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.
