Dr. William Happer: History Proves Climate Change Isn’t Driven by Fossil Fuels

Leading physicist and Princeton emeritus professor Dr. William Happer:

"If you look over the last 10,000 years... there have been many warmings and coolings similar to the one that we're in now."

"It's pretty clear that greenhouse gases don't have very much to do with these warmings."

"Nobody was burning fossil fuels in the year 1200, 1300, when the poor Greenlanders were frozen out."

"They did some pretty good farming in the southern parts of Greenland in the year 1000, the year 1100, but before long, it became just too cold to continue to do that."
