Role of CO2 in climate change questioned


CFCs to blame?

CFCs to blame?

It’s all one way traffic for the carbon dioxide mongers at the moment. Not only is the climate refusing to play ball, and the pesky media is starting to ask awkward questions of the alarmists, but a new paper hints at CO2 being less of a factor in climate change than CFCs.

From The Science is Settled department:

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.” (source – $)

Next step will be for the UN to tax underarm deodorants, I guess.
