A study by an international team led by scientists at the University of East Anglia have identified four new man-made gases in the atmosphere, all of which are contributing to the destruction of the ozone layer. They also looked at air collected between 1978 and 2012 in unpolluted Tasmania. Brenninkmeijer, Paul J. Oram, Claire E.

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new study by researchers at NOAA and their colleagues shows. Even more unexpected was that the rate of decline slowed by 50% after 2012.
