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 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.

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

Cord blood stem cell units have been shown to be a suitable alternative to adult bone marrow for the treatment of many diseases, including sickle cell anemia.

When I go to the beach, my grandchildren try to make words out of the veins in my legs. That's why I still take the pill; I don't want any more grandchildren.
