In June, President Obama's landmark speech at Georgetown University delivered a powerful message on the dangers the world faces from global warming – extreme weather, rising seas, increased wildfires, epic droughts. "We will be judged," he said, "as a people, as a society, and as a country, on where we go from here." So where do we go? In his first term, Obama enacted tougher vehicle mileage standards and doubled electricity from renewables. But he's still got a long way to go. Here are a few things the president could achieve in his second term.
Sign a treaty.
Climate change is a global problem – it needs a global solution. In 2009, Obama tried and failed to broker a global agreement to cut carbon pollution; in 2015, the nations of the world are meeting in Paris to try again to forge a legally binding agreement. Unlike the last time, the U.S. will really have to lead the way. A deal is likely; the question is, will it be tough enough to make a difference?
