Giant ozone hole closed above the Arctic

Scientists from the World Meteorological Organization do not attribute the closure of the ozone hole over the Arctic to the effects of the COVID-19 pandemic.

In April, a particularly large ozone hole closed over the Arctic, the press office of the World Meteorological Organization (WMO) said on Friday, May 1.

According to WMO, in spring 2020, the ozone hole over the Arctic reached “unprecedented size”, bypassing the previous “record holder” – the ozone hole formed over the Arctic in 2011.

As Claire Nullis, the official representative of WMO, explained at a briefing in Geneva on May 1, the formation of such a large ozone hole was due to the constant presence of ozone-depleting particles in the atmosphere, as well as very cold winters in the stratosphere (a layer of atmosphere between 10 and 50 km from the surface).

When asked whether the closure of the ozone hole was associated with a reduction in atmospheric pollution during a coronavirus pandemic, Nullis stated that it “had nothing to do with COVID”.
