Supporters of global warming or climate change like to describe those who disagree with them as being members of the Flat Earth Society. Given the real, undisputed evidence I would like to ask who the real flat-earthers are.
The earth has existed for approximately 4.5 billion years. During this period of time the earth's climate has changed dramatically. The earth has been completely covered in ice at least twice and there have been periods when there were no polar ice caps. In the last 100,000 years there have been four Ice Ages, when much of North America was covered in ice. The most recent one ended approximately 10,000 years ago.
Between 1350 and 1850 the earth was in what is called the "Mini Ice Age," when much of Europe and North America had very short growing seasons, very long, cold winters and there was significant growth in glaciers. The earth's climate has constantly changed and man had absolutely nothing to do with these changes.
It would seem that supporters of global warming would have us believe the current climate of the earth is just right and it should never change. They believe that by controlling human activity they can prevent the forces of nature from changing the climate. It would also seem they believe the purpose of the earth is to provide mankind with a comfortable environment when the fact is, the earth's climate is going to be whatever nature wants it to be, without regard to man or global warming advocates.
They can not tell you what the climate should be. So, who are the true flat-earthers?
