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.

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

The warming we've experienced in the late 20th century could just as easily be explained by small decreases in cloud cover - natural changes in the system - and have nothing to do with CO2.

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

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.

Changes in clouds and rainfall can overwhelm what little effect CO2-water vapour has on temperature.
