The Biggest Control Knob - Carbon Dioxide In Earth's Climate History

If you haven't seen Dr Richard Alley's AGU lecture, I recommend it.

There is some good evidence presented that co2 is a big factor in climate across geological time, although the surrounding info about how co2 and temperature paleodata are gathered and how co2 and temperature have changed over geological time is interesting in itself.

And if you've ever wanted to see an audience of scientists laughing at a denialist's stupid accusations then this is the video for you.
