Record depletion of Arctic ozone layer causing increased UV radiation in Scandinavia

Over the past few days, ozone-depleted air masses have extended from the north pole to southern Scandinavia, leading to higher than normal levels of ultraviolet radiation during sunny days in southern Finland. These air masses will move east over the next few days, covering parts of Russia and perhaps extend as far south as the Chinese/Russian border. Such excursions of ozone-depleted air may also occur over Central Europe and could reach as far south as the Mediterranean. Researchers say that the current situation in the Arctic ozone layer is unparalleled.
