NOAA’s 2017 Arctic Report Card Shows Transition Toward Not-Normal Polar Environment Continues

The Arctic shows no sign of returning to the reliably frozen region of recent past decades. — NOAA

Reading this [Arctic Report Card], I feel physically sick. I feel so anxious. I’m not sure how many more years or months I’m going to be able to work daily on climate change. — Eric Holthaus

*****

During 2017, the Arctic experienced much warmer than normal winter and fall temperatures. Meanwhile, according to NOAA’s 2017 Arctic Report Card, somewhat cool late spring and early summer temperatures did little to abate a larger ongoing warming trend.

NOAA notes:

The average surface air temperature for the year ending September 2017 is the 2nd warmest since 1900; however, cooler spring and summer temperatures contributed to a rebound in snow cover in the Eurasian Arctic, slower summer sea ice loss, and below-average melt extent for the Greenland ice sheet.

(NOAA’s Arctic Report Card shows a Polar environment experiencing serious and harmful changes.)

This warming trend was evidenced by continued systemic long term sea ice losses with NOAA stating that sea ice cover has continued to thin even as older, thicker ice comprised only 21 percent of Arctic Ocean coverage compared to 45 percent during 1985.  NOAA noted very slow Chukchi and Barents sea ice re-freeze during fall of 2017 — which was a feature of much warmer than typical sea surface temperatures during late August. Temperatures which ranged up to 4 C above average for this time of year and that created a kind of heat barrier to typical fall ice cover expansion.

Sea ice is a primary indicator of Arctic health. But losses over recent decades have been quite precipitious as indicated by the graph below:

Sea Ice Coverage Loss

NOAA also found evidence of ongoing increases in ocean productivity in the far north — which tends to be triggered by increasing temperature and rising ocean carbon uptake (also a driver of acidification).

Other observations of systemic warming came as permafrost temperatures hit record levels during 2016.  Decadal rates of permafrost warming as measured at Dead Horse along the North Slope of Alaska proceeded at a rate of 0.21 to 0.66 degrees Celsius every ten years.

(Changes in Arctic ground temperature [20 meter depth] at varying locations shows widespread movement toward permafrost thaw. Image source: NOAA.)

Tundra greening trends also continued over broad regions:

Long-term trends (1982-2016) show greening on the North Slope of Alaska, the southern Canadian tundra, and in the central Siberian tundra; tundra browning is found in western Alaska (Yukon-Kuskokwim Delta), the higher-Arctic Canadian Archipelago, and western Siberian tundra.

Rapid warming of the Arctic, loss of sea ice, permafrost thaw, greening tundra, changes in ocean productivity and other factors are all starting to seriously impact the people of the Arctic. Coastal towns have been forced to move inland due to erosion and sea level rise. And a number of communities have lost access to key food sources due to sea ice loss or migration of local species away from warming regions. Subsidence has generated harmful impacts to infrastructure. Meanwhile, the increased incidence of Arctic wildfires presents a rising hazard to Northern Communities:

High latitude fire regimes appear to be responding rapidly to environmental changes associated with a warming climate; although highly variable, area burned has increased over the past several decades in much of Boreal North America. Most acreage burned in high latitude systems occurs during sporadic periods when lightning ignitions coincide with warm and dry weather that cures vegetation and elevates fire danger. Under a range of climate change scenarios, analyses using multiple approaches project significant increases (up to four-fold) in area burned in high latitude ecosystems by the end of the 21st century.

Taken together this is tough news — a technical report written in the lingo of science but that, in broad brush, describes evidence of a world fundamentally changed. For those of us with sensitive hearts, it’s a rough thing to write about:

Overall, NOAA calls for increased efforts to adapt to climate change in the far north. In addition, the need for mitigating harms from climate change by speeding a transfer to renewable energy could help to preserve cryosystems and ecosystems that are now under increasingly severe threat.

Record Warmth Blankets Alberta

Extreme warmth associated with a powerful western high pressure ridge and conditions related to climate change has broken temperature records across Western Canada during recent days.

On December 9, the southern Alberta cities of Lethbridge and Grand Prairie saw temperatures rising to record highs of 14 C or 57 degrees Fahrenheit. Meanwhile, Calgary experienced 15.4 C temperatures (60 degrees F) — which shattered the previous record of 14.4 C that had stood for 127 years. Four other cities in southern Alberta also saw record warm temperatures on Saturday.

For context, temperatures for this region typically range between -1 to -13 C this time of year.

(The first 11 days of December show far above average temperatures for most of Western North America and the Arctic. Image source: Global and Regional Climate Anomalies.)

The primary feature driving such extreme temperatures is a power high pressure ridge that has been anchored in place during November and December. The ridge has been drawing warm air north and generating unusually warm weather for regions from the U.S. West through central and western Canada and on up into the Northwest Territories and Alaska.

Very slow reformation of sea ice in the Chukchi and Bering Seas is a likely contributing factor to the ridge. A physical feature associated with human-caused climate change. La Nina is likely also enabling the synoptic transfer of heat into both the Arctic and the North American West through a very pronounced Rossby type wave pattern in the Jet Stream. But present Arctic warmth in the range of 3-5 C above climatological averages is well beyond 20th Century norms during La Nina years. It is instead primarily an upshot of polar amplification — where human-forced warming due to greenhouse gas emissions generates more warming at the poles than in the lower latitudes. So climate change related factors are also influencing this overall warmer than normal pattern.

(Above freezing temperatures aren’t typical for Alberta this time of year. But the region was blanketed by 40-60 degree [F] highs on Saturday. That’s 9 to 27 degrees [F] above average. Image source: Earth Nullschool.)

As a result, places like Calgary haven’t received any snowfall so far this year during December. A situation that is likely to continue for at least the next five days as warmer than normal conditions are expected to persist.

December is typically a rather snowy month for Calgary — receiving 8 days of snow during a normal year. But this year isn’t really that normal and the climate, with global temperatures exceeding 1 C above 1880s averages, isn’t normal anymore either.

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.

The 6,000 firefighters now engaged in battling these blazes 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 790 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.

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.

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.

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.

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.

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.

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.

Climate Change Related Drought Bakes the Iberian Peninsula

“Suddenly what was once thought to be a problem confined to the third world has arrived in southern Europe.”Euronews.

*****

We’ve been taught that human-caused climate change through fossil fuel burning only affects poor people. That it only affects the third world. That if you’re rich, or if you live in places like the U.S. and Europe, you’re safe — or at least safer.

We’ve been misinformed.

Climate Change in Our Front Yard

Here, on this blog, again and again, we’ve been warning that climate change impacts EVERYONE. That no-one is really safe from either its direct or systemic impacts. From the subsistence farmer in Africa to the Wall Street hedge fund manager, the damage is ultimately equally bad.

The reason is that the worsening climate change related impacts of sea level rise, extreme weather, acidifying and anoxic oceans are ultimately so far reaching that you can’t call any place on Earth realistically safe from harm. And even if you do avoid the barrage of these varied impacts personally, the damage from rising levels of warming is eventually so deep and widespread that there is serious risk of collapse to the various systems civilization relies on to function — like water, power, transportation, and food supply.

(Despite popular misconception, the wealthier countries of the world are not immune to or even really very resilient to the impacts of climate change. We are seeing this start to bear out now in numerous places to include Southeastern Europe. Namely, the Iberian Peninsula where drought is severely impacting Portugal and Spain. Image source: Global Drought Monitor.)

Though the effects may well be milder at the present 1.2 C warming than they would be at 2 C, 3 C, 5 C or more, they are starting to hit now. And they are hitting indiscriminately across broad regions from Canada, to California, to New York City, to New Orleans, to Brazil, to Bangladesh, to Russia, to Puerto Rico, to India and China, and to more far-flung and wildly varied locations than we can list here. The systemic collapse of Puerto Rico due to a global warming amplified hurricane, can be seen as a relative microcosm to what’s in store for broader global civilization if we don’t get our act together in reducing carbon emissions zero and then net-negative , limiting future warming to more manageable levels, and hardening societies to warming related impacts as rapidly as possible.

Severe Drought in Spain and Portugal

This week, just one more story of catastrophic climate change related impacts focuses on the Iberian Peninsula in Europe. 2017 is presently Spain’s third driest year on record. Following an abnormally dry 4-year period, the situation is starting to get critical. The Douru River, which is basically the Spanish wine-growing region’s Mississippi, is 60 percent dry. Massive reservoirs like the Cuerda del pozo are empty. Hydroelectrical supplies have been cut by 58 percent. And wildfires and crop failures have run rampant with the worst grape harvest in decades leading to a global shortage of wine.

In Portugal, the driest October in 20 years has spurred a government campaign to conserve water — asking people to turn off the taps immediately rather than leave them running. In some places of the country, water is having to be shipped in by truck as local sources fail. The Prime Minister of the country is stating that a water miracle is needed to relieve drought conditions.

These impacts follow a deadly wildfire outbreak in October that killed 44 people and injured 71. One of the region’s worst on record that adds to the context of fires like the Fort McMurray Fire in Alberta and the recent Northern California wildfires that destroyed more than 10,000 buildings.

Rain in the Forecast, But Global Warming Will Bring Worsening Droughts to the Region

Human-caused global warming increases the likelihood of extreme drought by increasing the rate of both precipitation and evaporation. Because this effect is uneven, as the world warms, the prevalence tips toward the extremes. In other words, more of the rain we receive falls less frequently but in heavier events. In addition, rising temperatures enhance the onset and intensity of drought.

For Spain and Portugal, climate zones are moving north. This means that desert-like temperatures and conditions from across the Med in the Sahara are more frequently invading. A reality that most of Southern Europe will eventually face if the Earth continues to warm. That said, forecasts for this winter call for some relief in the form of increased precipitation. For Spain and Portugal, it couldn’t come too soon. But with conditions having been consistently drier than normal over recent years, it will take a very significant pattern change to alleviate presently severe conditions.

Extreme Warming at the Poles this Week — Arctic and Antarctic Temperatures to Rise to 20-30 C Above Average in Some Locations

Human-caused climate change via fossil fuel burning produces a number of stranger things. And some of the weirdest happen to occur in the polar regions of our world.

One of the foremost of these odd impacts is called polar amplification. Under polar amplification, the warming effects of elevated greenhouse gasses are concentrated at the poles. This is due to reduced reflectivity (albedo) from smaller snow and sea ice concentrations, due to the increased intensity of the greenhouse effect in colder and darker regions, and due to increased energy transfer from lower latitudes into upper latitudes due to weakening of the polar Jet Stream.

Over the next week, this kind of polar amplification is predicted to generate very extreme warm temperatures for both poles of our world.

(Warm winds blowing into the Arctic will produce far above average temperatures this week. Image source: Global and Regional Climate Anomalies.)

In the Arctic, temperatures in both Northern Greenland and on the Siberian side of the Arctic Ocean are predicted to hit ranges higher than 20 degrees Celsius above average (36 degrees Fahrenheit) with some readings over Northeastern Siberia striking near the 30 C above average mark by early next week (54 degrees F). This will produce near or above freezing temperatures over both Siberia and sections of the Arctic Ocean near or north of the 80 degree North Latitude line. Overall, temperatures are predicted to average as high as 4.4 C above average for the entire Arctic. A very considerable warm temperature departure consistent with the heightened levels of global warming the world has been experiencing during recent years.

In the Antarctic, where temperature variance should be moderating as austral spring shifts toward summer, the exact opposite is occurring. Very warm temperatures hitting more than 20 C above average are expected to sweep across East Antarctica this week and ultimately cross over to West Antarctica. Above freezing or near freezing temperatures in some coastal regions including coastal West Antarctica and over the Amery Ice Shelf in East Antarctica will accompany far warmer than normal, but still below freezing, temperatures inland.

(Even as the Arctic is predicted to heat up, the Antarctic is also expected to experience much warmer than normal conditions. Image source: Global and Regional Climate Anomalies.)

Overall temperatures for East Antarctic land masses will hit an amazing 7 C above average even as temperatures for West Antarctic land masses rise to 5.1 C above average for later this week.

Primary atmospheric drivers for these warming events are large synoptic warm wind patterns drawing above average temperatures into both the Arctic and Antarctic. In the Arctic, winds crossing hundreds of miles of warm Pacific Ocean in association with the back side of a high pressure system moving over the Bering Sea will draw these very warm temperatures northward. In the Antarctic, warm winds funneling southward from Australia will reinforce the influence of a strong high pressure dome over East Antarctica even as another strong synoptic warm wind pattern feeds into West Antarctica off the Pacific and Southern Oceans later in the week.

It’s very early for temperatures over parts of Antarctica to be pushing above freezing. And it’s rather late for such similar temperatures to be continuing to invade so far north into the Arctic. So much warmth will have an ongoing deleterious impact to both sea and land ice as well as snow cover. Contributing to the overall pattern of warming and melt we’ve seen for both Antarctica and the Arctic during recent years as global temperatures have risen into a range from 1 C to 1.2 C above 1880s averages.

Sandy-Like Situation Developing? Tropical System to Merge With Potential Record-Breaking Nor’Easter by Sunday.

It’s not yet predicted to be a so-called perfect storm. But a Sandy-like situation appears to be on tap for the U.S. Northeast this weekend. For the forecast weather coming down the pipe bears a distinctly odd combination of features similar to the climate change related hybrid hyperstorms we’ve seen during recent years. To be clear, the presently predicted hybrid storm is not expected to be as intensely ‘perfect’ as Sandy. But it could still be a record-breaker for parts of the Northeast with regards to October rainfall and minimum central pressure come Sunday.

Tropical System Predicted to Combine with a Nor’Easter

93 L isn’t even a tropical depression yet. But this stormy collection of clouds southeast of the Yucatan continues to gather and organize over warmer than normal waters. At this time, development into a tropical system appears more likely — with the National Hurricane Center predicting a 60 percent chance of storm development over the next 24 hours.

To the north, a very deep trough is poised to plunge down over the Eastern Seaboard of the United States. Another one of those high amplitude Jet Stream waves born of conditions related to a warming Arctic. And all across the storm’s projected path sea surface temperatures range between 1 and 4 degrees Celsius above the climatological average.

By Sunday, 93 L is predicted to be funneling into the southern section of this trough just east of Florida. Present model runs show the tropical storm transferring its warm energy northward into a low along the Arctic-originating frontal system over these warmer than normal waters — with potentially extreme results.

(Northern New England doesn’t have a record of a storm with pressures lower than 980 mb during late October. The present storm could intensify to pressures lower than 980 mb as it crosses over this region late Sunday — setting a new record. Image source: Tropical Tidbits.)

Forecasts are presently calling for one day rainfall amounts that could break records for New England. A swath from New Jersey through Eastern New York and western Maine could see between 2 and 8 inches of rainfall in a very short period. Meanwhile, atmospheric pressures could drop to near or below 980 mb as the storm moves north — a measure below 980 would be a new record for Southern New England in October (Sandy hit lower pressures during its Oct 29 New York landfall in 2012).

This is a climate change related movie that we’ve seen before. One that is, thankfully, predicted to be a bit less intense than Sandy this time. That said, those along the U.S. East Coast should keep a keen weather eye out as Arctic air moves over these warmer than normal waters and wraps in an energetic tropical system when the trough plunges south. Moist tropical air colliding with this Arctic mass over these warm, wet waters will create the potential to generate a powerful temperature and moisture dipole in a lifting atmosphere that could well cause this predicted storm to swiftly explode to record-shattering intensity.

Hundreds of Billions of Dollars in Damages, ‘Toasted, Roasted, and Grilled’ — That’s What Trump’s Refusal to Support the Paris Climate Agreement Gets Us

So far, in the past three months, we’ve had four major U.S. disasters whose impacts we can certainly say were made worse by human caused climate change.

The costs from these disasters to U.S. society and, in the end, to citizens and taxpayers is tremendous. Thousands of people have lost their homes. Irreplaceable lives were forever stripped from us. Many have lost access to work and livelihoods. And in the case of Puerto Rico, hundreds of thousands of people have been thrust back into what amounts to a modern rendition of the dark ages.

As a measure of money alone and leaving aside the untold human misery, hurricane Harvey may ultimately cost the U.S. $180 billion, Irma may cost the U.S. $65 billion, and Maria may ultimately cost the U.S. as much as $100 billion. Adding in the $85 billion dollar damage estimate for the devastating California wildfires which were also made worse by climate change, and the total cost to U.S. society from these four disasters alone may top $430 billion.

Sitting at 1 to 1.2 C warming and staring down the barrel of 2-4 C or greater warming this Century, we can definitely say that these kinds of disasters are going to get worse. That we need to be both aware and prepared. And that we need to do our best to limit future damages to more manageable levels by working as hard as we can to reduce the climate disaster enabling greenhouse gas emissions. The world agreed to such limits at Paris. And yet it is a mark of consequential irrationality amounting to massive and indiscriminate inflicted harm that the Trump Administration has forced us to withdraw from this noble and moral compact.

A basic fact that hasn’t been lost on Christine Lagarde, chief of the International Monetary Fund, who wrote today in The Guardian that if the world fails to take steps to reduce climate change, we will be ‘toasted, roasted, and grilled.’ Lagarde warned of a dark, dystopian future if major nations fail in their moral responsibility to address climate change — citing the fact that the Trump Administration in the U.S. has withdrawn from the Paris Climate Summit. A global commitment to more rapidly reduce greenhouse gasses that Nicaragua recently joined leaving the U.S. only accompanied by Syria as inauspicious non-signatories.

A federal U.S. policy blind to the impacts of climate change under Trump is far from immune to its slings and arrows, as we’ve found so tragically this summer and fall. And underlying this fact is that an unaffiliated Government Accounting Office (GAO) report from Trump’s own government recently found that climate change related extreme weather and other related damages have topped $350 billion over the past decade. A number likely to significantly increase once recent events are also tallied. A number that will be dwarfed by future events if fossil fuel burning related carbon emissions continue to hit the atmosphere at their geologically unprecedented rate of more than ten billion tons each year.

The report took two years to compile at the bipartisan requests of Susan Collins of Maine (R) and Maria Cantwell of Washington (D). Ms Cantwell noted to the New York Times that the report is:

“basically telling us that this is costing us a lot of money...We need to understand that as stewards of the taxpayer that climate is a fiscal issue, and the fact that it’s having this big a fiscal impact on our federal budget needs to be dealt with.”

The report identified wide-ranging climate change related impacts coming from hurricanes, wildfires, sea level rise and damages to crops. Impacts that do not discriminate between political affiliation or level of income. However, it is notable that the U.S. Southeast, a traditional republican stronghold, is one of the regions the report identifies as likely to experience the some of the most severe and damaging impacts related to climate change.

Failure to provide significant national and international policy to address climate change, in Trump, is not only a failure to recognize basic scientific fact. It is not only putting the U.S. in a less competitive position economically with regards to renewables. And it is not only making the U.S. more vulnerable to the powerful storms and severe weather events such failures contribute to. It is also a dramatic failure of basic fiscal responsibility that will have an equally dramatic and long-last impact on deficits, budgets, taxes and ultimately incomes for years and decades to come.

Another Historic Storm: Surreal Ophelia Strikes Ireland with Hurricane Force

“Ophelia is breaking new ground for a major hurricane. Typically those waters [are] much too cool for anything this strong. I really can’t believe I’m seeing a major just south of the Azores.” — National Hurricane Center scientist Eric Blake on Twitter.

*****

Warmer than normal ocean temperatures due to human-forced climate change are now enabling major hurricanes to threaten Northern Europe. A region that was traditionally considered primarily out of the range of past powerful Atlantic Ocean hurricanes under 20th Century climatology. One that, in a warmer world, is increasingly under the gun.

(Ophelia roars over Ireland. Image source: NASA Worldview.)

On October 14, Ophelia hit major hurricane status as it moved swiftly toward Europe. Packing 115 mph maximum sustained winds over a region of ocean where we’ve never recorded this kind of powerful storm before, Ophelia set its sights on Ireland. Crossing over warmer than normal North Atlantic Ocean waters, the storm maintained hurricane status up to 12 hours before barreling into Ireland. At that time, cooler waters caused the storm to transition to extra-tropical. But this transition was not enough to prevent Ireland from being struck by hurricane-force gusts up to 119 mph, storm surge flooding, and seeing structural damage reminiscent to a category one storm.

360,000 power outages and two deaths were attributed to a storm that should have not maintained such high intensity so far north and east. Yet another historic storm that forced the National Hurricane Center to shift its tracking map east of the 0 degree longitude line (Greenwich) since they had not planned for a hurricane or its tropical remnants to move so far out of the typical zone for North Atlantic hurricanes (see image at bottom of page).

(Human-caused climate change produces angrier seas off Ireland as amped-up Ophelia rages.)

As with many of the recently powerful storms, 1 to 2 degree Celsius above average sea surface temperatures were a prime enabler allowing Ophelia to maintain such high intensity so far north. And under the present trend, it appears that the Atlantic coasts of Spain, Portugal, France, Ireland and England are now all more likely to see tropical storm and hurricane impacts in the future as sea surface temperatures continue to rise. In the past, strikes by tropical cyclones to places like Ireland were considered to be rare — with the last Hurricane to impact Ireland being Debbie in 1961. But recent climate science studies indicate that global warming is likely to increase the frequency of hurricane and tropical storm impacts to Northern Europe:

In a paper published in April 2013, the Royal Netherlands Meteorological Institute predicted that by the year 2100, global warming would greatly increase the threat of hurricane-force winds to western Europe from former tropical cyclones and hybrid storms, the latter similar to Hurricane Sandy in 2012. One model predicted an increase from 2 to 13 in the number of cyclones with hurricane-force winds in the waters offshore western Europe. The study suggested that conditions favorable for tropical cyclones would expand 1,100 km (700 mi) to the east. A separate study based out of University of Castile-La Mancha predicted that hurricanes would develop in the Mediterranean Sea in Septembers by the year 2100, which would threaten countries in southern Europe.

The present Atlantic hurricane season can now only be described as a surreal caricature of what we feared climate change could produce. Texas, Florida, Puerto Rico and a dozen or more Caribbean islands are now devastated disaster areas. Some locations may feel the effects of the off-the-charts powerful storms enabled by a warmer than normal ocean for decades to come. Puerto Rico, unless it receives far more significant aid from the mainland than the Trump Administration appears to be willing to provide, may never fully recover.  And now Ophelia has maintained hurricane status until just twelve hours before striking Europe’s Ireland as a powerful extra-tropical storm.

2017 has also been an extraordinary year basin-wide by measure of storm energy. Total accumulated cyclone energy (ACE) for the North Atlantic as of October 15 was 222.5. So far, according to this measure, 2017 is the 7th strongest hurricane season ever recorded since records began in 1851. The most intense season, 1933, may see its own record of 259 ACE exceeded over the coming days and weeks. For storms still appear to be forming over record warm waters. According to the National Hurricane Center, a disturbance off the East Coast of the United States now has a 40 percent chance of developing into the season’s 16th named storm over the next 48 hours. Meanwhile, during recent years, powerful late October storms like Matthew and Sandy have tended to crop up over warmer than normal ocean waters even as late season storms ranging into November and December appear to be more common. In other words, we’re not out of the woods yet and 2017 may be a year to exceed all other years for total measured storm intensity as well as overall damage.
