WASHINGTON - President Barack Obama is pledging to respond to what he calls "the threat of climate change."
He says that failing to do so would be a betrayal of the nation's children, and of future generations.
Obama spoke Monday in his second inaugural address. He said that while some might deny the "overwhelming judgment of science" -- a reference to those who say they don't believe in global warming -- no one can escape extreme weather like raging fires, drought and storms.
Obama tried and failed in his first term to get a climate change bill through Congress.
