A new study reveals a concerning uptrend in the emissions of five ozone-depleting substances from 2010 to 2020, despite their production for most applications being prohibited by the Montreal Protocol. The release of these five chlorofluorocarbons (CFCs) partially stems from leakage during the produ
Thirty years after countries agreed to ease up on the use of chemicals damaging the ozone layer, there are promising signs that the ozone will be
A study finds that ozone-destroying CFCs banned in the 1980s are back in use, but it's not clear where or why.
Their power to dissolve the ozone layer shielding Earth from the sun prompted a worldwide ban, but scientists have revealed that some human-made chlorofluorocarbons have reached record levels, boosting climate-changing emissions. Despite being banned under the Montreal Protocol, the five chlorofluorocarbons (CFCs) measured increased rapidly in the atmos...
"We're paying attention to these emissions now because of the success of the Montreal Protocol," says Luke Western, lead author of the paper and a researcher at the National Oceanic and Atmospheric Administration's (NOAA) Global Monitoring Laboratory and the University of Bristol.
