"North American bird species are 'facing a new threat -- climate change -- that could dramatically alter their habitat and food supply and push many species towards extinction,' said Secretary of the Interior Ken Salazar on Thursday when he announced the new report, 'The State of the Birds: 2010 Report on Climate Change.'"

"U.S. EPA settled a lawsuit [last week] by agreeing to use the Clean Water Act to address ocean acidification, a move that some see as opening a side door to federal curbs on greenhouse gases that scientists link to problems in the marine environment."

"The White House is finalizing rules on the first U.S. greenhouse gas emission standard for automobiles, which would raise average fuel economy 42 percent by 2016 in a bid to slash oil imports and fight climate change."

"UNITED NATIONS -- At a tumultuous time in U.N.-led climate negotiations, one of the world's most credible scientific groups agreed Wednesday to plug the recent cracks in the authoritative reports of the United Nations' Nobel Prize-winning global warming panel."

"President Barack Obama made a renewed push for a long-stalled climate and energy bill Tuesday, urging lawmakers at a White House meeting to pass a comprehensive bill this year."

"China and India formally agreed Tuesday to join the international climate change agreement reached in December in Copenhagen, the last two major economies to sign up."

"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."

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.

"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.

"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."

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