The way that the Petermann Glacier in Northwest Greenland is melting indicates that current models are too conservative. A glacier in the north of Greenland is melting faster and in a different way than scientists previously thought, and this has troubling implications for the future speed of global sea-level rise. The new discovery was published in the Proceedings […]
Bering Land Bridge was flooded until 35,700 years ago A new study shows that the Bering Land Bridge, the strip of land that once connected Asia to Alaska, emerged far later during the last ice age than previously thought. The unexpected findings shorten the window of time that humans could have first migrated from Asia […]
The ice shelf on Antarctica’s Pine Island Glacier lost about one-fifth of its area from 2017 to 2020, mostly in three dramatic breaks. The timelapse video incorporates satellite images from January 2015 to March 2020. For most of the first two years, the satellite took high-resolution images every 12 days; then for more than […]
The recent breakup of an Antarctic ice shelf is speeding up the ocean-bound descent of a glacier holding back at least a meter of sea level rise, according to new research. The findings may have implications for predicting when collapsing glaciers will raise sea levels and flood coastal cities. Pine Island, the focus of the study, […]
