The reaction is enhanced in the presence of ice, found in clouds at the level of the ozone layer. Lu based his theory on measurements of cosmic rays and ozone made by NASA between 1980 and 2007.

Researchers say that banning chlorofluorocarbons (CFCs) in the 1989 Montreal Protocol means the ozone layer is now on the path to a complete recovery by 2045. Lead author Dr Paul Newman says ...

The ozone layer is depleted by chemical reactions, driven by solar energy, that involve the by-products of human-made chemicals. This diagram shows how the thickness of the ozone layer changes ...

Getty Images A Canadian scientist says he’s discovered a massive hole in the ozone layer over the tropical region of the planet that could impact 50 per cent of the world’s population.

The ozone layer is between 15 to 40 kilometres away from the Earth’s surface, which is perhaps a closer distance than what some may have initially guessed. This close proximity means that the ...

The Antarctic ozone hole is shown here, as it was measured on October 7, 2021. Also visible on the map are thin regions of the ozone layer farther north, in the mid-latitudes. (NOAA Climate.gov) ...

The ozone layer shields life on Earth. We’ll soon lose a key way to monitor its health NASA's Aura and Canada's SCISAT near the end of missions to monitor ozone-depleting substances ...

Hole in ozone is larger than ever and only getting bigger – and scientists don’t know why Ozone hole as of 2023 has surpassed its size of three years prior, scientists say ...

The ozone layer shields us from harmful ultraviolet rays of the Sun. And after the discovery in the 1970s that chloroflourocarbons, a group of man-made chemicals, were destroying it, we actually ...

A new animation film and video game have been released to engage teenagers in the need to protect the Earth’s ozone layer. That is the thin part of the atmosphere which screens harmful ...
