Will we make it?

"We are virtually certain that climate change is occurring, and occurring because of man’s activities. We’re virtually certain the probability distribution curve is all bad. There’s no good things that’s going to come of this. But what’s uncertain is exactly which one of those things are going to occur and in what time frame. In the probability distribution curve is about a 50 percent probability that about half of all species will become extinct or be subject to extinction over this period of time. What we will never know on an ex ante basis is whether or not man be one of those casualties or not." J. Wayne Leonard, the Chairman and CEO of Entergy Corporation, the utility giant based in New Orleans
