Low Temperature Leads to a Hole in Ozone Layer above the Arctic

Briefed by | Published on 2020-04-09
A rare hole has opened up in the ozone layer above the Arctic, scientists using data from the copernicus sentinel-5P satellite have noticed a prominent reduction of ozone concentrations. Depletion over arctic is much larger than the previous years. The hole is not expected to pose any danger to humans unless it moves further south such as southern Greenland. The people of populated areas would be at increased risk of sunburn. However, on current trends the hole is expected to disappear altogether in a few weeks. It is too early to say whether this depletion is linked to Covid-19 lockdown that have radically cut down the air pollution.
