Former Vice President Al Gore called for unity and urgency in the American response to climate change, saying he was encouraged by growing climate activism around the world, but alarmed by what he said is the imminence of irreversible, continuing environmental damage. “There’s both bad news and good news,” he said in an interview with ABC News Chief White House Correspondent Jonathan Karl. “The problem’s getting worse faster than we are mobilizing to solve it. However … we now have an upsurge in climate activism.” Gore acknowledged that climate change is “a global crisis that requires a global response,” and that to be successful, climate policies require international cooperation.
