In his December 11 post on Grist, Ross Gelbspan argues that we’ve already passed the point of no return with global warming, and climate activists are full of "hollow optimism".
There’s no doubt we’re already seeing signs of global warming. In our Climate 411 blog, we post signs of it all the time (see here, here, here, and here, for example). But just because the boat has started to leak doesn’t mean it can’t still get much worse. Our most dangerous response to climate change is despair. Now, more than ever, we need to act.
