Efek rumah kaca (greenhouse) sebagian besar disebabkan oleh uap air, bukan dari CO2:

Water vapor accounts for about 70% of the greenhouse effect with carbon dioxide somewhere between 4.2% and 8.4%. Water vapor, a potent green house gas, averages 25,000ppm of the lower atmosphere compared to CO2 which is only about 360 ppm. TheAtmospheric CO2 change is only about +60 ppm. Realize that we are talking about a change in CO2 from 0.030% to 0.036% or a 0.006% change as a percentage of theatmosphere. The global warmers don't use these numbers instead 'warmers' say it increased 30% (for maximum rhetorical effect?). Over the same periods specific humidity has increased several percent and could be a change of 25,000ppm to 26,250ppm or 2.5% to 2.6% or a 0.1% change. This change in water vapor (probably due to irrigation) is about 16 times larger than the change in CO2 near the ground. (remember in the stratosphere is possibly cooling and has very little water vapor).

Hmm, nampaknya pengaruh CO2 sedikit saja
