CFCs 'are the real culprit in global warming'

This is a truly remarkable paper.  This guy gets the sort of correlations Warmists can only dream of.  That he found CO2 to have zero predictive power over warming is not new but that he found his CFC index gave correlations above .90 more or less ends the discussion.  There is basically no room for anything else to have much effect.  As far as science is concerned this moves  the debate about what the climate drivers are onto a new plateau, a plateau with no room for CO2.  But the political gospel will continue, of course

BANNED aerosols that caused the ozone hole - not carbon dioxide - were responsible for global warming since the 1970s, according to published research from one of Canada's leading universities.

The research predicts global temperatures will continue to fall for the next 50 to 70 years and sea levels will rise for two decades before starting to retreat.

The peer-reviewed research by Qing-Bin Lu, a professor of physics and astronomy, biology and chemistry at Waterloo University, was published in the International Journal of Modern Physics B.

The findings of Professor Lu's paper - Cosmic-Ray-Driven Reaction and Greenhouse Effect of Halogenated Molecules: Culprits for Atmospheric Ozone Depletion and Global Climate Change - are at odds with the consensus view that climate change is driven by increasing concentrations of CO2 in the atmosphere.

Waterloo University said Professor Lu's research provided "new fundamental understanding of the ozone hole and global climate change". Critics said it might be "nothing more than coincidental correlation", but it warranted further study.

Chlorofluorocarbons are known to deplete ozone, but conventional thinking is the emission of human-made non-CFC gases such as carbon dioxide had mainly contributed to global warming.

"But we have observed data going back to the industrial revolution that convincingly shows that conventional understanding is wrong," Professor Lu said. "In fact, the data shows that CFCs conspiring with cosmic rays (solar activity) caused both the polar ozone hole and global warming."

By proving the link between CFCs, ozone depletion and temperature changes in the Antarctic, Professor Lu said he was able to draw almost perfect correlation between rising global surface temperatures and CFCs in the atmosphere. "The change in global surface temperature after the removal of the solar effect has shown zero correlation with CO2 but a nearly perfect linear correlation with CFCs," he said.

If correct, the theory would have dramatic implications for forecasting global climate change.

"Most conventional theories expect that global temperatures will continue to increase as CO2 levels continue to rise, as they have done since 1850," Professor Lu said. "My calculations of CFC greenhouse effect show that there was global warming by about 0.6 degrees C from 1950 to 2002, but the Earth has actually cooled since 2002. The cooling trend is set to continue for the next 50-70 years as the amount of CFCs in the atmosphere continues to decline."

Professor Lu said it had been known for some time that CFCs had a damaging effect on the atmosphere and "we've taken measures to reduce their emissions.

"We now know that international efforts such as the Montreal Protocol have also had a profound effect on global warming, but they must be placed on firmer scientific ground," he said.

Terry McMahon, dean of the faculty of science at Waterloo, said: "This study underlines the importance of understanding the basic science underlying ozone depletion and global climate change.

"This research is of particular importance not only to the research community, but to policymakers and the public alike."
