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

 Sorry . . . that is incorrect.

The industrial revolution began 200 years ago. Global Warming started 18,000 years ago.

You didn't read the response to Question 1 very well, did you?

 

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