For decades, scientists have closely observed the ozone layer, which protects Earth from the sun's harmful ultraviolet (UV) radiation. This year, just in time for World Ozone Day, the European Union's Copernicus Atmosphere...

The authors write in this plain language summary: Changes in the output of the Sun are thought to influence surface weather and climate through a set of processes initiated by the enhancement of upper stratosphere (32‐48...

From Eurekalert! Public Release: 2-Jan-2019 PM 2.5 pollution is falling but ground-level ozone pollution is on the rise Harvard John A. Paulson School of Engineering and Applied Sciences In early 2013, the Chinese government...

Finally, some good news about the environment. Earlier this week, the United Nations announced in a report that the ozone layer is on the mend. If the current recovery rate continues, parts of the ozone could be fully repaired...

This year, the South Pole region of Antarctica was slightly colder than the previous few years, so the ozone hole grew larger. However, scientists from NASA have developed models to predict what the ozone layer would have...

From the University of Bristol The compound, carbon tetrachloride, contributes to the destruction of the Earth’s ozone layer, which protects us from harmful ultraviolet radiation...

Globally banned by the Montreal protocol in 1987 for their ozone-destroying properties, chlorofluorocarbon (CFC) chemicals are experiencing a comeback...

NOAA finds rising emissions of ozone-destroying chemical banned by Montreal Protocol Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required...

From IMPERIAL COLLEGE LONDON The ozone layer – which protects us from harmful ultraviolet radiation – is recovering at the poles, but unexpected decreases in part of the atmosphere may be preventing recovery...

From the “Montreal Protocol success is not weather, unless it is” department and NASA Goddard: Using measurements from NASA’s Aura satellite, scientists studied chlorine within the Antarctic ozone hole over...

Guest essay by Michael Wallace, Hydrologist The prevailing model of seasonal and long term global ozone depletion is grounded in a principal assertion that emissions of industrial refrigerants and propellants (also known...

While Australians take to home batteries in their droves, some say there are better ways to save the environment.

From NASA Goddard: Warm Air Helped Make 2017 Ozone Hole Smallest Since 1988 Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each September was the smallest observed...

Public Release: 14-Aug-2017 American Geophysical Union From Eurekalert WASHINGTON D.C. — The Montreal Protocol, the international treaty adopted to restore Earth’s protective ozone layer in 1989, has significantly...

From the AMERICAN CHEMICAL SOCIETY comes this counter-intuitive finding: During heat waves, urban trees can increase ground-level ozone Planting trees is a popular strategy to help make cities “greener,” both...
