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").

 b) Human activities play a major role in this warming
