Mar 22, 2022 · Shanklin and colleagues Joe Farman and Brian Gardiner published their findings the following year, suggesting a link to a human-made compound called chlorofluorocarbons (CFCs), used in aerosols...

The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as …

Mar 5, 2025 · In 1985, scientists discovered a “hole” in the ozone layer over Antarctica that opened up during the austral spring, between September and December. This seasonal ozone depletion was suddenly allowing UV rays to filter down to the surface, leading to skin cancer and other adverse health effects.

Jan 13, 2016 · In 1974, a landmark paper showed that chlorofluorocarbons (CFCs) used in spray bottles destroy atmospheric ozone. The discovery earned Paul Crutzen, Mario Molina and F. Sherwood Rowland a...

Jan 4, 2018 · This study is the first to use measurements of the chemical composition inside the ozone hole to confirm that not only is ozone depletion decreasing, but that the decrease is caused by the decline in CFCs.

Jan 28, 2025 · In 1930, Thomas Midgley Jr., a mechanical engineer at General Motors, inhaled a lungful of chlorofluorocarbons (CFCs) and promptly blew out a candle.

Mar 5, 2025 · In 1985, scientists discovered a "hole" in the ozone layer over Antarctica that opened up during the austral spring, between September and December. This seasonal ozone depletion was suddenly...

Mar 7, 2025 · The Ozone Crisis And Recovery. This hole in the ozone layer over Antarctica was discovered in the mid 80s and quickly took the world by storm. The ozone layer is located in the stratosphere, and ...

6 days ago · CFCs are chemically stable, and when released into the atmosphere, they reach the stratosphere almost completely unbroken. When decomposed by ultraviolet light, they release chlorine atoms. It is...

5 days ago · The ozone hole is healing, thanks to global reduction of CFCs by Jennifer Chu, MIT News Boston MA (SPX) Mar 11, 2025 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 of ozone recovery in the past.
