Climate change got several nods during President Obama’s final State of the Union address on Tuesday. The president — looking positively radiant as he gazed upon congress members who will soon be someone else’s problem — named it as one of the major challenges facing both the country and his successor. He also called out climate deniers, perhaps referring to the ones vying for his job.

“Look, if anybody still wants to dispute the science around climate change, have at it,” the president said to scattered laughter. “You’ll be pretty lonely, because you’ll be debating our military, most of America’s business leaders, the majority of the American people, almost the entire scientific community, and 200 nations around the world who agree it’s a problem and intend to solve it,” he said, regarding the Paris climate agreement.

“But even if the planet wasn’t at stake,” Obama continued, “even if 2014 wasn’t the warmest year on record — until 2015 turned out even hotter — why would we want to pass up the chance for American businesses to produce and sell the energy of the future?”
