90+ Sunday (severe threat by evening). Better Memorial Day

63 F. high in the Twin Cities Saturday.

72 F. average high for May 26.
64 F. high temperature on May 26, 2011.
.64" rain fell Saturday.
8.82" rain so far in May in the metro area (MSP International).
2.82" normal rainfall for the first 26 days of May.


90+ F. high temperatures later today; dew points in the low 70s will make it feel tropical.
Severe storms possible by late afternoon or evening - stay alert for watches & warnings.

.94" additional rain predicted for tonight (NAM model).


Wet start Monday, but skies should become partly sunny midday and afternoon with a drying southwest wind at 10-20 and dew points falling through the 50s (far more comfortable than today).

Big Hail on Saturday. Here is one of the more significant hail reports from Saturday afternoon's storms: 1.75" diameter near Newport, in Washington county - close to golf ball size. More hail reports from NOAA here.


Sunday Severe Threat. A strong surge of hot, steamy air will spark waves of strong to severe thunderstorms today; an eastbound cool front may spark a few severe storms late Sunday into Sunday night across the Plains and Upper Midwest. Maps courtesy of SPC.


Flood Warning. Recent (torrential) rains have resulted in flooding in the Brainerd area and much of northern Minnesota. Closer to the metro area the South Fork Crow River below Mayer is flooding in Carver county; details from the local NWS office:

FOR THE LATEST INFORMATION CONCERNING THIS FLOOD EVENT.


Saturday Doppler Radar Rainfall Estimates. MPX Doppler showed some 1-3" estimated amounts south and southeast of the metro area yesterday, the heaviest (3") amounts from Hastings to Eau Claire - the same "supercell" that spawned golfball-size hail.


Monsoon Season. So much for the drought eh? Good grief. Like turning on a switch: instant inundation. Models all agree that more heavy rain will fall tonight, predicting anywhere from .8 to 1.8". I tend to agree with the NAM solution: around 1" of additional rain overnight.


Predicted Rainfall Tonight. An eastbound cool front will probably squeeze out the heaviest rainfall amounts from near Duluth and Hinckley to St. Cloud and the western suburbs of the Twin Cities, as much as 1-1.5" of additional rain.

"Specifically, numerous complaints were made to NOAA and the Department of Commerce Inspector General, which have now been verified, that the Chief Financial Officer of the National Weather Service (NWS) was misappropriating funds from his program accounts and redirecting them to 122 weather offices nationwide, which conduct critical forecasting of weather events and major storms." - part of a press release from Maine Senator Olympia Snowe's office; details below.

"For decades, solar activity has been trending downwards, even as temperatures have continued to rise. It's not that the researchers are being induced or compelled to some sort of biased interpretation of the data. Reality just happens to have a bias." - from an article about money and climate science at Ars Technica below.


"The total weight of CO2 that entered the atmosphere thanks to fossil-fuel burning last year was 31.6 billion metric tons (or nearly 35 billion old-fashioned tons). That’s a 3.2 percent increase over 2010, setting an all-time record. To see what that looks like in real time, you can check out Deutche Bank’s carbon counter, which pegs the accumulate weight at more than 3.7 trillion metric tons." - from a Climate Central story below.


"A September 2009 study by the Environmental Law Institute (ELI) provides a snapshot of this disparity. It found that between 2002 and 2008, the government gave fossil fuels $72.5 billion, corn ethanol $16.8 billion, and renewable energy $12.2 billion in subsidies. In other words, 71 percent of federal subsidies went to oil, natural gas and coal, while only 12 percent went to renewables."
"The question should be whether the government should continue to underwrite extremely profitable, mature industries--especially highly polluting ones--at the expense of nurturing new, promising low-carbon alternatives. The obvious answer is no. Renewables currently generate only about 5 percent of U.S. electricity, but by 2030 they have the potential to produce more than 40 percent, half coming from wind. That would just about replace the share currently generated by coal, which is responsible for more than 80 percent of U.S. utility sector carbon emissions."

Global Heat Wave Disasters. I had no idea there were 126 killer heat waves, worldwide, from 1980 - 2008, with 89,889 deaths linked to extreme heat. More details from preventionweb.net.
 

Cyclonic Swirl From "Beryl". Packing a 50-mph punch, Tropical Storm Beryl more closely resembled an extratropical storm Saturday  - conditions not ripe for hurricane development as it tracks toward Macon, Georgia or possibly Jacksonville over the next 72 hours. Beryl is limping along at about 5 mph toward the southwest. Image: grEarth.

Tropical Storm Beryl Discussion From Baron Services in Huntsville:

"Beryl remains classified as a sub-tropical Storm at 8pm by the National Hurricane Center.  The newest hurricane hunter report indicated maximum sustained winds at 50 mph with higher gusts.  Beryl is moving SW at 6 mph tonight and has intensified slightly with pressure at 998mb.
The ridge will keep building to the east and this will keep Beryl moving to the Southwest and turning to the West later on Sunday.  There is a small band of thunderstorms near the center of circulation, but little overall strengthening is expected for Beryl.  Dry air continues to be entrained, which is very apparent on water vapor imagery.  

Beryl is expected to make landfall somewhere along the northeast Florida coast Sunday evening.  The coast from northern Florida to South Carolina can expect storm surge of 1 to 3 ft during high tide.  Most models, including the BAMS, now have Beryl moving farther inland over the Florida panhandle than previously forecast.  From there models diverge somewhat as a middle level trough moves towards the Tennessee Valley and east coast.  This should pick Beryl (or the remains thereof) and pull it back east across southern Georgia/northern Florida and then up the east coast.  This is contingent on the strength of the approaching trough, however, and the higher resolution 15km BAMS has Beryl going as far west as Tallahassee before curving back to the NW."

Tropical Storm Beryl. Packing 45 mph sustained winds, Berly is expected to drift toward the southwest, coming ashore somewhere between Macon, Georga and Jacksonville, Florida sometime Tuesday. It is not expected to intensify into a hurricane. Map: NHC.



"Spaghetti Plot". Here are a couple dozen model solutions for the projected path of Beryl - almost all of them bring the storm ashore as a moderate tropical storm, somewhere between Macon and Jacksonville, before recurving to the northeast and swept out to sea. Map: source.


Tropical Storm "Bud" Brushes Mexico's West Coast. Here's an update from Huffington Post: "Bud is weakening and becoming increasingly disorganized in the Pacific just off Mexico. The U.S. National Hurricane Center in Miami said Saturday that Bud had degenerated to a remnant low. It was expected to dissipate within the next day or say. Maximum sustained winds had weakened significantly and were near 30 mph (48 kph) as the storm hovered about 15 miles (24 kilometers) off the coast of Cabo Corrientes, Mexico. Forecasters say the storm could still drop another inch or two of rain along Mexico's southwestern coast."


Michigan Wildfires From Space. The Columbia, South Carolina office of the NWS shared this, via Facebook: "Thought we would share with you an outstanding 250 meter resolution Visible satellite image from this afternoon in the Upper Peninsula of Michigan. Featured in the image is a large fire with a eastward drifting smoke plume. Also visible is the lake breeze boundary identified by the cumulus cloud field."

Sand Storm! Thanks to Wayne Angelo and Instagram, for capturing a massive sandstorm heading for the Phoenix area Friday.

Tornado Touchdown Confirmed Near Montreal. Yes, "Tornado Alley" is shifting north over time. Here's an excerpt of a story at Canada's CBC: "Environment Canada has confirmed an F-1 tornado touched down northwest of Montreal Friday night. Meterologist René Héroux from Environment Canada said the tornado touched down in St-Benoît-de-Mirabel. Damage at the scene suggests winds reached up to 150 km/h, he said. Trees were uprooted, roofs damaged and windows shattered as the severe storm rattled through southern Quebec Friday night. The Mirabel area, northwest of Montreal, was hit the hardest."

Bad Idea: Six Myths About How To React During A Disaster. I think Myth #6 is wrong - a ditch still offers more protection in a tornado than staying in your car, which will become airborne if it's a major tornado. But I learned a few new things from this story at foxbusiness.com; here's an excerpt: "Here are some common misconceptions about disaster preparedness and what you really need to do to stay safe.

Myth No. 2: Open the windows in your home to equalize the pressure caused by a tornado
 
This is a terrible idea for a couple of reasons, explains Julie Rochman, president of the Insurance Institute for Business & Home Safety. "A, it doesn't work. And B, it's a really bad idea to stand in front of a window when a tornado is flinging debris all over the place. Plus, if there's an opening in the window, you could be sucked out."
Rochman recommends that people "leave their windows alone and instead go to a windowless area, like a shelter, your basement or a windowless room."


 
"Safe Rooms" Too Expensive For Homeowners, Even In Tornado Country. Here's a story from the Star Tribune's Bill McAuliffe, picked up by scrippsnews.com: "Even in the heart of tornado country, where more than 3,000 tornado-damaged have been under repair the last year, there is still not a "safe room" in sight. Safe rooms are reinforced interior spaces designed to offer even more protection from tornadoes and hurricanes than basements do. But they're expensive. And across north Minneapolis, residents are even cutting corners on shingles, said contractor Ishmael Israel. "They're opting for the more economical route," Israel said, adding that typical disaster precautions in the neighborhood now include storing bottled water and having working flashlights and extra batteries. Safe rooms, which can also do double-duty as laundry rooms or bathrooms, are designed to withstand a blow from a 15-pound 2-by-4 fired at 100 mph. Flying debris, such as lumber, is one of the most dangerous features of a tornado. Standard safe rooms also offer overhead protection that basements often do not."

March 15 Storm Dumped Enough Water To Be Classified As A 1-In-100 Year Storm. Here's an update from The Peterborough Examiner, serving Ontario, California: "A storm that struck Peterborough on March 15, causing localized flooding in some neighbourhoods, dumped enough water on the city to be classified a one-in-100-year storm, shows a report that goes to city council Monday night. The city identified 83 road flooding locations, 23 culverts or catch basins that overflowed, 53 flooded basements and 45 sewage backup spots. Between 40 millimetres and 80 millimetres of rain fell on the city, depending on the location in the city, according the city’s rain gauge network. The city should only get hit by a storm that severe once every 100 years, utility services director Wayne Jackson states."

El Nino May Lessen Hurricane Risk. Right now we're in an ENSO-neutral situation (no El Nino or La Nina); ocean water temperatures in the Pacific pretty close to normal for late May. Some oceanographers are predicting a mild El Nino warming by the end of 2012, which correlates with stronger winds over the tropics, winds that can shred tropical depressions and prevent them from maturing into hurricanes. But El Nino may come too late for the 2012 hurricane season. Here's an excerpt from an msnbc.com story: "To say our weather in many parts of the country has not been normal of late. In fact, far from it when you consider the historic and severe hurricanes and tornadoes we have witnessed to the freak events like the halloween blizzard in the east to a lack of winter for millions of americans this past season. It's against that backdrop that today's official government hurricane forecast comes out just as America geared up for the traditional start of the summer kickoff weekend, and it's where we begin our reporting tonight with NBC's tom costello. Get ready for the ferocious power of mother nature . The official start of hurricane season is still a week away, but it's already been an active two weeks. tropical storm Alberto has come and gone as hurricane Bud churned off new mexico. now a category two storm. Today from NOAA, a prediction for a near normal hurricane season between june 1st and november 30th . That means 9 to 15 tropical storms with 4 to 8 strengthens into hurricanes. and one to three of those becoming major hurricanes , category 3 or greater. the big wild card , the warmer effect from EL Nino in the Pacific."

10 Steps To Take Before Storm Season. Forbes.com has some good advice for every family - this is geared more to residents of Hurricane Alley, but there are some good take-aways for the rest of us impacted by flooding and tornadoes. Here's an excerpt:
  1. "Locate and agree on a safe room.  Plan to find the lowest place in the house, without windows.  Usually this is the basement or an interior closet or storeroom.  Meet as a family and agree to the plan to meet there in case of emergency.  Be sure that each family member has a plan for shelter away from home in case of a storm that doesn’t allow everyone to get home.
  2. Supplies.  Be sure to keep supplies on hand in or near the safe room.  These should include:  water, a water purification kit, non-perishable snacks/food, blankets and pillows, clothing, first aid, medical equipment for special-needs family members, pre-moistened towelettes, hand sanitizer, zip-lock plastic bags, disposable eating ware, duct tape, necessary toiletries, flashlights with fresh batteries, radio, cell phone with charged batteries, entertainment items such as books, or games, pet care items.  If you have a baby or toddler you will need appropriate supplies:  diapers, baby food, formula, toys, etc.  You may want a battery-operated laptop with a cellular modem to be able to connect with email and Internet.
  3. Evacuation plan.  Have a plan if you will be required to evacuate due to incoming weather.  Hurricanes and floods approach more slowly giving people time to escape."

Snowe Calls For Action In Wake Of Reported Mismanagement Of National Weather Service Funding. From Maine Senator Olympia Snowe's D.C. offices - here's a snippet of a recent press release: "WASHINGTON, D.C. – In response to the announcement that the Director of the National Weather Service (NWS), Jack Hayes, was stepping down from his position today in response to an investigation that senior management at NWS misappropriated millions of taxpayer dollars, U.S. Senator Olympia J. Snowe (R-Maine), the Ranking Member of the Oceans, Atmosphere, Fisheries, and Coast Guard Subcommittee, released the following statement:  “The deeply troubling revelation that senior staff at the National Weather Service, which provides indispensible storm and weather forecasting, have been conducting improper and potentially illegal transfers of taxpayers’ money is unacceptable.  While the Director of the National Weather Service has stepped down, there are many more remaining questions which require answers from both National Oceanic and Atmospheric Administration and the Department of Commerce – and any and all individuals who bear responsibility in this misconduct must be held fully to account."

Record Heat For The Indy 500? The ECMWF model is predicting 34 C, which works out to 93.2 F. On the track temperatures may reach 115 F. Ouch. Here's an excerpt of a paper from Climate Nexus: "....a high-pressure system approaching the Ohio Valley could push temperatures for the 96th annual Indianapolis 500 into record-breaking territory. According to the National Weather Service office in Indianapolis, temperatures have reached 90 degrees only five times in race history, with 92 degrees in 1937 as the all-time high. If predicted temperatures are accurate, race weather may be the hottest on record and could create difficulties for both drivers and fans alike....Recording-breaking temperatures earlier in the year are consistent with the larger pattern of climate change, which makes heatwaves and other types of extreme weather both more frequent and more intense. For more information about how climate change is changing long-term weather trends, check out Climate Signals, a summary of the latest science around the connections between extreme weather and climate change."

TV Weather Reporter Caught Faking Storm During Live Broadcast (Video). Oops! I've been trying to do this with a tornado for years now, but no luck. Hey, it's all about the ratings, right? Think we can fake a stunningly beautiful Memorial Day Weekend? Check out the fake sandstorm video from Yahoo News; here's an excerpt: "A Romanian TV weatherman has put a new spin on the phrase "having sand kicked in your face," after he was caught faking a storm during a live news report. The Metro reports that the reporter was filing a story about heavy winds along the Black Sea coast, which were gusting at more than 60 mph. At least, the winds were blowing that hard before the weatherman began filing his report. But by the time he went live, the winds had apparently died down. So in an attempt to recreate the stormy conditions, the reporter had a production assistant begin kicking sand in his direction. The reporter then told viewers, "The wind blows with incredible power; there are moments when it is impossible to stand up here. The wind blows the sand at over 60 km per hour. It blew away the beach umbrellas and the tourists had to leave in a hurry."

How To Destroy The Internet. No, don't do this - not even sure Gizmodo.com should be doing a story on this (or I should be republishing it) - but I came away from this article believing that it's probably impossible to bring down the entire net. It would take a massive coordinated effort on nearly every continent, at least doing it the conventional way. What I worry about (a little) is someone finding an unconventional way to wreak havoc. Here's an excerpt: "Remember when Anonymous threatened to destroy the entire internet? We laughed, and ultimately their words were just hacker hubris. But it got us thinking—could someone actually destroy the Internet? We did some digging, and guess what: With enough effort, the entire thing can be shattered. Physically. Completely. Here's how to kill the net. Before we destroy mankind's greatest, vastest machine, let's get something polite out of the way: don't. Destroying the Internet's core infrastructure would constitute the greatest act of global terrorism in history and/or a declaration of war against every sovereign nation in existence—to say nothing of the danger it would put both you and others in. This is a thought exercise.


Some Warm Front. Saturday's high temperature prediction was a bust - the warm front got hung up over the metro, keeping highs stuck in the 60s, while readings soared into the 90s over Iowa. Rainfall ranted from .44" at St. Cloud to .64" Twin Cities to nearly 1" at Redwood Falls. This stubborn front finally lifts north today, and temperatures should hit or top 90.



Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:


TODAY: Periods of sun, uncomfortable humidity levels. Dew point: 72. Winds: S/SE 10-20+. High: 92

SUNDAY NIGHT: T-storms likely, some potentially severe. Another 1" of rain possible. Low: 66

MEMORIAL DAY: Soggy/stormy start, midday and PM clearing with lower humidity. Winds: SW/W 15-25. High: near 80

TUESDAY: Cooler, clouds increase by afternoon. Low: 54. High: 66

WEDNESDAY: Comfortable, mix of clouds & sun. Low: 48. High: 64

THURSDAY: Partly sunny, still dry. Low: 49. High: 70

FRIDAY: Blue sky, few complaints...still dry. Low: 51. High: 74

SATURDAY: Patchy clouds, not bad (for a weekend). Low: 56. High: 77



Sunday Sauna

I should be serving towels (and helmets) with this forecast. And for the record: that "dry bias" I was seeing on the maps a few weeks ago? Never mind.

We're closing in on 10" of rain for May; at this rate I may be growing rice, not roses, in my back yard.
Climate change making our weather patterns more erratic: perception or reality? 86" of snow 2010-2011, 22" last winter. Green lawns and boats on Minnesota lakes in late March, followed by a flip-flop from severe drought to perpetual flood in, what, 3 weeks? Weather on steroids.

Minnesota monsoon season gives way to a hot front today, temperatures nearly 40 degrees warmer than Thursday AM. If the sun stays out for a few hours today (likely) we should see low to mid 90s, with a drippy, debilitating dew point above 70. 

Guam - with lakes.

While you slather on sunscreen and splash in your favorite lake keep a watchful eye on the western sky. Conditions are ripe for another round of strong/severe T-storms by tonight.

Up to one inch of rain may falls tonight, but Monday morning puddles give way to rapid clearing, dew points falling through the 50s. We may actually salvage a decent Memorial Day; highs near 80. 

It's a meteorological miracle!

Climate Stories...

  Bonn Climate Talks End In Discord And Disappointment. The story from Climate Central and OPB News; here's an excerpt: "The latest round of international climate change talks finished on Friday in discord and disappointment, with some participants concerned that important progress made last year was being unpicked. At the talks, countries were supposed to set out a work plan on negotiations that should result in a new global climate treaty, to be drafted by the end of 2015 and to come into force in 2020. But participants told the Guardian they were downbeat, disappointed and frustrated that the decision to work on a new treaty – reached after marathon late-running talks last December in Durban – was being questioned."

It's Not About Climate Change, It's About Keeping Advertisers Happy. An interesting perspective - and not the first time I've encountered this train of thought: "Let's hold off reporting on what's happening with climate trends, because it might make some of our advertisers, the men and women who pay the bills, a little uncomfortable." Right. Here's an excerpt from a post at fair.org: "Scientific American has a dilemma (Extra!, 2/11): It takes advertising from oil companies whose profits depend on denying the most important scientific fact of our era, the reality of human-caused climate change. The magazine would lose its whole brand identity if it pretended global warming wasn't happening, but there are things short of that that will make its fossil-fuel-selling advertisers a little happier. Such as running blog posts like "It's Not About Tar Sands–It's About Us" by Melissa C. Lott and Scott McNally (5/23/12). Lott and McNally–both of whom have worked for the energy industry when they aren't science blogging–dispute the idea that people concerned with climate change ought to discourage Canada from extracting and burning its tar sands, because: Stopping Canada from producing tar sands will not curb the world's oil demand, reduce fossil fuel consumption or significantly reduce our total greenhouse gas footprint."


Knocking The Wind Out of U.S. Energy Options. Here's a snippet from an important, scientifically eloquent Huffington Post article: "Unless Congress acts soon, the wind industry will have to trim its sails--and its workforce. An essential federal tax break for the fledgling industry, scheduled to expire at the end of the year, has become a victim of Washington gridlock. President Obama was in Newton, Iowa, yesterday at TPI Composites, a leading wind blade manufacturer, to again ask Congress to extend the production tax credit, which provides a credit of 2.2 cents per kilowatt-hour of electricity produced by wind turbines--as well as geothermal, biomass and underwater turbines--for the first 10 years of production. The president also urged Congress to expand a 30 percent tax credit instituted in 2009 for investments in companies manufacturing renewable energy components. The package, called the Advanced Energy Manufacturing Tax Credit, provided $2.3 billion in credits for solar panel parts, "smart" electric meters, fuel cell components and wind turbines."

U.S. Cut Its Carbon Emissions In 2011 - But China Erased The Gains. The problem? Coal-fired energy, which China is leaning on heavily for its growth - it's the dirtiest fuel, from a carbon emissions standpoint; here's a clip from a Washington Post story: "Yes, it’s true: Americans are slowly starting to tackle global warming. U.S. carbon emissions dropped 1.7 percent last year, according to the International Energy Agency. But that only went so far. Thanks to China’s fast growth, the world’s greenhouse-gas emissions hit record highs in 2011. How did the United States managed to restrain its carbon-dioxide? The IEA offers up three reasons for the decline: First, many U.S. power companies have been swapping out coal for somewhat cleaner natural gas, since the latter has become so cheap. That’s helped. The United States also had a mild winter in 2011, which meant less energy was needed for heating. Finally, Americans have been driving less and purchasing more efficient cars of late, which has tempered the country’s oil use. It wasn’t a huge drop. It may prove fleeting. But it was a step toward less carbon."

Greenhouse Gas Emissions Across The Globe Hit A Record High. Following up on the story above comes this piece from Climate Central: "Thanks to developing countries like China, greenhouse-gas emissions across the globe hit record highs in 2011, according to the International Energy Agency (IEA). While the IEA’s report is a preliminary estimate of carbon dioxide emissions for 2011, the news as a whole is not good. The total weight of CO2 that entered the atmosphere thanks to fossil-fuel burning last year was 31.6 billion metric tons (or nearly 35 billion old-fashioned tons). That’s a 3.2 percent increase over 2010, setting an all-time record. To see what that looks like in real time, you can check out Deutche Bank’s carbon counter, which pegs the accumulate weight at more than 3.7 trillion metric tons."


Climate Armageddon: How The World's Weather Could Quickly Run Amok (Excerpt). Here's a troubling excerpt of a story at Scientific American: "The eminent British scientist James Lovelock, back in the 1970s, formulated his theory of Gaia, which held that the Earth was a kind of super organism. It had a self-regulating quality that would keep everything within that narrow band that made life possible. If things got too warm or too cold—if sunlight varied, or volcanoes caused a fall in temperatures, and so forth—Gaia would eventually compensate. This was a comforting notion. It was also wrong, as Lovelock himself later concluded. "I have to tell you, as members of the Earth's family and an intimate part of it, that you and especially civilization are in grave danger," he wrote in the Independent in 2006. The world has warmed since those heady days of Gaia, and scientists have grown gloomier in their assessment of the state of the world's climate. NASA climate scientist James Hanson has warned of a "Venus effect," in which runaway warming turns Earth into an uninhabitable desert, with a surface temperature high enough to melt lead, sometime in the next few centuries."

Timescale Matters: 800,000 Years Of CO2 (NOAA). I was floored when I saw this YouTube clip from NOAA, tracking CO2 levels going back 800,000 years (tracking carbon is Antarctic ice core samples). The data set shows a spike between 20 and 70 North Latitude, and it's the rate of CO2 increase that is alarming. We've had increases in the past (related to changes in the Earth's orbit around the sun), but the atmosphere has never seen a CO2 spike like the one we've experienced in the last 50 years. More from NOAA: "Time history of atmospheric carbon dioxide from 800,000 years before present until January, 2009. Recommend full screen/HD to read titles. See http://carbontracker.noaa.gov for more information on the global carbon cycle."

The Big Picture. Data going back 800,000 years before Christ show fluctuations in CO2 levels, but during the warm (astronomical) cycles CO2 levels stayed within at 225-300 ppm range. We're now over 392 ppm, and unless we begin reducing greenhouse gas levels (soon) those levels may double by the end of the century, resulting in a 3-8 F. temperature rise worldwide. I'm sure how much clearer the trends need to be before reasonable, logical people realize that we have a bit of a problem here. YouTube animation courtesy of NOAA.

Killer Heat Waves: Heat-Related U.S. Deaths Could Increase By 150,000 By Century's End Due To Climate Change. Here's a clip from an NRDC article: "NRDC released a report today projecting that more than 150,000 additional Americans could die by the end of this century due to excessive heat caused by climate change. This startling conclusion is based on peer-reviewed scientific papers published recently by Dr. Larry Kalkstein and colleagues. This is the kind of study that should make headlines around the country but is generally ignored when published only in scholarly journals. So NRDC is presenting the information in a more accessible manner, adding calculations of the cumulative additional death toll attributable to projected global warming by mid-century and century’s end (the report, including these additional calculations, was reviewed by Dr. Kalkstein to ensure that we have presented the information accurately)."

Climate Change Allows Once-Rare British Butterfly To Thrive. The story from The Christian Science Monitor: "Warming in Great Britain appears to have given a little brown and orange butterfly an edge. The brown argus butterfly has spread about 49 miles (79 kilometers) northward on the island over 20 years, observations indicate. Although it's well known that climate change can prompt plants and animals to shift the ranges in which they live, the brown argus (Aricia agestis) has widened its living quarters with unusual speed, according to an analysis of decades of data collected by British volunteers. The butterfly's secret? A new host plant to feed its larvae."

Climate Change And The Media. Here's a post from redding.com: "According to Yahoo News, the Casey Anthony trial was the number one issue in 2011. Global climate change did not make the top ten, although, according to the National Oceanic and Atmospheric Administration, the U.S. experienced "14 weather and climate disasters in 2011, each (of which) caused $1 billion or more in damages -- and most regrettably, loss of human lives and property." When Rasmussen recently conducted a national telephone survey of what Americans considered the most important issues, global climate change was not mentioned. Number one on the list was the economy with 82 percent of Americans reporting this as being very important. Their tenth concern was Afghanistan with 27 percent of Americans citing the war as very important."

Countries Doing Too Little On Warming: Research. Reuters has the details: "Greenhouse gas emissions in 2020 could rise to nine billion metric tons (9.92 billion tons) above what is needed to limit global warming as some countries look set to miss their emissions cut targets, a report by three climate research groups said on Wednesday. Countries have agreed that deep emissions cuts are needed to limit an increase in global average temperature to less than 2 degrees Celsius this century above pre-industrial levels, a threshold that scientists say is the minimum required to limit devastating effects like crop failure and melting glaciers. They believe the 2 degree limit is only possible if emissions levels are kept to around 44 billion metric tons of carbon dioxide equivalent in 2020."

Accusations That Climate Science Is Money-Driven Reveal Ignorance Of How Science Is Done. Here's an excerpt of an eye-opening article from Ars Technica: "One of the unfortunate memes that has made repeated appearances in the climate debate is that money isn't just influencing the public debate about science, but it's also influencing the science itself. The government, the argument goes, is paying scientists specifically to demonstrate that carbon dioxide is the major culprit in recent climate change, and the money available to do so is exploding. Although the argument displays a profound misunderstanding of how science and science funding work, it's just not going away. Just this week, one of the sites where people congregate to criticize mainstream climate science once again repeated it, replete with the graph below. That graph originated in a 2009 report from a think tank called the Science & Public Policy Institute (notable for using the serially confused Christopher Monckton as a policy advisor). The report, called "Climate Money: The climate industry: $79 billion so far—trillions to come" (PDF) and prepared by Australian journalist Joanne Nova for the Science & Public Policy Institute, claims to show how money has distorted climate science."
