"One of the stickiest points in international climate change negotiations is how to account for carbon dioxide and other greenhouse gas emissions produced to make goods that are then sold for export."

"The European Union's development chief may be forced to name and shame France, Germany and Italy for not living up to their aid commitments, contributing to a roughly $17 billion funding gap this year."

"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."

As Congress has gridlocked on climate change, the Obama EPA has pushed forward to regulate greenhouse emissions under its Clean Air Act authority. Now some Congress members are proposing legislation to prevent EPA from doing that as well. The key question is how much support they can win from coal- and oil-state Democrats.

The pace at which glaciers are melting in many places around the world from Asia to Alaska. An error in an estimate of Himalayan glacier melting in a 2007 UN report has been seized on by climate change deniers. But the evidence of widespread and rapid glacial melting is overwhelming.

"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."

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

"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."

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

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.

"U.S. EPA Administrator Lisa Jackson today defended the science underpinning pending climate regulations despite Senate Republicans' claims that global warming data has been thrown into doubt."

"Despite unanimous opposition from Republicans, Oregon's Senate passed a bill this afternoon aimed at cutting greenhouse gas emissions from cars, SUVs and pickup trucks in metropolitan areas even as the state's population grows."

"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."

"Facing mounting pressure from congressional lawmakers on both sides of the aisle, the Obama administration yesterday vowed to gradually phase in climate regulations for industrial sources."
