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

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.

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.

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

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

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