We are already reaping the rewards of the Montreal Protocol, with the ozone layer in much better shape than it would have been without the UN treaty, according to a new study in Nature Communications.
Several decades ago, chlorofluorocarbons (CFCs) were chemicals used in hairspray, deodorants, foam products, air conditioners and more. In 1974 chemists Sherwood Rowland and Mario Molina published a paper that indicated ...
Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion.
Research from the University of Leeds and an international team of scientists has shown a recent increase in atmospheric hydrogen chloride (HCI), a substance linked to destruction of the ozone layer.
The production and consumption of chemical substances threatening the ozone layer has been regulated since 1987 in the Montreal Protocol. Eight international expert reports have since been published, which examine the current ...
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown source.
(Phys.org) —The total warming impact of 25 major synthetic greenhouse gases has been examined by an international team, led by researchers from the University of Bristol.
NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole.
A slowdown in global warming that climate sceptics cite in favour of their cause was partly induced by one of the world's most successful environment treaties, a study said on Sunday.
The new study by Prof. Sarah Kang from Ulsan National Institute of Science and Technology (UNIST), showed that the ozone depletion over the South Pole has affected the extreme daily precipitation in the austral summer, for ...
