Misperception # 1 Posted 03.29.10
The amount of CO2 generated from fossil fuel consumption by humans over the last century is far too small to significantly affect the Earth's climate. This misperception took the form of the following statement in a recent letter to the Atascadero News:
Only 1 molecule out of every 10,000 in the atmosphere represents CO2 added due to fossil fuel combustion in the last 100 years. ("Pennies" were used to illustrate this point in lieu of "molecules").

Water vapor is a more important greenhouse gas than carbon dioxide and therefore concern about carbon dioxide is misplaced.

Climate scientists are evenly divided about whether:
a) The Earth has been warming over the last several decades
b) Human activities play a major role in this warming

Volcanoes produce more CO2 than human activities.

All the climate scientists predicted a coming ice age just 40 years ago, but now they are all telling us that the Earth will be getting dangerously warm. Why should we believe them now?

A common fallacious argument is that Norse settlements in Greenland about 1000 years ago show that present global warming is just due to natural causes. The archeological and physical scientific evidence is discussed in detail to explain why this argument is, in fact, fallacious.
