There is some CO2-water vapor feedback. But it's not operating on a global scale. The modellers cannot accurately separate water vapour from the effects of clouds and rainfall.

I don't like to claim that I am an expert on anything, but I have enough knowledge about climate science and climate system to be able to write scientific papers and go to meetings and talk about monsoon systems and talk about any other things that you want to discuss about climate science issues. I'm as qualified as anybody that you know on this planet on this topic.

The hallmark of good science is the testing of a plausible hypothesis that is then either supported or rejected by the evidence.

I am a scientist. I go where the facts take me.

...a magical CO2 knob for controlling weather and climate simply does not exist!

The close relationships between the abrupt ups and downs of solar activity and of temperature that I have identified occur locally in coastal Greenland; regionally in the Arctic Pacific and north Atlantic; and hemispherically for the whole circum-Arctic, suggesting that changes in solar activity drive Arctic and perhaps even global climate.

Changes in solar activity have influenced what has been called the "conveyor-belt" circulation of the great Atlantic Ocean currents over the past 240 years.
