For those who haven't been following along at home, let me give some background. The UN IPCC (United Nations Intergovernmental Panel on Climate Change) is the body who produces Assessment Reports on the state of the climate every five years. This collects what is considered the best consensus science. The last Assessment Report is Assessment Report 5, or AR5. The section that Curry quoted is Working Group 2 (WGII) which (being to lazy to look up) is the report for government policymakers, providing guidance to those considering new laws.
So Curry quoted the consensus science intended to inform policy makers to Congress, and that guidance says "no disaster any time this century". I will bring this up next time I'm in a discussion with the Usual Suspects™.
The only people who object are, of course, Climate Change Deniers. Heh.
