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

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.

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.

Too much ice is really bad for polar bears.

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

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

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.

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

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