Smoke from major wildfires destroys the ozone layer

Journal Reference: Peter Bernath, Chris Boone, Jeff Crouse. Wildfire smoke destroys stratospheric ozone. Science, 2022; 375 (6586): 1292 DOI: 10.1126/science.abm5611 Atmospheric chemists from the University of Waterloo found that smoke from the Australian wildfires of 2019 and 2020 destroyed atmospheric ozone in the Southern Hemisphere for months. The ozone shield is a part of the … Read more

Chemical link between wildfire smoke and ozone depletion

Journal Reference: Susan Solomon et al. On the stratospheric chemistry of midlatitude wildfire smoke. PNAS, 2022 DOI: 10.1073/pnas.2117325119 Now, atmospheric chemists at MIT have found that the smoke from those fires set off chemical reactions in the stratosphere that contributed to the destruction of ozone, which shields the Earth from incoming ultraviolet radiation. The team’s … Read more
