Global warming caused by CFCs, not carbon dioxide, study says | Reuters
But the research is Canadian -- so all bets are off.
Extremely interesting but...
My eye sees a rise in average global temperature from 1950 to 1970. Not sure what the "solar effect" is he is referring to.
A correlation coefficient of 0.97 is suspect itself. I've never seen one that high in any of the much less complicated data I work with.
Lastly, CO2 is known to cause the "greenhouse effect". If increased CO2 in the atmosphere isn't causing the temperature to rise, then we need to explain why.
