From the December 2012 issue of Scientific American:
"Loss of Arctic sea ice is stacking the deck in favor of harsh winter weather in the U.S. and Europe."
"Global warming has increased the loss of sea ice in the Actic, which has altered atmospheric conditions that influence winter weather in the U.S. and Europe.
"The changes lead to invasions of Arctic air into the middle latitudes, increasing the likelihood of severe winter outbreaks, which occurred in the easter U.S. and northern Europe in 2010 and 2011 and in eastern Europe in January 2012.
"The deck may be stacked for harsh outbreaks during the 2012-2013 winter in North America and Europe."
This article was researched, written and printed long before Megatorm Sandy trashed the northeastern seaboard. It points out that Arctic sea ice melting is accelerating rapidly--at the extreme end of the most pessimistic estimates of global warming by climate scientists.
Note that the article doesn't mention the debate about whether there's global warming, or whether human activities are seriously affecting it. That's because there's no debate to discuss within the world of science--any more than there's a debate about Newtonian mechanics, or evolution, or the age of the Earth.
The only debate is in the boardrooms of oil and coal producers as to how to fool Americans who understand nothing about science into thinking there's a debate within the scientific community, just as their friends in the tobacco industry did the same kind of thing and thus, with the aid of politicians in their pay, delayed the onset of regulation for several very profitable decades.
