THE GLOBAL WARMING TEST

Question 3:

The main cause of Global Warming is:

a) pollution from factories and automobiles
b) orbital eccentricities of Earth and variations in the Sun's output
c) the Greenhouse Effect

 That is correct!

How did you know that? Tom Brokaw or Dan Rather certainly didn't tell you. You are obviously up on your climatology!

Global Warming occurs in cycles caused mainly by changes in the sun's energy output and the sun's relative position to the earth.
