IRVINE, Calif., June 6 (UPI) -- U.S. scientists say dirty snow might be as much to blame as greenhouse gases for a third or more of Arctic warming. U niversity of California-Irvine Associate Professor Charlie Zender said snow becomes dirty as the result of soot from vehicle tailpipes, smoke stacks and forest fires that enters the atmosphere and falls to the ground.
Soot-infused snow is darker than natural snow and dark surfaces absorb sunlight and cause warming, Zender said. Bright surfaces reflect heat back into space and cause cooling.
"When we inject dirty particles into the atmosphere and they fall onto snow, the net effect is we warm the polar latitudes," said Zender. "Dark soot can heat up quickly. It's like placing tiny toaster ovens into the snow pack."
The study appears in the Journal of Geophysical Research.
Giggling...
...ping.
I love it when they talk all science-like.
And my guess as to which country puts the most soot in the air is China.
Cute.
Immensely stupid analogy, but cute in its own unique way.
What will they think of next?
Something, perhaps, SCIENTIFIC?
Amnesty International, Greenpeace, People for the American Way, Al Gore, and Micheal Moore all want you to know this is all U.S. dirty snow, not Chinese, Indian, or Mexican dirty snow.
With 500 more coal fired power plants coming online.
Remember the Newsweek piece on global cooling from 1975. It actually speculated that one of the ways they could reverse the cooling would be to put soot on the arctic caps. MOWGLI!!!
I’ve only known yellow snow to have any warmth.
Too bad their stretch exceeds their grasp.

ROTFLMAO! Guess they haven’t heard that there is a SUMMER in the Arctic, too.
Dirty snow? Well you have given me cause for a pause on this one and that’s my final answer!
And about 20% of their coalfields on fire....

Great googly-moogly. What a load of nonsense. Which thing puts more particulate matter into the air: cars, smokestacks or forest fires?
Which one has been radically lowered? All of them.
Forest fires used to burn for months and in centuries past would consume whole states.
Where’s the data on that?
How about a bunch of fairly new dirty coal-burning power plants in China? It would be interesting to track the increase in coal use in China to warming in the Arctic.
For some reason, I keep thinking about a song by Frank Zappa....
Watch out where the Huskies go
And don't you eat that yellow snow...
How conveeeeeeenient!
Now that warming on Mars has proven man-made global warming to be a complete hoax, they have to come up with something else. Dirty snow!!! Of course! Why didn't we think of that before??? Nanook...how could you!
"Watch out where the huskies go...don't you eat that yellow snow"
For goodness sake, all I did was write my name in it...
