First let me say that human originated global warming is largely BS. But currently CO2 is about 350ppm, in 1950 it was about 300ppm. That's an increase of 14.2% just there. We need to keep our facts straight or we're no more credible then the other side.

His facts are straight. The 14.2% increase is the total increase in atmospheric CO2 levels. The annual contribution of humans is 3.2%, but it has led to the 14.2% in total CO2 because of compounding. It's like interest in a savings account. Even with compounding, man-made CO2 has a negligible effect on the planet's temperature.

Where doe's it say the annual rate is 3.2%?

BTW 3.2% compounded over 20 years would be an increase of 87%. Far more then the actual case.

The real potential problem is the small warming caused by CO2 will cause increased water vapor levels which will in turn cause more warming. This feedback mechanism is further complicated by changes in cloud and snow/ice cover which have their own feedback effects.

Computer modelers can pull assumptions about these feedback levels out of their @#$% and get any answer they want.
