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...

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

Dozens of nations signed an agreement nearly 30 years ago to stop the expansion of a massive hole in Earth's ozone layer. Today, thanks to the Montreal Protocol, the hole in the ozone layer has shrunk as countries reduced,...

Nearly 30 years ago, almost every country in the world signed the Montreal Protocol to ban chlorofluorocarbons (CFCs) used in refrigerators, aerosols, and dry cleaning...

As if global warming isn't bad enough, scientists have discovered that a new category of uncontrolled chemicals are depleting the ozone layer and affecting the Earth’s climate...

Data from NASA shows that this year's hole in the ozone layer above Antarctica remains largely unchanged. On September 9, 2014, it measured 24.1m square km, which is roughly the size of North America; only a little smaller...

Good news, everyone - a new United Nations report shows that the Earth's ozone layer has increased for the first time in 35 years. The report credits the recovery in part to the phasing out of chlorofluorocarbons (CFCs) following...

A global treaty to eliminate harmful chemicals and protect the ozone layer has paid off. We need to take the same decisive action on fossil fuelsSometimes things dont go, after all, from bad to worse, wrote the poet Sheenagh...

Since the famous Montreal Protocol banning CFC's and HCFC's was signed in 1987, the public seems to have largely forgotten about the hole in the ozone layer over Antarctica...

From Penn State UNIVERSITY PARK, Pa. — Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers...
