THE GLOBAL WARMING TEST

Question 8:

Which answer below provides the best explanation for the following temperature record?

Industrial pollution from factories, power plants, and cars caused global warming
Natural variations in global temperatures may occur in roughly 500-years cycles
Global cooling occurred as a result of the Renaissance Period

Sorry...that is incorrect.

Some of the warmest temperatures in the last 2000 years occurred during the Medieval Warm Period from 1000 to 1350 AD. Clearly industrial pollution was not the cause.
