Trade-off: Longer Boating Season, More Mosquitoes
Is the glass half-empty or half-full? The world isn't ending, it's warming. That will ratchet up environmental threats, but help to spark new technologies and business opportunities.
I've gone on record with my extended outlook: Minnesota will make out better than many other states, including Florida, Texas, Arizona and California. We have water, and our climate is trending even wetter over time.
The local NWS reports the last 12 months have been the wettest on record (since 1837) in the Twin Cities, with 40.72 inches of rain.
Growing season and boating/golfing season is longer now, but so is mosquito season. According to climate guru Mark Seeley, skeeter season in Minneapolis "is more than thirty days longer today than it was in 1980."
Today should be the sunnier, drier, nicer day of the weekend with a few T-showers pushing into far western Minnesota. Sunday brings a better chance of a few hours of showers & storms. If anyone asks next weekend looks warmer with highs in the mid-80s.
Ignore the Back to School ads. There's plenty of summer left to enjoy. More skeeters too.
Mosquito Season in Minnesota 30 Days Longer Now Than in 1980. Details via climatologist Mark Seeley in an article at Yale Climate Connections: "...He says mosquitoes thrive in warm, wet conditions. A warm, early spring means mosquitoes have a chance to breed sooner, leading to more mosquitoes and, potentially, more disease. As the world warms, spring is arriving earlier and earlier. Seeley: “Something like 75 percent of the last 20 spring seasons we’ve had have come on extraordinarily early.” Intense rainfalls have also become more frequent. When the ground cannot absorb more water, standing pools provide mosquitoes with an ideal habitat and breeding ground. It all adds up to a long buggy summer. On average, the mosquito season in Minneapolis is more than thirty days longer today than it was in 1980..."
Wettest 12 Month Period on Record. The Twin Cities office of the National Weather Service tweeted this out yesterday. 40.72" precipitation (rain and melted snow) since August of 2016, making this the wettest 12-month period since 1837.
30-30 Rule. There's a pernicious, pervasive belief that technology will save us - from ourselves. I'm not so sure. Apps on smartphones are great, but no replacement for common sense. In recent years I've run into coaches who don't evacuate the ball field until and unless "they can see lightning". Thunder? Rain? No problem - let the kids play! That's risky, considering any rumble of thunder implies that lightning is nearby. Lightning can travel up to 10 miles, horizontally. And just because the rain has stopped doesn't mean the lightning risk has passed. It's smart to wait at least 30 minutes after the last thunderclap before heading back out onto the field. Remember the "30-30 Rule". There have been 12 lightning fatalities across the USA this year. It pays to be paranoid. (Photo credit: Mitch Dobrowner).
It Wasn't Even a Hurricane, But Heavy Rains Flooded New Orleans as Pumps Faltered. The Washington Post reports: "...Panic and rough memories have surfaced across New Orleans this week as residents cope with yet another reminder that parts of the city sit as much as seven feet below sea level. And even though U.S. taxpayers have spent nearly $15 billion rebuilding the city’s flood protections since 2005, few here are confident the fixes can keep the city dry for long. Unlike during Hurricane Katrina, the problem over the weekend wasn’t the 133 miles of levees and flood walls that protect New Orleans from the tidal surges of the Gulf of Mexico or Lake Pontchartrain, which hangs over the northern and eastern edge of the city. Instead, parts of New Orleans were underwater because the city’s hundreds of miles of drains and pumps couldn’t bail rainwater fast enough..."

Insurer: Miami Is More Vulnerable to Hurricanes Like Andrew. Here's an excerpt from a story at AP: "Almost 25 years have passed since a Category 5 hurricane struck south of Miami, and the city’s vulnerability to catastrophic storm damage has grown exponentially, according to a new insurance underwriters’ analysis. At the time, Hurricane Andrew was the most expensive natural disaster in U.S. history, causing more than $26 billion of damage in Florida’s most populous areas, including $15.5 billion in insurance payouts. Stringent building code enforcement followed in Miami, but so did population growth, coastal development and climate change. “Our concerns lie with the fact that even though we’ve made good changes, 25 years later you have a much larger population living in Florida, and people forget what can happen or they don’t know what could happen,” said Monica Ningen, chief property underwriter for the U.S. and Canada at Swiss Re..."

— At any given time, nearly one-eighth of the world’s land mass was in severe drought. That’s far higher than normal and “one of the worst years for drought,” said report co-author Robert Dunn of the United Kingdom Met Office.
— Extreme weather was everywhere. Giant downpours were up. Heat waves struck all over the globe, including a nasty one in India. Extreme weather contributed to a gigantic wildfire in Canada.
— Global sea level rose another quarter of an inch (3.4 millimeters) for the sixth straight year of record high sea levels.
— There were 93 tropical cyclones across the globe, 13 percent more than normal. That included Hurricane Matthew that killed about 1,000 people in Haiti.
— The world’s glaciers shrank — for the 37th year in a row — by an average of about 3 feet (1 meter)..."

The Secret to Office Happiness Isn't Working Less - It's Caring Less. A subtle, yet important distinction, according to the author at Quartz: "We live in an age of “total work.” It’s a term coined by the German philosopher Josef Pieper just after World War II—describing the process by which human beings are transformed into workers, and the entirety of life is then transformed into work. Work becomes total when all of human life is centered around it; when everything else is not just subordinate to, but in the service of work. Leisure, festivity, and play come to resemble work—and then straight-up become it. Even our co-circular habits play into total work. People work out, rest and relax, eat well, and remain in good health for the sake of being more productive. We believe in working on ourselves as well as on our relationships. We think of our days off in terms of getting things done. And we take a good day to be a day in which we were productive..."

New Studies and Catastrophes Give Climate Change Deniers a Lot to Deny. Here's a clip from a column entry at The Miami Herald: "Denial begins to look like psychosis. Just in the past week, a cascade of new findings and climate anomalies have added to the scientific consensus that we’re cooked. Miami in particular. We’re seeing wildfires in Greenland, for heaven’s sake. Famously soggy Seattle has just gone through a record 54 consecutive days (and counting) without rain. On Thursday, Arctic explorer Pen Hadow left Nome, Alaska, in a 50-foot sailboat intent on something unfathomable before the onset of global warming. He and his crew intend to sail through the melting ice pack to the very North Pole. “If we can produce a visual image of a sail boat at 90 degrees north I think that could become an iconic image of the challenge that the twenty-first century faces,” Hadow wrote in his blog. That image would nicely illustrate the National Climate Assessment draft report publicized this week by the New York Times. “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” noted the assessment, based on input by scientists from 13 different federal agencies..."

Sailing to the North Pole, Thanks to Global Warming. Here is an excerpt of an interview at NPR:
PEN HADOW: "We are not going to be able to carry on mindlessly taking whatever we want from the environment. And I think a lot of people are looking to this as a symbol for a new debate.
KWONG: Because if two sailboats can get there, a whole universe of economic activity opens up around shipping and fishing. Both Russia and Denmark have filed claims for the North Pole, and other countries want to expand their Arctic territory, too. Unlike the South Pole, the North Pole has no legal protections. Hadow wants to shine a spotlight on the vulnerability of this region by being the first to get there.
HADOW: It is a strange challenge and ambition indeed - working very hard to put together a project that you don't actually want to succeed...."

Yes, You Can Blame Climate Change for Extreme Weather. Not all extreme weather, but does a warmer (wetter) climate amplify heat, drought and rainfall rates? Yes. Connecting the dots with wildfires, hurricanes and severe local storms isn't nearly as clear-cut, at least not yet. Here's an excerpt from TIME.com: "...For years, careful climate scientists — and the politicians like Obama who listened to them — have avoided saying that any particular event was directly caused by climate change, even as they called for urgent action to address the issue. But researchers now say they can use a variety of approaches to show that climate change is all but certainly causing and worsening extreme weather events. A comprehensive new report from scientists at 13 federal agencies, published this week by the New York Times as it awaits review by the Trump administration, highlights the change in thinking. The scientists behind the report, leaders in their respective fields, say researchers can use statistical analysis, modeling and other methods to determine how much climate change increased the likelihood of a given event..."
