For decades, Antarctica seemed to defy global warming. Since satellites began monitoring the poles in the late 1970s, the ...
When polar ice sheets melt, the effects ripple across the world. The melting ice raises average global sea level, alters ocean currents and affects temperatures in places far from the poles. But ...
In 2026, the Arctic winter sea-ice extent (annual maximum extent ,note 1) reached the lowest value since satellite ...

Vital Arctic sea ice shrank to tie its lowest measured level for the winter, the season when ice grows, as a warming Earth shattered records across the continents. Subscribe to read this story ad-free ...
In recent years, scientists have shown that detecting changes in navigation signals from GPS and Galileo after they bounce off Earth’s surface (GNSS reflectometry, or GNSS-R) can deliver valuable ...
Scientists studying Antarctica say the region has experienced a dramatic decline in sea ice over the past decade, with recent ...
After 10 days with only the open ocean and the occasional iceberg at our sides, sailing into the sea ice felt like crossing into a whole new realm. By Raymond Zhong Reporting from the icebreaker Araon ...
