Global warming debate 'irrational'

much of the up-to-date research indicates that "changes in the brightness of the sun" are almost certainly the primary cause of the warming trend since the end of the "Little Ice Age" in the late 19th century. Human emissions of carbon dioxide (CO2), the gas of concern in most plans to curb climate change, appear to have little effect on global climate, he said.

"I think the proof in the pudding, based on what (media and governments) are saying, (is) we're about three quarters of the way (to disaster) with the doubling of CO2 in the atmosphere," said Patterson. "The world should be heating up like crazy by now, and it's not. The temperatures match very closely with the solar cycles."

Patterson explained CO2 is not a pollutant, but an essential plant food.

Billions of taxpayers' dollars are spent to control the emissions of this benign gas, in the mistaken belief that they can stop climate change, he said.

"The only constant about climate is change," said Patterson.

Patterson said money could be better spent on places like Africa.
