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

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.

There is no experimental data that exists that supports the view that the Earth's climate is changing in any dangerous way.

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.

The climate system is constantly readjusting naturally in a large way - more than we would ever see from CO2. The CO2 kick [impact of CO2 emissions] is extremely small compared to what is happening in a natural way. Within the framework of a proper study of the sun-climate connection, you don't need CO2 to explain anything.

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.
