Although he was probably already preaching to the choir, President Obama used his commencement address at the University of California, Irvine to take swings against climate change deniers. Speaking to the crowd at Angel Stadium in Anaheim on Saturday, he called out those afraid to admit the science behind climate change is real. "There are some who duck the question by saying, 'Hey, I'm not a scientist.' Let me translate that for you: What that means is, 'I accept that man-made climate change is real, but if I admit it, I'll be run out of town by a radical fringe that thinks climate science is a liberal plot,'" he told the cheering crowd. Continuing his less than subtle attack against climate change doubters, he preached studying the sciences as a way to arm them against "a stubborn status quo, people determined to stymie your efforts to bring about change."
