Severe Risk Central and Southern Minnesota - A Touch Cooler Next Week

An Unlikely Weather Map

Weather is a deep dive into chaos theory. Computers help but model simulations only go so far. I've been scratching my head more than usual in 2015. From extreme drought to raging floods in Texas. A record-setting wet July across the Midwest; surplus soil moisture helping to depress corn prices. Record 100-degree-plus heat grips Oregon and Washington state. A record summer for wildfires in Alaska.

August is prime time for hurricanes, but Florida has gone nearly a decade (!) without experiencing one of these fearsome storms. A recent poll suggests 1 in 3 Floridians won't evacuate if a Category 1 hurricane is steamrolling their way. Crazy. Apathy may breed disaster down the road.

A surge of moisture coupled with strong wind shear and instability aloft could spark strong to severe T-storms by evening, especially over the southern half of Minnesota. I'm just hoping my power stays on this time. Sunday looks drier with 80s and a light breeze. Longer range guidance hints at a few 70s by late next week.

I'm a glass-half-full guy but it's been a memorable summer: just warm enough, not too humid and an almost ideal rainfall pattern for farmers; just a handful of severe outbreaks. Perfect.


Slight Severe T-storm Risk. NOAA SPC has a slight risk of severe thunderstorms later toda over southwestern Minnesota, the greatest potential for hail and damaging winds south and west of the Twin Cities. Will the power stay on? Place your bets.


West Coast Heat Wave Threatens All-Time Records. Here's an excerpt from The Weather Channel: "...It's a fitting end to what will be one of the hottest Julys on record in parts of the Northwest. Seattle, Washington, and Astoria, Oregon, were both seeing their hottest July on record as of July 29, according to data from the Southeast Regional Climate Center. For Seattle, July 2015 could beat out August 1967 for the hottest month on record if the final average temperature for July exceeds 71.1 degrees. July was the third warmest on record through July 29 in Portland, Oregon, and fourth warmest on record for Yakima, Washington. High temperatures at or above 100 degrees are forecast for the Portland, Oregon, area through Friday, with middle to upper 90s expected this weekend..." (Interactive graphic: AerisWeather).


Crazy-Warm Temperatures Over Southwest Oregon and Northwest California. Cliff Mass provides good perspective on the blazing heat gripping the Pacific Northwest; here's an excerpt: "How often do you see temperatures of over 100F at a coastal location, with cool ( roughly 50F) water close at hand?   Well today for one!  Let's head down to the southwest corner of Oregon, near Brookings.   This is a region often called the Banana Belt of Oregon for having "tropical" temperatures any month of the year. Here is a map showing you today's maximum temperatures (F) over SW Oregon and NW California. Over 100F AT THE COAST at Brookings and at Gold Beach, just to its north..." (Heat index forecast above: AerisWeather).


Gulf Coast Soaking. Although model guidance (including the ECMWF) doesn't show any imminent tropical development, a temporarily stalled frontal boundary focuses heavy showers and T-storms on the Gulf Coast, with Tampa and Ocala picking up some 5-6"+ rains over the next 7 days. The heaviest storms should slosh south of Minnesota into next weekend.


A Tale of Two Seasons. It will very much feel like summer over the Southwest and southern Plains into mid-August, but a series of unusually strong storms pushing across Canada will puff almost September-like air into the Upper Midwest, Great Lakes and New England, taking the edge off the heat and humidity. GFS guidance from NOAA goes out 10 days.

What Warming Means for 4 of Summer's Worst Pests. A longer mosquito season in Minnesota? Just what I wanted to hear. Details via Climate Central; here's a snippet: "...As temperatures around the country rise, the areas that are conducive to such mosquitoes could expand, and the insects could start to emerge earlier in the year, meaning more opportunities for bites that could spread disease. After an unseasonably warm late spring, summer, and early winter in 2012, the U.S. experienced a West Nile Virus outbreak linked to the Asian Tiger mosquito, with some 5,600 people becoming infected. Asian Tiger mosquitoes tend to die off when temperatures venture outside a range from 50°F to 95°F and when relative humidity dips below 42 percent. A Climate Central analysis examined how warming would affect this range for cities around the country, showing how many more “mosquito suitable” days there were now compared to 1980..."


Interactive Wildfire Map. Here's a resource from Climate Central, showing wildfires around the USA. The west coast is bad enough with the ongoing drought, but check out Alaska, which on this map appears to be a suburb of hell.


Florida's Extended Hurricane Drought. No hurricanes in nearly 10 years? The Weather Channel takes a look at this (historic) quiet spell and a growing sense of apathy, especially among younger Floridians; here's an excerpt: "...There's little doubt that Florida's recent history with hurricanes – or lack of them, actually – plays a significant role in this. More than 9 1/2 years have passed since the last hurricane to make landfall in Florida (2005's Hurricane Wilma), by far the longest stretch of consecutive hurricane-free years for the state since 1851. Previously, the state's longest hurricane-free streak lasted five years, from 1980 to 1984. That's especially impressive when you consider the coastline of Florida spans more than 1,260 miles, and an average of eight hurricanes have formed each year since 2005. Since Wilma, more than 1 million people have moved to Florida, according to the latest U.S. Census data..."

Record Rains in July. Here's an excerpt of AerisWeather meteorologist D.J. Kayser's excellent blog post on record rains this month across much of the USA east of the Rockies: "...Heavy rain once again fell over parts of the central and southeast United States, leaving some locations with over 10″ of rain during the month. Indianapolis, IN, saw their wettest MONTH on record this July, with 13.14″ falling through July 29th. The previous monthly record for the Crossroads of America was 13.12″ back in July of 1875. It’s also been wet in parts of Texas (more on that in a moment) with 8.26″ falling in Abilene, TX, making it the wettest July on record..."


Devastating Floods Might Be More Common Than We Thought, Study Says. The Los Angeles Times has a summary of recent research; here's an excerpt: "...But some of the worst floods in coastal areas are caused by the unfortunate concurrence of big storm surges with high rainfall – a double-whammy for flooding, because it can result in the sea spilling over onto land while rivers and urban drainage systems overflow onto the streets. By examining these two phenomena together, researchers showed that heavy precipitation and high seas are occurring in tandem more often in many coastal cities, especially along the Gulf and Atlantic coasts of the U.S. The results were published this week in Nature Climate Change...."

Younger Floridians Discount Hurricane Threat. The fact that the USA hasn't experienced a Category 3 or stronger hurricane in a decade is one factor. Older people remember - and tend to have respect for hurricanes. But if you've never experienced one? Here's an excerpt from The Jacksonville Democrat: "Those who experience hurricanes rarely lose their awe for the forces of nature. Many young people, though, have no idea of the kind of devastation hurricanes can cause. Those are some of the conclusions that could be drawn from a July Mason-Dixon poll of Florida residents 10 years after the record breaking summer of hurricanes Katrina, Dennis, Rita and Wilma. “That millennial group — some of the younger ones were in elementary school the last time there was a hurricane,” said J. Brad Coker, managing director of the Mason-Dixon Polling & Research Inc..." (File photo: NASA).


In Microsoft's Nokia Debace, A View of an Industry's Feet of Clay. Disruption is no longer the exception but the rule. Smart companies are disrupting themselves (faster) before others do it for them. Here's an excerpt from The New York Times: "...Microsoft “just couldn’t imagine that a company that was once as strong and dominant as Nokia could have virtually no value.” He compared the swift rise of Apple and the withering fortunes of Nokia, BlackBerry and other once-thriving manufacturers to the arrival of an infectious virus. “We tend to think the strong will survive,” Mr. Dediu said. “But a virus is a very small thing that kills big things.” He continued: “It’s easy to say Microsoft was foolish and blame the chief executive. But when it happens to everyone, it’s an extinction event. A whole bunch of companies were disrupted. And it happened in the blink of an eye...” (Image credit here).


Obama Wants The U.S. To Be At The Forefront of Supercomputer Technology. Call me crazy but this sounds like a pretty good idea to me. Here's an excerpt from Gizmag: "President Obama has signed an Executive Order calling for the US to significantly up its game in the supercomputer space. The effort, known as the National Strategic Computer Initiative (NSCI), will aim to build the world's fastest supercomputer by 2025. The NSCI initiative will be an multi-departmental research, development and deployment effort focusing on the creation of a brand new supercomputer. The mission statement is essentially to make sure that the US has the most capable machine a decade from now, allowing for high-end computational problem solving in both the public and private sectors..."

Solar Now Cheaper Than Fossil Fuels For Many Small Businesses. EcoWatch has the story; here's the intro: "Solar power is the fastest-growing sourc eof electricity in the country, and now mom and pop shops can take part in the boom. Solar panels are usually seen on the roofs of residential buildings, schools, large companies or government institutions, but now, SolarCity is expanding its services to small and medium-sized businesses, or SMRs, the company announced. This move essentially allows local businesses to cut ties to their utility and save money against rising electricity costs with renewable energy..." (photo credit: flickr).

Climate Stories....

Earth Now Halfway to U.N. Global Warming Limit. New Scientist has the details; here's the intro: "It's the outcome the world wants to avoid, but we are already halfway there. All but one of the main trackers of global surface temperature are now passing more than 1 °C of warming relative to the second half of the 19th century, according to an exclusive analysis done for New Scientist. We could also be seeing the end of the much-discussed slowdown in surface warming since 1998, meaning this is just the start of a period of rapid warming. “There’s a good chance the hiatus is over,” says Kevin Trenberth of the National Center for Atmospheric Research in Boulder, Colorado..."

How The Pentagon Is Preparing For Climate Change In Each Part of the World. The Washington Post takes a look at a recent Defense Department report; here's an excerpt: "The Pentagon made the case Wednesday that the locations in the world most prone to instability and bloodshed also are the ones where climate change has the greatest impact, and laid out details about how top regional commanders are preparing for it. A report required by Congress covers a variety of climate issues affecting the military, noting how rising seas and severe weather can impact missions. But it also provides little-known details about how each geographic combatant command — a COCOM, in military-speak — is addressing climate change in the part of the world where they oversee operations..."

"Force Multiplier". The world is awash in risk. Climate change adds additional risk to the equation, with implications for food and water supplies, agriculture, migration and the potential for revolution (exhibit A: Syria). Here's more perspective on the Pentagon report from rtcc.org.


Climate Models Are Even More Accurate Than You Thought. Professional climate deniers like to squawk about how unrelieable the climate models are in the hands of those "alarmist climate scientists". It turns out they've been closer to the mark than you might think. Here's a summary of an article at The Guardian: "...There’s a common myth that models are unreliable, often based on apples-to-oranges comparisons, like looking at satellite estimates of temperatures higher in the atmosphere versus modeled surface air temperatures. Or, some contrarians like John Christy will only consider the temperature high in the atmosphere, where satellite estimates are less reliable, and where people don’t live. This new study has shown that when we do an apples-to-apples comparison, climate models have done a good job projecting the observed temperatures where humans live. And those models predict that unless we take serious and immediate action to reduce human carbon pollution, global warming will continue to accelerate into dangerous territory..."

Evangelicals Back Carbon Reduction Plan. Protection for the unborn apparently extends to future generations of unborn as well; here's an excerpt from The Washington Post: "More than 170 evangelical leaders have sent President Obama a letter backing a Clean Power Plan that will reduce carbon dioxide emissions from coal-burning power plants. The plan, which is expected to be released Monday (Aug. 3), aims to cut carbon pollution by 30 percent from 2005 levels. Coal industry leaders have said the plan will increase costs and have a minimal effect on climate change. The letter from evangelicals says that 230,000 “pro-life Christians” have contacted the Environmental Protection Agency in support of the plan..."


Drought-Hit Forests Store Less Carbon Dioxide Than Thought: Researchers. Here's the intro to a story at Reuters: "The world's forests are taking longer than expected to recover from increasingly frequent droughts, meaning their ability to store climate-changing carbon dioxide is smaller than previously thought, Utah University researchers said on Thursday.  If forests are absorbing less carbon dioxide, then the effects of climate change will be worse than past models had predicted, the Utah study published in the journal Science said..."

Jeb Bush: Humans Contribute to Climate Change. Is the GOP taking baby-steps toward acknowledging the reality of man-made climate change? It would appear so, based on Jeb Bush's recent (encouraging) interview with Bloomberg, featured at TheHill; here's the intro: "GOP presidential hopeful Jeb Bush says human activity is contributing to climate change and the country has an obligation to work to stop it. “I think it’s appropriate to recognize this and invest in the proper research to find solutions over the long haul but not be alarmists about it,” Bush said in an interview published Thursday with Bloomberg BNA. “We should not say the end is near, not deindustrialize the country, not create barriers for higher growth, not just totally obliterate family budgets, which some on the left advocate by saying we should raise the price of energy so high that renewables then become viable,” he added..."


Step Outside - Climate Change is Here. Here's an excerpt of an Op-Ed from the Editorial Board at The Sacramento Bee: "...if global warming doesn’t feel like a threat by now, it ought to. Last week, 16 leading scientists joined the former lead climate scientist for NASA in warning that glaciers in Antarctica and Greenland could melt 10 times faster than anyone thought. James Hansen, one of the first predictors of climate change – “alarmist and also right,” as Slate called him – reported that the goal we had all been told was safe, limiting global warming to a 2-degree Celsius temperature increase, actually won’t begin to control the damage. In as little as 50 years, according to the study published last Thursday in the open-access journal Atmospheric Chemistry and Physics, sea levels may rise 10 feet or more, inundating the world’s coastal cities..."


Before The Time of Global Warming, Spring Sprung Later. Here's a snippet from a story at Inside Climate News: "...According to one of the largest troves of ecological data from the past, living organisms are already responding to the rise in temperatures from global warming. By digitizing more than 11,000 records from the 19th century that chronicled the flowering of plants and trees, the springtime arrival of migrating birds, and the annual onset of frog mating calls, researchers at the Hawthorne Valley Farmscape Ecology Program in Harlemville, N.Y. have shown that spring is arriving as much as 14 days early as climate change accelerates..."

Canadian Reprieve - Record Wet July For Much of Midwest

Canadian Payback

Mea culpa.

Roughly 7 months out of the year the term "Canadian cold front" is a pejorative, a negative, cringe-worthy expletive. "Canada exports wheat, oil, hockey players and cold fronts!" But give credit where credit is due: much of America is broiling; tens of millions of our brethren wilting under a heat index above 100F. But a persistent west/northwest jet stream wind flow aloft has allowed a conga-line of (refreshing, wondrous!) Canadian cool fronts to burp south of the border, taking the edge off the heat from St. Paul to Detroit and Boston.

I'm sending a Hallmark thank you note to Canada for the comfortable, sun-scrubbed sky outside my window. A/C optional? Highly unusual for late July.

Fasten your seat belt and prepare to ride out some of the best weather of the year: 80s into next week, with occasional puffs of Canadian air keeping the dew point very tolerable - little chance of severe weather or monsoon rains. A few T-storms may pop up late Sunday, but most of the upcoming weekend will be dry and pleasantly warm.

Rainfall since June 1 is running 3.7 inches above average in the Twin Cities. No drought, no storms, no midsummer sweat. What's not to like?


Record Rains in July. Here's an excerpt of AerisWeather meteorologist D.J. Kayser's excellent blog post on record rains this month across much of the USA east of the Rockies: "...Heavy rain once again fell over parts of the central and southeast United States, leaving some locations with over 10″ of rain during the month. Indianapolis, IN, saw their wettest MONTH on record this July, with 13.14″ falling through July 29th. The previous monthly record for the Crossroads of America was 13.12″ back in July of 1875. It’s also been wet in parts of Texas (more on that in a moment) with 8.26″ falling in Abilene, TX, making it the wettest July on record..."


Drought-Free. It's remarkable how quickly the late spring drought has faded east of the Rockies. The latest U.S. Drought Monitor shows a few pockets of dry soil, but a total lack of drought from the Upper Midwest and Great Lakes into the Ohio Valley. One measure of how good the weather has been over such a huge area: favorable soil moisture and the prospect of a record corn harvest has depressed prices.


Best Chance of T-storms: Saturday Night. Model guidance brings a weak trough of low pressure through late Saturday, capable of a few hours of showers and thunder. By Sunday winds shift around to the northwest and we dry out with another welcome dip in humidity. The forecast looks relatively dry as we sail into early August.


An Extended Heat Wave For Much of America. Frequent intrusions of cooler, drier Canadian air will continue to take the edge off the heat from Minnesota across the Great Lakes into New England, but much of the USA fries under sweltering 90 and even 100-degree heat into mid-August, based on the 14 day GFS outlook at 500 mb.


Summer Swelter: Heat Wave Scorches from Coast to Coast. USA TODAY takes a look at broiling heat afflicting much of America; here's an excerpt: "Yes, it's summer, and it's supposed to be hot, but this is a bit on the extreme side. As of 2 p.m. ET Wednesday, 110 million Americans in at least 35 states were sweltering under a temperature of least 90 degrees, according to WeatherBell meteorologist Ryan Maue. About 35 million people were enduring a heat index of at least 100 degrees, he said..."

Manitoba Tornado Was An F2: Environment Canada. Here's the intro to a story at The Winnipeg Sun: "A massive tornado that struck western Manitoba this week has been given an preliminary rating which puts it in the category of large and violent, but not the worst that nature can serve up. Environment Canada says the twister that roared through the Virden region near the Saskatchewan boundary Monday evening was of the high-end EF2 variety. Such tornadoes can pack wind speeds ranging from 179 kilometres an hour to 218 kilometres an hour -- capable of lifting cars, ripping out trees and damaging roofs..."

Photo credit above: "This twister that tore through southwestern Manitoba on Monday night has been classified as an F2." (GREG JOHNSON/TORNADO HUNTERS PHOTO).


3-Hour Canadian Tornado Likely One Of The World's Longest. I still have trouble believing that this was ONE TORNADO, rather than a series of tornadoes spinning up under the same parent supercell. Then again these days I wouldn't rule anything out. Here's a clip from USA TODAY: "he massive tornado that roared across the Canadian province of Manitoba late Monday was on the ground for nearly 3 hours — likely one of the longest-lasting on record in Canada and perhaps the world. No injuries or deaths were reported. The longest tornado recorded is the infamous Tri-State tornado that lasted for about 3.5 hours, ravaging the Midwest in March 1925 and leaving hundreds of people dead in its wake..."

July 12 Storm Damage Clean-up Continues. Thanks to AerisWeather meteorologist Todd Nelson, vacationing up at Craguns Resort on Gull Lake with his family. He sent me these photos on Wednesday, and said "All I can hear is distant chainsaws...huge piles of lumber everywhere!"


Evidence of Microburst Winds at Maddens Resort. State Representative Mark Anderson and his wife Barbara took me out on Gull Lake Sunday to get a first-hand look at the damage in the Brainerd Lakes area. This is the employee housing at Maddens, missing much of the roof, evidence of severe wind damage everywhere. This is in line with Duluth NWS wind estimates of 100 mph in a series of downbursts. Much like a tornado the damage swaths were fickle and spotty, many areas spared, but other pockets of extreme damage, trees snapped like toothpicks. The damage path was linear, no evidence of rotation found in tornadic winds.


Awe-Inspiring. This is one of the photos I shared with the GCOLA, the Gull Chain of Lakes Association Gala event Monday evening up at the Grand View Lodge (which also suffered tree damage, but nothing like the southern end of Gull Lake). I snapped this panorama on my trusty iPhone about 4 miles east of Schaefer's grocery store in Nisswa, just north of Co. 13. It looked like the fist of God came crashing down, snapping trees in a swath maybe half a mile wide, again, consistent with severe downburst or microburst winds.


Poleward Shift in Derecho/Downburst Winds with Warming Climate? In response to a reader's question about frequency of these kinds of damaging, freakish wind storms I asked state climatologist Greg Spoden about trends he's witnessed. Are we imagining an increase, or does the data confirm an increase in these derecho/downburst wind events? Here is what Greg wrote:

"The National Weather Service Storm Prediction Center offers an excellent overview of derechos and derecho climatology here. In their section on derechos and climate change they reinforce Paul's comment about a poleward shift in the corridors of maximum derecho frequency." - Greg Spoden, State Climatologist


An Unusually Soggy July. AerisWeather meteorologist D.J. Kayser has an interesting blog post focused on the number of days with 1" or more of rain, compared to long-term averages; here's an excerpt: "...As you may have noticed above, both St. Cloud and the Twin Cities saw rain totals of over an inch this morning. So, we break out the 1″+ rain tracker once again today! The Twin Cities is now up to three days this year, all occurring during the month of July, with at least one inch of rain – half way toward the yearly average of six. St. Cloud has now seen nine days this year with at least one inch of rain, one away from matching the number seen during 2014. This also marks the fourth one inch or greater rain this month in St. Cloud..."


How To Stay Safe When The Big One Comes. Here's a follow-up to the recent (terrifying) piece in the New Yorker focused on the probability of a monster 9.0+ earthquake impacting the Pacific Northwest. This (new) New Yorker article puts the threat into better focus and context and provides advice on steps residents can take to lower their risk; here's an excerpt: "...So a better analogy than toast is this: the Cascadia earthquake is going to hit the Pacific Northwest like a rock hitting safety glass, shattering the region into thousands of tiny areas, each isolated from one another and all extremely difficult to reach. That’s why Murphy’s plan involves, in his words, “leasing, buying, or stealing any helicopter I can get my hands on.” Helicopters can’t do everything, but they can, at least, get almost anywhere. (FEMA has also made arrangements with the U.S. Navy Third Fleet to conduct a massive sea-lift operation for those stranded on the coast—but, for logistical reasons, it will take the fleet seven days from the time of the quake to arrive.)..."

What It Feels Like To Go Viral. Here's an excerpt of a fascinating piece from Pacific Standard: "Let's get some definitional housekeeping out of the way: There is no pageviews threshold for what a piece of #content needs in order to, as they say, “go viral.” It's a moving target that shifts from person-to-person, organization-to-organization, on a monthly, even daily, basis. If you normally have 2,000 daily readers, then you get 20,000, that's viral. If you're the New York Times and you get 20,000, something has gone horribly wrong. Pageviews matter, but relativity matters more..."

New Report from Anti-Poverty Group Debunks Claim That Coal Is Good For Poor People. Here's the intro to a story at ThinkProgress: "The coal industry and its supporters often argue that coal is still a relevant energy source because it’s cheap, and cheap electricity reduces energy poverty. But on Tuesday, Oxfam Australia directed an entire report to Australia’s government, saying that for the one billion people living without electricity, coal is more expensive than renewable energy sources. “Renewable energy is a cheaper, quicker, and healthier way to increase energy access,” the report states. “Coal is ill-suited to meeting the needs of the majority of the people living without electricity...”


On The Economics Of The End of The World As We Know It. At the risk of sticking a toe into a puddle of gloom and doom - how do we measure and price risk, including the risk of cataclysmic changes brought on by climate change? Here's an excerpt from The Economist: "...However, estimating these benefits means that we need to determine the value of a reduction in preventing a possible future catastrophic risk. This is a thorny task. Martin Weitzman, an economist at Harvard University, argues that the expected loss to society because of catastrophic climate change is so large that it cannot be reliably estimated. A cost-benefit analysis—economists’ standard tool for assessing policies—cannot be applied here as reducing an infinite loss is infinitely profitable..."


Defense Department to Congress: Global Warming is a "Present Security Threat". My youngest son flies helicopters for the Navy - I can tell you for the fact that the U.S. Navy is taking climate change, climate volatility and rising seas very seriously. Andrew Freedman at Mashable has the story - here are a few snippets that got my full undivided attention: "For the first time, the U.S. Department of Defense has detailed what it views as its greatest challenges related to climate change. In a report to Congress, the Defense Department said that global warming poses a "present security threat, not strictly a long-term risk." The report, delivered to the Senate Appropriations Committee on Tuesday and publicly released Wednesday, further stated the Defense Department is "already observing the impacts of climate change in shocks and stressors to vulnerable nations and communities," including in the United States, the Arctic, Middle East, Africa, Asia and South America.....Studies published in June found that humanity is rapidly depleting a third of the world's largest groundwater aquifers, with the top three most stressed groundwater basins in the political hotspots of the Middle East, the border region between India and Pakistan, and the Murzuk-Djado Basin in northern Africa..."

Climate Change Will Cause Increased Flooding in Coastal Cities. Here's an excerpt from Forbes: "...Another paper, published yesterday in Nature, had less fanfare than the Hansen paper, but shows the severe danger of flooding in coastal regions, particularly in the United States. This risk isn’t directly from sea-level rise, but from the intensification of storm surges and increased precipitation that are secondary effects of climate change. Flooding risk in any particular place depends on a number of factors: the flatness of land right by the water, how steep the continental shelf is off the coast, the number and severity of storms, etc. That’s why much of the state of Florida is at greater risk than coastal cities in California. As the Nature paper shows, heavier rainfall combines with storm surges, the rush of water toward the shore during major storms, to amplify flooding..."

Get Ready for Ugly As Markets Begin To Deal With Climate Crisis. Here's an excerpt of a story at EcoWatch that made me do a double-take: "Advocates of “market-based” climate solutions paint pastel pictures reflecting smoothly adjusting macro-economic models. Competitive markets gradually nudged by carbon pricing glide into a low carbon future in a modestly disruptive fashion, much as sulfur pollution from power plants was scaled back in the 1990’s. But commodity markets for oil and gas don’t work that way. These real markets are poised to savagely strand assets, upset expectations, overturn long established livelihoods and leave a trail of wreckage behind them—unless climate advocates start owning the fruits of their own success and preparing for the transition. Schumpeter’s destructive engine of capitalism is about to show its ugly side..."
