Meteorological tsunamis, or meteotsunamis, are long ocean waves in the tsunami frequency band that are generated by traveling air pressure and wind disturbances. These underrated phenomena pose ...

The Trump administration has holistically reevaluated the government’s relationship—and how it responds to threats— to the health and welfare of its citizens. The past year was a shock to the U.S.

An American alligator surfaces in a Louisiana bayou. As apex predators, alligators shape wetland ecosystems through both trophic interactions and physical landscape ...

Scientists trekked across Icelandic lava flows that served as stand-ins for Venus’s volcanic landscapes, testing tools and ...

Snowpacks in places such as this windswept alpine pass in the Front Range of Colorado are difficult to characterize with current remote sensing methods because of cloud cover, complex topography, and ...

Clouds on Venus race across the sky at speeds of more than 100 meters per second, driven by incompletely understood atmospheric dynamics. Credit: Kevin M. Gill, CC BY 2.0 Imagine the catastrophic ...

Aurorae such as the southern lights, seen here over Antarctica, show the geomagnetic field in action. Some areas of the field, which shields Earth’s surface from charged solar particles, are stronger ...

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 ocean has helped mitigate global warming by absorbing around a quarter of anthropogenic carbon dioxide (CO 2) emissions, along with more than 90% of the excess heat those emissions generate. This ...

Two new studies investigate the possible origins of organic molecules detected in plumes erupting from the surface of Saturn’s moon Enceladus, pictured here in an artist’s impression. Enceladus’s ...

McDougall and Argall now report observations of a switchback-shaped structure in Earth’s magnetic field, suggesting that switchbacks can also form near planets. The researchers discovered the ...
