Urban vehicle emissions are a critical contributor to atmospheric pollution, impacting air quality, public health, and climate systems. While exhaust emissions—such as nitrogen oxides (NOx), ...

Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a potentially toxic "forever chemical" around the globe, a new study shows.

Extreme weather is intensifying across the globe, and the standard explanation points to greenhouse gas emissions warming the atmosphere. But a less examined dynamic may be compounding the damage: ...

In a paradox of air pollution, a decrease in man-made pollutants led to more methane in our atmosphere. And natural wetlands released more of the planet-warming gas at the same time ...

As the American Southwest grapples with unnaturally sky-high temperatures wrought by a destructive “heat dome,” scientists say carbon dioxide — a polluting greenhouse gas released by fossil fuels, ...

A new study has uncovered that the Erhai Lake Basin in southwest China is releasing far more atmospheric nitrogen pollution than it absorbs, raising concerns about regional air quality, ecosystem ...

"If we had a magic wand and could end emissions from agriculture and fossil fuel use and landfills, we would see the atmosphere return to normal within a decade or so," said Rob Jackson in his new ...

Thousands of satellites that disintegrate upon re-entry release aluminum into the atmosphere, disrupting polar winds and the ...

A key negative feedback in models of anthropogenic climate change is that more carbon dioxide in the atmosphere means ...

According to data from the United Nations Office for Outer Space Affairs, 2023 was a record year for launching satellites, probes, landers and more into space. But scientists worry those plumes of ...
