Global warming increases possibility of heat extremes

Thursday, March 29th, 2012

According to several top scientists, the March heat wave that has shattered records across a wide swath of the U.S. bears some of the hallmarks of global warming.

In email conversations, those same scientific researchers who specialize in studying the role climate change plays in influencing individual extreme events — a burgeoning field known as  “extreme event attribution” — said global warming may have made March’s soaring temperatures more likely to occur, although they add that natural variability has played a key role as well.

Alaska glaciers shed 46 billion tons of ice annually

Wednesday, February 15th, 2012

New estimates published this week in the online edition of the journal of Nature reports that Alaska glaciers have been shedding about 46 billion tons of ice each year, making America’s Arctic state the world’s single biggest contributor to glacier-fed sea level rise outside of Greenland or Antarctica. Still, Alaska remains a wee player in the global ice frappe, producing only about 8.5 percent of the world’s annual glacier shrinkage of 526 billion tons, according to the study, led by a team at the University of Colorado at Boulder.
