Beto O'Rourke says 12 years remain til end of the world

"This is the final chance. The scientists are unanimous on this. We have no more than 12 years to take incredibly bold action on this crisis," he said at a campaign event last month in Keokuk, Iowa.

"They say we should do nothing less than marshal every resource in the country to meet that challenge, to reduce our dependence on fossil fuels, to get to net zero emissions, which means not only must we emit less greenhouse gasses, we must plant things that absorb greenhouse gasses and Carbon and invest in the technology to allow us to claim some that are in the air now. Can we make it? I don't know. It's up to every one of us. Do you want to make it?"
