Guess we may delay our leaf raking for a while since we are warned that the largest Ozone hole will happen in one or two weeks and we wouldn’t want to be exposed to too many of those deadly UV rays. But whoa, what happened to all that stuff we did? You remember the ozone hole panic, don’t you? And the urgency about reducing CFC’s in the environment, in aerosol sprays, replacing freon in our appliances and suchlike, so the ozone hole wouldn’t get larger and in hopes it might heal up? Did it help? Or was it all for nought? Could the consensus science have been so wrong? It seems it might have been.
A University of Waterloo scientist says that cosmic rays are a key cause for expanding the hole in the ozone layer over the South Pole — and predicts the largest ozone hole will occur in one or two weeks. Qing-Bin Lu, a professor of physics and astronomy who studies ozone depletion, said that it was generally accepted for more than two decades that the Earth’s ozone layer is depleted by chlorine atoms produced by sunlight-induced destruction of chlorofluorocarbons (CFCs) in the atmosphere. But more and more evidence now points to a new theory that the cosmic rays (energy particles that originate in space) play a major role.
What do you know! Cosmic rays. Wrong culprit. Imagine.
Lu said that data from several sources, including NASA satellites, show a strong correlation between cosmic ray intensity and ozone depletion. Lab measurements demonstrate a mechanism by which cosmic rays cause drastic reactions of ozone-depleting chlorine inside polar clouds.
Satellite data in the period of 1980-2007, covering two full 11-year solar cycles, demonstrate the significant correlation between cosmic rays and ozone depletion. …[link to source]
Well, all that effort and expense and hype and worry for nothing. Of course, consensus science has come a long way since then. Or has it?
Oh, we think it is safe to rake anyway- the ozone hole at issue is over the south pole.
Meanwhile Arctic sea ice is returning full force.
Of course it could change.
But we predict an early snowfall. Better get after those leaves.
