Bad news: anthropogenic CO2 affects climate.

Good news: observation indicates that every GCM overstates the effect. At this rate we're looking at +1 to +1.5C of forcing by 2100 which is literally nothing to worry about.

Observation trumps theory. Observation ALWAYS trumps theory. If you believe anything else you do not belong on /sci/ you belong on a religion board.

The maximum forcing for a doubling of preindustrial CO2 is +1.2C. That's stated right in the fucking IPCC reports.

The only way you can get +2-6C forcing is with a strong water vapor feedback.

Take a guess as to whether or not there's a strong water vapor feedback from this graph.

Anthropogenic CO2 has an effect but it's not one worth worrying about.
