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

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.

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

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.

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