Ozone layer repairing, redirecting wind flows, new study says

The world has some good news to look forward to amid the novel coronavirus outbreak: a hole in the ozone layer is in recovery.

According to New Scientist, a hole in the ozone layer above Antarctica has continued to recover, leading to changes in atmospheric circulation.

The ongoing recovery has, according to ScienceAlert, stopped many dangerous changes in the Southern Hemisphere’s atmosphere.

In the late 1980s, ozone depletion was driving southern air currents further south, causing a change in rainfall patterns and ocean currents, the publication reports.

The changes suggest the 1987 Montreal Protocol, which banned the production of ozone-depleting substances, is finally working.

New satellite observations and climate simulations, shared in a Science Daily research paper on Wednesday, show that the changing wind patterns have led to the ozone layer’s recovery, according to Antara Banerjee of the University of Colorado Boulder and her colleagues.

Banerjee added that the ozone layer is expected to fully recover to 1980s levels by the 2030s in the Northern Hemisphere and by the 2050s in the Southern Hemisphere. The particular Antarctic hole in question is expected to recover by the 2060s.
