how do agw believers explain this?, page-10

Think you are all missing something here.

Co2 is a tiny part of atmospheric gases.

78% Nitrogen

21% Oxygen

1% Greenhouse gases

Co2 is a tiny part 0.038% of 1%

0 to 4% Water vapor at an average temp.around 15oC.

Now according to the IPPC statement Co2 is increasing the temperature,If the temperature is increasing then water vapor has increased anywhere from 0 to 4%..there is no way of measuring this.

Now, since water vapor is a known Greenhouse gas what percentage of the perceived rise in temperature is due to water vapor and not Co2..??

Be interested to see anyone make a calculation here before I show mine....think about it.
