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 […]

Credit: Contains modified Copernicus data (2020), processed by ESA ENLARGE This series of four Copernicus Sentinel-2 images captured between June 29 and July 24, 2020, shows a segment of the largest ice shelf in the Arctic break up and shatter into a flotilla of small icebergs totaling an area of […]

Lake Imja near Mount Everest in the Himalaya is a glacier lake that has grown to three times its length since 1990. Credit: Planetary Science Institute/Jeffrey S. Kargel In the largest-ever study of glacial lakes, researchers using 30 years of NASAsatellite data have found that the volume of these lakes worldwide […]

Franz Josef Glacier in New Zealand. Credit: Vaido Otsar Running through the heart of New Zealand’s glacier country is the infamous Alpine Fault. The 600 kilometer-long (370 mile) faultline on the boundary of the Eurasian and Pacific tectonic plates beneath the country’s South Island produces infrequent but significant earthquakes. In the line […]

A surging glacier in the St. Elias Mountains, Canada. Credit: Gwenn Flowers New model answers longstanding question of how these sudden flows happen; may expand understanding of Antarctic ice sheets. About 10 percent of the Earth’s land mass is covered in glaciers, most of which slip slowly across the land […]

Denman Glacier, February 26 – 28, 2020. Using a combination of satellite sensors, scientists recently found that Denman Glacier has been retreating both above and below the water line. That one glacier in East Antarctica holds as much ice as half of West Antarctica, so scientists are concerned about its […]
