77 F. high temperature in the Twin Cities Thursday.
83 F. average high on July 28.
84 F. high on July 28, 2015.
July 29, 1917: The hottest temperature ever recorded in Minnesota, 114.5 degrees, occurs at Beardsley.
July 29, 1849: Severe storms hit the newly constructed post of Ft. Ripley between 3 and 5 AM. W.J. Frazier, Head Surgeon notes: ‘Rain and hail with much thunder and lightning and very high winds breaking many trees.’
Cool Canadian Breeze – Hot “American Air” Next Week
A hype-happy national media talking about weather is like watching an excitable puppy with a new toy. Think about it: polar vortex, heat domes, now “corn sweat”? When in doubt make stuff up.
I am guilty of routinely disparaging Canada and I take full responsibility for my transgressions. Much of the winter we talk about “Canadian air” as a pejorative, a diss. I wonder if TV meteorologists in Winnipeg or Toronto complain about hot, sweaty “American air” moving in?
I should get a research grant and study that for 10 years.
Today I just can’t get enough of a fresh breeze from Ontario; high near 80F with a very comfortable dew point in the 50s. And no obnoxious red blobs on Doppler, capable of chasing you indoors. A taste of September.
Temperatures over the weekend should be warm enough for the lake or pool – another wave of antiperspirant heat pushes the mercury into the low 90s Tuesday and Wednesday next week. More severe T-storms may sprout as early as Monday.
If anyone asks Minnesota’s mosquito season is 34 days longer now than it was in the 1980s. The welcome details below.
Mosquito Season Growing Longer. Longer growing season – longer boating season – more time for mosquitoes to breed. 34 days longer since the 1980s? Good grief. Here’s an excerpt from Climate Central: “…Climate Central analyzed how the number of days each year with ideal conditions for mosquitoes has been changing since 1980. We found that most major cities in the country (76 percent) have seen an overall increase in days conducive for mosquitoes in the past 36 years, and many regions have seen the mosquito season increase by half a month or more. Among the 200 largest metro areas in the U.S., 10 cities have seen their seasons grow by a month or more over this relatively short period of time. Overall, 125 cities are now seeing their average annual mosquito seasons at least five days longer than they were in the 1980s…”
Slow Warming Trend. Today will be the most comfortable day in sight; afternoon temperatures in the 70s with a dew point in the 50s. Temperatures mellow over the weekend; NOAA models hint at 90s by the middle of next week. Model ensemble above: Aeris Enterprise.
Sweating Under The Heat Dome. It could be worse – you could be living in Houston. Here’s an excerpt of an Op-Ed at The New York Times: “…First, most conventional wisdom is useless. Yes, you might feel a little cooler if you wear linen and cotton instead of polyester, along with a ridiculous “S.P.F.” sun hat. (Really, is there any other kind?) As for those sunscreens that promise to keep you cool, they do so for the five seconds you’re spraying them on. When it comes to bugs, torches dipped in citronella fuel might keep your patio marginally pest free, but at the expense of warming yourself near, well, a fire. So often, self-protection in summer comes down to a choice of which feels less nasty on the skin: sunscreen or bug repellent...”
The World’s Biggest, Fastest Firefighting Jet Is About to Take Off. We’re going to need a bigger plane. Here’s a clip from eenews.net: “On May 5, a big, red-and-white Boeing 747 made a low pass over the airport here and then dropped about 10,000 gallons of water, shrouding a nearby field in mist as a crowd including the state’s governor, a phalanx of local politicians and Forest Service representatives looked on. The plane, a converted former passenger jet, is about to enter service here as the biggest and fastest airborne firefighting jet in the world. It is capable of reaching almost any wildfire in the West in about three hours. Onlookers were excited about the plane’s 19,200-gallon capacity for carrying fire retardant, but less interested in its national reach. Many of them were more focused on the ugly experiences they’ve had right here with fast-spreading wildfires…”

Why The Ocean Is Warmer Than Usual And Could Stay That Way For A While. Here’s an excerpt of a story at California’s East Bay Times: “…The El Nino pattern heating up our ocean has been a semi-regular visitor to this region far longer than the phrase “global warming.” But this particular El Nino — now in its third summer — is more profound, and sticking around longer, than previous El Ninos. Just as hurricanes have become more frequent and more severe, this El Nino might be as big and gnarly as it is because of climate change. Whatever the cause, the warm ocean temperatures are changing the definition of “normal” when it comes to the area’s fish, mammals and birds...” (Image credit: earth.nullschool.net).
Forecast First: Warmer Temps Favored Across Entire U.S. And no, we can’t thank or blame El Nino this time around; here’s the intro to a story at Climate Central: “For the next three months, above-normal temperatures are favored across the U.S., from coast to coast and Mexico to Canada, as well as Alaska, according to government forecasts. In archives that go back to 1995, that’s never happened, Dan Collins, a forecaster with the National Oceanic and Atmospheric Administration’s Climate Prediction Center, said. While it doesn’t mean that a three-month-long heat wave is in store, or that there won’t be cooler spells here and there, it does up the odds that 2016 will rank among the hottest years on record for the country. It’s also a mark of the overall warming trend, courtesy of heat-trapping greenhouse gases accumulating in the atmosphere…” Map credit: NOAA
NOAA to Develop New Global Weather Model. Here’s are a few excerps of a press release from NOAA: “NOAA took a significant step toward building the world’s best global weather model today, a priority for the agency and the nation. NOAA announced the selection of a new dynamic core, the engine of a numerical weather prediction model, and will begin developing a state-of-the-art global weather forecasting model to replace the U.S. Global Forecast System (GFS)….The new dynamic core, Finite-Volume on a Cubed-Sphere (FV3), was developed by NOAA’s Geophysical Fluid Dynamics Laboratory in Princeton, New Jersey. The FV3 core brings a new level of accuracy and numeric efficiency to the model’s representation of atmospheric processes such as air motions. This makes possible simulations of clouds and storms, at resolutions not yet used in an operational global model…” (Image credit: NOAA).
Slimy Green Beaches May Be Florida’s New Normal. National Geographic reports; here’s a snippet: “…This is absolutely the worst,” says Evan Miller, an environmental activist and founder of Citizens for Clean Water. Miller lives in the tourist town of Stuart, 110 miles (177 kilometers) north of Miami. “We’ve never seen algae so thick. You can see it from space. There are places in Stuart that are on their third and fourth cycle of blooms now.” As the latest outbreak continues to play out with sporadic bursts of new algae blooms, dismayed Floridians are wondering if the recurring appearance of this tourist-repelling, fish-killing scum is their new normal. It may be...”
As Corn Devours U.S. Prairies, Greens Reconsider Biofuel Mandate. Bloomberg Politics has the story; here’s the intro: “Environmentalists who once championed biofuels as a way to cut pollution are now turning against a U.S. program that puts renewable fuels in cars, citing higher-than-expected carbon dioxide emissions and reduced wildlife habitat. More than a decade after conservationists helped persuade Congress to require adding corn-based ethanol and other biofuels to gasoline, some groups regret the resulting agricultural runoff in waterways and conversion of prairies to cropland — improving the odds that lawmakers might seek changes to the program next year...” (File photo: Star Tribune).
Our View: Conservatives’ Involvement Will Boost Energy Efforts. What can we all agree on, where is the common ground? Here’s an excerpt of an Op-Ed from The Mankato Press: “…The Minnesota Conservative Energy Forum was formed to give conservatives a voice on energy policy, according to Minnesota Public Radio News. And the most promising part of its agenda is that the forum doesn’t just tout traditional dependence on fossil fuels. The group is well-grounded in the reality that cleaner energy pays off in the long run. Members of the group say they want to stay away from the tired arguments over global warming. That’s a strategy that looks more promising for moving the state forward in its goals to give consumers cheaper, cleaner choices of energy…”
Elon Musk Makes a Libertarian Argument for Carbon Tax. Here’s an excerpt of an interview at Reno Gazette-Journal: “…With respect to some of the other elements for solar panels and EVs, the big issue we have is that in reality if you accept the scientific consensus every oil burning activity is subsidized, dramatically. If you believe there is a value to the CO2 capacity of the atmosphere and oceans and that CO2 capacity is not being paid for by the price at the gas pump or the coal that is being burned for electricity generation or whatever its use may be then every single fossil fuel burning activity is massively subsidized. This has become sort of an ideological issue because there are people who think that global warming is not true...”

Why Rich Neighbors Are Bad For You. Here’s a clip from The Washington Post: “The concept of “keeping up with the Joneses” has been around for more than a century. But in an era of high inequality, the pressure to match the lavish lifestyles of one’s neighbors has become all the more salient. A new paper from a Federal Reserve economist explores a potentially alarming way these pressures affects people’s financial lives. The paper from Fed economist Jeffrey Thompson suggests that Americans are borrowing more to keep up with wealthier members of society — particularly when it comes to buying and financing homes...” (Image credit: someecards).

What The U.S. Will Look Like When Your Kids Get Old. Gizmodo explains: “When climate change is in the news, it’s usually because of a scary new temperature record or a mass coral die-off, or because an enormous chunk of Greenland disappeared and nobody noticed. But at the end of the day, the thing that most of us really care about is how we’ll be affected. Now, NOAA is making it easier than ever to find out, with a new Climate Explorer app that shows just how screwed (or spared) your little sliver of the country will be. The first version of Climate Explorer launched in 2014, as part of a package of climate tools for planners interested in identifying vulnerable coastlines and flooding risks…”
Visitors to a Shrinking Alaskan Glacier Get a Lesson on Climate Change. A natural cycle? The photo above shows is a before/after photo from 1884 and 2004 at the Mendenhall Glacier in Alaska. Here’s a clip from NPR: “The Mendenhall Glacier is visible from the visitor center parking lot. But it’s still pretty far and if you traveled all the way to Juneau, Alaska, you probably want to get up close to the blue tinted ice. Touching the face of the glacier can be tricky. You’re separated by cold, silty water, and a hike over the ridge could take hours. Visitor center staff know that. And inside, they use it to prove a point. John Neary, director of the glacier’s visitor center, wants the more than 500,000 people who visit the Mendenhall Glacier each year to know that it’s rapidly retreating due to climate change...”
People Who Predict Floods Can’t Assume the Climate Isn’t Changing Anymore. Here’s an excerpt from ThinkProgress: “…Climate change has forced scientists, policymakers, flood control managers, urban planners, and especially anyone living in flood-prone areas to rethink how they assess the coming hazards of floods. In recent weeks, a series of terrible flood events in the United States has added a new sense of urgency to their discussions. Even abroad — recently in China, as well as in France, Germany, Nepal, South Africa and India, for example — floods have taken a significant toll on human life and property, exacerbating global concerns. Increasingly, experts in flood management and climate scientists have come to recognize that global warming — along with geography; topography; land use and development; infrastructure; and cultural beliefs — significantly contributes to the severity and frequency of floods...”

Voices: A Bird’s-Eye View of Climate Change. Here’s an excerpt from USA TODAY: “…Eight years later, the first prodigal puffin pair returned to roost. Things were looking pretty peachy for the puffins until waters in the Gulf of Maine began rising faster than 99% of all the Earth’s oceans, according to models by the National Oceanic and Atmospheric Administration, and throwing delicate fish populations out of whack. Audubon’s annual Christmas bird count reveals nearly 350 North American birds are “climate-affected,” living farther north. “For those species that are already farther north, they’ve got nowhere to go,” Kress says. “Their fate, their future, really is in our hands…”
CO2 Can Be Stored Underground for 10 Times the Length Needed to Avoid Climatic Impact: Study. Yes, but can carbon capture be done, at scale, cost-effectively? Here’s the intro to a story at phys.org: “Study of natural-occurring 100,000 year-old CO2 reservoirs shows no significant corroding of “cap rock”, suggesting the greenhouse gas hasn’t leaked back out – one of the main concerns with greenhouse gas reduction proposal of carbon capture and storage. New research shows that natural accumulations of carbon dioxide (CO2) that have been trapped underground for around 100,000 years have not significantly corroded the rocks above, suggesting that storing CO2 in reservoirs deep underground is much safer and more predictable over long periods of time than previously thought…”

Climate Change Risk Threatens 18 U.S. Military Sites: Study. Here’s the intro to a story at Reuters: “Rising sea levels due to hurricanes and tidal flooding intensified by climate change will put military bases along the U.S. East Coast and Gulf Coast at risk, according to a report released on Wednesday. Nonprofit group the Union of Concerned Scientists analyzed 18 military installations that represent more than 120 coastal bases nationwide to weigh the impact of climate change on their operations. Faster rates of sea level rises in the second half of this century could mean that tidal flooding will become a daily occurrence for some installations, pushing useable land needed for military training and testing into tidal zones, said the report titled “The U.S. Military on the Front Lines of Rising Seas…”

Tacked on to defense spending bills passed by the House of Representatives: amendments forbidding the Pentagon from using federal dollars to study climate change or plan for its impacts. Supporters say they want the military focused on enemies such as the Islamic State group, not rising seas. Critics say flooding is a formidable foe as well. “It’s kind of hard to attack the enemy when your base is underwater,” said Rep. Bobby Scott, a Southeast Virginia Democrat who voted against the ban. Exactly how far underwater depends on a range of factors, says the report, which paints scenarios similar to those predicted in studies conducted by the Army Corps of Engineers and others...”
Scientists Caught Off-Guard by Record Temperatures Linked to Climate Change. Thomson Reuters Foundation has the story: “Record temperatures in the first half of 2016 have taken scientists by surprise despite widespread recognition that extreme weather events are becoming more frequent and intense, the director of the World Climate Research Programme said. The earth is on track for its hottest year on record with June marking the 14th straight month of record heat, the World Meteorological Organization (WMO) said last week. Temperatures recorded mainly in the northern hemisphere in the first six months of the year, coupled with an early and fast Arctic sea ice melt and “new highs” in heat-trapping carbon dioxide levels, point to quickening climate change, it said…”
A Stunning Prediction of Climate Science – and Basic Physics – May Now Be Coming True. The Washington Post reports: “A lot of people deny climate change. Not many, though, deny gravity. That’s why a recent animation released by NASA’s Jet Propulsion Laboratory — well, it came out in April, but people seem to be noticing it now — is so striking. Because it suggests the likely gravitational imprint of our changing climate on key features of the Earth in a way that’s truly startling. The animation uses measurements from NASA’s squadron of GRACE satellites (Gravity Recovery and Climate Experiment), which detect changes in mass below them as they fly over the Earth, to calculate how the ocean changed from April 2002 until July 2013, based on corresponding changes in the mass of the continents…”
