A hole in the ozone layer over Antarctica is one of the largest and deepest for years, researchers have warned. Scientists say the hole which forms annually over the South Pole is particularly concerning because last year’s was ‘unusually small and short-lived’.
The stratospheric ozone layer is damaged by chemicals used by humans which acts like a shield protecting humans from potentially harmful ultraviolet radiation. That causes a thinning in the layer, known as the ozone hole.
‘The 2020 ozone hole resembles the one from 2018, which also was a quite large hole, and is definitely in the upper part of the pack of the last 15 years or so.’
