"Increasing wildfires in a warming world may slow the recovery of the ozone layer, according to new research.

Smoke from Australian wildfires two years ago had an impact on the layer that shields the Earth from harmful UV rays, satellite observations suggest.

The study found bushfires were so intense that smoke rose into the atmosphere, causing a set of chemical reactions leading to the loss of ozone.

The scientists calculated a total ozone loss of 1% within March 2020 alone."
