A new study reveals that chemicals used to replace ozone-damaging CFCs are now driving a surge in a persistent “forever ...

Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a ...

Methane comes in different isotopic signatures. Methane from fossil fuels like natural gas leaks or coal mines is heavier, ...

Tiny marine plankton that build calcium carbonate shells play an outsized role in regulating Earth’s climate, quietly pulling ...

Chemicals used in refrigeration break down in the atmosphere to produce trifluoroacetic acid, a persistent pollutant that ...

The chemicals that helped save the ozone layer may be quietly seeding the planet with an indestructible pollutant.

A new study out of York University has found that the amount of atmospheric trifluoroacetic acid (TFA), the tiniest forever ...

The relative size of a water droplet determines the kinetic processes that occur when ozone is taken up at the air-water ...

The findings highlight the complex link between atmospheric chemistry, climate, and human activity.

Concentrations of a forever chemical known as TFA is increasing in rainwater, drinking water, soil and plants.

Methane spiked in the early 2020s as wetter conditions boosted emissions at the same time the atmosphere’s chemical “cleaner” weakened.

Atmospheric methane rose faster than ever in the early 2020s, driven less by fossil fuels and more by changes in nature itself.
