Global warming dials up our risks: UN report

If the world doesn't cut pollution of heat-trapping gases, the already noticeable harms of global warming could spiral "out of control," the head of a United Nations scientific panel warned Monday. And he's not alone. The Obama White House says it is taking this new report as a call for action, with Secretary of State John Kerry saying "the costs of inaction are catastrophic." Rajendra Pachauri, chairman of the Intergovernmental Panel on Climate Change that issued the 32-volume, 2,610-page report Yokohama early Monday, told The Associated Press: "It is a call for action." Without reductions in emissions, he said, impacts from warming "could get out of control."
