Cosmic rays destroy the ozone layer?
Qing-Bin Lu, a physicist in Canada stated that new data gathered from satellites and ground-based stations support the idea that much of the destruction of Antarctic ozone involves the action of cosmic rays. This goes against the widely-accepted notion that the ozone layer is depleted via the action of direct sunlight.
He found a correlation between cosmic ray intensity and the fluctuation in ozone in the Antarctic (between latitudes of 60 and 90 degrees S) from one October to the next between 1990 and 2007.

“These correlations mean that nearly 100% of the ozone loss over Antarctica must be driven by cosmic rays,” he says, pointing out that the degree of variation of cosmic ray intensity and Antarctic ozone are very similar (both about 10%). “In other words, any non-cosmic-ray related mechanism, if it exists, must be a very minor or negligible effect.”
