Microplastics are everywhere, but new research points to a need to standardize measurements of microparticles.

A recent study has uncovered compelling evidence suggesting that the climate effects of new particles in urban areas have been significantly underestimated. Particles play a crucial role in climate ...

Particles play a crucial role in climate regulation, influencing processes such as cloud formation and radiation balance. Traditionally, research in urban environments has focused largely on primary ...

Spacecraft burning up in the atmosphere are leaving behind metal particles. Scientists are racing to understand if that affects the climate. One risk is that these particles may spark rainbow-colored ...

Rising levels of carbon dioxide in our atmosphere aren’t just affecting climate on Earth — they could also make weather in space more dramatic, says new research. A team led by scientists from the ...

Humanity’s messy fingerprints, from disposable grocery bags adrift in the deepest oceanic trenches to microplastic-laced snowfall on the tallest mountaintops, litter Earth—and each contaminant poses ...
