Large Climate-Induced Changes in Ultraviolet Index and Stratosphere-to-Troposphere Ozone Flux

Large climate-induced changes in ultraviolet index and stratosphere-to-troposphere ozone flux

Now that stratospheric ozone depletion has been controlled by the Montreal Protocol, interest has turned to the effects of climate change on the ozone layer. An atmospheric chemistry model suggests that climate change will increase the stratosphere-to-troposphere ozone flux by 23% globally between 1965 and 2095, altering the amount of ultraviolet radiation reaching Earth’s surface. Now that stratospheric ozone depletion has been controlled by th…

The threat detected in Antarctica in 1985 led to a historic response but its complete recovery is still far away and depends on sustained commitment

40 years after a chilling discovery: What happened to the hole in the ozone layer?

Located in the stratosphere, the ozone layer blocks potentially harmful ultraviolet energy from reaching our planet's surface.

40 Years After the Chilling Ozone Hole Discovery: Scientists Unveil Eye-Opening New Details

It has been 40 years since scientists revealed the shocking discovery of a large hole in the ozone layer above Antarctica, a finding that sparked urgent global action to protect the planet’s fragile shield. This layer in the stratosphere acts as Earth’s natural sunscreen, absorbing harmful ultraviolet (UV) rays that can cause serious health issues such as skin cancer, DNA damage, and cataracts, as well as disrupt ecosystems. Drawing on research …
