Does climate change mean the end of civilization? Maybe that sounds crazy, but, then again, all the forecasts are deeply sobering. There are reasons for hope, sure, but there are also reasons to believe that humans are unleashing forces beyond anyone's control. If we assume for the sake of argument that we are on a collision course headed for global catastrophe, how do we make peace with that reality?
