No, Meteorologists Don't Study Meteorites
For a "media-rologist" the worst fear is anonymity. "Maul Muglas? I'm sorry. Never heard of you. Please go away." For the better part of a generation I've heard: "You hype the weather for ratings!".
Uh no. But I'd rather be accused of hype than missing a big storm altogether, and having to answer "Paul, why was there no warning?" As a profession we tend to err on the side of caution and paranoia.
Meteorologists study "meteors", defined as anything in the air: hydrometeors (clouds), electrometeors (thunder & lightning) and luminous meteors (rainbows and coronas). But not the shooting star kind.
I'm handcuffed to the Doppler again today; a line of strong to severe T-storms may flare up along the leading edge of temporary relief. Dew points drop back into the 50s Friday and Saturday. Good sleeping weather! Weekend weather looks very nice with ample sunshine, reasonable humidity levels and highs near 80; just a slight chance of thunder south of MSP Sunday afternoon. 80s return next week but more free A/C from Canada may arrive by mid-August.
No extended streak of 90s brewing. For now.
Comfortable Weekend. ECWMF guidance shows a cooling trend - by this time tomorrow dew points drop into the 50s, meaning roughly half as much water in the air. Warm, sticky air returns next week, so enjoy the break. Graphic: WeatherBell.
Ripe for T-storms. NOAA's 4km NAM brings a band of heavy T-storms across the Dakotas into Minnesota this morning; another wave of strong to severe T-storms may fire up again this afternoon. Future Radar product: AerisWeather.
Slight Severe Storm Risk. According to NOAA SPC the best chance of 1"+ hail and wind gusts > 58 mph will comes just south and east of the Twin Cities; a better chance of warnings from southeastern Minnesota into Wisconsin.
Lingering Heat Wave. The core of the ridge axis remains pasted over the southern USA, stretching from California to the central and southern Plains and southeastern USA. We'll see a few waves of heat, but I don't see persistent (obnoxious) 90-degree heat, day after day of misery, for Minnesota and Wisconsin looking out into the third week of August.
Is The Heat Index Real? The short answer is yes. More context from Mental Floss: "...The heat index is the temperature it feels like to your body when you factor in both the actual air temperature and the amount of moisture in the air. If the heat index is 103°F, that means that the combination of heat and humidity has a similar physical impact on your body as it would if the actual air temperature were 103°F. Even though it’s tempting to think of the heat index as an exaggerated temperature that only exists to make the heat sound worse than it really is, scientists came up with the measurements after decades of medical and meteorological research devoted to studying the impact of heat and humidity on the human body. It’s the real deal..."
Major Changes For 3 U.S. Weather Models Are Coming. Here's the intro to a story from Dr. Marshall Shepherd at Forbes: "The National Oceanic and Atmospheric Administration (NOAA) announced that major changes are coming to three of its weather prediction models. To the weather community and enthusiasts this is a big deal. However these changes also have impacts for a society which depends on weather forecasts for day-to-day operations, agriculture, aviation, national security, emergency response and more..."

Countries Are Spending Millions to Control the Weather. Here's Why. Yahoo News has an interesting story and background: "This summer, China set aside $30 million for a controversial project that involves shooting salt-and-mineral-filled bullets into the sky. Their mission? Make it rain. The project is part of a larger campaign of so-called weather modification techniques that the country has been using since at least 2008, when they claim to have cleared the skies for the Beijing Olympics by forcing the rain to come early. China is far from the only nation trying to bring (or stop) the rain. At least 52 countries — including the United States — have current weather modification programs, 10 more countries than five years ago, according to the World Meteorological Organization..."
Weather Disasters Can Fuel War in Volatile Countries. Scientific American has the story - here's an excerpt: "Following the warmest two years on record and spikes in violence that fueled a global refugee crisis, climate scientists on Monday reported that armed fighting is prone to follow droughts, heatwaves and other weather-related calamities in turbulent countries. Nearly a quarter of deadly armed conflicts in the countries with the most diverse ethnic makeups from 1980 to 2010 were found to have occurred at around the same time as an extreme weather event. “It’s significant that you can make that statement—that nearly 25 percent of those conflicts coincided with some type of climate-related disaster,” said Jonathan Donges, a Potsdam Institute for Climate Impact Research scientist who helped lead the new study..."

Planning for Disaster. Jacobin Magazine has an interesting post focused on the fairest, most equitable way of paying for the treadmill of disasters, current and future. Here's a clip: "...But when its eventual effects come to batter our door they will arrive at an exact address: floods and heat waves are intensely local disasters, and their history tells us that we are very much not in it together. Anywhere they strike the poorest residents are often hurt the most, lacking both the resources to rebuild and the protections that accrue to richer areas. If billions are being committed to fighting the effects of climate change, we should rightly be asking where they’re going, and who benefits. And we should ask now because the ball is already moving on local adaptation projects..."

Evacuate or Stay? Technology is lulling us into a false sense of security when it comes to hurricanes. "Hey, I can see them coming satellite and radar - if it looks bad we can head inland at the last minute." Maybe not. Here's an excerpt of an excellent article at Medium: "...In all disasters, knowing when, where, and how to escape is key, which brings us to the hurricane problem. Hurricanes are survivable events. They don’t strike out of nowhere. We have a battalion of satellites, buoys, and airplanes to track their every move from their infancy over the sea to their kamikaze-like demise along our coastlines. Forecasters man 24-hour weather offices that, in most cases, give days of warning of an impending storm. Yet some 2,000 people have died, either directly or indirectly, from hurricanes in modern, 21st century-America..."

Our Consumption of Earth's Natural Resources Has More Than Tripled in 40 Years. What would sustainable markets, sustainable capitalism look like? Huffington Post has the details: "Limestone and steel for our homes, wheat and vegetables for our dinner, fossil fuels for our industries: we rely heavily on our planet’s natural resources to survive. Yet we’re using up these resources at such an unsustainable pace that we may be “irreversibly” depleting some of them ― and critically damaging our Earth in the process, according to a new United Nations report. The report from the International Resource Panel, part of the UN Environment Program, said extraction of primary materials has more than tripled in 40 years. Rising consumption driven by a rapidly growing middle class is fueling the rate..." (Image credit: NASA).
Charging Pads Let Electric Car Owners Cut the Cord. A story at The Detroit News made me do a double-take: "Electric-vehicle charging cords could soon go the way of the cassette tape, floppy disk and landline telephone. Suppliers like Qualcomm Inc. and a handful of after-market companies offer wireless charging that requires no cords or physical contact. Some automakers are beginning to implement it on their fleets, although it will likely first be available mostly on high-end luxury makes. Mercedes-Benz, for example, will offer wireless charging on its S550e plug-in hybrid next year..."

Nuclear Power and Renewables Don't Have To Be Enemies. New York Just Showed How. Here's a clip from an explainer at Vox: "Consider, if you will, two basic facts about clean energy in the United States. Nuclear power is the country’s largest source of carbon-free energy, supplying about 19 percent of our electricity, but it’s barely growing. Wind and solar are smaller, at about 8 percent, but they’re growing much more rapidly. Put those together, and you get an intuitive blueprint for reducing US carbon dioxide emissions: Protect the nuclear base, and then scale up wind and solar on top of that, displacing fossil fuels as you go. Seems reasonable, no?..." (Image credit: Shutterstock).
LED Lighting Miracle: "One of the Fastest Technology Shifts in Human History." ThinkProgress has details: "...The rapid adoption of LEDs in lighting marks one of the fastest technology shifts in human history,” Goldman Sachs stated in a new report. The accelerated deployment of light-emitting diode (LED) bulbs is on track to save U.S. consumers and businesses $20 billion a year in electricity costs within a decade, which would lower U.S. CO2 emissions by some 100 million metric tons a year! The growing global effort to speed up LED adoption could ultimately cut global energy costs and carbon pollution 5 times as much..."

Skydiver Surfs Thunderstorm. Words I've never seen in the same sentence. The Facebook video from Tech Insider says: "Watch an insane skydiver surf the edge of a thunderstorm." You have to see it to believe it.
Stranger Things. Part X-Files, part Twilight Zone, part Happy Days (it's set in 1983) "Stranger Things" is oddly addictive. It's very well done, impressively creepy - you'll be hooked on Netflix's latest hit series after Episode 2.

Zillow Says Climate Change Could Leave 2 Million U.S. Homes Underwater - Literally. GeekWire has the story; here's the intro: "The U.S. housing market is finally recovering from the Great Recession — but now comes the tide of an equally insidious threat: Climate change. New Zillow research shows that unchecked climate change could leave 1.9 million homes underwater by 2100. Underwater, in this case, does not refer to negative equity. If sea levels rise by the estimated six feet in 85 years, about two percent of U.S. homes are at risk of being submerged. Those properties are worth a total $882 billion, according to Zillow...."

The 10 Most Startling Facts About Climate in 2015 - The Warmest Year on Record. Jason Samenow looks at the data and trends at Capital Weather Gang: "Last year was unequivocally the warmest year on record for Earth. The National Oceanic and Atmospheric Administration Tuesday released a 300-page report documenting the historic warmth as well as scores of other aspects of 2015’s climate. The hefty report, State of the Climate in 2015, was produced by more than 450 scientists from 62 countries around the world — more than any previous edition. Every single direct indicator of temperature described in the report leaves no doubt that 2015’s global surface temperature towered over any year preceding it. Numerous other climate indicators related to temperature exhibited characteristics consistent with such historic warmth..."

2015 Set Frenzy of Climate Records. Andrea Thompson has more perspective at Climate Central: "The report, now in its 26th year and published as a special edition of the journal Bulletin of the American Meteorological Society, was put together by 456 authors in 62 countries and provides a checkup of Earth’s health. “We have to understand how the planet is changing and varying . . . in order to understand where we may be going in the future,” Thomas Karl, director of NOAA’s National Centers for Environmental Information, said during a press teleconference. While a strong El Niño provided a boost to global temperatures last year, the main driver of the planet’s temperature surge, as well as other climate trends, is the warming caused by the buildup of greenhouse gases in the atmosphere. And just as many of the records of 2015 broke those set only one year earlier, 2016 has broken or is poised to break several of 2015’s records..."

Fewer Americans Doubt Climate Change - But Confidence Is Up On Both Sides. CSMonitor.com has the latest findings: "Two-thirds of all Americans are confident that climate change is real, and well-supported by evidence, according to a new National Survey on Energy and Environment (NSEE), a twice-yearly study from the University of Michigan and Muhlenberg College in Pennsylvania. Meanwhile, the number of respondents who say there is no solid evidence of global warming is at a record low: just 15 percent, versus 24 percent one year ago. The NSEE has been measuring public opinion on climate change since 2008, when 72 percent of respondents said global warming was a reality..."
Documenting Glaciers In The Dying Days of Ice. You might want to see Glacier National Park while there are still glaciers to see. Here's the intro to a photo essay from Climate Central: "National Parks have grown up with photography. So it’s only fitting that in the last days of ice in Montana’s Glacier National Park, Lisa McKeon is using a camera to show how quickly climate change has killed off the park’s namesakes. After all, it’s one thing to note that of the park’s 150 glaciers that existed in the late 1800s, only 25 of them remain today. But it’s another to see what that cold, hard fact looks like on the landscape..."

Conservatives Must Embrace The Fight Against Climate Change. Here's an excerpt of an Op-Ed at TheHill that resonated: "...In my view, the main reason why most conservative politicians deny climate change is because they believe the issue is simply a front to grow government. Denying the problem of climate change is easier than debating solutions. Most of the solutions proposed thus far have involved imposing more red tape and stringent regulations. What these conservatives don’t realize is that they have an opportunity to boost their image, win votes, and promote free enterprise and libertarian policy solutions by tackling the climate change issue head on rather than ceding the issue to liberals who use climate change as a vehicle for big-government policies..."
How Climate Change Has Reemerged on the Campaign Trail. Here's a clip from Christian Science Monitor: "...Democratic nominee Hillary Clinton has moved left and made renewable energy a central part of her platform, while Republican candidate Donald Trump has gone dramatically in the opposite direction, expressing skepticism about human-caused climate change and promising to deregulate the fossil fuel industry and to reject both the Paris climate accord and President Obama’s Clean Power Plan. Yet what this election has revealed is not just bipartisanship, but splits within the parties themselves..."
Deadly Maryland Flood Part of Clear Global Warming-Related Pattern in Extreme Rainfall Events. Here's an excerpt from Andrew Freedman at Mashable: "...However, the deadly downpour is consistent with what one expects to occur more frequently and with greater intensity — and what is already occurring with greater regularity — in a warming climate. The 2014 National Climate Assessment, for example, found there was an increase of 71 percent in the heaviest precipitation events in the Northeast between 1958 and 2012. According to Steve Bowen, a meteorologist for the insurance company AonBenfield, there have been nine 1-in-1,000-year rainfall events in the U.S. since 2010 alone, including a deadly flooding event in West Virginia in June..."

Anthrax Spewing Zombie Deer Are the Least of Your Warming Planet Worries. Eric Roston explains at Bloomberg: "Climate change is like a box of chocolates. You never know what you’re going to get. In northern Russia, you get anthrax.Conditions that are melting Arctic permafrost there recently thawed the carcasses of deer felled by anthrax some 75 years ago, when World War II raged. Warmer temperatures then reactivated the infectious disease, which can survive in hibernation for decades. More than three dozen people have been hospitalized, half of them children, though with no confirmed cases. Making matters worse, a heatwave combined with the anthrax outbreak may have killed more than 1,200 deer. New ones..."

Child, 12, Died from Anthrax, As 9 Cases Confirmed of Deadly Disease. More perspective from Siberian Times: "...The boy, Denis, died on Saturday from the virulent intestinal form of anthrax after eating infected venison. His grandmother died a day earlier, but as yet the cause is not established. Eight other people are now confirmed to be suffering from anthrax, including three children, according to preliminary diagnoses in the outbreak on the Yamal Peninsula in northern Siberia. The dead boy was a member of a reindeer herding family. A total of 72 people are now in hospital, a rise of 32 since Friday, under close observation amid fears of a major outbreak. 41 of those hospitalised are children as Russia copes with a full scale health emergency above the polar circle which has also killed thousands of reindeer..."

Climate Change is Hell on Alaska's Formerly Frozen Highways. Bloomberg explains: "...For seven decades, the Alaska Highway has mesmerized adventure-seeking travelers. In one breathtaking stretch through the Yukon, glacier lakes and rivers snake through aspen forests and rugged mountains that climb into the clouds. In recent years, though, a new sight has been drawing motorists’ attention, too, one they can spot just a few feet from their cars’ tires. Bumps and cracks have scarred huge swathes of the road, with some fissures so deep a grown man can jump in and walk through them. Scientists say they’re the crystal-clear manifestation that permafrost -- slabs of ice and sediment just beneath the Earth’s surface in colder climes -- is thawing as global temperatures keep rising..."
