Relief (evidence mounts that a warmer atmosphere is spiking America’s heat)

102 F. high in the Twin Cities Friday.

84 F. average high for July 6.

87 F. high temperature on July 6, 2011.

+13.1 F. first 5 days of July running more than 13 degrees F. above average, ever day above 90.

16 days above 90 F. so far this year (average for an entire summer is 13).


240 all-time record highs, nationwide, in the last 2 weeks. By all-time I mean the hottest ever observed for that city.

42,678 warm weather records since January 1, nationwide.

Record Highs. NOAA reports over 2,000 record highs in the last week. For an interactive map from Ham Weather click here.


Extended Outlook: Hot Enough. No more 100-degree heat is in sight, but I suspect we’ll see highs near 90 from Wednesday through Saturday of next week. Map: NOAA CPC and Ham Weather.


European Solution. We cool off slightly in the coming days, highs in the 80s. But the mercury may be flirting with 90 by Wednesday, a few low 90s possible toward the end of next week. Dry weather should be the rule for most of next week.

“Summer of 2012: A Legacy of Heat”. Here is an excerpt from Dr. Mark Seeley’s weekly WeatherTalk blog: “July is continuing a 9-month trend of above normal temperatures in Minnesota. In the Twin Cities Metro Area we have already seen 16 days with daytime highs of 90 degrees F or greater, and 8 nights when the temperature never fell below 70 degrees F. On average (1981-2010) the Twin Cities records 13 days each year with daytime highs of 90 degrees F or greater, and 11 nights when the nighttime temperature does not fall below 70 degrees F. Temperatures are expected to cool next week, but still average somewhat above normal. Lower dewpoints will help freshen the air.”


Extended Outlook: More 90+ Days. Graph above courtesy of the UCS, the Union of Concerned Scientists. Between 1961 and 1990 MSP saw an average of 13 days/year above 90 F. In a low carbon emission scenario we may see 21 days above 90 through 2039. If we fail to put a price on carbon, and greenhouse gas pollutants continue to increase worldwide the Twin Cities could see as many as 47 days/year above 90 by mid-century.

Saturday Severe Risk. Cooler, Canadian air pushing south into a blazing 100-degree airmass will set off a few severe storms later today from Columbus to Philadelphia, Baltimore and Boston. Map: SPC.


Many people around the world are beginning to appreciate that climate change is under way, that it’s having consequences that are playing out in real time and, in the United States at least, we are seeing more and more examples of extreme weather and extreme climate-related events.” NOAA Chief Jane  Lubchenco

The climate models have predicted what we’ve now seen, which is a doubling in the rate at which we break all-time warmth records in the U.S. We’re breaking those records, over the past decade, at a rate of almost twice what we would expect from chance alone.” – from an article at Newsday below.

What we’re seeing really is a window into what global warming really looks like,” said Princeton University geosciences and international affairs professor Michael Oppenheimer. “It looks like heat. It looks like fires. It looks like this kind of environmental disasters.” – from an article at The Seattle Times.


No, our resurgent belief in global warming seems to be a function of the weather.  A separate Yale survey this spring found that 82 percent of Americans had personally experienced extreme weather or natural disasters in the past year. And 52 percent said they believed the weather had been getting worse overall in recent years, compared to just 22 percent who thought it had gotten better.” – from an article at slate.com.

“Department of Homeland Security Secretary Janet Napolitano, surveying wildfires in Colorado Springs earlier this week, remarked on the “pattern” evident in the weather. “You have to look at climate change over a period of years, not just one summer,” Napolitano said. “You could always have one abnormal summer. But when you see one after another after another then you can see, yeah, there’s a pattern here.” – excerpt from a story at The Hill.

Blast-Furnace Heat Continues. NOAA has issued Excessive Heat Warnings from Madison, Chicago and Detroit eastward to D.C, Philadelphia and most of New Jersey again today. Heat indices will range from 105-115 F. by afternoon.


Historic Derecho. Did global warming make last week’s historic “super-derecho” even more intense and damaging? The Washington Post’s meteorologist Jason Samenow takes a close look at the meteorological conditions leading up to this unprecedented wind storm below.

Current temperatures are significantly hotter than the 1930s. We saw the very significant impact on our country’s farms back then; the impacts now have the potential to be far more devastating. For instance, the drought in Texas last year cost over $5 billion. This is real money with real consequences. If we don’t take action, we will be having conditions worse than this on a regular basis.” – Dr. John Abraham, climate scientist at the University of St. Thomas

The National Oceanic and Atmospheric Administration says the past winter was the fourth-warmest on record in the United States. To top that, spring — which meteorologists define as the months of March, April and May — was the warmest since record-keeping began in 1895. If you don’t believe me or the scientists, ask a farmer whose planting seasons have gone awry.”

NASA’s Goddard Institute for Space Studies, which monitors global surface temperatures, reports that nine of the warmest 10 years on record have occurred since 2000. The warmest year of all was 2010; last year was only the ninth warmest, but global temperatures were still almost a full degree warmer than they were during the middle of the 20th century.” – from an Op Ed in The Miami Herald – details below.

5-Day Rainfall Forecast. The latest QPF predicts the heaviest rains (2-4″) from the parishes of Louisiana to Nashville and the Outer Banks of North Carolina, more heavy T-storms flaring up near Denver and Colorado Springs, helping firefighters get ahead of the flames, the worst in Colorado history.

Searing Sun And Drought Shrivel Corn In Midwest. Here’s a snippet from a New York Times article about a growing drought gripping the Midwest: “….Crop insurance agents and agricultural economists are watching closely, a few comparing the situation with the devastating drought of 1988, when corn yields shriveled significantly, while some farmers have begun alluding, unhappily, to the Dust Bowl of the 1930s. Far more is at stake in the coming pivotal days: with the brief, delicate phase of pollination imminent in many states, miles and miles of corn will rise or fall on whether rain soon appears and temperatures moderate. “It all quickly went from ideal to tragic,” said Don Duvall, a farmer in Illinois who, in what was a virtually rainless June, has watched two of his cornfields dry up and die as others remain in some uncertain in-between.”

Colorado Wildfire Photos: The Waldo Canyon Fire in Colorado Springs. The Denver Post has a remarkable photo essay, including some of the most amazing (and heart-breaking) photos I’ve ever seen, related to wildfires. A tornado risk is one thing – but can you imagine a 5 mile wide wall of flames, 100 feet high, approaching your home at 40 mph? “A three-day-old wildfire erupted with catastrophic fury Tuesday, ripping across the foothills neighborhoods of Colorado Springs, devouring an untold number of homes and sending tens of thousands fleeing to safety in what was shaping up as one of the biggest disasters in state history. “This is a firestorm of epic proportions,” said Colorado Springs Fire Chief Richard Brown. The Waldo Canyon fire in El Paso County — which had been growing in the forested hills on the city’s west side — blew into an inferno late in the afternoon, raging over a ridge toward densely populated neighborhoods.”

Photo credit above: “The Waldo Canyon fire burns an entire neighborhood in near the foothills of Colorado Springs, Colo. Tuesday, June 26, 2012. Colorado has endured nearly a week of 100-plus-degree days and low humidity, sapping moisture from timber and grass, creating a devastating formula for volatile wildfires across the state and punishing conditions for firefighters.” (The Denver Post, Helen H. Richardson)


Colorado’s Perfect Firestorm. Here’s a snippet of an extraordinary article at The Los Angeles Times, trying to put the recent Colorado fires into some sort of long-term historical perspective: “Last week, my parents had to pack their belongings and flee as the Waldo Canyon fire barreled toward their house in Colorado Springs. They were among 32,000 people forced from their houses by the fire, which has destroyed nearly 350 homes. My parents were lucky. Despite the trauma and fear of having to evacuate, they didn’t lose their home. But the fire emphasized something of a long-running debate between my father and me: the reality and politics of climate change. I am a political scientist who studies climate policy and adaptation, and the intersection between climate science and politics. My father is also a scientist — a nuclear engineer. But he’s always been a bit skeptical about climate change. Though he’s not a full-on doubter, he also hasn’t fully embraced the idea that the planet is warming in ways that could be devastating, and that this change is the result of human activity. Events like the Waldo Canyon fire may make him and other climate skeptics easier to convince.”



Derecho In D.C.: Science And Surprise. Here is a comprehensive look at the “super-derecho” that tracked nearly 800 miles, whipping up straight-line winds over 90 mph at times, knocking out power to millions of Americans. There was only a few hours advance-warning. What are these freak storms, how and why do they form? Why are computer models often ineffective predicting these swirling, boomerang-shaped swarms of severe storms? Some answers from NCAR/UCAR AtmosNews: “With a ferocity to match the record heat it displaced, a thunderstorm complex raced from Illinois to the Delaware coast in a mere 12 hours on Friday evening, June 29. It knocked down countless trees and power lines, with wind gusts topping 80 miles per hour in many spots. It threw millions of people into turmoil, with air conditioners, computers, and phones out for days. And it brought to light a weather word du jour with an obscure but intriguing history… By morning, though, the signals were starting to come together in data from radiosondes (weather balloons) and forecasts from weather models, which increasingly pointed toward a storm complex moving from the Midwest toward the Appalachians. Derechos seldom cross the Appalachians intact, which keeps D.C.-area forecasters cautious about forecasting such a leap. Indeed, a storm complex that produced 80 to 90 mph winds in Chicago on Sunday, 1 July, fizzled en route. But on June 29, the extreme warmth and depth of the air mass, plus energy from the jet stream, kept the derecho powerful all the way to the Atlantic Ocean.”

Did Global Warming Intensify The Derecho In Washington D.C.? Here’s an excerpt of a fascinating article from meteorologist Jason Samenow at The Washington Post’s Capital Weather Gang, attempting to connect the dots between supercharged heat/humidity and the subsequent super-derecho that struck with little warning: “The June 29 derecho, which caused widespread damage in Washington, D.C. blossomed to full fury in a record hot environment. Could the heat added to the atmosphere from manmade greenhouse gases have provided extra fuel to this explosive storm? The amount of energy available to this storm was extreme and, wundergound weather historian Chris Burt called the number of all-time heat records set around the time “especially extraordinary.” But as I wrote the day after the storm, connecting global warming to the derecho is a complicated and controversial question.”

Will Microsoft Redefine The Industry With Windows 8 And The Surface Pro? At first blush it looks pretty impressive – I’m keeping an open mind (in spite of my love for all-things-Apple). More from gizmag.com: “Windows 8 represents a big change for Microsoft’s industry leading OS. It breaks from tradition by doing away with the long serving Start button and replacing it with a tile-based and touch-friendly Metro UI. While this move has widely polarized opinion, especially in the enterprise sector, it does represent a major trend across the industry, with mobile-tablet operating systems becoming more and more closely related to their laptop and desktop counterparts. This trend is personified by Microsoft’s in-house tablet, the Surface Pro.”


GoVacuum’s $1 Million Gold-Plated Vacuum Cleaner. Just when you thought you’d seen everything – along comes this blurb from the amazing techno-geeks at gizmag.com. You just can’t make this stuff up; here’s an excerpt: “Every now and then, we here at Gizmag like to take a look at how the other half (or one percent) live. And why not? It’s nice to occasionally fantasize about say, waking up in a private, underwater hotel room, to be chauffeured in a Mercedes-Benz to a weekend getaway on your own personal floating island. But does that fantasy involve personalized, gold-plated cleaning appliances? If it didn’t before, it sure can now with GoVacuum’s GV62711 vacuum cleaner and it’s US$1 million price tag.”

What Vacation?
We’re all wired now, continuously plugged into The Matrix; a never-ending treadmill of e-mails, texts and action items. But meteorologists never (ever) get a break. “Honey, what time will the rain stop?” my wife demanded. 2:32 pm, I replied. Nothing like a little sarcasm to brighten up a 28 year marriage. “Will the front pass in time for fireworks? What time will the sun come out? Why is it still raining? You said it would be over by now!” So here I sit, my face buried in the Doppler, praying (out loud) for a break. Yes, I know it comes with the turf.
But we’re all weather-weary now. If you’re sick of Heat Warnings, Super-Derechos and dew-point-babble raise your hand. I’m waving my little white flag. I surrender.
Suffocating heat is over; a nagging frontal boundary sparks more T-storms today. Not an all-day washout, but a few hours of puddles, with a fresh north breeze and highs near 80. A C- Saturday. Sunday gets a B+ on my lop-sided grading scale; more sun – highs in the mid 80s. Each day gets sunnier and warmer next week; another run at 90+ the latter half of next week.
Red blobs on Doppler? Uh oh. My wife won’t be pleased.
I need a vacation from my vacation.

Climate Stories…


“Bad Weather Or Global Warming?” Here’s an excerpt of an Op-Ed at Newsday on Long Island: “Swaths of the country have been enduring day upon day of triple- and near-triple-digit temperatures, so it might be hard to remember that just two years ago, when Washington, D.C., was blanketed in record snowfall, noted climate change skeptic Sen. James Inhofe (R-Okla.) and his family were building an igloo on the national mall to mock former vice president and leading environmentalist Al Gore. That winter, Matt Drudge and Rush Limbaugh gleefully noted that a Senate conference on climate change had to be canceled due to snow. Scientists and environmentalists pointed out at the time that a record snowfall is in no way inconsistent with a warming planet — in fact, many models predict that heavy snow could become more common because a warmer atmosphere will hold more water vapor. But the larger point is that, as Jane Lubchenco, the head of the National Oceanic and Atmospheric Administration (NOAA), put it in 2010, “It is important that people recognize that weather is not the same thing as climate.” Large variations in temperature and humidity will occur even as global temperatures rise.”

Graphic credit above: Photo credit: Donna Grethen/Tribune Media Services. “More than 2,000 U.S. heat records were broken just in the past week. Some climatologists argue that while there’s certainly nothing unexpected in periodic record-breaking temperatures, the rate at which these records are being broken year after year can’t be explained away by coincidence.”


Climate Change Belief Increased In U.S. After Extreme Weather, NOAA Chief Says. Here’s an excerpt from Huffington Post: “….Many Americans had previously seen climate change as a “nebulous concept” removed from them in time and geography, said National Oceanic and Atmospheric Administration chief Jane Lubchenco. “Many people around the world are beginning to appreciate that climate change is under way, that it’s having consequences that are playing out in real time and, in the United States at least, we are seeing more and more examples of extreme weather and extreme climate-related events,” Lubchenco told a university forum in the Australian capital of Canberra.”


Heat Wave, Fires Have Climate Change Activists Going On The Offensive. Here’s an excerpt from The Hill: “…Still, Weiss said the extreme weather “will put the heat on legislators who want to block action to address climate change.” “Since so many members of the Senate and House Republican caucuses are climate science deniers, it is unclear whether that element will change, but at least for members who are sort of moderate conservatives, who in the past have tried to block carbon pollution reductions, this should be a giant wake-up call that time is growing short to act,” said Weiss, who directs his group’s climate strategy. Growing campaigns around extreme weather would mark at least a subtle shift in messaging for the environmental movement, which in recent years has focused heavily on emphasizing what they call the economic benefits of a shift to low-carbon energy sources.”


Global Warming Is Shrinking Plants: Study. Here’s an excerpt of a story at The Bunsen Burner: “For the first time, scientists have begun study the effects of global warming on plant species morphology. University of Adelaide researchers have found that some Australian plants are narrowing their leaves in response to changes in climate. Lead author of the paper, Dr. Greg Guerin, says, “Climate change is often discussed in terms of future impacts, but changes in temperature over recent decades have already been ecologically significant.” Scientists gathered historical and contemporary specimens from the State herbarium, some dating back to the 1880’s. Focusing on narrow-leaf Hopbushes from Flinder’s Range, the largest mountain range in Southern Australia, research concluded that “leaf width…was negatively correlated with latitude regionally, and leaf area was negatively correlated with altitude locally.“ Researchers predicted, “…given within-species variation along a climate gradient, a morphological shift should have occurred over time due to climate change.” Image above: NASA.

Climate Change: “This Is Just The Beginning”. Here’s an excerpt of an article from Amy Goodman at truthdig.com: “Evidence supporting the existence of climate change is pummeling the United States this summer, from the mountain wildfires of Colorado to the recent “derecho” storm that left at least 23 dead and 1.4 million people without power from Illinois to Virginia. The phrase “extreme weather” flashes across television screens from coast to coast, but its connection to climate change is consistently ignored, if not outright mocked. If our news media, including—or especially—the meteorologists, continue to ignore the essential link between extreme weather and climate change, then we as a nation, the greatest per capita polluters on the planet, may not act in time to avert even greater catastrophe.”

Feeling The Heat Yet? Here’s an excerpt of an Op-Ed in The Miami Herald: “Still don’t believe in climate change? Then you’re either deep in denial or delirious from the heat.As I write this, the nation’s capital and its suburbs are in post-apocalypse mode. About one-fourth of all households have no electricity, the legacy of an unprecedented assault by violent thunderstorms Friday night. Things are improving: At the height of the power outage, nearly half the region was dark. The line of storms, which killed at least 17 people as it raced from the Midwest to the sea, culminated a punishing day when the official temperature here reached 104 degrees, a record for June. Hurricane-force winds of up to 80 miles per hour wreaked havoc with the lush tree canopy that is perhaps Washington’s most glorious amenity. One of my neighbors was lucky when a huge branch, headed for his roof, got snagged by a power line. Another neighbor lost a tree that fell into another tree that smashed an adjacent house, demolishing the second floor.”

Temperature Trends: Contiguous USA. Data from NOAA NCDC – temperatures for 2012 are 4-5 F. warmer than the long-term average, on track to be the warmest year on record. 9 of the 10 warmest years on record have taken place since 2000.

On The Media: Finally Seeing The Link Between Climate Change, Disasters? The story from NRDC and Bob Keefe at Huffington Post: “The media just might be starting to see the obvious link between climate change and extreme weather. Of course it’s hard to miss during a week or so when we have deluges in Florida, wildfires in Colorado and deadly freak storms in Washington D.C. and elsewhere along the Eastern Seaboard. Scientists suggest taking a look at U.S. weather in recent weeks.” Over in the new media world, Yahoo is carrying a story called “What’s Behind the Record Heat?” The answer: it could be “a hallmark of a warming planet.”

Climate Change Is Already Shrinking Crop Yields. Here’s some bad news for farmers, an excerpt of a story from Mother Jones: “For years now, people have wondered how climate change will affect farming. How will humanity feed itself during a time of rising temperatures and recurring drought? Here in the US, we’re starting to get a taste of things to come—and it’s bitter. Brutal heat is now roiling the main growing regions for corn, soy, and wheat, the biggest US crops. According to Bloomberg News, 71 percent of the Midwest is experiencing “drier-than-normal conditions,” and temperatures are projected to be above 90 degrees in large swaths of key corn/soy-growing states Missouri, Illinois, and Indiana through July 7 if not longer.”

Climate Change Understanding Rebounds to 2009 Levels. Here’s more from Think Progress: “Over a short period at the start of 2010, belief that climate change is real and manmade fell sharply. Since then, it recovered slightly but had remained lower than it was at the end of 2009. But now three polls have shown that the decline has been fully reversed.”

Climate Change: Forest Warming Forces Warming. Here’s a clip from a story at Great Lakes Echo: “A rise of global temperatures will release more carbon dioxide from forest soils, according to a new study that includes a look at a Wisconsin forest. And that increased release of the greenhouse gas could make the climate heat yet even faster. Scientists at the University of the California Irvine heated by 10 to 20 degrees soil collected from forests in Wisconsin and North Carolina. They discovered that the warming released up to eight times more carbon dioxide. The study was published June 11 in the online edition of the Proceedings of the National Academy of Sciences journal.”
