"U.N. climate talks starting in Mexico this month will seek a complex set of interlocking deals to slow global warming but will fall well short of a new treaty, the U.N.'s climate chief said on Wednesday."

A new joint study by the World Bank and the U.N. says that the cost of preventing disasters related to climate change would be far less than post-disaster cleanup.

"The Environmental Protection Agency Wednesday unveiled what new large industrial plants will have to do to minimize their greenhouse gas emissions starting in January."

"Texas officials said Wednesday that they would refuse to implement a program that regulates the largest industrial sources of greenhouse gas emissions, despite new federal rules that give wide leeway to states to implement the program."

"Environmentalists seeking more information about a top state regulator's abrupt departure reacted skeptically Tuesday to Gov. Mark Parkinson's promise that Kansas is conducting a fair and thorough review of plans for a new coal-fired power plant. Environmental groups worry that Parkinson pushed Rod Bremby out as secretary of health and environment to ensure that the coal plant obtains a permit by year's end. The timing would allow the plant to avoid new federal rules taking effect Jan. 2 for greenhouse gas emissions linked to global warming."

"U.S. EPA announced the release today of final rules that will require oil and gas facilities and certain electronics manufacturing plants to begin keeping tabs on their greenhouse gas emissions next year."

"Abolishing fossil fuel subsidies would boost the world's economy, environment and energy security, the International Energy Agency said on Tuesday, referring to a pledge made by G20 countries."

"Scientists are bracing for a new wave of attacks and investigations by the incoming House majority."

"Cap-and-trade legislation is 'dead for the foreseeable future,' Sen. Lindsey Graham (R-S.C.) said this weekend as military leaders cited climate change as one of the world's top security challenges."

"In the face of  probes by a state attorney general, hints of  hostile congressional hearings and assaults from  critics in the blogosphere, hundreds of members of the American Geophysical Union are forming a rapid-response team aiming to challenge disinformation and misinformation deployed in the policy wars over global warming."
