In his State of the Union speech, President Barack Obama warned that Americans must take steps now to cut “our emissions of the dangerous carbon pollution that threatens our planet.” To justify these efforts, he appealed to the “overwhelming judgment of science,” pointing chiefly to recent weather extremes in the United States as evidence for the urgency of action. Skeptics “can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence,” Obama announced, but the president clearly does not. “Heat waves, droughts, wildfires, floods—all are now more frequent and more intense.” Is he right? This article takes a closer look at those trends the president cites. After that, it assesses what Obama wants to implement as a response.
