President Obama said the debate over climate change is settled during his State of the Union speech on Tuesday evening.
"The shift to a cleaner energy economy won’t happen overnight, and it will require tough choices along the way," Obama said.
"And when our children’s children look us in the eye and ask if we did all we could to leave them a safer, more stable world, with new sources of energy, I want us to be able to say yes, we did," Obama added emphatically.
The comments were met with a standing ovation from the majority of Democrats. But Democratic Senator Joe Manchin (W.Va.), who represents a coal-producing state, didn't join in, and Rep. Michelle Bachmann (R-Minn.) was spotted shaking her head.
The president has made tackling climate change a priority of his second term. The centerpiece of the effort is new regulations from the Environmental Protection Agency that will limit carbon emissions from new and existing power plnats.
