In the last 500 million years, there have been two ice ages at the same time that vastly higher carbon dioxide levels prevailed in the earth’s atmosphere — up to 16 times the present level.
This remarkable finding, along with others, was reported in yesterday’s (November 7, 2006) New York Times. For details, see the article by William Broad, In Ancient Fossils, Seeds of a New Debate on Warming.
The article contains references to the work of a number of important scientists who aren’t supposed even to exist, according to the environmentalist propaganda machine, which brooks no opposition. The article deserves to be required reading for everyone who is seriously interested in the subject of global warming.
