“Actions taken under the Montreal Protocol continued to decrease atmospheric abundances of controlled ozone-depleting substances (ODSs) and advance the recovery of the stratospheric ozone layer.

It started with a simple challenge. Now a group from Auburn Junior High School is taking their project to a whole new level.

In the past decade, researchers found that the amount of ozone-depleting chemicals in both the lower and upper atmosphere reached a peak around the year 2000 and has been slowly declining. From the ...

One risk is that these new particles could seed polar stratospheric clouds, which are spectacular rainbow-colored clouds that can damage the ozone layer, experts told Business Insider.

Now in Geophysical Research Letters, Randel and colleagues report on coherent fluctuations in ozone concentrations and temperature in the tropical lower stratosphere 1 that are related to the near ...

Scientists are not sure how much metallic dust remained in the atmosphere after the most recent SpaceX rocket 'disassembly.' ...

Although they don't impact the surface directly, historical evidence and simulations suggest airbursts can pack a punch.

Aug. 2, 2024 — Scientists confirmed that much of ozone's increase in the upper troposphere is likely due to humans. A team detected a clear signal of human ... New Study Disputes Hunga Tonga ...

Modelled changes in stratospheric ozone concentration are shown, expressed as a percentage of 1980 values. Projected ozone varies depending on which Intergovernmental Panel on Climate Change (IPCC ...

With toxic smog choking cities worldwide and 99% of the population breathing unsafe air, 2025 must be the year for decisive ...

A strong polar vortex in the stratosphere has brought subzero temperatures to the Midwest, Mid-Atlantic and deep into the South.
