are climate change deniers naturally gullible?, page-108

bb, you haven't addressed the water vapour issue.

There can be no science in global warming, or climate change, discussions, unless we have firm data on the biggest greenhouse gas: affecting the warming by between three and eight and a half times that of CO2. So ignorant of water vapour are we that estimates of its content in the atmosphere vary between 2% and 4%.

Trying to scientifically analyse the effect of an increase in CO2 from 330ppm to 390ppm or450ppm is impossible. To claim that you can predict what will happen to the world as its result is just lying.

Then the warblists still need to explain the heating and cooling episodes during recorded history which happened during (or in spite of) minimal rises in CO2 levels.

Cheers, and hoping you had a Merry Christmas and have a great New Year.
