President Barack Obama gave the commencement speech at the University of California, Irvine today, and he focused heavily on the dangers of climate change.
"I'm telling you all this because I want to light a fire under you," he said. "The climate change deniers suggest there's still a debate over the science. There's not. The talking heads on cable news suggest public opinion is hopelessly deadlocked. It's not."
He also called the nearly 8,000 undergraduate and graduate students to action, as the address came just two weeks after Obama announced a new plan to cut power plant pollution.
"There's going to be a stubborn status quo and people determined to stymie your efforts to bring about change," he said. "There are going to be people who say you can't do something. There are going to be people who say you shouldn't bother trying. I've got some experience with this myself."
