According to global warming theory, carbon dioxide emissions from burning fossil fuels are trapping heat in the upper atmosphere, inexorably warming the planet.
The theory ignored inconvenient facts:
• In the Medieval Warm Period (950-1250 AD), and the Roman Warm Period (250 BC-400 AD), there were no automobiles or factories, but temperatures were warmer than now.
• In geologic history, CO2 concentrations in the atmosphere were much higher, but temperatures often were lower. In the Late Ordovician Period, CO2 concentrations were 12 times higher than they are today. The Late Ordovician Period was an ice age.
• Vostok (Antarctica) ice core samples indicate temperature changes have preceded changes in CO2 concentrations by an average of 800 years. This couldn't happen if CO2 caused temperature changes.
• CO2 in the atmosphere has increased since 1998, but temperatures haven't.
Now a peer-reviewed study of NASA satellite data indicates the computer models warmists rely upon grossly exaggerate the amount of heat being trapped in the atmosphere.

Mr. Gore's alarmist predictions have proved false. Polar ice caps are larger. So is the polar bear population (and the scientist upon whom Mr. Gore relied for his claim that the polar bear is endangered is facing accusations of scientific misconduct). The rise in sea levels -- which has been going on since the end of the last ice age -- is slowing down.
