Unlike CFCs the new compounds don't break down in the atmosphere but instead slowly build up in the Arctic and can enter food and water supplies ...

Around 2075, there will be a “reverse flux” of CFCs from the ocean into the atmosphere, says lead author Peidong Wang. Iceberg off the coast of Antarctica. Image by Rhett A. Butler.

Some CFCs are increasing in the atmosphere (Picture: Getty) The volume of five ozone-depleting CFCs in the atmosphere increased rapidly between 2010 and 2020, reaching a record high.

This finding was concerning because CFCs are the main culprits in depletion of the stratospheric ozone layer, which protects us from the sun’s ultra-violet radiation. Any increase in emissions of CFCs ...

In rare good news for the planet, the hole in the Earth’s ozone layer is on track to recover completely within decades as harmfule chemicals are phased out, according to a new UN-backed assessment.

CFCs’ contribution to global warming has been small. The atmospheric energy rise is the first step to warming. The atmospheric energy rise of CFCs since 1750 has been about 0.34 Watt/m2 .
