A new NASA climate simulation suggests that extremely large volcanic eruptions called “flood basalt eruptions” could significantly warm Earth’s climate and devastate the ozone layer…
Air pollution heating up the Southern Ocean. According to new research, a lesser-known form of ozone is playing a significant role in heating the Southern…
Ozone in the atmosphere found to have weakened one of Earth’s main cooling mechanisms. According to new research, ozone may be weakening one of the…
If wildfires become larger and more frequent, they might stall ozone recovery for years. The Australian wildfires in 2019 and 2020 were historic for how…
New CU Boulder study shows iodine from desert dust can decrease ozone air pollution but could prolong greenhouse gas lifetimes. When winds loft fine desert…
Ozone 101 is the first in a series of explainer videos outlining the fundamentals of popular Earth science topics. Let’s back up to the basics…
The 2021 Antarctic ozone hole reached its maximum area on October 7 and ranks 13th-largest since 1979, scientists from NASA and NOAA reported on October…
January 1 – October 7, 2021 A colder than usual winter atmosphere over the Southern Hemisphere led to a deep and larger-than-average ozone hole in…
World governments agreed in the late 1980s to protect Earth’s ozone layer by phasing out ozone-depleting substances emitted by human activities, under the Montreal Protocol….
The same phenomenon that causes aurorae — the magical curtains of green light often visible from the polar regions of the Earth — causes mesospheric…
New study shows climate change is increasing ozone depletion over the Arctic. There is a race going on high in the atmosphere above the Arctic,…
When lockdowns during the coronavirus pandemic cut local nitrogen oxide emissions, the effect on ozone pollution was global and unexpectedly rapid. As the coronavirus pandemic…
Ozone is a pollutant at ground level, but very high in the atmosphere’s “ozone layer,” it absorbs damaging ultraviolet radiation. Past studies have examined ozone…
Ozone-depleting chemicals may spend less time in the atmosphere than previously thought. New results point to unexpected, illegal production of several CFCs in recent years….
On the fourth anniversary of its first-light measurements, we are taking a look at some of the critical data collected by NASA’s Stratospheric Aerosol and…
As atmospheric concentrations of CFC-11 drop, the global ocean should become a source of the chemical by the middle of next century. The world’s oceans…
Studies have shown that SARS-CoV-2 remains active on aerosols and surfaces for between several hours and several days, depending on the nature of the surface…
Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over the Antarctic is one of the largest and deepest in recent years….
