Ozone-depleting CFCs detected in historical measurements—20 years earlier than previously known
An international research team led by the University of Bremen has detected chlorofluorocarbons (CFCs) in Earth's atmosphere for the first time in historical measurements from 1951—20 years earlier ...

CFC replacements behind vast quantities of global 'forever chemical' pollution, research reveals
Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a ...
The ozone layer is a part of the Earth’s atmosphere that absorbs much of the sun’s harmful ultraviolet light. In 1985, researchers noticed that the ozone layer was growing thinner above the Antarctic.
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 ...
Local pollution cuts haven’t lowered ozone because transported pollution and global emissions now dominate exposure.
On 16 September, the world will mark the International Day for the Preservation of the Ozone Layer. It was on this day, 35 years ago, that the Montreal Protocol, considered one of the most significant ...
This map shows the size and shape of the ozone hole over the South Pole on Oct. 5, 2022, when it reached its single-day maximum extent for the year. Credits: NASA Earth Observatory image by Joshua ...
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 ...
No wonder politicians curse the environment. After intense horse-trading, arm twisting and agonizing, 93 industrialized nations agreed in 1990 to phase out by the year 2000 chemicals that destroy the ...
