Tree swallows in the northern U.S. and Canada face the greatest risk from climate change despite responding to temperature the same way as tree swallows in the southern U.S, according to a new study led by Cornell researchers that analyzed nearly 95,000 nests across five decades.

A slowing Atlantic Ocean current is projected to intensify powerful storms in California while reducing snowfall over Greenland, according to a new University of California, Riverside study. 

With an anticipated “super” El Niño looming, a new study led by UC San Diego’s Scripps Institution of Oceanography considers whether society could use a weather-altering technique as a tool to mitigate the floods, extreme heat and other events that El Niño would bring.

Forests are shaped by light competition. The trees that grow the tallest have access to the most sunlight, blocking the rays and rendering the shaded space around them inhospitable to shorter trees below. 

An MIT-led research program aimed at creating future microsystems capable of sustainably transmitting data with greater bandwidth and higher efficiency than is possible today has made several significant advances since it was established in 2022.

The ability of bacteria to remove pollutants from soil, water, mine waste and other environments could be supercharged by a ‘friendly’ compatible virus, according to a study led by Flinders University.

The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in the Earth’s protective layer of stratospheric ozone.

In the humid jungle of Vietnam, Natalia Ocampo-Peñuela and Monte Neate-Clegg spent hours patiently waiting to spot the rare “Halloween bird.” Officially known as the Collared Laughingthrush, this songbird has striking orange, silver, and black coloring and a distinct, singsong call.

The first study to directly attribute Antarctic glacier retreat to climate change shows Pine Island Glacier was pushed significantly further by human driven warming.

A landmark study used ancient reef cores to deliver insight into the reef's responses to sea-level shifts.
