Remember the big scare of the 1980s, when we were told that between all the fluorocarbons in products like hairspray and deodorant, a big hole was developing in the Ozone layer and the entire population of the world was about get cancer at the very same time? Good News! After taking fluorocarbons out of our products the holes in the Ozone layer over the Artic and Antarctic are closing. But have no fear the Ozone environmentalists haven’t lost their life’s mission, they can just become global warming moonbats. A new study claims that by closing the Ozone hole we are increasing global warming.
It turns out that the hole led to the formation of moist, brighter-than-usual clouds that shielded the Antarctic region from the warming induced by greenhouse gas emissions over the last two decades, scientists write in Wednesday’s issue of Geophysical Research Letters.
“The recovery of the hole will reverse that,” said Ken Carslaw, a professor of atmospheric science at the University of Leeds and a co-author of the paper. “Essentially, it will accelerate warming in certain parts of the Southern Hemisphere.”
The hole in the layer, discovered above Antarctica in the mid-1980s, caused wide alarm because ozone plays a crucial role in protecting life on Earth from harmful ultraviolet radiation.
The hole was largely attributed to the human use of chlorofluorocarbons, chemical compounds found in refrigerants and aerosol cans that dissipate ozone. Under an international protocol adopted in 1987, many countries phased out the compounds, helping the ozone to start reconstituting itself over the Antarctic.
For their research, the authors of the new study relied on meteorological data recorded between 1980 and 2000, including global wind speeds recorded by the European Center for Medium-Range Weather Forecasts.

The data show that the hole in the ozone layer generated high-speed winds that caused sea salt to be swept up into the atmosphere to form moist clouds. The clouds reflect more of the sun’s powerful rays and help fend off warming in the Antarctic atmosphere, the scientists write.
But before you try and add fluorocarbons to your hairspray to save the world, not all scientists agree with the new study.
But Judith Perlwitz, a University of Colorado professor and a research scientist at the National Oceanic and Atmospheric Administration, said that although the paper’s data were sound, she questioned the conclusions.
Even as the ozone layer recovers, greenhouse gas emissions are expected to expand, she said. She predicted that the rise in temperatures would cause wind speeds to increase over time and have the same cloud-forming effect that the ozone hole now has.
“The question is whether the wind is really going to slow down, and that I doubt,” she said.
“The future is not just determined by the recovery of the ozone hole,” she said. “We’re also increasing our use of greenhouse gases, which increases the speed of the winds all year long.”
There is even one scientist who published a study saying, as the Ozone layer closes, the planet will cool. Qing Bin-Lu, a professor of physics and astronomy at Canada’s University of Waterloo took a look at the interaction between cosmic rays and chlorofluorocarbons and predicts that global warming has disappeared, maybe for the next 50 years
This peer-reviewed paper was published in the prestigious online journal Physics Reports, Lu, who holds a Ph.D. in physics from the University of Newcastle, reports that CFCs, the compounds once widely used as refrigerants, and cosmic rays, which are energy particles originating in outer space, are mostly to blame for climate change, rather than carbon dioxide (CO2) emissions.
Lu says the world has been cooling since 2002
“the observed data show that CFCs conspiring with cosmic rays most likely caused both the Antarctic ozone hole and global warming. These findings are totally unexpected and striking, as I was focused on studying the mechanism for the formation of the ozone hole, rather than global warming.”
..Most remarkably, the total amount of CFCs, ozone-depleting molecules that are well-known greenhouse gases … decreased around 2000.Correspondingly, the global surface temperature has also dropped. In striking contrast, the CO2 level has kept rising since 1850 and now is at its largest growth rate.”
