Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion.
Each year, ozone-depleting compounds in the upper atmosphere destroy the protective ozone layer, and in particular above Antarctica. The ozone layer acts as Earth's sunscreen by absorbing harmful ultraviolet radiation from ...
"Ozone depletion is a well-known phenomenon and, thanks to the success of the Montreal Protocol, is widely perceived as a problem solved," says University of East Anglia's David Oram. But an international team of researchers, ...
Recent increases in an unregulated ozone-depleting substance, could delay recovery of Antarctic ozone levels by 5-30 years, depending on emissions scenarios.
Even if there comes a day when the world completely stops emitting greenhouse gases into the atmosphere, coastal regions and island nations will continue to experience rising sea levels for centuries afterward, according ...
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.
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.
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.
