It's not fair to say it's unanimous. It's a target, actually, that the European Union adopted as long ago as 1996, over 10 years ago, so this has been around for a long time. What really struck me in the last little while is that leading climate scientists who used to be very cautious about stating an opinion on what would be dangerous climate change--because that does involve not just scientific evidence but also a value judgment--are now coming forward in substantial numbers. I cited that Bali Climate Declaration by Scientists as a striking example of this.
A lot of the scientists are now getting so impatient that they're saying, “Look, you governments, two degrees Celsius would just be unacceptable, from our understanding of all the projections that are made of impacts.” Now many of them, as I said in my presentation, are saying this two degrees Celsius has to be the prime goal of the new global deal we hope will be under negotiation going out of Bali.
