Ozone hole above Antarctica continues to grow

From Morning Report, 6:47 am on 22 November 2023

New satellite measurements show the ozone hole above Antarctica continues to grow - although it's happening later in spring than it used to.

Otago University research says that the ban on chloro-fluoro carbons - or C-F-Cs - has been effective but something else, possibly climate change, is depleting the ozone layer.

The lead researcher, doctoral candidate Hannah Kessenich, says ozone holes result in extreme UV levels over Antarctica and affect the climate throughout the Southern Hemisphere.

Kessenich spoke to Corin Dann.
