Long, long ago in lands far away people believed the world was flat. The people were good catholic folks who were told that by their priests. The heathen Vikings were pretty sure it wasn’t. The Islamic scientists knew it wasn’t because of their great knowledge of science, in particular, mathematics and astronomy. Even after Columbus found the New World and Magellan’s ships sailed around it, many people clung to their flat Earth beliefs.

After our space capsule circled the moon and astronauts walked on it, lots of people still say it didn’t happen. Their belief is just as strong as the flat Earthers. Mounds of facts and seeing things with their own eyes can’t convince some people.

The same is occurring with Global Warming. The Earth is not only heating up but at a higher speed than any time in biologic and geologic records. Those records are like phony moon rocks to climate deniers. Even though they can see the effects and feel the warm winters they still can’t fathom the truth. Deniers use misinterpreted facts showing the warming is occurring but they can’t see it. One recent letter cited the minuscule amount of CO2 in the air and the amount of water vapor. Our atmosphere is a fine tuned balance of gases. The minuscule amount of carbon dioxide is the regulator for temperature. A tiny fraction up increases temperature and a tiny fraction down decrease it. It’s the difference between running the air conditioners year around or an ice age like 20,000 years ago. Another point was made of atmospheric water vapor increase as the cause is partially true because it is the result of the CO2 increase warming the oceans, melting the ice caps, and glaciers adding to the rise in temperature and violent swings in the weather. Just as predicted 150 years ago when its influence on climate was discovered.
