Prominent climatologists like Dr. Richard Lindzen of MIT and Dr. Patrick Michaels of the University of Virginia contend that we would do well to carefully consider what the greater body of scientific evidence has to say on the matter of global warming before taking drastic measures. Their concerns are shared by other scientists who are troubled that the issue of global warming seems driven more by politics than by sound science . Geologic history clearly shows that Earth's climate is dynamic and ever-changing. While carbon dioxide as a constituent of Earth's atmosphere has been increasing since the industrial revolution, it has been similarly increasing since the earth started warming 18,000 years ago. Clearly, there are natural forces at work.
All sides agree the subject of climate change is a complex one.
Prudent science maintains that in our pursuit to understand our climate future we must also understand Earth's climate past.
