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 Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests. The findings raise concerns that, in a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica, and this could trigger processes that […]
“Faster ice melting under global warming was the most likely cause of the directional change of the polar drift in the 1990s.” Since 1980, the planet’s north and south poles have moved roughly four meters in distance, and new research shows that shifts in the Earth’s rotational axis have accelerated since the 1990s as a […]
The loss of glaciers worldwide enhances the breakdown of complex carbon molecules in rivers, potentially contributing further to climate change. University of Alaska Southeast Professor of Environmental Science Eran Hood was part of an international research team led by the University of Leeds that has for the first time linked glacier-fed mountain rivers with higher […]
