Get the heck outside and shovel the proof off your sidewalk. Laugh...laugh...laugh... TMT D.C. Snowstorm: How Global Warming Makes Blizzards Worse By BRYAN WALSH Bryan Walsh Wed Feb 10, 7:30 am ET As the blizzard-bound residents of the mid-Atlantic region get ready to dig themselves out of the third major storm of the season, they may stop to wonder two things: Why haven't we bothered to invest in a snow blower and, also, what happened to climate change? After all, it stands to reason that if the world is getting warmer - and the past decade was the hottest on record - major snowstorms should become a thing of the past, like Palm Pilots and majority rule in the Senate. Certainly that's what the Virginia state Republican Party thinks: the GOP aired an ad last weekend attacking two Democratic Congressmen for supporting the 2009 carbon-cap-and-trade bill, and using the recent storms to cast doubt on global warming. (See pictures of a massive blizzard hitting Washington, D.C.) Brace yourselves now - this may be a case of politicians twisting the facts. There is some evidence that climate change could in fact make such massive snowstorms more common, even as the world continues to warm. As the meteorologist Jeff Masters points out in his excellent blog at Weather Underground, the two major storms that hit Philadelphia, Baltimore and Washington, D.C., this winter - in December and during the first weekend of February - are already among the 10 heaviest snowfalls those cities have ever recorded. The chance of that happening in the same winter is incredibly unlikely. But there have been hints that it was coming. The 2009 U.S. Climate Impacts Report found that large-scale cold-weather storm systems have gradually tracked to the north in the U.S. over the past 50 years. While the frequency of storms in the middle latitudes has decreased as the climate has warmed, the intensity of those storms has increased. That's in part because of global warming - hotter air can hold more moisture, so when a storm gathers it can unleash massive amounts of snow. Colder air, by contrast, is drier; if we were in a truly vicious cold snap, like the one that occurred over much of the East Coast during parts of January, we would be unlikely to see heavy snowfall. (See pictures of the effects of global warming.) Climate models also suggest that while global warming may not make hurricanes more common, it could well intensify the storms that do occur and make them more destructive. But as far as winter storms go, shouldn't climate change make it too warm for snow to fall? Eventually that is likely to happen - but probably not for a while. In the meantime, warmer air could be supercharged with moisture and, as long as the temperature remains below 32°F, it will result in blizzards rather than drenching winter rainstorms. And while the mid-Atlantic has borne the brunt of the snowfall so far this winter, areas near lakes may get hit even worse. As global temperatures have risen, the winter ice cover over the Great Lakes has shrunk, which has led to even more moisture in the atmosphere and more snow in the already hard-hit Great Lakes region, according to a 2003 study in the Journal of Climate. (Read "Climate Accord Suggests a Global Will, if Not a Way.") Ultimately, however, it's a mistake to use any one storm - or even a season's worth of storms - to disprove climate change (or to prove it; some environmentalists have wrongly tied the lack of snow in Vancouver, the site of the Winter Olympic Games, which begin this month, to global warming). Weather is what will happen next weekend; climate is what will happen over the next decades and centuries. And while our ability to predict the former has become reasonably reliable, scientists are still a long way from being able to make accurate projections about the future of the global climate. Of course, that doesn't help you much when you're trying to locate your car under a foot of powder. |

Joe Gwinn LOL...another piece of evidence that global warming is doing a number on the climate. Snow in all 50 states? New storm could make that true. By Patrik Jonsson Patrik Jonsson 2 hrs 15 mins ago Atlanta – Three hundred plow trucks are lined up to combat an afternoon rush-hour snowstorm in Georgia, including traffic-congested Atlanta. In Mobile, Ala., kids are poised for a rare snowball fight. And fat flakes are already falling in Blountstown, Fla. This has been one of the most bizarre winters of the new century, with storm after storm slamming the East Coast in particular. And now, a storm that dropped a foot of snow Thursday on Dallas – Dallas! – could help bring about the presence of snow in all 50 states. That’s if the storm delivers a few inches, as expected, in parts of north Florida. If that indeed happens, meteorologists at AccuWeather and the National Oceanic and Atmospheric Administration (NOAA) say they expect some coverage in all 50 states. (In case you’re wondering, some of the tallest peaks in Hawaii have snow sprinkled on them.) “By the time the storm ends, we may be looking at a truly historic snow cover map to open up the weekend,” AccuWeather.com’s Joe Lundberg writes. This winter’s white legacy has inspired at least one meteorological project. "On Friday afternoon, I'm going to begin asking for photos of the snow," Patrick Marsh, a student employee at NOAA’s National Severe Storm Laboratory in Norman, Okla., told Oklahoma’s News 9 channel. "Hopefully I'll get photos from all 50 states, and if I do, I'll put them into a Google Earth map and make a snow snapshot of America." (Wanna help Mr. Marsh? Send pics to .) So what’s going on? Climate-change debate has been hot and heavy as official Washington shut down for four straight days. The wintry blasts, Time magazine explained, could actually be part of a global-warming trend. (We’ll let them explain that here.) Less controversial were the communal dig-outs taking place across Washington. Shovelers dubbed the comity “snowcialism.” More seriously, the storms are likely to nip American taxpayers as city and states burn through their snow-clearing budgets. “[S]end dough for snow,” Sen. Barbara Mikulski (D) of Maryland wrote in a plea to Homeland Security Secretary Janet Napolitano. The culprit, it appears, is a strong Pacific El Niño pattern that has stirred up a boatload of moisture rolling across Mexico, into the Gulf, and up through the South. All that is now colliding on a regular basis with unusually deep dips of Arctic air. At the same time, much of the Midwest is experiencing a comparatively mild snow season – even as Vancouver, British Columbia, is having to truck in snow for some of its Olympic events. Other notable events in this topsy-turvy season: The South saw one of the first big storms, frozen iguanas fell out of trees in Florida, and snowfall records were broken in a dozen cities including Baltimore, Philadelphia, and Washington. And winter is barely halfway over. (Punxsutawney Phil, after all, said we have at least six more weeks of winter to go.) “The snow blitz ... is truly a rare event that has no parallel in the historic record,” wrote Weather Underground’s Jeff Masters Friday morning. |
