Researchers at Universidad de Santiago revealed that the extension of the hole in the ozone layer reached record levels in December
After four weeks of work in the Antarctica, Dr Raúl Cordero and Dr Alessandro Damiani, both researchers at the Department of Physics of Universidad de Santiago de Chile, were able to confirm that the extension of the hole in the ozone layer over the Antarctica reached more than 10 million km2 in December 2015, i.e. more than twice the average of that period in the past three decades.
