Talking nice about sun and wind and green jobs is just greenwash.

How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree... We don't have much time left.

...the global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change.

The 5-year mean global temperature has been flat for the last decade, which we interpret as a combination of natural variability and a slow down in the growth rate of net climate forcing.

Injection of environmental and political perspectives in midstream of the science discussion cannot help the process of inquiry. I believe that persons with relevant scientific expertise should concentrate, with pride, on cool objective analysis, providing information to the public and decision-makers when it is found, but leaving the moral implications for later common consideration, or at most for summary inferential discussion.

The evidence for human-made climate change is overwhelming.

The United States did not sign Kyoto, yet its emissions are not that different from the countries that did sign it.
