Greenhouse gases comprise 2% of the entire atmosphere. Carbon dioxide is about 3.5% of the greenhouse gases and human produced CO2 is about 3.5% of that. That means that human are responsible for a little over .12% of greenhouse gases. Hugh and series!

hope it’s a REAL long term effect! I want to live a long time and breathing helps =P

Wow. The wackos simply refuse to admit that it is water vapor that is the largest contributor that causes the greenhouse effect and that higher % of clouds block more light / sun / thermal radiation which actually cools the earth.

Hmmm no science to back man made 'problem,' to regulate the amount of water vapor.

Darn, socialism hits another wall.
