Smoking causes cancer. Anybody who thinks it doesn't is delusional.

About the sort of response I expected. Here we have overwhelming evidence of outright scientific fraud, and you wax sarcastic. Nobody with a modicum of scientific training denies that an increase in CO2 will tilt the energy balance in a positive direction, but the hard facts are that there are many other factors, both known and unknown, which govern whether the earth itself warms and cools. And right now, the hard facts are that the earth has ceased to warm, and the models didn't predict it.
