The Antarctic ozone layer is currently healing, as a result of global efforts to reduce ozone-depleting substances.

In 1985, scientists discovered a seasonal hole in the Antarctic ozone layer. This protective layer shields Earth from harmful ultraviolet radiation. The sudden depletion raised global concerns, as ...

Much of the nitrous oxide entering the atmosphere from the oceans could be formed by a previously unknown inorganic route.

New research conducted by the Massachusetts Institute of Technology, with NASA's support, shows that human-caused damage is gradually being mitigated—the ozone layer is returning to its original state ...

While methane is a potent greenhouse gas that contributes to global warming, it also has complex chemical interactions in the atmosphere that can affect ozone levels. Understanding these dual ...

As the Vienna Convention turns 40, it is important to recognise there is still work to do to protect our planet’s UV shield.

While methane is a potent greenhouse gas that contributes to global warming, it also has complex chemical interactions in the atmosphere that can affect ozone levels. Understanding these dual ...

Feb. 3, 2025 — Long-term exposure to PM2.5, PM10, NO2 and ozone (O3) air pollution is associated with more hospital admissions for lower respiratory tract ... Jan. 7, 2025 — If you like the ...

The ozone layer acts as Earth's protective shield, blocking harmful ultraviolet radiation. While international efforts have ...

Although HFCs don't cause any ozone layer depletion, they turned out to be potent greenhouse gases. "In the end, scientists discovered that 1 kg of fluoroform—a once commonly used HFC—emitted ...

March 22 marks the 40th anniversary of the Vienna Convention for the protection of the ozone layer. This international agreement laid the foundation for the global protection of the stratospheric ...
