“TRMM’s Precipitation Radar (PR) data show a 3-D view of Daniel (looking from the west). This view shows that very little rainfall was present in the western side. This image also shows that most of Daniels structure was at lower levels. A few of the most powerful storms in the eastern side of Daniel’s eye wall reached to heights of about 11km (~6.8 miles).

Active Eastern Pacific
Daniel and Emilia, seen below, continue to churn westward. The latest forecast from the National Hurricane Center has remnants from Daniel sliding just south of Hawaii by the weekend.
Note the orange hatched circle below, that is a cluster of thunderstorms that has a medium chance of becoming our next named storm. If it does grow into Tropical Storm strength, Fabio its name!
1. CLOUDINESS AND SHOWERS ASSOCIATED WITH A BROAD LOW PRESSURE SYSTEM LOCATED SEVERAL HUNDRED MILES SOUTH OF ACAPULCO MEXICO HAVE CHANGED LITTLE IN ORGANIZATION OVER THE PAST SEVERAL HOURS. CONDITIONS APPEAR CONDUCIVE FOR SLOW DEVELOPMENT OF THIS DISTURBANCE OVER THE NEXT FEW DAYS AS IT MOVES WEST-NORTHWESTWARD NEAR 10 MPH. THIS SYSTEM HAS A MEDIUM CHANCE…40 PERCENT…OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
Significant June Events
“Climate Highlights — June
The average temperature for the contiguous U.S. during June was 71.2°F, which is 2.0°F above the 20th century average. The June temperatures contributed to a record-warm first half of the year and the warmest 12-month period the nation has experienced since recordkeeping began in 1895. Scorching temperatures during the second half of the month led many cities to set all-time temperature records.
Precipitation totals across the country were mixed during June. The nation, as a whole, experienced its tenth driest June on record, with a nationally-averaged precipitation total of 2.27 inches, 0.62 inch below average. Record and near-record dry conditions were present across the Intermountain West, while Tropical Storm Debby dropped record precipitation across Florida.”
The January-June period was the warmest first half of any year on record for the contiguous United States. The national temperature of 52.9°F was 4.5°F above average. Most of the contiguous U.S. was record and near-record warm for the six-month period, except the Pacific Northwest. Twenty-eight states east of the Rockies were record warm and an additional 15 states were top ten warm.
The first six months of 2012 were also drier than average for much of the contiguous U.S., with a nationally-averaged precipitation total 1.62 inches below average. Drier-than-average conditions stretched from the West, through the Central Plains, into the Ohio Valley and Mid-Atlantic. Fourteen states in total had precipitation totals for the six-month period among their ten driest.”
12 Month Period Climate Highlights
“Climate Highlights — 12-month period (July 2011-June 2012)
The July 2011-June 2012 period was the warmest 12-month period of any 12-months on record for the contiguous U.S., narrowly surpassing the record broken last month for the June 2011-May 2012 period by 0.05°F. The nationally-averaged temperature of 56.0°F was 3.2°F above the long term average. Every state across the contiguous U.S. had warmer than average temperatures for the period, except Washington, which was near normal.”
99th Anniversary of the 134F High Temp in Death Valley, CA
“Today marks the anniversary of when Death Valley, Calif. set the all-time record high for not just the United States, but also the Western Hemisphere.
Temperatures in Death Valley (at Greenland Ranch, which is now known as Furnace Creek Ranch) soared to 134 degrees on July 10, 1913.”
“At 86 meters (282 feet) below sea level, Death Valley, California, is one of the hottest, driest places on the planet. On average, the area sees only about 5 centimeters (1.96 inches) of rain a year, and summer temperatures routinely soar above 38 degrees Celsius (100 degrees Fahrenheit). At night, temperatures drop considerably, and many animals in Death Valley are nocturnal as a result. Plants and animals living in this punishing environment have had to adapt to extremes of temperature and aridity.
This image is compiled from observations by the Enhanced Thematic Mapper Plus sensor on the Landsat 7 satellite on June 11 and July 20, 2000. In this image, green indicates vegetation, which increases with altitude. The peaks of Death Valley National Park sport forests of juniper and pine. The dots of brilliant green near the right edge of the image fall outside park boundaries, and probably result from irrigation. On the floor of the valley, vegetation is sparse, yet more than 1,000 different species eke out an existence in the park, some of them sending roots many feet below ground. The varying shades of brown, beige and rust indicate bare ground; the different colors result from varying mineral compositions in the rocks and dirt. Although they appear to be pools of water, the bright blue-green patches in the scene are actually salt pans that hold only a little moisture.”
Death Valley, CA Forecast
The 7 Day forecast for a reporting station in Death Valley, CA is calling for some scorching temperatures today and tomorrow… in the 120s YIKES!!
“Earth’s deadliest flood of 2012 hit the Black Sea area of Russia on Saturday, where 300 mm (11.8″) of rain fell in less than 24 hours. The resulting flood waters swept through the town of Krymsk in the Krasnodar region early Saturday, killing at least 171 people. The heavy rains were caused by a low pressure system that tracked just north of the region. The counter-clockwise flow of air around the low brought moisture-laden air from the Black Sea northwards over the mountains bordering the Black Sea.”

Forecast Highs Today
These are the forecast high temperatures today, note the extreme heat in the Southwest.
Heavy Rain Forecast
NOAA’s HPC 5 day precipitation forecast shows considerable moisture potential from the Lower Mississippi Valley into the Ohio Valley through the weekend. The latest forecast suggests 3″ to 6″ in spots through early Sunday.
Rich gulf moisture continues to produce storms along the Gulf Coast. Cory Niblett (@PR3SIDENT_) snapped this photo of a waterspout this morning from the Fairhope Pier in Alabama.
Sunday, a microburst with 80mph westerly winds tore through an area 3 miles south of Fredericksburg injuring 7 people and causing serious damage. The injuries came inside a gym after the gym roof was blown off and a wall collapsed. Mark Elllinwood (YouTube: madusweather) has a look at some of the damage. Thank you for sharing with us. And you can read more about the storm and see more photos in his blog. Madusweather.com
What is a Microburst?
The National Weather Service defines a microburst as a downdraft (sinking air) in a thunderstorm that is less than 2.5 miles in scale. Although microbursts are not as widely recognized as tornadoes, they can cause comparable, and in some cases, worse damage than some tornadoes produce. In fact, wind speeds as high as 150 mph are possible in extreme microburst cases. The National Weather Service in Amarillo, Texas shared a great explanation after a microburst in that area last summer. Click here to read more.
Bay Scroggins took this awesome halo photo in Key Biscane, FL today. Halos can be seen when cirrus clouds composed of ice crystals form 3-6 miles up in the troposphere and are angled in such a way to reflect and refract light in a circle around the Sun. Halos can happen around the Sun or the Moon, and they make for spectacular photos.
Thanks for checking in on this Tuesday, have a great rest of your week!
2012: warmest first 6 months of any year on record. NOAA. Last 12 months: warmest 1-year period since 1895 across the USA (NOAA). 10 warmest 12-month periods on record (1895-present) all occurred since 2000. Source: NOAA. Hottest heat wave on record for Washington D.C. The scope and intensity of last week’s heat was even worse than 1930. Details from The Washington Post below.
50% According to a recent survey, nearly 50% of America’s weather reporters (including degreed meteorologists) “don’t believe in human-induced climate change.” More information from “Forecast The Facts”.
2,278 daily heat records broken or tied during the first week of July, nationwide. 3,282 daily heat records broken or tied during June across the USA. 173 of these were all-time highs. 9,800 daily heat records broken or tied during June, 1988. Source (and map above): Climate Central – details below.
Warmest 12 Month Period In USA – Drought Expands To 56% Of Nation. Here’s the latest from NOAA: “The average temperature for the contiguous U.S. during June was 71.2°F, 2.0°F above the 20th century average, ranking as the 14th warmest June on record. Scorching temperatures during the second half of the month broke or tied over 170 all-time temperature records in cities across America. June temperatures also contributed to a record-warm first half of the year and the warmest 12-month period the nation has experienced since recordkeeping began in 1895.”
Historic Heat Wave In Hindsight: Hottest On Record In Washington D.C., Hotter Than 1930. Here’s a fascinating article from Ian Livingston and Jason Samenow at The Washington Post. Comparing apples to apples can be tricky, but these two meteorologists took the time to analyze the data carefully – here’s an excerpt of the story: “The average high from June 28 through July 8, 2012 was an astounding 99.5 degrees, besting 1930’s most brutal 11-day stretch (the first big heat wave was 12 days long with a 95 to start) by 0.5 degrees. When considering the average temperature (incorporating low temperatures as well as highs) for these segments of both years, 2012’s lead grows due to warmer overnight temperatures. 2012 finished with an average temperature of 88.0 degrees compared to 1930’s 87.0 over the 11 days.”

2012 Heatwave Is Historic, If Not Unprecedented. Some perspective is in order – how does our recent heatwave rank with 1988 and the worst years of the Dust Bowl back in the 1930s? Meteorologist Andrew Freedman provides some fascinating details in thisClimate Central post; here’s an excerpt: “Now that the heat wave has finally subsided, we can begin to take stock of how unusual it really was. There is no question that it was extraordinary in its intensity and geographical scope for so early in the summer season. But was it unprecedented in American history? The short answer is no, it wasn’t unprecedented. The longer answer is that it will go down in history as one of the hottest and longest-lasting early summer heat waves in U.S. history, and by at least one measure, it was the record setter in every sense of the phrase. It was also a clear taste of what’s to come as the climate continues to warm due to manmade global warming.”

U.S. Corn Growers Farming In Hell As Midwest Heat Spreads. The drought is expanding across the Midwest and Ohio Valley – more from Bloomberg Businessweek: “The worst U.S. drought since Ronald Reagan was president is withering the world’s largest corn crop, and the speed of the damage may spur the government to make a record cut in its July estimate for domestic inventories. Tumbling yields will combine with the greatest-ever global demand to leave U.S. stockpiles on Sept. 1, 2013, at 1.216 billion bushels (30.89 million metric tons), according to the average of 31 analyst estimates compiled by Bloomberg. That’s 35 percent below the U.S. Department of Agriculture’s June 12 forecast, implying the biggest reduction since at least 1973. The USDA updates its harvest and inventory estimates July 11.”

“The drought is much worse than last year and approaching the 1988 disaster,” said John Cory, the chief executive officer of Rochester, Indiana-based grain processor Prairie Mills Products LLC. “There are crops that won’t make it. The dairy and livestock industries are going to get hit very hard. People are just beginning to realize the depth of the problem.” – from a Bloomberg Businessweek story on the spreading drought; more information below.
“An Oxfam report also notes that “this could be just a taste of things to come because in the next few decades the build-up of greenhouse gases already in the atmosphere could greatly increase the risk of droughts, flooding, pest infestation and water scarcity for agriculture systems already under tremendous stress.” – from a story on climate change impacting agriculture and food production from journalstar.com; details below.
“The U.S. Global Change Research Program recently concluded: “Human-induced climate change appears to be well underway in the Southwest.” It reported that in the West “both the frequency of large wildfires and the length of the fire season have increased substantially in recent decades, due primarily to earlier spring snowmelt and higher spring and summer temperatures.” – from a Huffington Post story on wildfires and climate change; details below.
USDA Reports Big Drop In Iowa Corn Conditions. Some troubling news for corn farmers from The Des Moines Register: “The U.S. Department of Agriculture said Monday that the percentage of Iowa’s corn crop rated good to excellent fell from 62 percent a week ago to 46 percent through Sunday as a week of 100-degree temperatures and no rainfall took its toll. A year ago 82 percent of Iowa’s corn crop was rated good to excellent. Nationally, just 40 percent of the corn crop was rated good to excellent, compared to 48 percent last week. Conditions were similar for soybeans. Iowa’s crop is rated 48 percent good to excellent, down from 59 percent last week and 80 percent this week last year. Nationally the crop was rated 38 percent good to excellent compared with 45 percent a week ago and 66 percent last year.”

Expanding Drought. Here is the latest from NOAA’s Drought Monitor; 52% of the Midwest in a moderate drought, nearly 25% of the 9-state area, up from 15% last week. Soil moisture across much of Minnesota is in fairly good shape (with the exception of the Red River Valley, but many counties over far southern Minnesota are still dry.
5-Day Rainfall Outlook. Heavy showers and T-storms are likely from Texas and the parishes of Louisiana to Nashville and Atlanta, some 3-6″ rainfall amounts. Meanwhile mostly-dry weather lingers for much of the Midwest and the far west. Map: NOAA HPC.
Severe Weather Intensifies Focus On Disaster Planning. A spike in severe storms is impacting the power grid, and may have implications for “the cloud”. Here’s an excerpt from Computer World: “Severe thunderstorms knocked out power to 1.2 million homes in the D.C. area. Wildfires ravaged more than 2 million acres in the Rockies. Two-thirds of the country is in drought conditions, and flooding is expected to get worse as the time between rainstorms lengthen and, in turn, grow more intense. Intensifying weather patterns threaten businesses as global warming raises the temperatures of the oceans. Disaster recovery plans that include only backing up data regionally may need to be rethought, experts say. The cloud, which was supposed to guarantee high availability, has been significantly affected by power outages caused by storms. Companies dependent on cloud service provider Amazon Web Services (AWS) found their websites down a week ago when rare severe thunderstorms, known as derechos, struck the Virginia and Washington D.C. area, leaving 1.2 million homes without power for days.”
St. Louis Foresters Say Deer Stands, Tree-Cutting And Food Plots Are Getting Out Of Hand On County Land. Here’s an excerpt from The Duluth News Tribune: “It used to be that a deer stand was a couple of aspen saplings nailed between two trees, just a place for a hunter to see above the brush for a better shot at a trophy buck. But increasingly across St. Louis County forests, including on public lands, permanent deer stands have become a whole lot more elaborate — some far too elaborate for county land managers. And hunters are cutting more trees near those stands so they can see deeper into the woods.”
Photo credit above: “This 20-by-18-foot deer “stand” was built on St. Louis County forestland. County land managers say they want to limit the size and nature of deer stands while banning the cutting of trees for shooting lanes and the planting of food plots.” (St. Louis County Department of Lands and Mines photo).
“Ask Paul”. Weather-related Q&A:
Paul,”I read your column with interest many mornings in the Strib. I have a deep concern for the environment believing in “creation care” from a Christian viewpoint. I have spent my career working for non-profits – currently am serving a large church in the NW metro – and have limited income but would love to spend some money to save money as well as cut down significantly my family’s energy use. But I do care and wonder what I can do? Do you have any website or local organizations that I can look into? Let me know if you have any thoughts for me. Appreciate your blog. I think it would be helpful to offer not only analysis – which is grim – but encouragement to take steps to change the future. One last question. I have a 9 year old who has a huge interest in the weather – mostly out of self preservation (she’s afraid of storms) – and she’s our weather watcher. Do you ever do introductory teachings on the weather or know how a 9 year old could get a tour or something? We’d love any ideas you have for us.”ThanksBrian Houts
Brain – thank you for your efforts. I’m a Christian too, and I take my role as a steward of creation seriously. There are some things you can do. Pick up a copy of “Cooler – Smarter” from the Union of Concerned Scientists for practical tips. A pdf sample is here. No, I don’t get a commission. Have a goal of reducing your carbon footprint by 20% Tell coworkers, friends and family what you’re doing, and why. We need a bottom-up approach. Although governments will ultimately put a price on carbon, true solutions will come from all of us, working together. I understand the reality: climate change is a depressing topic. There is no easy fix, no silver bullet. But there is plenty of (green) buckshot.
30 Ways To Foster Progress On A Finite Planet. Here’s an excerpt from an Andy Revkin, New York Times post, focused on steps we can all take to live more sustainably. The most important thing we can do: tell our legislators that this topic is important to you and your family. We need to find a market-friendly way of pricing carbon. All of us can take steps to lower our carbon footprint, from weatherizing our homes to driving a more fuel-efficient vehicle: “Orion Magazine, a beautiful and lyrical nonprofit publication, is celebrating its 30th anniversary by publishing “Thirty-Year Plan,” a short book of essays by 30 writers, myself included, who were asked to describe “some thing—emotion, insight, technology, resource, practice, policy, habit, attitude—that’s going to be increasingly essential if humans are going to live comfortably, sustainably, and redeemably on Earth.” (You can sift excerpts from the 30 essays in the Orion slide show above.)”
“That was an interesting piece that you reference (in Monday’s weather blog) about the Chicago weatherman inteverviewed on PBS. Not having seen the episode, and not knowing the meteorologists personally, the thought that came to my mind was that perhaps they aren’t allowed to talk about climate change as station policy (hmm, perhaps advertisers won’t accept it). Is there any other plausible explanation for the collective throwing up of their hands? Can they really not see any link between a heating climate and high-energy weather? I continue to appreciate your thoughtful, insightful and apparently courageous reporting.”Respectfully,
Of all the meteorologists in Chicago, the one I have the most respect for is Tom Skilling. To be fair, I don’t know his position (wrong word) on climate change. Tom is incredibly bright and well read, I can’t believe that he would deny the overwhelming body of science. But here’s the deal: local television has become a popularity contest. People watch their favorite anchors, reporters and, yes, meteorologists. Q Scores, a measure of popularity, are critical. On air talent is constantly researched. My previous employer shared bits and pieces of the research – it was pretty clear to me that by taking a stand on climate change I was alienating more conservative viewers.
Climate change is kryptonite for TV meteorologists. By even bringing up the topic you just know that you’re going to alienate some percentage of the audience, who still links AGW with Al Gore and “climategate” and conspiracy theories. In the back of our minds:ratings. If 2 out of 10, or maybe 4 out of 10 people are skeptical/resistant to this topic, why even bring it up and risk that…they won’t like me? That’s the calculus that goes through our minds. If the ratings go down, everyone looks for work. Why risk pissing people off? It’s easier sticking with safe topics, like dew point and hot weather survival tips. Easier to joke with the anchorman than bring up a topic that inspires a). dread, and b). rage.
I’m as skeptical as the next guy. In the 80s I thought James Hansen at NASA was over-hyping the role of climate change. But by the mid 90s I was seeing things on the weather maps that fell outside the normal swings of “weather” – stuff I couldn’t explain. More intense rains, more hail, fickle winters, higher summer humidities, far fewer arctic outbreaks. I respond to data, and the facts on the ground were telling me that the climate scientists were probably right. The other problem: more TV meteorologists are given 2-4 minutes to report the weather. It’s really tough, in that kind of format, to explain climate science and tie it into the regular weather segment. Don Shelby (who was initially skeptical about climate change too) and I tried to reference it from time to time, but again, there was amazing push-back. To their credit, management never said “don’t talk about climate change on the air”. They never tried to self-censor.
But on some level, we just knew that by even bringing it up we’d be accused of “buying into the liberal hype” of AGW. It’s really quite amazing. On some level I get it. It’s easier to deny than accept the truth, that actions have consequences. Our consumption-based lifestyle and addiction to fossil fuels has warmed the atmosphere, and that has implications. We can still mitigate some of the worst effects in the decades to come, but there’s now no doubt in my mind that, as a nation, we’re going to have to adapt to this brave new world.
“The main question I have is this: Why are so many weather forecasters in our public media so reluctant to endorse the reality of global warming (climate change)?
A related question: What percentage of forecasters do you estimate support the concept of global warming, and actively inform the public, as you do regularly?
My wife and I very much appreciate your taking a strong position on this topic and continuing to hammer home the reality of global warming, backed up splendidly with scientific data and illustrations. We subscribe to the daily email delivery of Climate Progress, which continues to inform readers of global warming’s dire consequences, especially in connection with growing human population, which leads to increased consumption of natural resources.
As avid environmental activists, we are using our musical skills to promote environmental and socio-political concerns, primarily via Eco Songs: Promoting Sustainability Through the Arts. We are also active in spearheading sustainability issues through the Green Committee of our condo association and a newly formed Citizens for Community Resilience and Sustainability group in St. Anthony. A group of five founding members created Insight Forum: Understanding and Preparing for a Future of Converging Crises (a 5-part video on YouTube), which we use as an introductory educational tool.
Please continue your greatly needed leadership in calling attention to this crucial issue. We only hope the mainstream media will get more involved in connecting the dots between global warming, the worldwide economic slowdown, widespread social unrest, and ongoing depletion of natural resources, including energy fossil fuels, arable lands, and wildlife.
Thank you, thank you for all you do!“
Clif and Bettye Ware
Professor Emeritus (voice). University of Minnesota, Twin Cities
Thanks Clif and Bettye – very much appreciate the note and words of encouragement. I tried to answer the question as best I can (above). My goal is not to throw any of the local meteorologists in town under the bus. We are blessed to have (real) meteorologists on the air in this market. Belinda, Dave, Chris and Ian are all exceptionally bright and well-informed, but you’ll probably have to ask them that question directly. I can’t and won’t speak for them.
I sense a slow turning of the tide. As I mentioned in a recent column, the weather is accomplishing what climate scientists couldn’t: convincing many Americans (those who still respond to logic, reason and data) that something is up – it’s not your grandfather’s weather pattern anymore. One blazing heat wave doesn’t prove anything. But our recent heat is only one puzzle piece. It’s an entire orchestra of weather oddities (playing out of tune, and loudly!) The pieces of the puzzle are coming together and most people can see the outline of what is emerging, and it’s troubling. It’s an accumulation of coincidences, and what’s unfolding is precisely what climate scientists predicted more than 30 years ago.
I asked Brad Johnson, from “Forecast The Facts“, a relatively new organization pushing the envelope, encouraging all TV meteorologists to report the science, not ideology or political talking points. Here was his response to your question:
“The best information we have about that is from Ed Maibach’s 2010 George Mason University poll:
More than half of our respondents (54%) indicated that global warming is happening, 25% indicated it isn’t, and 21% say they don’t know yet. About one-third (31%) reported that global warming is caused mostly by human activities, while almost two-thirds (63%) reported it is caused mostly by natural changes in the environment. In addition, Forecast the Facts has compiled a database of 72 local TV meteorologists who publicly question the science of climate change. We don’t have a public listing but we do display their comments:

Apple Set To Release “iPad Mini” To Battle Nexus 7? More rumors, speculation and details on a pint-size iPad coming soon? Details from gizmag.com; here’s an excerpt: “The trickling of rumors suggesting an iPad Mini is in the works has grown to become a raging torrent, with mainstream sources now seriously reporting on Apple’s plans for a smaller iPad. Previously, websites such as Digitimes have been the source of such rumors, but with The Wall Street Journal and Bloomberg now on board there seems less and less room for doubt such a device is on its way. Steve Jobs famously expressed his disinterest in the 7-inch tablet form factor on several occasions, eventually publicly ruling out suggestions that Apple was working on one. But with Tim Cook installed as CEO after Jobs’ death in 2011 things have changed, no doubt inspired by how the tablet market is growing and evolving over time.”
A Sweaty Weatherguy
The heat wave got personal yesterday. Our 25 year old air conditioner died in a screaming blaze of glory. Last week the A/C units in our studios failed, along with 2 emergency generators. What are the odds of that?
Recent heat was historic, but not unprecedented – ranked right up there with 1988 and 1934. Dust Bowl hot. What struck me was not only the scale and intensity of the heat, but that it came so early in the summer season. Dew points are higher now; 70 F. the new summer norm, making for much higher heat indices than during the mega-drought and heat wave of 1988.
Enjoy the fresh Canadian air while you can; no puddles (or wailing sirens) through Friday. A few T-storms are possible by Friday, spilling over into Saturday, but no widespread monsoon rains in sight.
The European (ECMWF) model has been doing a good job tipping me off about upcoming heat spikes some 4-8 days in advance. We may see 90-95 F by the weekend, and the model is hinting at highs in the low to mid 90s again early next week. Not record territory, but hot enough.
30 days above 90 F. this summer? Starting to think so – we’re already up to 17 days. Average is 13, if anyone asks. Doubtful.
A mostly-sweaty long range outlook. I’m going old school until further notice. A sturdy fan and a window. I’ll be the sweaty weatherguy, pointing toward Canada, hoping for a little relief…
Torrents And Droughts And Twisters – Oh My! Here’s a good overview of how a warmer, more energized atmosphere may impact specific weather factors, based on the latest IPCC predictions – courtesy of NCAR/UCAR AtmosNews: “Not all kinds of extreme weather have the same relationship with our atmosphere’s increasing burden of greenhouse gas. Below is a summary of what scientists already know and what they’re working to nail down, including some conclusions from recent reports by the Intergovernmental Panel on Climate Change (see What is the IPCC?). Click on each label or image to learn more about that phenomenon’s links to climate change. For help with the terminology used in IPCC statements, see the quick guide at bottom.”
Local View: Climate Change Affecting Food Production. Here’s an excerpt from Lincoln’s JournalStar.com: “…The bad news now, and into the far future, is that climate change is severely affecting food production across the planet, along with both population increases and rising affluence and diet changes of a growing middle class in emerging economies. Paradoxically, droughts and floods are two of the most damaging aspects of climate change.
Here are some facts:
• The 2011, Texas drought cost a record $8 billion in crop and livestock losses and up to 500 million forest trees died. Urban forests lost another 5.6 million trees, along with $280 million in economic and environmental values.
• Extremely hot summers that once covered less than 1 percent of Earth’s surface (from 1951-1980), “now covers about 10 percent of the land area,” according to one analysis. “We conclude that extreme heat waves, such as that in Texas and Oklahoma in 2011 and Moscow in 2010, were caused by global warming.”
• The Earth Policy Institute of Washington, D.C., warns that long-term food trends are worrisome, especially for soybeans. In 1955, “China produced the same amount of soybeans it consumed, but since then production has stayed the same and consumption has jumped fivefold.”
Climate Change: Global Warming Is A Fact. Here’s an excerpt from an Op-Ed at The Washington Post: “At some point we should stop litigating the basic question of whether climate change is happening. Climate change is a fact. The spike in atmospheric CO2 is a fact. The dramatic high-latitude warming is a fact. That the trends aren’t uniform and linear, and that there are anomalies here and there, does not change the long-term pattern. The warming trend has flattened out in the last decade but probably only because of air pollution from Chinese coal-fired power plants or somesuch forcing we haven’t fully discovered (smog is hardly the long-term solution we should be seeking). The broader patterns are clear. Models show the greatest warming spike down the road still, decades hence. Thus in a sense, saying that “this is what global warming is like” whenever we have a heat wave actually understates the problem.”
Climate Change Plays A Role In Wildfires – But Not The Only One. A warmer, drier climate is a big contributing factor in the record blazes out west, but not the only one. Here’s an excerpt in Time Magazine: “…But as important as global warming is to the raging fires in charred states like Colorado, it’s not the only factor—and no scientist would go so far as to say that climate change had caused one fire or another. While we’re changing the climate—loading the dice, in the climate scientist Michael Mann’s term, to make extreme weather more likely—we’re also changing the situation on the ground, moving ever larger numbers of people into fire-prone zones. It’s as if we’re adding fuel to the fire on both ends—which means we’ll be doubly burned. The great I-News Network has done an excellent job on the wildfires in Colorado, focusing not just on the immediate weather causes and the severe devastation of the fires themselves, but on the policies that have led so many Coloradans to build houses in what’s known as the “red zone”—territory on the edge of the wilderness that is prone to fire. (Hat tip to Andrew Revkin of Dot Earth for pointing out the I-News coverage.)”

U.S. Official: Higher Ocean Acidity Is Climate Change’s “Evil Twin”; Major Threat To Coral Reefs. The story from AP and The Washington Post; here’s an excerpt: “Ocean acidification has emerged as one of the biggest threats to coral reefs across the world, acting as the “osteoporosis of the sea” and threatening everything from food security to tourism to livelihoods, the head of a U.S. scientific agency said Monday. The speed by which the oceans’ acid levels has risen caught scientists off-guard, with the problem now considered to be climate change’s “equally evil twin,” National Oceanic and Atmospheric Administration chief Jane Lubchenco told The Associated Press.”
To Politicians Napping On The Fireline: Wake Up, Smell The Smoke And Act On Climate Change. Here’s a snippet from a Huffington Post story: “In 1987, I parachuted in with other smokejumpers to fight an Oregon wildfire that had a lot of folks particularly worried — and for good reason. It became known as the Silver Fire, the largest in a complex of wildfires ignited by some 1,600 lightning strikes in the parched forests between Northern California and Southern Oregon, requiring what at the time was the largest mobilization of firefighters in U.S. history. The Silver Fire eventually burned about 96,000 acres — roughly 150 square miles. The following year, Yellowstone burned up. Instead of firefighting that year, I was a Congressional policy analyst working on climate change issues. Given what I’d experienced the year before and what was happening in Yellowstone, I was worried about the future effects of climate change on wildfires.”

Welcome to the WeatherNation blog. Every day I sift through hundreds of stories, maps, graphics and meteorological web sites, trying to capture some of the most interesting weather nuggets, the stories behind the forecast. I’ll link to stories and share some of the web sites I use. I’m still passionate about the weather, have been ever since Tropical Storm Agnes flooded my home in Lancaster, PA in 1972. I’ve started 5 weather-related companies. “EarthWatch” created the world’s first 3-D weather graphics for TV stations – Steven Spielberg used our software in “Jurassic Park” and “Twister”. My last company, “Digital Cyclone”, personalized weather for cell phones. “My-Cast” was launched in 2001 and is still going strong on iPhone, Android and Blackberry. I sold DCI to Garmin in 2007 so I could focus on my latest venture: WeatherNation. I also write a daily weather column for The Star Tribune startribune.com/weather And if you’re on Twitter, you’ll find me @pdouglasweather
