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.
Thanks to abnormal weather patterns in the upper atmosphere over Antarctica, this year's ozone hole is the smallest since the ozone hole was 1st observed in 1982.
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.
Glaciers are melting in many places on Earth today. But glacier loss in the Peruvian Andes is happening particularly rapidly. New research reports a reduction of almost 30% between 2000 and 2016.
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.
On average the ocean is 2.3 miles (3.7 km) deep, but many parts are much shallower or deeper. In the deepest zones, life forms have adapted to live in the dark, under crushing water pressure.
Researchers have identified fossil remains as belonging to rauisuchians, predatory crocodile-like animals that fed on early dinosaurs and mammal relatives 210 million years ago.
In October 2019, the research icebreaker Polarstern will drop anchor at an ice floe in the northern Laptev Sea, to spend a year investigating Earth’s Arctic.
