While acknowledging that "no single event makes a trend," the President noted that the United States had been buffeted by extreme weather events that in many cases encapsulated the predictions of climate scientists. "But the fact is, the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, and floods — all are now more frequent and intense. We 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. Or we can choose to believe in the overwhelming judgment of science — and act before it’s too late," Obama added."
