Big Hole opens in ozone layer above the Arctic - is result of low temperatures in atmosphere and is expected to disappear - not related to the Covid-19 shutdowns

Record-size hole opens in ozone layer above the Arctic

Rare hole is result of low temperatures in atmosphere and is expected to disappear

......The hole is not related to the Covid-19 shutdowns that have drastically cut air pollution and reduced greenhouse gas emissions. It is also too early to say whether the unusually stable Arctic polar vortex conditions are linked with the climate crisis, or part of normal stratospheric weather variability.

Peuch said there were no direct implications for the climate crisis. Temperatures in the region are already increasing, slowing the depletion of ozone, and the hole will start to recede as polar air mixes with ozone-rich air from lower latitudes. The last time similar conditions were observed was in spring 2011.....
