George Reisman :
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 atomosphere—up to 16 times the present level.George Reisman is a Pepperdine University Professor Emeritus.
This remarkable finding, along with others, was reported in the 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 [and warmista] propaganda machines, which brook no opposition. The article deserves to be required reading for everyone who is seriously interested in the subject of global warming.
The global warmistas advise: "In order to avert this catastrophe you must sacrifice your favorite goat".
