The Biggest Control Knob: Carbon Dioxide in Earth’s Climate History

Here is an excellent keynote address by Dr. Richard B. Alley, Penn. State Univ., from December 2009 in which he shows that the important controller of Earth’s Climate is carbon dioxide, mainly through volcanic forcing and rock weathering, and on a small scale, plate-tectonic drifting and the evolution of plant life. He also points out the changes in the sun, cosmic rays, space dust, and magnetic fields have little bearing on climate.

He is an animated speaker and, though the subject is somewhat difficult, it is well-worth the time. You will find the address HERE.
