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 same phenomenon that causes aurorae — the magical curtains of green light often visible from the polar regions of the Earth — causes mesospheric ozone layer depletion. This depletion could have ...

In 1974, scientists first sounded the alarm about the destruction of the ozone layer caused by human activities. Yet it would take several more years for the global community to reach a consensus on ...

The story of the ozone layer and its infamous hole is a roadmap for all of us. It offers a pathway for solving complex environmental challenges steeped in science, economics policy, skeptical ...

A new MIT-led study confirms that the Antarctic ozone layer is healing, as a direct result of global efforts to reduce ozone-depleting substances. Scientists including the MIT team have observed signs ...

The phaseout of CFCs under the Montreal Protocol successfully protected the ozone layer but led to substitute chemicals with unforeseen consequences. HCFCs and HFCs break down into trifluoroacetic ...

The ozone layer is healing, and it’s a symbol of hope around the power of human efforts. It sometimes feels like the only options we have in terms of news are “bad” or “worse.” But if you’re looking ...

The NOAA and NASA agencies have reported that the hole in the ozone layer above Antarctica is this year the fifth smallest since 1992. At its peak, it covered an average of 18.71 million square ...

The Antarctic ozone hole closed early in 2025 after one of the shortest seasons in decades, reflecting long-term recovery of the ozone layer.

“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 ...
