Researchers on March 18 reported that the "black summer" fires in Australia in 2019 and 2020 damaged portions of the Earth's protecting ozone layer. The researchers said the damage was severe enough to be detectable by instruments, but not significant enough to have any immediate effect. However, they warned that the hole could grow larger as greenhouse gas emissions increase over time. They also pointed out that the damage would affect weather patterns around the world for years to come.
The study is being widely reported, including in news sources like USA Today (March 19), ABC News (March 19), National Public Radio (March 20), BBC News (March 21), and others. Some articles discuss how it might even impact climate change predictions.
