NPR: Most scientist say "Warming Planet Can Mean More Snow"

"excerpt"]"The fact that the oceans are warmer now than they were, say, 30 years ago means there's about on average 4 percent more water vapor lurking around over the oceans than there was, say, in the 1970s," he (an expert the National Center for Atmospheric Research in Colorado) says.

Warmer water means more water vapor rises up into the air, and what goes up must come down.

"So one of the consequences of a warming ocean near a coastline like the East Coast and Washington, D.C., for instance, is that you can get dumped on with more snow partly as a consequence of global warming," he says.

And Trenberth notes that you don't need very cold temperatures to get big snow. In fact, when the mercury drops too low, it may be too cold to snow.

tweak something, and it changes

Decreased Water Vapor in Atmosphere Slowed Last Decade's Warming

Here's an interesting addition to global warming science: The National Oceanic and Atmospheric Administration says that decreases in water vapor ten miles above the Earth have slowed by one quarter the amount of surface warming that has occurred in the past ten years--which NASA recently confirmed was the hottest decade on record--while more water vapor in the 1990s increased warming:

However these variations in water vapor don't change "the fundamental conclusion that that world has warmed and that most of that warming has to do with greenhouse gas emissions caused by man," says report lead author Susan Solomon. (New York Times)

10% Decrease in Water Vapor = 25% Less Warming
The report, published today in the online edition of the journal Science, shows that stratospheric water concentrations decreased by 10% after the year 2000, leading to a 25% lower rate of global surface temperature increase from 2000-2009 than which would have occurred only due to carbon dioxide and other greenhouse gases.

These changes occurred precisely in a narrow part of the stratosphere where they would have the biggest impact on climate. The reason for the decline in water vapor is unknown.

30% More Warming in 1990s
Conversely, and relying on what the authors describe as "more limited data" from 1980-2000, increases in stratospheric water vapor during the 1990s actually led to a 30% increase in observed warming.

NOAA says this is the first report to link specific variations in observed warming to changes in stratospheric water vapor.

4. Time to invest in companies that make snowplows.

Because they sure are getting a workout this winter.

5. We're having yet another snowstorm here in southwest Tennnessee

in late February. That's just eerie. We should already be climbing up into the 50s for our highs. Our climate is truly fucked up. No doubt about it.

6. My daughter just posted this on her facebook....I took the same snippets

you did and posted it below her link as a comment....by brother is a dork-brained, no-such-thing-as global warming/climate change idiot....my daughter and I do this several times a month to show him the truth...he watches faux news....he's such an ass when it comes to politics and anything that has political overtones.
