Following my detour through California after attending the 9th International Conference on Climate Change in Las Vegas, I’m finally back home to find low temperatures in the 50s in Alabama (was Al Gore in town?).

Here are the two presentations I gave. The first presentation briefly summarized our published paper on the role of El Nino in causing about 1/2 of the global-average warming we have seen since the 1950s, and the resulting reduced equilibrium climate sensitivity estimate of 1.3 deg. C.

The second presentation was a very basic overview of what I think we know about “global warming” (almost nothing), and my vexatious consternation over the dearth of scientists who are willing to call for more atmospheric CO2, given all of the observed benefits to humanity and nature. Where is the scientific objectivity on this issue?

Here’s the (mildly entertaining) video of the 2nd talk:
