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

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.

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.

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

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