The real question is how fast can adaptations be made. Majority of dinosaurs couldn't do it, leaving only birds since they could quickly move to more hospitable climates.

The claim right now is the climate is changing too fast for the ecosystem and adaptations to play catch-up, resulting in some serious problems for wildlife. Yes, the only outcome will be those that can adapt or move to where survival is possible. Personally I don't know what will happen, and I don't want to get into R&P land, I just don't like what I am experiencing. Warm air pumps all the way to the poles, displacing this cold crap, making me miserable.

It snowed again, hard, this afternoon and it wasn't supposed to.
