President Obama warned about climate change in his Berlin speech today:
"For the grim alternative affects all nations," said Obama of climate change. "More severe storms. More famine and floods. New waves of refugees. Coastlines that vanish. Oceans that rise. This is the future we must avert. This is the global threat of our time. And for the sake of future generations, our generation must move toward a global compact to confront a changing climate before it is too late. That is our job. That is our task. We have to get to work."
