The United Nations commemorated the International Day for the Preservation of the Ozone Layer, on Wednesday, recognizing the success of landmark global agreements in helping restore the protective ...

In 1985, scientists “accidentally” discovered a yawning hole in the ozone layer above Antarctica. Initial research suggested the problem had emerged as recently as the late 1970s, but a new analysis ...

The ozone layer, Earth's invisible shield against harmful ultraviolet radiation, sits quietly in the stratosphere between roughly 15 and 35 kilometers above our heads. For decades, scientists watched ...

“In 2015, scientists at NASA predicted that the Ozone Hole would be half closed by 2020. That hasn’t happened. Other scientists have forecasted that the hole will not begin to disappear until 2040 or ...

The ozone layer is on track to heal within four decades, according to a recent UN report, but this progress could be undone by an upsurge in rocket launches expected during the same period. The ozone ...

The ozone layer is a part of Earth’s atmosphere that captures some of the Sun’s ultraviolet (UV) light emissions. When the ozone layer is compromised, its ability to absorb radiation weakens, allowing ...

The scope of the newly discovered hole in the ozone layer over Earth's tropics, revealed by the annual change in ozone levels and average annual temperatures. (Qing-Bin Lu) (CN) — As if we needed any ...

Earth’s protective ozone layer is slowly but noticeably healing at a pace that would restore the layer across much of the world by the 2040s, and would fully mend the hole over Antarctica in about 43 ...

Air pollution and iodine from the ocean contribute to damage of Earth's ozone layer. A new paper quantifying small levels of iodine in Earth's stratosphere could help explain why some of the planet's ...

The 1987 treaty that stopped the pollution causing a hole in the ozone layer is rightly seen as a major success story. It’s arguably the most successful international environmental agreement ever.
