may be a signal that a similar warm air slot is attempting to develop over Baffin Bay going forward. Or it may be a fluke in the overall pattern. Watch this space.

UPDATE 11/29/2017: As predicted, temperatures over the Petermann Glacier hit above freezing at around 2200 UTC yesterday. According to climate reanalysis, temperatures for the region are ranging between 50-54 F above average in present model estimates for 11/29. In other words, the warm air invasion progressed as expected and resulted in above freezing temperatures for brief periods across Western and Northern Greenland.

Overall temperatures for Greenland are presently 15.5 F (8.6 C) above average in the models while the Arctic as a whole is 9.9 F (5.5 C) above average.

Just One More Reason Why Fossil Fuels Suck Tailpipe — The Cost of Wind and Solar is Now Lower Than Pretty Much Everything Else

During October, in Australia, something rather strange and hopeful happened. Grid prices for electricity rose. Power customers, fed up with this, en masse decided to purchase 100 megawatts of rooftop solar in a single month.

How and why did this come to pass?

Conservative allies of fossil fuel based utilities are currently in control of the Australian federal government. And they have been working to provide captive grid-tied energy consumers for their political backers — polluting power system owners. Because these systems are more expensive than their renewable energy counterparts, the price of electricity went up.

The Australian public, who generally supports renewables and who likes to pay less for electricity, wouldn’t have any of it. They didn’t like being forced to purchase more expensive, polluting energy. So more than 15,000 of them decided to tell fossil fuel backers to go suck tailpipe and went on ahead and bought solar energy directly.

(Guess what? That green glass you see on the school in this image comes from hundreds of solar panels. Solar is versatile and increasingly inexpensive. You can put it on rooftops, building sides, car roofs, fuel station overheads, build it in traditional utility arrays, construct it on co-generating farms, or float it on reservoir surfaces. Image source: Inhabitat and EPFL.)

This choice, enabled by falling renewable energy prices, is one that people around the world will be more and more able to make as time moves forward. And it’s the case even in instances where national governments of western democracies are heavily influenced by fossil fuel special interests — as is presently the case in Australia. The primary reason is that when conservative governments support fossil fuels and nuclear over renewables, power prices to society rise.

The cost of both wind and solar energy are now less than every traditional power source even in more mature markets like the United States. In this major market, according to Lazard, the levelized price of nuclear is 14.8 cents per kWh, coal is 10.2 cents per kWh, gas is 6 cents per kWh, solar is 5 cents per kWh, and wind is 4.5 cents per kWh. That’s right. Renewables are about 1/3 the price of nuclear, half that of coal, and 10-20 percent less than gas in the U.S.

 

(The levelized cost of wind and solar energy keeps falling. This is making continued fossil fuel development an expensive and untenable prospect. Image source: Lazard.)

But in places like Australia and in the developing world, this price difference is even greater. In the developing world, there are less legacy fossil fuel power systems — which makes it a no-brainer just to go ahead and build less expensive renewables. And islands like Australia traditionally suffer from higher import costs for fossil fuels and clunky or inefficient fossil fuel energy system components.

Levelized cost is a way of measuring total life-cycle costs. It includes such costs as fuel, transmission and construction. Because renewables do not require fuel and because they are based on technologies that benefit from both advancement and economies of scale, they are able to continuously increase efficiency and reduce cost over time. Fossil fuel based power systems are mated to very inefficient combustion and to mining and extraction of fuels that grow more scarce over time. As such, the power systems they are based on tend to have difficulty reducing costs  and are subject to market shocks and scarcity of feedstocks.

These simple economic facts put the political backers of fossil fuels at a disadvantage on the issue of base economics. But these direct cost related factors don’t even begin to count in the terrible external costs of fossil fuels ranging from ramping damages due to climate change and direct health impacts by adding toxic particles to the air and water. As such, fossil fuels are both economically and morally untenable. But such simple and easy to understand facts haven’t stopped republicans like Trump in the U.S. and LNP members like Turnbull in Australia from trying to ram these harmful and expensive energy sources down the throat of an increasingly outraged public.

From Ice Apocalypse to Mega-Thunderstorms, Continuing to Burn Fossil Fuels Makes the World Scary as all Hell

So I’ve got to say I feel for Eric Holthaus.

Here’s a smart guy. Probably a few years younger than me. A meteorologist by degree and a climate journalist by trade. A guy with two kids that, as is clear from his twitter comments, mean all the world to him. And he’s finally gotten to that point in his study of climate change where he’s thrown his hands up and said — this stuff scares the crap out of me, can we please all just do something about it?

(The calving front of the Pine Island Glacier as seen by a NASA DC-8 aircraft. Image source: Commons.)

For him, as with any of us, the point of existential realization can come through overexposure to a wide range of worsening climate problems. Declining ocean health, rising extreme weather, how much faster we are warming the world up than during the worst hothouse extinction, can all weigh heavily on the heart and mind of any compassionate, feeling person who takes these subjects seriously enough to actually read the science. For Eric, the big deal, and it is a very, very big deal, was sea level rise.

Ice Apocalypse

Yesterday, Eric penned this seminal article on the issue of ice cliff stability as explored by glacier scientist Robert DeConto entitled Ice Apocalypse.

Ice cliff stability is a pretty technical term. One that may make the eyes of your typical reader gloss over. But when we consider that the glaciers of Greenland and Antarctica can be upwards of two miles high, then the question of whether or not the cliffs of those great ice mountains are stable may start to generate a flicker of warning. May conjure up a phantom of the titanic roar set off when such ice giants tumble away into the sea as has happened throughout the deep history of Earth whenever the world warmed up by a certain amount.

When I think of the words ice cliff stability, my mind’s eye pictures a vast wall of numbing white-blue stretching hundreds of feet high. It expands both left and right as far as I can see. And it looms over an endless warming ocean. Waiting for a colossal fall if just that right amount of extra heat is applied.

Ice is fragile. It’s not like stone. It doesn’t flex much. It doesn’t give much. And even minor stresses are enough to make it shatter. We see this with ice cubes in a cup of water at home. Put an ice cube into relatively warmer water, and that little 1×2 inch block will snap and crack. Now just compound that fragility. Set it on the massive scale of a mile-high glacier. Not too hard to image what can happen.

(2012 filming of massive calving event at Jakobshavn Glacier.)

It’s happened already at Jakobshavn Glacier in Greenland. The ocean warmed. The ice shelf protecting the glacier dissolved. And the front of the gigantic glacier fell like great, enormous, white dominoes. We’ve seen it happening in films like Chasing Ice. And we’ve struggled to grasp the enormous scale of it.

Our burning of fossil fuels did this.

Jakobshavn is, even now, contributing to a more rapid rate of global sea level rise. But the amount of ice held back by Jakobshavn is small when compared to the vast volumes kept in check by the Pine Island and Thwaites Glaciers of West Antarctica. What Robert DeConto did, and what has apparently scared Eric Holthaus so much, was apply a computer model based on observations of Jakobshavn ice sheet collapse to these larger Antarctic ice masses.

The DeConto study unearthed results that, indeed, looked apocalyptic. From Grist:

A wholesale collapse of Pine Island and Thwaites would set off a catastrophe. Giant icebergs would stream away from Antarctica like a parade of frozen soldiers. All over the world, high tides would creep higher, slowly burying every shoreline on the planet, flooding coastal cities and creating hundreds of millions of climate refugees.

All this could play out in a mere 20 to 50 years — much too quickly for humanity to adapt…

Instead of a three-foot increase in ocean levels by the end of the century, six feet was more likely, according to DeConto and Pollard’s findings. But if carbon emissions continue to track on something resembling a worst-case scenario, the full 11 feet of ice locked in West Antarctica might be freed up, their study showed.

The DeConto study is just one scientific exploration of what could happen in West Antarctica this Century. And, already, reassurances to a worried Eric Holthaus are forthcoming.

But the problem with the DeConto study, as with any other form of serious climate risk, is that there are plausible scenarios in which terrible catastrophic events are possible even if their degree of likelihood is still somewhat debatable. And reasonable precaution would dictate that even if there were just a 10-20 percent chance of DeConto like events coming to pass, we would do everything we could to avoid them. The risk of this scenario emerging, however, is probably a bit higher. As numerous studies have identified the potential for 6, 8, or even 12 feet of sea level rise by as early as 2100.

The Future of Mega-Thunderstorms Looks Grim if We Continue to Burn Fossil Fuels

Eric’s appeals to his Twitter friends related to his article were touching to me in that I feel like I go through similar shocks with each passing week. And what should be a time of national thanksgiving even as more than half of Puerto Rico’s population is still in the dark 63 days after the climate change amplified blow of Hurricane Maria is no exception.

For a model study recently produced by Nature Climate Change and explored by Bob Henson at Weather Underground has found that the rate of rainfall in large thunderstorm clusters could increase by 80 percent this Century if fossil fuel burning proceeds along a business as usual pathway.

To put this in context, an 80 percent increase in the amount of rain that fell in the Ellicott City Flood in Maryland last year would have produced nearly ten inches of rain in an hour and a half.

(The rainfall intensity in large thunderstorm clusters was found to be greatly enhanced under worst case fossil fuel burning scenarios [RCP 8.5] according to a recent Nature Study. Image source: NCAR, Nature, and Weather Underground.)

As with ice cliff instability, we find ourselves faced with another scientific term in the new study — mesoscale convective systems (MCS). And to translate this term we can simply say that MCSs are gigantic clusters of thunderstorms. The study found that rainfall amounts in the largest of thunderstorm complexes were greatly enhanced as warming proceeded along a business as usual track.

From the Study author’s statement to Weather Underground:

“These new simulations of future MCS rainfall are concerning, because they show very large increases in the amount of rain that a given MCS is likely to produce. The MCSs that we would today consider to be ‘extreme’ in terms of precipitation would become more commonplace in the future. There are also some regions that currently don’t see a lot of MCS activity that might start seeing some of these heavily raining MCSs in the future.”

These increases are on top of already elevated rates of rainfall intensity we presently see today in destructive events that our infrastructure and disaster planning is clearly not prepared for (as seen during Harvey). So as we take the time to give thanks for the great bounty that many of us still have, perhaps we should also take the time to think of the things we can do to keep safe what we have worked so hard for and care so much about and to do our best to help those who are less fortunate. Who have already fallen casualty to a time of troubles.

Global Electrical Vehicle Sales Grew by 63 Percent in the Third Quarter, But Model 3, Leaf, and Bolt Say You Ain’t Seen Nothing Yet

Tesla may still be the industry leader in global electrical vehicle sales. And though a very important player — primarily as a gadfly that’s helping to spur key renewable energy innovation through clean energy business models and competition — this story of a breakout in new energy production isn’t just about Tesla.

During July, August and September of 2017, according to Bloomberg, 287,000 electrical vehicles were sold worldwide. This is some pretty stunning growth equaling 63 percent more than during the same period of 2016 and 23 percent more than during April, May and June of 2017.

Electrical vehicle sales saw broad growth in all major markets. However, China experienced very rapid expansion of EV sales and was the primary driver of such a large jump with 160,000 electrical cars sold there in the 3rd quarter alone. Europe came in second with around 70,000 EV sales with North America following third with more than 55,000 EV sales. Since Bloomberg only tracked these major markets, total global EV sales were likely even higher, particularly when you consider that EV sales in places like Japan, India, other parts of Southeast Asia, and Australia are also on the rise.

China’s incentives aimed at cleaning up dirty air through EV purchases weighed strongly. In addition, pledges by various cities, states and nations to fully transition to electrical vehicles coupled with numerous policy incentives are helping to produce a ground swell of rising EV demand. However, EVs are also increasingly available, lower cost, and feature an expanding array of capabilities that are often competitive with or superior to their global warming producing fossil fuel competitors. And a number of new developments indicate that EV sales will continue to rapidly expand in the near term.

Signs the Model 3 Production Log Jam May Be Starting to Clear, Serious Competition on the Rise

During 2017, primarily on the strength of Model S and X sales, Tesla is the global sales leader for EVs at 73,227 cars sold through September. Chevy, runs a distant 7th with 36,963 EV sales through same period. While BYD, BMW, BAIC, Nissan and Toyota fall 2-6th in the global sales rankings thus far.

In the coming months, Tesla plans to be adding thousands of high-quality, lower cost Model 3s to its trend-setting volume. For 2017, the company is likely to hit near 100,000 sales in total. But if Tesla is able to achieve 5,000 Model 3 per week production by early 2018, that number could more than double in the follow-on year.

Presently, Tesla represents 10 percent of global electrical vehicle sales. And Bloomberg expects 1 million electrical vehicles to be sold globally during 2017. Yet during 2018, vehicles like the Leaf, the Model 3, and Chevy’s Bolt really have the potential to blow the lid off even these far-stronger numbers.

(The 2018 Nissan Leaf sold a pheonomenal 14,000 units during October of 2017. A record setting number of an all-electrical vehicle launch. Image source: Nissan.)

Nissan launched its longer range Leaf on October 1 of 2017 in Japan and Europe. And early reports indicate that sales of this model have just been going gangbusters. In total, 14,000 of the vehicles are reported to have moved in just one month — close to Tesla’s goal of hitting 20,000 per month by early 2018. The 2018 Leaf features a shorter range than the Model 3 (150 miles vs 210 for the base Model 3). But it also has a more attractive base price of 30,000 dollars (5,000 dollars lower than the base Model 3). And though not as zippy or sporty as the Model 3, the Leaf’s new design and 147 horsepower are nothing to shake a stick at. In total, for the same price, Leaf buyers are now getting a far more attractive and capable zero emissions vehicle. And though not in the same class as the Model 3, the Leaf is a serious competitor for those without the extra cash.

Hunger for lower cost EVs was also evident in Chevy’s sales of 2,871 Bolts in the U.S. during October. Though nowhere near the pheonomenal Leaf sales totals, the Bolt is giving Tesla a serious run for its money on its home turf in the U.S. And the high quality, 238 mile range Bolt is certainly a competitor of note. Priced about the same as the Model 3’s base vehicle at around 36,000 dollars, the Bolt is unable to compete on performance in any measure other than range. And its economy styling is certainly less appealing. However, the Bolt is nonetheless capable of capturing serious market share. Probably at least in the range of 30,000 to 50,000 annual sales.

With 500,000 pre-orders, the lower cost, longer range EV market still appears to be the Model 3’s to lose. And with a production ramp struggling to reach 440 vehicles by end October, Tesla looked like it was in a bit of a bind as competitors circled in. Yet some clouds appear to be readying to clear for Tesla as lots swell with Model 3s and the company opens up Model 3 orders to regular reservation holders. An indicator that production may finally be starting to ramp.

Understanding the Context — Sooner or Later, Model 3 Ramp is Imminent

In other words, the fact that Tesla is now transferring reservations into orders is an indicator that Tesla is now more confident in its ability to clear bottle necks and to rapidly ramp production. With a large number of employee pre-orders that need to be completed before it starts to meet regular customer orders, it appears that Tesla may be set to hit in excess of 1,000 Model 3s produced per week sooner than feared. However, we’ve seen hopeful signs of Tesla hitting an early production ramp disappointed before. So this news may just be another false signal.

What do you think? Will Tesla meet new competition coming from Chevy and Nissan by hitting a faster production ramp soon? Or are the Tesla woes of September and October here to stay for at least another few months? Please feel free to provide your take in the comments section below.

The Equatorial Pacific is Going Through its Variable Cool Phase, But 2017 is 94 Percent Likely to be the Second Hottest Year Ever Recorded

During late 2016, the Pacific Ocean started to cool off along its Equatorial region after experiencing one of the strongest warming events for that zone ever recorded. But despite this late cooling phase, the year ended up being the hottest ever recorded in the 137 year climate record — topping out at around 1.22 degrees Celsius above preindustrial temperatures. A longer term warming trend that has been directly driven by human burning of fossil fuels and related greenhouse gas emissions.

This year, the periodic Equatorial cooling known as La Nina is again taking place in the Pacific during fall following a very mild warming during winter and spring. But despite the appearance of a second such periodic cooling event, according to NASA 2017 is 94 percent likely to be the second warmest year ever recorded (see above).

October readings have come in and at 0.9 C above NASA  baseline (1.12 C above 1880s averages), temperatures are disturbingly high. The month is now the second hottest ever seen by modern humans. With only October of 2015 coming in warmer at 1.08 C above the 20th Century baseline (1.3 above 1880s).

(Heat transfer into the polar zones is increased during La Nina periods. This effect is enhanced by polar amplification related to human caused climate change. This week, very high relative temperature departures are expected for the Arctic. Image source: Climate Reanalyzer.)

Over the past two years, La Ninas (cooling Pacific) appear to have been at least partly off-set by very strong warming in the Arctic and Antarctic. Atmospheric circulation tends to transport more heat into the polar zones as the Pacific cools. This is due to the fact that temperature differential between Equator and poles during La Nina is less and the lower temperature differential causes the upper level winds to slow and meander. Coupled with polar amplification due to human-caused climate change, the result can be some pretty extreme temperature departures. This week is no exception as Arctic temperatures by Thursday through Saturday are expected to be between 4 and 5 degrees Celsius above average for the entire region above the 66 North parallel.

Such record warm temperatures do not occur in isolation. They help to drive extreme weather events such as severe droughts, rainfall, and powerful hurricanes. They are also accelerating sea level rise by melting glaciers even as both warming temperatures and related increasing ocean acidification contribute to dead zones, coral reef deaths and declining ocean health. Global temperature rise coupled with rising CO2 is therefore producing a major systemic crisis the world over.

Sudden Severe Flood Leaves 14 Dead in Athens, Forecasts Show Up to 15+ Additional Inches on the Way for Greece

Extreme drought. Extreme floods.

Unfortunately, with human-caused climate change, these kinds of devastating events have become far more frequent. With the Earth warming by around 1.1 to 1.2 C above pre-industrial averages, there are now four times as many instances of extreme weather than there were as recently as the 1970s.

What this means is that anywhere around the world now, the hammer of severe weather and related damages is four times more likely to fall than in the past. That the tempo of such events is now greatly increased. All thanks to continued fossil fuel burning, atmospheric CO2 levels that will average around 407 ppm over the coming months, the heat that these greenhouse gasses are continuing to add to the Earth’s climate system, and a failure to transition swiftly enough to more sustainable practices and zero carbon energy sources to prevent ramping damages.

Major Rain Event Strikes Athens — With More Severe Weather in the Forecast

Today, the major blow appears to have fallen on Greece. To the west of this country, over the Mediterranean, a cut off low is creating instability throughout the region. An intense, thick, moist warm air flow is moving in from the south. This warm and very water dense air is then colliding with a colder air mass to the north. Upper level instability is feeding powerful convection erupting in the atmosphere above Greece. And this convection is producing some mountainous thunderheads.

Last night, torrential downpours dropped 2-15 inches of rain over the outskirts of Athens. A biblical flood of water ripped through the region — rocketing vehicles down roads, prompting more than 600 calls for water rescues, killing 14 people, and leaving streets flooded or buried in mud while depositing cars into trees or on the tops of dwellings.

The rains stretched over a broad area from Greece to the Turkish coast — spurring declarations of emergency throughout the area. As with many of the increasingly fierce new disasters, it will take weeks or more to get a final tally of the total damages. But this event is probably not over.

Unfortunately, the cut-off low is expected to continue to circulate near this already flooded region for the next 3-4 days. Forecasts call for additional rainfall totals of up to 15 inches as the low churns and continues to generate outsized convection over an already hard-hit area.

Record Emissions: 41 Billion Tons of Heat-Trapping Carbon Dioxide Were Added to the Atmosphere This Year 

Over the past few years, something pretty amazing and hopeful happened. Global carbon emissions began to stabilize. This was caused, primarily, by stronger emissions reduction policies in China even as the rest of the world moved steadily away from coal burning and more and more toward adopting clean energy systems provided by the likes of wind, solar and electrical vehicles.

But during 2017, there appears to have been a return to rising emissions rates from both China and the rest of the world. As a result, a rather bad global climate situation is continuing to worsen.

China’s Swing Back to Coal and More Rapid Growth Result in Rising Emissions

As the major present emitter of carbon dioxide and a host to hundreds of hothouse gas spewing coal plants, any big move by China can also really move the global carbon emission total. We saw this in practice from 2013 to 2016 as China began to reign in rampant coal consumption and as global emissions levels subsequently responded.

(During recent years, global carbon emissions have plateaued. But during 2017, a new record high was reached on the back of a return to increased rates of coal burning in places like China. The peak year of fossil fuel burning and the year at which net negative carbon emissions occur are very important factors in determining future warming. And even the best case emissions scenarios will likely lead to 2 C or greater warming this Century. Impacts from 2 C warming will be very difficult to manage with a high likelihood that at least some widespread catastrophic impacts would occur. 3 C warming would be terrible — with very widespread harm and disruption. And it is unlikely that most nations would survive the impacts related to 4 to 6 C warming. Image source: University of East Anglia.)

This year, we see a bit of backsliding by this key energy and climate player due to a combined reduction in hydro based power supply and strong annual rates of economic growth.

Drought afflicting China has hit hydro-electrical power generation pretty hard. China presently possesses about 320 gigawatts of hydro power generation capacity. This is about 1/3 of its total coal generating capacity and compares to a relatively smaller wind and solar capacity of around 150 gigawatts. So any disruption to water flowing into hydro generators can have a big effect on coal use and related downstream carbon emissions.

China also rapidly added solar this year. But it was apparently not enough to offset the impact to hydro resources which increased demand for coal. In addition, China’s rapid projected growth rate of 6.8 percent in GDP also resulted in higher overall power demand — leading to more coal burning. Overall, China’s carbon emissions grew by 3.5 percent or around 350 million tons per year. This increase is well ahead of overall global carbon emissions growth in the range of 2 percent for 2017.

U.S. and E.U. Emissions Drop; India and Rest of World Sees Rise

Other factors included a slowing of U.S. carbon emissions reduction due to a degradation of helpful climate policies by the Trump Administration. Despite this deterioration, U.S. emissions fell by 0.4 percent or around 21 million tons per year. The European Union also saw continued if slow emissions reductions of around 7 million tons per year. Environmentalists have criticized mixed policies in places like Germany that continue to protect high-carbon coal burning. But the picture for the EU has, overall, been one of slow if steady progress. India-based emissions increased by a slower than expected rate of 50 million tons per year. Another somewhat disturbing feature in the new data shows that the rest of the world saw carbon emissions grow by 2.3 percent or about 305 million tons per year.

(Most energy and climate experts did not expect to see a potential peak in global carbon emissions until at least the early 2020s. However, 2013 to 2016’s plateau did provide a hopeful look at what was possible. In order to see an actual peak, the countries of the world will have to be far more aggressive about shutting down fossil fuel based energy sources and rapidly deploying renewables. Image source: The University of East Anglia.)

So even without the big bump in China’s emissions, the world, as a whole would have experienced some CO2 emissions growth. But this single country accounted for almost half of all carbon emissions growth around the world during 2017. And it is worth noting that even a relatively minor reduction in carbon emissions by China this year would have resulted in an extension of the global carbon emission plateau.

A Problem Caused by Fossil Fuel Burning

Where the problem of increasing carbon emissions is coming from is pretty obvious. According to reports, 41 billion tons of CO2 were emitted to the atmosphere during 2017 due to human activities. Of this amount, almost 90 percent came from fossil fuel burning — accounting for 36.8 billion tons of CO2 each year. This overall rate of emission is more than ten times faster than during the last hothouse extinction event to occur on Earth.

(Annual rates of atmospheric CO2 accumulation are now higher than 2 parts per million per year. The last time atmospheric CO2 levels were as high as they are now — around 407 parts per million — the oceans were between 25 and 75 feet higher than they are today. Image source: The University of East Anglia.)

The present increase is problematic in that it also makes it less likely that warming this Century will be limited to 1.5 or 2 C. The scientific community has often identified these as safer limits for warming. But we should be clear that no level of warming is entirely safe. That present warming in the range of 1.1 to 1.2 C above preindustrial levels is already causing harmful impacts like shifting climate zones, more instances of damaging, extreme weather, worsening wildfires, and ramping rates of sea level rise that are threatening islands and coastal cities. We should also be clear that present atmospheric greenhouse gas levels in the range of 407 ppm CO2 and 491 ppm CO2e imply a warming close to or above the 1.5 to 2 C threshold range by the end of this Century even if these levels were to merely remain stable.

An Increasingly Urgent Situation — But the Means of Lessening the Damage is at our Disposal

The urgency of the situation, therefore, cannot be understated. We are presently living in a time during which the safety of global civilization requires that we rapidly reduce to zero presently unprecedented annual levels of greenhouse gas emissions. And the first step to doing this is a swift as possible cessation of fossil fuel burning enabled by a transition to renewable energy.

It is worth noting that 2017’s rate of carbon emissions growth was less than the 3 percent annual rates experienced during the decade of the 2000s. Back then, less well developed renewable energy technology and very rapid economic growth in places like China resulted in far higher annual emissions gains than we see at present. So 2017’s gain may be a blip due to circumstances as combined wind, solar, and electrical vehicle advances begin to take hold of the larger energy and emissions trend. That said, challenges to rates of renewable energy adoption and related rates of carbon emissions reduction coming from right-wing governments like the Trump Administration should not be discounted. Failure to act by leaders in the U.S. and around the world or attempts to return to increasing rates of coal, oil, and gas burning are measures that will result in serious harm going forward.

We are thus at a moment of crisis when it comes to global emissions. We can continue to move forward on replacing fossil fuels with zero emitting energy sources. Or we can return to the very harmful increases in global carbon emissions of the past — at which point the damages we see from climate change will be rapidly enhanced.

Denial’s Grim Fruits — Actual Puerto Rico Death Toll Probably Near 500; May Climb to Over a Thousand

Massive disruption which results in cascading failure of basic services such as food, water transport and power. That’s the primary catastrophic risk coming from human forced climate change. And we are now in the process of multiplying the potential for such extreme events by continuing to burn fossil fuels and to dump carbon into the atmosphere.

Maria’s recent landfall in Puerto Rico and resulting unprecedented disruption can be seen as a microcosm of the kind of damage that might ultimately be inflicted upon a whole region or nation. And the various failed responses by the Trump Administration and related denial-based attitudes within the Republican Party do little to inspire confidence in the ability of at least one major party to effectively respond to a rising danger it pretends does not exist at all.

Excess Death Toll

Weather forecasters are often quick to point out that the most dangerous direct impact from a major hurricane comes from either storm surge or flooding rains. However, for days, weeks, and, in the case of Puerto Rico, months following a disaster, the major cause of loss of life is disruption of food, water, power supplies and a related increased risk of exposure to infectious diseases.

Due to a sluggish and lackadaisical response to the worst storm to strike Puerto Rico in 85 years by the Trump Administration, it appears now that hundreds of lives have been lost. According to reports from the New York Times, 472 more people died during September of 2017 following Maria’s strike than during September of 2016. Such an abnormally high monthly death rate is an outlier in statistics that epidemiologists call an excess death toll. And the primary likely cause was damage to infrastructure, power, food and water by Maria followed by an inadequate emergency response effort.

Many of the 3.4 million people still living in Puerto Rico have been forced to go without reliable access to water, food, and power for 54 days now. Trump Administration failure to mobilize a major effort to respond to the largest power outage and infrastructure disruption in U.S. history has been coupled with the allowance of vulture capitalist firms like Whitefish to prey on Puerto Rico by charging excess fees for power restoration.

Digging into these glaring failures a bit more, it took more than two weeks for Trump to mobilize 5,000 troops to send to Puerto Rico to assist in aid efforts. And Maria was a disaster that required a force ten times this large to be pre-positioned and then sent in immediately following the disaster, according to emergency planners. Vulture firm Whitefish has been reportedly charging 4 to five times what it is paying power installers on an hourly basis. An obvious level of price gouging that has caused the firm’s contract to be canceled. But not before this company of two permanent employees bungled a power line repair that again resulted in much of Puerto Rico falling into darkness.

Incompetent Governance

Whitefish’s most recent failure resulted in total power availability for Puerto Rico again dropping below 20 percent last week. With PREPA stepping in after Whitefish dropped the ball, the line has been repaired. Yet 52 percent of Puerto Ricans are still without power.

(Climate Change amplifies hurricane impacts. What this means is that as the world warms, hurricanes produce more damage. If this is the case, then governments are going to have to step up and act responsibly to prevent loss of life. Republicans and the Trump Administration have done exactly the opposite in Puerto Rico. Images source: Climate Signals.)

Lack of power itself can be deadly. Such a loss results in a critical shortage for medical equipment necessary to save people’s lives even as it removes key infrastructures like street lights and communications. Incubators, defibrillators, respirators, pulse monitors and a hundred other life saving devices all go dark when the lights go out. Furthermore, lack of clean water and ready access to food increases instances of infection. And damage to roads prevents access by emergency personnel to people falling into harm’s way.

Vulture Capitalism + Climate Change Denial = Failed Responses and Profiteering in the Face of Rising Disasters

This is why Maria’s blow has now become so hurtful. Why the Trump Administration’s neglect is so glaring. And a thousand or more people may have perished as a result. The role of the U.S. Government as the first responder to major disasters was sidelined. The sacred trust to Citizens of the United States violated. But, outrageously, such a lackadaisical, laissez faire attitude is not simply limited to Trump. It is an unfortunately endemic feature of today’s republican party. A party that is now doing its best to cut taxes for the rich while cutting medical coverage for 13 million Americans.

A party that has also done far, far more than its fair share to deny and prevent responses to the human caused climate change from fossil fuel emissions that made Maria far, far worse. For the storm emerged from warmer than normal oceans that helped to pump up its peak intensity. It was one of many storms made worse by climate change — for studies now indicate that at least 63 percent of all extreme weather events have now been pumped up in a warming atmosphere or over a warming ocean. And with just 1.2 C worth of warming achieved, the worse is still to come.

With the republican party both causing these disasters to worsen and ensuring that their damaging impacts are amplified by delayed responses, irresponsible choices for firms contracted to bring infrastructure back up and running, and overall malfeasance, it’s pretty clear that only a numb-skull would vote for such mouth-breathers. But here we are.
