Prof. Ian Plimer: There Is Zero Evidence CO₂ Drives Global Warming

Leading geologist Prof. Ian Plimer: There is "absolutely no evidence whatsoever" that CO₂ drives global warming.

"If we're looking at modern warming, we've got to be able to look at what's happened with past warmings, and how these past warmings have been natural."

"We see no evidence from the past that carbon dioxide drives warming. Absolutely no evidence whatsoever."

"The whole popular paradigm that this plant food... drives global warming, we see no evidence for that."
