Jonathan Overpeck Warming Quotations

We're saying that this could come much faster. The ice sheets are more vulnerable to climate warming than we had thought. The only good news I see is that we know about it in advance and can do something about it if we want.

We know when the sea level was that high in the past, and we know how much warming is necessary to get that amount of sea level rise from both Greenland and Antarctica.

The results suggest the threshold is close to the end of this century, and it could come sooner. The Arctic is already warming much faster than we thought it would. To think we're not going to get 4 to 5 degrees warmer in another 50 years is wishful thinking.
