Ross Salawitch is co-author on a study published today in Nature Communications: Climate change favours large seasonal loss of Arctic ozone

Research / 23 June 2021 /

There is a race going on high in the atmosphere above the Arctic, and the ozone layer that protects Earth from damaging ultraviolet (UV) radiation will lose the race if greenhouse gas emissions aren’t reduced quickly enough.

A new study from an international team of scientists, including AOSC Professor Ross Salawitch, shows that extremely low winter temperatures high in the atmosphere over the arctic are becoming more frequent and more extreme because of climate patterns associated with global warming. The study also shows that those extreme low temperatures are causing reactions among chemicals humans pumped into the air decades ago, leading to greater ozone losses.
