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.
But he said America "must lead" the transition to sustainable energy and "cannot cede to other nations the technology that will power new jobs and new industries."
