THE GLOBAL WARMING TEST

Question 4:

The Greenhouse Effect is caused primarily by:

a) water vapor
b) carbon dioxide
c) ozone-destroying aerosol sprays

 Sorry.... that is incorrect.

Over 95% of the Greenhouse Effect is caused by atmospheric water vapor inhibiting the escape of radiant heat from earth's atmosphere. The remaining 5% is caused by so-called greenhouse gases like methane and carbon dioxide, most of which comes from nature.

Aerosol sprays have been linked to ozone destruction in the upper atmosphere, but are not related in any way to the greenhouse effect.

 

Did you know. . .

The world's natural wetlands produce more greenhouse gas contributions annually than all human sources combined.
