“The Biggest Control Knob: Carbon Dioxide in Earth’s Climate History” (57:06)

Bjerknes Lecture at AGU2009. Presented by Richard B. Alley Earth and Environmental Systems Institute, Pennsylvania State University, University Park, Pennsylvania, USA

Great lecture by the master science communicator Prof. Alley.  The talk covers the very basics of paleoclimate: how do we know that CO2 is the main driver of climate.

The lecture is available for download at the AGU website, but unfortunately it is only available in flash format.

For your convenience I have made a vimeo-version available:
