Most of the paper is solid, telling us new things about the recent history of our planet. But there appears to be some significant issues with one aspect of the analysis: the part that attempts to calculate how sensitive our climate is to rising greenhouse gasses. Unfortunately, that’s the aspect that’s most relevant to non-scientists, and it’s the detail likely to attract the most attention.

Yes, it would be most unfortunate if the American public understood that scientists still don’t understand greenhouse gasses, upon which so much public policy is made.
