"When Groundhog Day arrives Saturday, don't waste much time expecting to see your local groundhog. It's too early. Normal emergence in the Washington area is late February or early March — but a steadily warming world might change that."

"Microbes are known to be able to thrive in extreme environments, from inside fiery volcanoes to down on the bottom of the ocean. Now scientists have found a surprising number of them living in storm clouds tens of thousands of feet above the Earth. And those airborne microbes could play a role in global climate."

"Last fall, when Democrats and Republicans seemed unable to agree on anything, one bill glided through Congress with broad bipartisan support and won a quick signature from President Obama: the European Union Emissions Trading Scheme Prohibition Act of 2011."

"Lord Stern, author of the government-commissioned review on climate change that became the reference work for politicians and green campaigners, now says he underestimated the risks, and should have been more 'blunt' about the threat posed to the economy by rising temperatures."

It's not just that the billionaire Koch brothers have spent tens of millions to undermine science and stifle debate on climate change. It's that they do it in secret.

"WASHINGTON -- Climate change is getting renewed attention in Congress. Representative Henry Waxman of California and Senator Sheldon Whitehouse of Rhode Island, both Democrats, today announced the formation of a Task Force on Climate Change that will be active in both the House and the Senate."

Resilience means survival as a growing number of budget-strapped states states face environmental disasters -- often climate-related -- with inadequate help from the federal government.

"The Obama administration is likely to rely mostly on existing rules and on flexing executive power to execute its second-term environmental agenda, sidestepping Congress as it sets about radically reducing greenhouse gases generated by major polluters."

"Promoting a recent poll, CNN is treating climate change as a matter of opinion, saying Americans are divided over whether or not it is real. But the network itself has fueled such confusion, often failing to report that manmade emissions are driving climate change or giving credence to those who deny the science behind it."

"How hot is the controversial Keystone Pipeline controversy getting? The Sierra Club is — for the first time in its history — going to engage in civil disobedience on Feb. 17 in Washington, D.C., which is also a day that greenies predict will be 'the largest climate rally in history.'"

"Glaciers in the tropical Andes have shrunk by 30-50% since the 1970s, according to a study."

President Obama's vow to address climate change in his second Inaugural Address January 21 could actually prove more than bold words. Despite the failure of the 111th and 112th Congresses to pass a cap-and-trade bill or any other major climate change legislation, Obama clearly has the power to limit greenhouse gas emissions himself, using his Supreme Court-tested executive authority under the Clean Air Act and other powers. Key Congressional Democrats are urging him on.

"President Obama made addressing climate change the most prominent policy vow of his second Inaugural Address on Monday, setting in motion what Democrats say will be a deliberately paced but aggressive campaign built around the use of his executive powers to sidestep Congressional opposition."

"A Harvard academic has put the blame squarely for America's failure to act on climate change on environmental groups. She also argues that there is little prospect Barack Obama will put climate change on the top of his agenda in his second term."

"On Jan. 11, the National Climate Assessment Advisory Committee -- a consortium of 13 federal agencies -- released its third draft report on the impact of climate change on the U.S. As seems to be the rule with federal documents, it’s monstrously long, but fairly readable and the online table of contents is easy to navigate."
