Slashing greenhouse gas emissions is 'our best hope of preserving Antarctica,' said the lead author of a new study.
The new study, led by glaciologist Martin Siegert of the University of Exeter, finds that it is"virtually certain that future Antarctic extreme events will be more pronounced than those observed to date" as countries continue to burn fossil fuels at a pace incompatible with warming targets set by the Paris climate accord.
"Although it was so extreme, a formal attribution of the March 2022 event to human factors has not yet been conducted," the study adds."However, an attribution analysis of an earlier record-breaking heatwave, that affected the Antarctic Peninsula in February 2020 and led to the highest recorded temperature in the Antarctic mainland , concluded a likely significant contribution from fossil-fuel burning.
"Possibly the most recognizable extreme event that occurred in the atmosphere was the loss of stratospheric ozone, discovered above Antarctica in the 1980s," the study continues."This loss was caused largely by a particular class of chemicals: Chlorofluorocarbons . Whilst this event catalyzed rapid and effective policy action by the global community in the development of the Montreal Protocol , the effects of the 'ozone hole' are being felt decades later.
