"Climate scientists have long warned that global warming could unlock vast stores of the greenhouse gas methane that are frozen into the Arctic permafrost, setting off potentially significant increases in global warming. Now researchers at the University of Alaska, Fairbanks, and elsewhere say this change is under way in a little-studied area under the sea, the East Siberian Arctic Shelf, west of the Bering Strait."

"A new report shows predictions for a warming climate could be devastating to duck production in the Prairie Pothole Region."

"An independent board of scientists will be appointed to review the workings of the world’s top climate science panel, which has faced recriminations over inaccuracies in a 2007 report, a United Nations environmental spokesman said Friday."

"An iceberg the size of Luxembourg knocked loose from the Antarctic continent earlier this month could disrupt the ocean currents driving weather patterns around the globe, researchers said Thursday."

"Senate Majority Harry Reid (D-Nev.) has instructed Sen. John Kerry (D-Mass.) to produce a revamped climate bill as soon as possible, according to sources, a task Kerry intends to accomplish within two weeks."

While many scientists think global warming will bring more intense hurricanes, a new scientific paper suggests that the climate system may also work the other way around. Authors looking at data from the Pliocene era say hurricanes may have created a permanent El Nino condition that enhanced warming.

"The United Nations will have an extra round of climate change talks this April in Germany to speed up stalled climate negotiations."

"Emission cuts pledges made by 60 countries will not be enough to keep the average global temperature rise at 2 degrees Celsius or less, modeling released on Tuesday by the United Nations says."
