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.

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

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.

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.

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.

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