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.

“But the debate is settled. Climate change is a fact.”

“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.
