Ivar Giaever: The Strange Case of “Global Warming”
Here's the prebuttal (the talk before this one). Near the end, Mario Molina is very direct about the next speaker -- he makes it clear that he thinks the arguments are nonsense and coming from a non-expert, the word "ashamed" is used, and so on:
Mario J. Molina: The Science and Policy of Climate Change
Photosynthesis, Biomass, Biofuels: Conversion Efficiencies and Consequences, by Hartmut Michel (he ends up recommending photovoltaic cells and batteries to power cars rather than biogas or biofuels which are much less efficient)
Atmospheric Chemistry and Climate in the Anthropocene, by Paul J. Crutzen
(the last talk is a bit dry).
It's interesting to see Nobel Prize winners in physics accusing each other of engaging in religion/politics rather than science, etc., etc. It all sounds quite familiar.
