Via Kim du Toit, Orson Scott Card gives us all the information you need to destroy the Global Warming Myth. But here's the problem -
The biggest proponents of Man-made Global Warming either already know it's bullshit, or have turned it into their religion. To the first group, any proof you offer doesn't matter because they already know it's crap. They're just using the myth to gain power, either political or economic. The second group refuses to listen to any proof, because that would destroy their worldview and thus cannot be accepted. Their actions are driven very little by science, and almost completely on their belief that Man-made Global Warming is real.
That's why we need to get the truth out to the next generation - to proof them against the indoctrination that the eco-freaks are trying to push.
