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.

Clear link between PFAS, BPA exposures and a prior cancer diagnosis found in large national study.

Spending days camping in a mosquito-filled swamp on the Indonesian island of Borneo, Alison Hoyt's goal was to measure methane emissions in tropical wetlands – one of the largest sources of the potent greenhouse gas.

A new study led by Cambridge University confirms that planting hedges between roadsides and school playgrounds can dramatically reduce children’s exposure to traffic-related particle pollution.

Some floods are so severe they rarely strike more than once a century, but rising seas could threaten coastal communities with yearly extreme floods.
