Some of the thinnest materials known to mankind may provide solutions to scientists in their quest to curb the effects of global warming.

Volcanic ash is no ordinary dust: It gets injected into the atmosphere, climbs to the stratosphere, impacts climate, powders roadways and clogs jet engines.

Using humidity-powered technology, researchers found several new ions that facilitate low-energy carbon sequestration.

New research suggests that ultrasound may have potential in treating a group of harmful chemicals known as PFAS to eliminate them from contaminated groundwater.

After sampling the skies over two Japanese mountains, scientists have found microplastics in the clouds.

As we hurtle toward crucial tipping points on a warming planet, an international team of scientists is recruiting a surprising ally to make a powerful dent in greenhouse gas emissions: the cow.

Significant quantities of microplastic particles are being trapped in riverbed sediments or carried through the air along major river systems, new research shows.

A groundbreaking study has provided pivotal new insights into the extensive impact of metal mining contamination on rivers and floodplains across the world.

The bright lights of big cities could be causing an evolutionary adaptation for smaller eyes in some birds, a new study indicates.

Though human-made ponds both sequester and release greenhouse gases, when added up, they may be net emitters, according to two related studies by Cornell researchers.
