"When President Obama during his inauguration speech made a case for tackling human-driven climate change, it felt like deja vu for many in the environmental community -- including members of religious groups who have long looked to him for action."

Climate change is already creating refugees along the coastal lowlands of Bangladesh.

"Heat rising up from cities such as New York, Paris and Tokyo might be remotely warming up winters far away in some rural parts of Alaska, Canada, and Siberia, a surprising study theorizes."

"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.

"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.
