A scientific paper published in 1985 was the first to report a burgeoning hole in Earth's stratospheric ozone over Antarctica. Scientists determined the cause to be ozone-depleting substances – long-lived artificial halogen compounds. Although the ozone-destroying effects of these substances are now widely understood, there has been little research into their broader climate impacts. A […]
Nature, Published online: 21 January 2020; doi:10.1038/d41586-020-00156-8 The good news: the worst ozone-depleting gases are already banned. Plus, top biologists name the technology to watch in 2020 and the alternative theories challenging the Big Bang.
A study examines the greenhouse warming effects of ozone-depleting substances and finds that they caused about a third of all global warming from 1955 to 2005, and half of Arctic warming and sea ice loss during that period.
Nature Climate Change, Published online: 20 January 2020; doi:10.1038/s41558-019-0677-4 Arctic warming is attributed to GHGs and feedbacks, but the specific contribution of ozone-depleting substances (ODS)—also potent GHGs—has never been quantified. Here, model simulations show that ODS may have contributed half of the Arctic warming during the period 1955–2005.
