A 2016 study suggested tall ice cliffs along Antarctica’s coast might collapse rapidly under their own weight and contribute to more than 6 feet of sea-level rise by 2100. Now, MIT researchers have found this prediction may be overestimated.
The new rifts appeared soon after last year’s major calving of iceberg B46, which is about 3 times the size of New York’s Manhattan island. Satellite monitoring suggests a new iceberg of similar proportions will soon be calved.
A new study suggests that about 4,000 years ago, a combination of isolation, extreme weather, and the arrival of humans on Wrangel Island in the Arctic Ocean killed off Earth’s last population of mammoths.
