Satellite imagery has revealed that two of the fastest-changing glaciers in Antarctica are fracturing and weakening faster than ever—the first step towards the glaciers disintegrating and causing sea levels to rise dramatically.


Using observations from ESA, NASA and USGS satellites, the researchers explored the Pine Island and Thwaites Glaciers in the Amundsen Sea Embayment: two of the most dynamic glaciers on the Antarctic continent, and those responsible for a substantial 5% of global sea level rise.

Together, the two glaciers form an area of flowing ice the size of Norway, and hold enough water to raise global sea levels by over a meter. Both have distinctly changed in morphology in recent decades along with

The Arctic is warming faster than any other region on the planet. As a result, permafrost that is thousands of years old is now being lost to erosion. As measurements gathered on the Lena River by AWI experts show, the scale of erosion is alarming: every year, roughly 15 meters of the riverbanks crumble away. In addition, the carbon stored in the permafrost could worsen the greenhouse effect.


Today, the permafrost soils found on the Arctic coasts of Canada, Russia and Alaska, frozen for thousands of years, are increasingly eroding away due to the effects of waves and river
