Years ago, scientists noted something odd: Earth’s Northern and Southern Hemispheres reflect nearly the same amount of sunlight back into space. The reason why this symmetry is odd is because the ...

The Trump administration announced today that the 1.5-million acre coastal plains in the Arctic National Wildlife Refuge will open for drilling. Here, caribou graze on the plain, with the Brooks Range ...

Ancient driftwood found in Stanton’s Cave, about 40 meters above the Colorado River in Grand Canyon National Park, Ariz., hinted at a catastrophic landslide occurring more than 50,000 years ago.

The rare earth element niobium was likely dragged to the surface as the supercontinent Rodinia broke apart more than 800 million years ago. Credit: Artem Topchiy/Wikimedia, CC BY-SA 3.0 For much of ...

Warm water flowing into fjords and beneath ice shelves will continue to be a prime cause of glacial melting as global temperatures rise. This melting will, in turn, contribute to sea level rise and ...

The figure depicts the hierarchy of different types of Earth System climate models. These vary in complexity (increasing from bottom to top) and in the kinds of compromises sacrificed to computation.

Stemflow, or the flow of water along the surface of a plant’s stem, has been a subject of inquiry in forest hydrology since the latter half of the 1800s given its relevance to water balance studies.

In this model, mantle plumes (yellow) rise from big lower-mantle basal structures (nicknamed BLOBs, in red). Mantle plumes influence volcanic activity at the surface, and the current position of the ...

As the global climate continues to warm, fire seasons have intensified, and large-scale wildfires have become more frequent in many parts of the world. Factors such as vegetation type, land use ...

Global river datasets represent rivers that flow downstream in single paths that follow surface elevation, but they often miss branching river systems found in areas such as floodplains, canals, and ...

Where do meteorites come from? A new analysis of 75 fall events suggests that meteorites with different geologies travel from different places in the asteroid belt, which separates Mars and Jupiter.
