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 ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...

“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.

The chemical reactions are as follows ... From the 1980s to the early 2000s, global levels of stratospheric ozone also dipped by 5% to 6%, but they have been rebounding slightly in the past few years.

Sep. 12, 2024 — Ozone gas is reducing the growth of tropical forests -- leaving an estimated 290 million tons of carbon uncaptured each year, new research ... Scientists Find a Human ...

Remember the ozone layer? If you were around ... with the sulfuric acid naturally present in the stratosphere to create a chemical reaction that can suck up passing water vapor, creating an ...

Way up in the stratosphere, ozone (O3) absorbs deadly radiation from the sun, protecting all life on Earth. But don’t get too close! If we breathe ozone, it irritates our tissues, potentially causing ...

reactions of polluted air with sea salt aerosol from the ocean can lead to high surface ozone levels that affect air quality. Chlorine has become infamous for its role in stratospheric ozone ...

N₂O is chemically inert, allowing it to rise into the stratosphere without being ... (NO), which then acts as a catalyst in reactions that convert ozone into other forms of oxygen.

The Earth’s atmosphere has six layers. In the second layer, the stratosphere, you can find the ozone layer, which is made up of a gas called (wait for it) ozone. Ozone molecules are formed of ...

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

Physical chemists aim to develop a fundamental understanding at the molecular and atomic level of how materials behave and how chemical reactions occur ... and how global phenomena such as the ...
