the article was written by: Dr. Tim Patterson, professor in the Department of Earth Sciences at Carleton University, Ottawa, Canada. Professor Patterson specializes in Paleoclimatology. On July 1, this paper was released by the prestigious Geological Society of America (GSA) which is hardly a political organization. i don't believe much of what i read but i did find this to be an interesting part of the paper. Veizer and Shaviv conclude that 75% of the temperature variability in the last half-billion years is explained by cosmic ray changes as we move in and out of galactic spiral arms. Yet, over the same time frame, the geologic record shows essentially no correlation between CO2 levels and temperature even though CO2 levels have been up to 15 times higher than today (see graph below). In fact, CO2 concentration was more than ten times higher than current levels during the exceptionally cold Ordovician glaciation, about 440 million years ago. Contrary to popular conception, carbon dioxide appears to not be a significant climate driver at all. Yet the IPCC reports so confidently cited by Kyoto supporters assume that CO2 is a major driver of climate change while the effect of galactic cosmic ray flux variations are insignificant. The latest research shows this to be backwards. the data apparently just doesn't back up the alarmist scientists..
