Blockbuster Peer-Review Study Set To Shake Global Warming Debate: Planetary temps control CO2 levels — not humans — Man-made emissions don’t control temps or global CO2 levels
'Over the last two years atmospheric physicist Salby has been looking at C12 and C13 ratios and CO2 levels around the world, and has come to the conclusion that man-made emissions have only a small effect on global CO2 levels. Salby does not dispute that some of the rise in CO2 levels is due to man-made emissions, but found that temperature alone explains about 80% of the variation in CO2 levels'
