A new MIT-led study confirms that the Antarctic ozone layer is healing, as a direct result of global efforts to reduce ozone-depleting substances. https://phys.org/news/2025-03-antarctic-ozone-hole-global-reduction.html Earth Sciences Wed, 05 Mar 2025 11:00:11 EST news660387662 A new study published in the journal Atmospheric Chemistry and Physics reveals a 17-year delay in the projected recovery of the ozone layer since 2006, underscoring the need for enhanced global environmental policies and enforcement. https://phys.org/news/2024-12-ozone-recovery-delayed-years-feedstock.html Environment Tue, 10 Dec 2024 13:14:31 EST news653058865 In the final decades of the 20th century, stratospheric ozone depletion—often called, not quite accurately, the ozone hole—was a widespread concern. Halocarbons, including chlorofluorocarbons used as coolants in refrigerators and aerosol spray cans, were linked, beginning in the mid-1970s, to a severely thinning ozone layer. However, global efforts to reduce halocarbon use have since led to a slow but steady recovery of the stratospheric ozone layer. https://phys.org/news/2024-06-spillover-tropospheric-ozone-affecting-stratospheric.html Earth Sciences Mon, 17 Jun 2024 12:27:24 EDT news637846028 Climate scientists studying three decades of ozone measurements from seven satellites see a positive trend in global recovery thanks to international efforts to curb ozone-depleting substances. https://phys.org/news/2017-11-positive-trend-global-ozone-recovery.html Environment Wed, 15 Nov 2017 08:38:44 EST news429957513 Recent increases in an unregulated ozone-depleting substance, could delay recovery of Antarctic ozone levels by 5-30 years, depending on emissions scenarios. https://phys.org/news/2017-06-ozone-recovery-unregulated-chemicals.html Environment Tue, 27 Jun 2017 11:31:31 EDT news417781882 Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health. https://phys.org/news/2009-02-global-recovery-stratospheric-ozone.html Earth Sciences Wed, 04 Feb 2009 13:08:00 EST news152975254
