A new study pieces together existing data sources in order to develop a detailed, dynamic picture of auto emissions.

In parts of the Midwest and Great Plains, feathery yellow goldenrod and stands of big bluestem sway alongside Indiangrass and other prairie plants, stretching up to eight feet tall.

New research led by scientists at UC San Diego’s Scripps Institution of Oceanography finds that the travel time of underwater sounds traveling across the Arctic Ocean can be used to precisely measure ocean temperature under the region’s sea ice, providing precious data on temperature variability in a rapidly changing environment that is remote and difficult to access.

At the top of the planet, the cap of sea ice across Arctic waters grows and shrinks with the seasons, usually reaching its annual maximum extent in March. In 2026, this peak occurred on March 15, when the extent reached 14.29 million square kilometers, matching the lowest maximum observed since satellite monitoring began in 1979.

The study, published today (30 March), was led by Dr Adriana Humanes, Newcastle University and Dr Juan Ortiz, Australian Institute of Marine Science (AIMS).

A newly developed plastic material of the same type as is used in baby diapers can collect clean and safe drinking water from the air.

Rivers are critical resources that affect everything from watersheds to agriculture to energy. 

A new study, led by researchers at Columbia University and Woods Hole Oceanographic Institution (WHOI), identifies a diverse set of molecules released by marine phytoplankton that fuel microbial life and help drive Earth’s carbon cycle. 

This winter was one of the warmest on record across the West; as a result, many snowy, alpine areas have seen bouts of winter rainfall where there would ordinarily only be snow.

Alaska’s glaciers respond to climate change by melting for three additional weeks with every 1 degree Celsius increase in the average summer temperature, data from satellite-mounted radars show.
