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.

Too much ice is really bad for polar bears.

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.

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.

...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.

I've always gravitated towards opera, and the Royal Opera House is quite possibly the greatest opera house on earth.

All encounters with children are touched with social embarrassment.
