In the 1970s, the concentration of ozone (measured in Dobson units) started dropping, and scientists discovered that ...

But the longer the hole persists, the greater the likelihood that the ozone layer is dominated by natural factors, not human CFC emissions.” Another year has passed, and that stubborn Ozone Hole over ...

The ozone hole over Antarctica is the seventh smallest it’s been since the early 1990s. Recovery began with the Montreal Protocol, which ended the production of all chlorofluorocarbons (CFCs ...

A new study published in the journal Atmospheric Chemistry and Physics reveals a 17-year delay in the projected recovery of ...

As existing CFC levels gradually decline, ozone in the upper atmosphere will rebound globally, and ozone holes will shrink. “For 2024, we can see that the ozone hole’s severity is below ...

This year, however, two sudden atmospheric warming events in July disrupted the Polar Vortex and prevented the concentration of CFCs above the South Pole – leading to a smaller ozone hole.

As a result of the widespread use of CFCs in consumer products, the ozone layer became depleted, particularly through a phenomenon that most of us know as "the ozone hole." The word "hole" should not ...

The ozone hole above Antarctica has been remarkably massive and long-lived over the past four years and chlorofluorocarbons (CFCs) are not the only things to blame, said researchers in their study ...

Our use of ozone-depleting substances such as chlorofluorocarbons (CFCs) had torn a hole in the ozone layer that protects us from the sun’s harmful ultraviolet radiation. United Nations ...

But despite the decline in CFCs, there has not yet been a significant reduction in the area covered by the Antarctic ozone hole, according to the New Zealand researchers behind the study in the ...

But CFCs already in the air will take many decades ... Let’s back up to the basics and understand what caused the Ozone Hole, its effects on the planet, and what scientists predict will happen ...
