Daily weather updatesCouple of Clippers – Moderating Temperatures Next Week
Coldest Super Bowl on record? It was 5F Sunday afternoon outside U.S. Bank Stadium. You call that cold? I’m proud of how the city, state and 10,000 volunteers stepped up to be good hosts. Minnesota Nice completely overwhelmed Minnesota Ice.
Pulling Out of the Deep Freeze. Yes, this week will be a good 10F colder than average, but ECMWF guidance shows 20s; even a few low 30s next week. A higher sun angle will make subzero temperatures more rare as we move into late February. Twin Cities numbers: WeatherBell.

Hurricane Center: Harvey’s “Overwhelming” Rains Were Likely Nation’s Most Extreme Ever. A staggeringly large area picked up staggering amounts of rain from Harvey. Jason Samenow reports for Capital Weather Gang: “Hurricane Harvey unleashed a tropical deluge probably unsurpassed in U.S. history, the National Hurricane Center says. In an in-depth meteorological review of the storm released Thursday, the center said it was unable to identify any past storm that had unloaded so much rain over such a large area. “[T]he areal extent of heavy rainfall is truly overwhelming, literally and figuratively,” the report said about the storm, whose catastrophic flooding engulfed Southeast Texas in August’s final week last year, killing 68 people. Such extreme rain amounts — which only have a 1 in 1,000 chance of happening in a given year — covered an enormous area, an accompanying geographic analysis showed…”

Climate Stories…
Polar Vortex: How the Jet Stream and Climate Change Bring on Cold Snaps. Because what happens in the arctic doesn’t stay in the arctic. A story at InsideClimate News explains how a rapidly warming arctic may be altering the jet stream: “…Rutgers University climate scientist Jennifer Francis has found “robust relationships” between Arctic warming and a wavier jet stream. Melting sea ice speeds up the warming of the Arctic because open water absorbs more heat. And that, in turn, leads to even more sea ice melting. In that vicious cycle, Arctic temperatures are rising twice as fast as the global average. And that’s reducing the temperature contrast that’s one of the jet stream’s main engines, Francis said. More extreme and persistent swings in the jet stream may also be shaping a North American winter weather pattern that’s been common the past few years—a warm and dry West, especially California, and cold waves in the Eastern U.S…”
ExxonMobil Issues Climate Report: From Climate Nexus: “World demand for oil could dip substantially by 2040 if policies to curb warming are aggressively implemented, ExxonMobil said in a climate-impact analysis released Friday. The oil giant’s shareholders, including financial giants BlackRock and Vanguard, backed a proposal last year requiring Exxon to provide analysis of how climate policies will impact its bottom line in an increasingly warming world. The analysis paints a mostly rosy future for the oil and gas industry, saying that even aggressive climate policy poses “little risk” to the company. However, the report does not address the multiple lawsuits facing Exxon and other fossil fuel giants, while some of the company’s analysis–including its predictions for the number of electric vehicles on the road by 2040 and the assumption that carbon capture technologies will allow the continued use of fossil fuels–has been challenged by experts.” (New York Times $, FT $, Reuters, AP, Axios, Quartz, The Hill)
Study Confirms Carbon Pollution Has Ended the Era of Stable Climate. ThinkProgress reports: “Recent temperatures experienced across Europe and North America are unprecedented in the past 11,000 years, a new study in the journal Nature finds. Significantly, the new study found that the average temperature of the last decade (between 2007 and 2016) exceeded the warmest centuries of the last 11,000 years by more than 0.5°F — which is much larger than century-scale changes have been over the pre-industrial era. This research confirms findings from 2013 that human-caused carbon pollution has ended the stable climate that enabled the development of modern civilization, global agriculture, and a world that could sustain a vast population…”

Record Number of Scientists Running for Office in 2018. Here’s a clip from TheHill: “At least 200 individuals with backgrounds in science, math, engineering and technology have launched bids for state House seats across the country, according to HuffPost. The number marks the largest number of scientists to run for office in modern history. The PAC 314 Action told the outlet that the candidates were running in elections for 7,000 state legislature seats. “The sheer number is really astonishing,” the group’s founder, Shaughnessy Naughton, told the outlet. The PAC’s membership expanded from 4,000 to 400,000 in 2017…”
Climate Change Could Swamp Your Muni-Bond Portfolio. The Wall Street Journal has the story: “…Other California localities have told courts one thing and investors another regarding climate change. In a similar lawsuit, San Francisco claims it faces “imminent risk of catastrophic storm surge flooding.” But in a bond offering last year, the city said it is “unable to predict whether sea-level rise or other impacts of climate change or flooding . . . will occur.” San Mateo County claims in another suit that there is a 50% chance that a “devastating three-foot flood . . . occurs before 2030.” The county uses boilerplate similar to San Francisco’s to play down such risks in its communications to bondholders. These jarring inconsistencies have led Exxon Mobil , a target of the lawsuits, to seek judicial relief...”

Our Coastlines Are Eroding, Along with Our Democratic Norms and Institutions. Climate scientist Ben Santer has an Op-Ed at Scientific American; here’s an excerpt: “…Over the past year, the United States has witnessed a different kind of erosion. There has been an erosion of our democratic norms and institutions, with attacks on the legitimacy of courts and judges, the professionalism and integrity of intelligence agencies, and the fairness and patriotism of the press. Protections on clean air, clean water and human health are crumbling before our eyes. The boundaries of our national parks are eroding. The borders between what is real and what is imaginary are eroding, caving in to the relentless assault of “alternative facts,” outright lies and declared reality. Civility and decency are eroding on a daily basis, undercut and weakened by language emanating from the White House. Trust is eroding. The rest of the world no longer trusts our word…”

How Bill Gates Aims to Clean Up the Planet. Here’s a clip from The Guardian: “…The idea is grandiose yet simple: decarbonise the global economy by extracting global-warming carbon dioxide (CO2) straight from the air, using arrays of giant fans and patented chemical whizzery; and then use the gas to make clean, carbon-neutral synthetic diesel and petrol to drive the world’s ships, planes and trucks. The hope is that the combination of direct air capture (DAC), water electrolysis and fuels synthesis used to produce liquid hydrocarbon fuels can be made to work at a global scale, for little more than it costs to extract and sell fossil fuel today. This would revolutionise the world’s transport industry, which emits nearly one-third of total climate-changing emissions. It would be the equivalent of mechanising photosynthesis…”

Warming in Minnesota. The Weather Channel has undertaken an ambitious (and in my opinion, effective) project, localizing the impact of climate change on all 50 states. Here is a clip of what they’ve posted for Minnesota: “…Since the start of the 21st century in 2001, Minnesota has experienced 10 of its top 20 warmest years on record dating to 1895. Two of the state’s top five warmest years have happened in the last five years: 2012 was the second-warmest year, and 2016 ranked as the fifth-warmest year…Since the start of the 20th century, the annual average temperature statewide has risen more than 2 degrees Fahrenheit. Most of the warming has occurred in winter. In December-February, temperatures have risen about four degrees Fahrenheit (1896-2017)...”

Climate Change Could Make your Basement Uninsurable in the Next Decade. Bloomberg explains why: “Private property below ground in New York and Mumbai may not be insurable in the next decade if climate change advances, the head of one of Europe’s largest insurers said “If you go much further to 2020, 2030, we can clearly say that at a scenario between 3 and 4 degrees, it’s not insurable anymore,” Thomas Buberl, chief executive officer of AXA SA, said on a panel at the World Economic Forum’s annual meeting in Davos, Switzerland. “Your basement shop in New York, your basement shop in Mumbai will at this point not be insurable anymore.” Global warming and the subsequent rise of extreme weather events are expected to increase insurance companies’ claims, possibly to the point where certain assets are too risky to underwrite new policies in some places. The number of natural disasters from hurricanes in the Atlantic Ocean to wildfires in California increased last year. As sea levels rise, cities on coastlines will be much more vulnerable to flooding…”
