The correlation between Cosmic Rays and Ozone.
Well at least some scientist see something in it.
The fact that scientist assumed it was the sun light directly and now considering external factors again tells us that they "know" that EXTERNAL factors to earth control one of our biggest regulator of climate
AbstractThis Letter reports reliable satellite data in the period of 1980-2007 covering two full 11-yr cosmic ray (CR) cycles, clearly showing the correlation between CRs and ozone depletion, especially the polar ozone loss (hole) over Antarctica. The results provide strong evidence of the physical mechanism that the CR-driven electron-induced reaction of halogenated molecules plays the dominant role in causing the ozone hole. Moreover, this mechanism predicts one of the severest ozone losses in 2008-2009 and probably another large hole around 2019-2020, according to the 11-yr CR cycle.
Do cosmic rays destroy the ozone layer?
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, says a physicist in Canada. This goes against the widely-accepted notion that the ozone layer — which shields Earth from harmful ultraviolet radiation — is depleted via the action of direct sunlight
