Ozone pollution has increased in Antarctica
Researchers reporting in ACS’ Environmental Science & Technology have analyzed more than 25 years of Antarctic data, finding that ozone concentrations near the ground arose from both natural and human-related sources.
Emissions of banned ozone-depleting substance back on decline
After a mysterious and sharp increase between 2012 and 2017 that could be traced to eastern China global emissions of a potent (and banned) substance notorious for depleting the Earth’s ozone layer – the protective barrier that absorbs the Sun’s harmful UV rays – have fallen rapidly in recent years and are now as low as never before since measurements began in this region in 2008, according to new atmospheric analyses published in “Nature” today.
