July 13, 1933: An intense heat wave affects Grand Marais with a high of 90, extremely rare for that location. Most of Minnesota would exceed 100 degrees on this date.
July 13, 1890: A tornado hits Lake Gervais north of St. Paul. People rush from St. Paul to help victims and look for souvenirs. One reporter notes that ‘nearly everyone who returned from the disaster last evening came laden with momentoes (sic) denoting the cyclone’s fury.’
I’ve said it before, I’ll say it again: when weather stalls bad things tend to result: epic heat waves, historic droughts, biblical floods. Tell that to residents of northern and central Minnesota, where 1-2 MONTH’S worth of rain fell on Monday; as much as 5-9 inches.
Central Minnesota Tornado Overview. The Twin Cities office of the National Weather Service has a preliminary assessment of the tornadoes that struck from Litchfield to Watkins and Waite Park Monday: “On Monday evening July 11, 2016 thunderstorms produced at least four tornadoes across central Minnesota. The National Weather Service in the Twin Cities has sent out 3 storm survey crews to assess the damage. As of Tuesday morning, there has been only one minor injury reported. Based on the preliminary storm reports, areas hardest hit were the town of Watkins MN, northwest Litchfield MN, as well as locations near St Cloud MN. This part of the state is highlighted by the red box on the map to the right. Further information is given below and additional facts about the strength of the tornadoes will be released as the become available.”
Two of the 3 survey teams have completed their investigations. Litchfield Tornado Damage Survey Results: EF-2 strength with a max wind of 115 mph. Length was 1 mile with a max width of 150 feet;
Watkins Tornado Damage Survey results: EF-2 strength with max wind of 125 mph. Length: 2 miles. Max width: 600 feet.

Slight Severe Risk Southeastern Minnesota, Southwest Wisconsin. NOAA SPC shows a slight risk of strong to severe storms firing along the leading edge of cooler, drier air later today.
What The National Weather Service Social Media Warning Stream Has Shown Us. Ian Livingston has some interesting information and perspective at Capital Weather Gang: “As someone fascinated with the warning process and how it is communicated to the public, I have followed the severe warning accounts since inception in June 2014. Seeking out the zero warning, or one with no ambient population, is actually something of a hobby. (I know, don’t judge.) Looking for more, I made a data request on what has been issued since the Twitter accounts became operational. I was fortunate enough to connect up with the National Weather Service, and they supplied the raw data they’ve obtained while developing these channels...”
Seattle Crowned “Least Severe” Weather Spot In The Nation. Not a good place to chase tornadoes. Here’s an excerpt from KOMO News: “Fresh off last month’s blog showing Seattle was the only spot in the lower 48 with no severe thunderstorm warnings this year comes more research that cements Western Washington as among one of the most boring places in the nation when it comes to severe weather. Ian Livingston with the Washington Post’s Capital Weather Gang has been looking into the effectiveness of the National Weather Service’s social media efforts in getting severe weather warnings to the public, also learning more about when you can be expected to get severe weather warnings…”
Heat Waves Kill. Now We Know Why. Increase the background temperature by only 1-2C and the risk of (extreme) heat goes up substantially; rare events are suddenly not as rare. Here’s an excerpt from U.S. News: “…What the study shows is that climate change was responsible for 506 of the 735 summer deaths recorded in Paris during the heat wave, while 64 deaths out of a total of 315 heat-related deaths in London were caused by global warming. The study used the new tools researchers have at their disposal to put the results of much better climate model simulations of the European heat wave into a health impact assessment of death rates. In order to accurately project the cause of those deaths, the researchers ran thousands of high-resolution regional climate model simulations...”

Future of Natural Gas Hinges on Stanching Methane Leaks. The New York Times reports; here’s an excerpt: “…Methane has many sources, including flatulent cows and decomposing landfills. But the oil and gas industry may be the nation’s biggest emitter of leaked methane, gas that might otherwise stay underground for eons. While coal still predominates in many parts of the world, especially in emerging economies, natural gas has already replaced coal as the United States’ leading fuel for power plants. But the American energy industry lets enough natural gas escape each year to meet the heating and cooking needs of about seven million homes annually. That runaway gas also creates about the same short-term climate impact as 240 coal-fired power plants, according to the Environmental Defense Fund...”

Meteorologists Shouldn’t Just “Stick To The Weather”, They Should Openly Discuss Climate Change. Something I’ve been trying to do since the last 90s, for better or worse. We need to do a better job connecting the dots, because climate and weather are flip-sides of the same coin. Jason Samenow at Capital Weather Gang agrees: “…However, despite overwhelming evidence that climate change is impacting weather, George Mason University’s Center for Climate Change Communication found that only “a minority” of television weathercasters “feel very comfortable” presenting climate change information on air. Most say discussing climate change won’t help their careers. Some fear discussing the role of climate change on weather will upset their viewers — or even newsroom management. But TV weathercasters need to find the courage to communicate about climate change responsibly. The science is on their side…”
Climate Change May Already Be Shifting Clouds Toward the Poles. NPR follows up on new research: “The way clouds cover the Earth may be changing because of global warming, according to a study published Monday that used satellite data to track cloud patterns across about two decades, starting in the 1980s. Clouds in the mid-latitudes shifted toward the poles during that period, as the subtropical dry zones expanded and the highest cloud-tops got higher. These changes are predicted by most climate models of global warming, even though those models disagree on a lot of other things related to clouds, says Joel Norris, a climate scientist at the University of California, San Diego…”

Fossil Fuel Industry Risks Losing $33 Trillion to Climate Change. Bloomberg reports: “The fossil fuel industry risks losing $33 trillion in revenue over the next 25 years as global warming may drive companies to leave oil, natural gas and coal in the ground, according to a Barclays Plc energy analyst. Government regulations and other efforts to cut carbon emissions will inevitably slash demand for fossil fuels, jeopardizing traditional energy producers, Mark Lewis, Barclays’s head of European utilities equity research, said Monday during a panel discussion in New York on financial risks from climate change...”
The Extreme Weather Defense Nobody Wants. In theory a concrete home could survive major tornadoes and hurricanes but are they worth the cost, and who wants to live in a bunker? Here’s an excerpt from Bloomberg View: “…People have never caught on to concrete as a warm and fuzzy material,” said Richard Longstreth, an architectural historian at George Washington University. The typical reaction is “‘Oh, you live in a bunker,’ or something like that.” Oh, and it would make the problem worse. “The emissions in concrete production are huge,” noted Alan Organschi, who teaches at the Yale School of Architecture. “Concrete is a very robust material, but it also is one of the very things that is producing climate change.” He said a better solution is building homes out of heavy timber, which can be just as resilient as concrete and no more expensive…”
Dems Look To Shame Exxon over Climate. Here’s an excerpt from TheHill: “…In a joint resolution offered by Sen. Sheldon Whitehouse (D-R.I.) and Rep. Ted Lieu (D-Calif.), the members say they disapprove of “activities by certain corporations, trade associations, foundations and organizations funded by those corporations to deliberately mislead the public and undermine peer-reviewed scientific research about the dangers of their products, and to deliberately cast doubt on science in order to protect their financial interests.” The resolution equates the fossil fuel industry to the tobacco sector, which was slammed by lawsuits alleging it mislead the public about the dangers of smoking. And it says fossil fuel companies should “cooperate with active and future investigations into” their climate science...”
Senators Launch Resolution, Speech Blitz Calling Out #WebOfDenial Blocking Action on Climate Change. Here’s a slightly different perspective from DeSmogBlog: “Today and tomorrow, at least 19 U.S. Senators who understand the need to clear the PR pollution that continues to block overdue climate policy action will speak out on the Senate floor in support of the Senate Web of Denial Resolution calling out the destructive forces of fossil fuel industry-funded climate denial. Championed by Senators Whitehouse, Markey, Schatz, Boxer, Merkley, Warren, Sanders, and Franken, the resolution condemns what they are calling the #WebOfDenial — “interconnected groups – funded by the Koch brothers, major fossil fuel companies like ExxonMobil and Peabody Coal, identity-scrubbing groups like Donors Trust and Donors Capital, and their allies – developed and executed a massive campaign to deceive the public about climate change to halt climate action and protect their bottom lines…”
ExxonMobil: New Disclosures Show Oil Giant Still Funding Climate Science Denial. Here’s a clip from DeSmogBlog: “…But the latest disclosures on donations by ExxonMobil, reported publicly here for the first time, show it continues to support organisations that claim greenhouse gases are not causing climate change, or that cuts to emissions are a waste of time and money. Organisations including the American Enterprise Institute, the American Legislative Exchange Council and the National Black Chamber of Commerce — all organisations with a record of misinformation on climate science — all received grants in 2015 from ExxonMobil. The 2015 tally brings the total amount of known Exxon funding to denial groups north of $33 million since 1998…”
Food Shortages and Sea Level Rise U.S. Voters’ Top Climate Change Concerns. The Guardian has the story: “…Diminishing food and water security and ruinous sea level rise are the leading climate change concerns of a section of the American electorate that is aghast at the lack of discussion of global warming during the presidential debate. A Guardian US survey of its readers found that pressure on food and water supplies is considered the most important consequence of climate change. Sea level rise, which is set to inundate coastal areas currently occupied by millions of Americans, is second on the list of the most urgent issues…” (File photo: Nick Ut, AP).
Minnesota Advocates “Pleasantly Surprised” With New U.S. Bancorp Climate Policy. Here’s the intro to a story at Midwest Energy News: “Minnesota climate activists say they are “pleasantly surprised” after Minneapolis-based U.S. Bancorp issued a new environmental policy in June that will reduce lending for coal-fired power plants, coal mines and other environmentally harmful projects. Two bank officials have been meeting with MN350 members for the past several months on a new environmental policy that would discourage lending to fossil fuel interests. Advocates say the policy move — which they add could be stronger — is important because U.S. Bancorp (the parent company of U.S. Bank) is one of the largest financial services companies in the United States...”

Another Inconvenient Truth: It’s Hard To Agree How To Fight Climate Change. The New York Times reports; here’s an excerpt: “…But the movement that started with a straightforward mission — to get more people to appreciate the dangers of climate change as a precursor to action — is feeling growing pains. What may seem like a unified front has pronounced schisms, with conflicting opinions on many issues, including nuclear power and natural gas, that are complicating what it means to be an environmentalist in this day and age. The factional boundaries are not hard and fast, with groups shifting their positions as the science and waves of activism evolve...” (File image: earth.nullschool.net).
