Just to be clear, I say AGW is the Greatest Scientific Hoax in human history. There's is not a single shred of genuine scientific evidence, not a single repeatable laboratory experiment ever performed that demonstrates how even an instantaneous 100PPM increase in CO2 raises temperature
That's part of the same argument creation "scientists" use against evolution. A lack of 100% proof is what bible thumpers and anti environmentalists use to cast doubt on the current and completely repeatable laboratory experiments that support man's affect on global warming, and evolution.
Did you know that the last time C02 levels were 20 times higher than they are now...the sea level was the highest it's ever been in earth's history? It's Al Gore's wet dream come true!. I'm not saying anything is proven, but there is still a lot of science that hasn't been bought by people who want capitalize on green energy, and calling man affected global warming a hoax is as bad as saying it's definitly man affected. There is no real place for extremism in real science, and the "hoax" position, as well as the "definitly man affected" positions are those extremes.
The truth is...you have no proof that anything is a "hoax" based on your thermometer, your reumatism, farmer's almanac, anti envoronmentalist web sites, or tree hugger web sites.
