German scientist Markus Rex (Markus Rex) and his colleagues at the Institute for Polar and Marine Research Alfred Wegener (AWI) found that the destruction of the ozone layer over the Arctic is happening much faster than expected, due to the side effects of global warming.
If the upper layers of the Arctic atmosphere become cooler — is a consequence of climate change — then the rate of depletion of the ozone shield could be three times higher than generally assumed.
Rex learned the climatic conditions in the Arctic over the past ten years to figure out how the destruction of the ozone layer is dependent on the weather, and found that ozone loss is rigidly connected with the amount of polar stratospheric clouds.
These clouds are formed in the winter at an altitude of 20 kilometers, and sometimes at the flickering glow referred to as "pearl."
But these clouds exist not just for beauty — on the surface reactions occur chemicals, "eat up" the Earth's protective ozone.
Chemical reactions in the clouds convert chlorine industry to a reactive form that destroys ozone molecules. Simply put, the more clouds — more destruction of the ozone layer. Scientists will have to re-evaluate the extent of the problem, and this would be easy.
