Chlorofluorocarbons are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Physics B this week. This graph shows the predicted path of global temperatures is set to continue their decline as a result of depletion of CFC’s in the atmosphere.

CFCs, organic compounds with uses as refrigerants and solvents, are already infamous for causing environmental damage by contributing to ozone depletion, a discovery that led to the phasing out of CFC manufacturing via the 1987 Montreal Protocol. But a recent peer-reviewed journal has claimed that anthropogenic global warming is largely driven by Chlorofluorocarbons (CFCs), not carbon dioxide.“Conventional thinking says that the emission of human-made non-CFC gases such as carbon dioxide has mainly contributed to global warming. But we have observed data going back to the Industrial Revolution that convincingly shows that conventional understanding is wrong,” said Qing-Bin Lu, a professor of physics and astronomy, biology and chemistry in Waterloo’s Faculty of Science. “In fact, the data shows that CFCs conspiring with cosmic rays caused both the polar ozone hole and global warming." "Most conventional theories expect that global temperatures will continue to increase as CO2 levels continue to rise, as they have done since 1850. What’s striking is that since 2002, global temperatures have actually declined – matching a decline in CFCs in the atmosphere,” Professor Lu said. “My calculations of CFC greenhouse effect show that there was global warming by about 0.6 °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.”…Lu’s theory has been confirmed by ongoing observations of cosmic ray, CFC, ozone and stratospheric temperature data over several 11-year solar cycles. “CRE is the only theory that provides us with an excellent reproduction of 11-year cyclic variations of both polar ozone loss and stratospheric cooling,” said Professor Lu. “After removing the natural cosmic-ray effect, my new paper shows a pronounced recovery by ~20% of the Antarctic ozone hole, consistent with the decline of CFCs in the polar stratosphere.”By proving the link between CFCs, ozone depletion and temperature changes in the Antarctic, Professor Lu was able to draw almost perfect correlation between rising global surface temperatures and CFCs in the atmosphere.Needless to say, such a report is controversial to say the least. But the paper features “superior predictive capabilities, compared with the conventional sunlight-driven ozone-depleting and CO2-warming models."
