If we would stop producing CO2 tomorrow the global mean temp would still rise at least one degree celsius till the end of the century (
http://www.ipcc.ch/). The most extreme simutlation result predicts an increase with around ten degrees. One degree is highly problematic (radical northern icecap reduction, sealevels increase by some cm, polar bears extinct). 10 degress is catastrophic (radical southern icecap reduction, sealevels increase by around 5 meters, all coastal regions in the world=New OrleansX10).

You seriously dont understand how science works. Complete consensus is never achieved, for fuck sake, some scientists believed that the moon was made of quicksand and that a lunar landing was impossible. The majority of scientists is the best guess you have, and if you dont want to act on their warning, then move to fucking krypton.
