New Study Found that the Largest-ever Arctic Ozone Hole is Closed.

The largest even ozone hole recorded over the Arctic.  Copernicus’ Atmospheric Monitoring Service (CAMS) said that the hole was formed not by human activity but a particularly strong Arctic polar vortex. However, last week CAMS announced that the hole has closed.

Noticeably, this ozone hole became the largest one ever recorded in the Arctic region spanning an area of over 620,000 square miles (or 997793.28 kms).

Furthermore, the scientists monitoring the progress on the hole claims that this recovery has nothing to do with the air quality changes. “COVID19 and the associated lockdowns probably had nothing to do with this,” claims the group.

CAMS said the hole had been caused by unusual weather patterns over the Arctic.

Particularly cold temperatures and powerful winds formed a “polar vortex”, creating the frigid conditions which led to vast ozone depletion.

“Although it looks like the polar vortex has not quite come to an end yet and will reform in the next few days, ozone values will not go back to the very low levels seen earlier in April,” the organization tweeted.

The CAMS scientists added: “This ozone hole was basically a symptom of the larger problem of ozone depletion, and closed because of local annual cycles, not long-term healing. But, there’s hope: the ozone layer is also healing, but slowly.”

Still, the hole was massive, most of the ozone typically found around 11 miles into the stratosphere was depleted, the group said. The last time such a strong chemical ozone depletion was observed in the Arctic occurred nearly a decade ago.
