Fine particles (PM₂.₅) were associated with around 79,000 preventable deaths, followed by nitrogen dioxide (NO₂), ozone (O₃) and coarser particles (PM₂.₅-₁₀, particles with a diameter between 2.5 and 10 micrometres).

New research shows how climate change is reshaping protected area management, though more funding and scientific knowledge are needed to facilitate the process.

A Dartmouth study shows that annual rainfall in much of the world has consolidated over the past four decades into heavier storms with longer dry periods in between.

A major Atlantic Ocean current system that helps regulate Earth’s climate has been slowing for nearly two decades across a wide stretch of ocean, according to new research—potentially reshaping weather patterns across the globe.

Southern California has seen a spike in great white shark sightings amid a spate of unseasonably warm spring weather. 

A new study reveals how sulfur compounds are metabolized under oxygen-deficient conditions – and which microorganisms are responsible.

Soils are home to some of the most diverse animal communities on Earth. These animals – including nematodes, springtails, mites, earthworms, spiders and other arthropods – drive decomposition, regulate microbial communities and contribute to nutrient cycling.

While our emissions are trapping heat near the surface of the Earth, they are having the opposite effect in the upper atmosphere. 

Some Alaska cruises are skipping a popular excursion to Tracy Arm Fjord this year after a landslide-generated tsunami barreled through the narrow channel during peak season last August. 

What began as a doctoral project at the University of Michigan is now spreading like red clover across the Great Lakes region to help farmers improve their soil and prevent fertilizer from washing into waterways.
