Something Strange Is Happening to the Ozone Layer North of Alaska — Scientists Are Watching

Something strange can happen high above Alaska and the Arctic.

In 2020, scientists recorded unprecedented ozone loss across the northern polar region, with parts of the atmosphere dropping below the threshold commonly used to define the Antarctic ozone hole.

In this DiscoverTube investigation, we look at why the Arctic ozone layer can suddenly thin, how polar stratospheric clouds and chlorine chemistry drive the process, and why scientists are still monitoring the skies north of Alaska so closely.

The ozone layer is recovering.

But under the right atmospheric conditions, extreme seasonal losses can still happen.
