Willie Soon quotes:

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 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.

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.

Too much ice is really bad for polar bears.

...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.

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.

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.

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

Science and its practice are no longer free and willing today but instead are constantly terrorized by research funding gravy trains and group thinking. This is why science needs defending and it takes courage to cleanse science from those cancerous elements and to bring her forward in its rightful place again. I am humbled and honored by this recognition.

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