Research Fellow David Legates, co-author of Hot Talk, Cold Science appears on KFTK radio in St. Louis. Legates talks about the biggest myths of climate science regarding the destruction of the planet. He says the climate is one of the most complicated systems and everything effects it. It cannot be simplified, he says, and if it is oversimplified, some come up with theories about controlling carbon dioxide. Changes in land use can change the warming of the earth, Legates says.
