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. — Willie Soon Copy Share Image
The hallmark of good science is the testing of a plausible hypothesis that is then either supported or rejected by the evidence. — Willie Soon Copy Share Image
Science and its practice are no longer free and willing today but instead are constantly terrorized by research funding gravy trains and group thinking.… — Willie Soon Copy Share Image

...a magical CO2 knob for controlling weather and climate simply does not exist! — Willie Soon Copy Share Image
There is no experimental data that exists that supports the view that the Earth's climate is changing in any dangerous way. — Willie Soon Copy Share Image
The close relationships between the abrupt ups and downs of solar activity and of temperature that I have identified occur locally in coastal Greenland;… — Willie Soon Copy Share Image

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. — Willie Soon Copy Share Image
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… — Willie Soon Copy Share Image
Changes in clouds and rainfall can overwhelm what little effect CO2-water vapour has on temperature. — Willie Soon Copy Share Image
