Scientists are studying ice cores extracted from Tajikistan to determine why its glaciers have resisted the rapid melting seen almost everywhere else, and apply the potential answers elsewhere. https://www.japantimes.co.jp/environment/2026/01/14/climate-change/hokkaido-university-ice-glaciers-research/?utm_medium=Social&utm_source=mastodon #environment #climatechange #hokkaidouniversity #climatechange #glaciers

Sentinel-1's decade of essential data over shifting ice sheets

Ice velocity is a key parameter in measuring the effects of #ClimateChange. The speed at which #glaciers and #IceSheets move tells us the rate at which they discharge ice and water into the sea, feeding into estimations on future #SeaLevelRise. Data on ice velocity also help to keep track of the break-up of ice sheets, such as calving events or damage to the ice sheets.
Since its first satellite was launched in 2014, the #Copernicus #Sentinel1 mission has provided a step change in the capabilities of polar satellite Earth observation. Its 12-m-long advanced #SAR instrument works in C-band. This makes it a reliable tool for acquiring high-resolution imagery for continuous monitoring and emergency response efforts. It is able to capture data through cloud cover, smoke and during lack of sunlight.

The data visualization of Antarctica (see image below) shows details of ice flows moving at speeds between 1 m and 15 m per day. The Sentinel-1 data is averaged over the period 2014–2024. Regions shown on the map include the Antarctic Peninsula and Alexander Island, as well as large parts of the West Antarctic Ice Sheet and East Antarctic Ice Sheet. Most of the coastal areas were captured at either six or 12-day intervals.
On the West Antarctic Ice Sheet (on the left of the image), the Pine Island Glacier is clearly visible below the Antarctic Peninsula. Over the period of the study, the velocity of ice flow at the glacier's grounding line—the point where grounded ice detaches from the bedrock underneath it and becomes a floating ice shelf—increased continuously from approximately 10.6 m per day to 12.7 m per day. Other nearby glaciers also showed increased ice flow. These changes are caused by a range of factors including ocean-induced thinning of the floating ice shelves combined with a retreat of the grounding line. — Ice flow velocity on the Antarctic ice sheet, 2014–2024.

The study shows the rapid flow of ice, moving at average speeds of up to 15 m per day, from glaciers and ice sheets at points around the Greenland Ice Sheet (see image below). Half-way up the western coast of Greenland, Sermeq Kujalleq, also known as the Jakobshavn Glacier, is one of the fastest outlet glaciers in the world with velocities reaching, at times, as much as 50 m per day.
The North-East Greenland Ice Stream (NEGIS), is also clearly visible on the Greenland Ice Sheet and begins far inland at the "ice divide," shown as a dark blue band of nearly stagnant ice in Greenland's interior.

The dataset offers unprecedented spatial detail, with resolution up to 200–250 m, as well as timeframes for tracking movement ranging from less than a week to more than a decade. — Ice velocity on Greenland ice sheet, 2014–2024.

"Exploring Legal Tools for Glacier Protection: Who Speaks for #Glaciers?"

> What #rights do glaciers worldwide—or any natural phenomena, for that matter—have?

#Rights of nature are not just a theoretical concept. Some countries have adopted rigorous rights of nature doctrines—Ecuador was the first to do so, in 2008. Elsewhere, particular elements of nature have been granted legal personhood. But while glaciers have run for president and been mourned at funerals, the only glaciers ever to have been granted legal personhood are the #Gangotri and #Yamunotri glaciers in India in 2017.

Study co-led by ICN2 reveals that #ice is a #flexoelectric material meaning it can produce #electricity when unevenly deformed. Published in Nature Physics, this discovery could have major technological implications while also shedding light on natural phenomena such as #lightning. Frozen water is one of the most abundant substances on #Earth. It is found in #glaciers, on #mountain peaks and in #polar ice caps. https://phys.org/news/2025-09-scientists-ice-generates-electricity-bent.html
