Here's a closer look at the record low sea ice conditions around #Svalbard. The ice edge is still close to the 85°N line of latitude along the Atlantic front. That's a lot of open water into the Barents Sea region! Data from AMSR2.

Graphic showing Arctic sea-ice concentration on 10/13/2025 near Svalbard, Greenland, and Novaya Zemlya. A line of 85°N latitude is also annotated along with the Atlantic Ocean.

'Eight of Sweden's 277 glaciers melted completely during 2024 and are now extinct due to global warming...

Another 30 glaciers are at risk, glaciology professor Nina Kirchner said.

The extinct glaciers "won't come back in our lifetime and not if global warming continues", she said.'

Now that we know of 12 more sub glacial lake -filling and drainage events in Antarctica, the connection to the ice stream velocities or calving frequency would be very interesting…

Our new paper compares GPR ice thickness data with models and looks at glacier thermal structures in Greenland, showing that thermal complexity (warm-cold ice) inside these glaciers is higher than expected.

2022-2025 ice caps across Edgoya, Svalbard lost all snow cover, resulting all firn cover being lost too. This removes ability of meltwater to refreeze. In 2025 we again see this playing out on the ice caps of Edgeøya. @yogaski.bsky.social @willharcourt.bsky.social glacierchange.blog/2025/09/11/s...

On Svalbard, rain falls where snow once lay.

The white patches of ice and snow slip away, leaving the mountains darker, bare, and heavy with melt.

What once gleamed now fades—a stark reminder of a world warming too quickly.

Annual mass balance survey with AG-315 UNIS students at upper Foxfonna near Longyearbyen. Even after last summer’s record heat, ~1 m of ice was lost at 550–600 masl.

On low‑elevation #Svalbard glaciers, melt overwhelms any chance of accumulation ~ highlighting the sensitivity of the ice to temp

Sad views from southern #Svalbard 30.8.25 - melt has reached high up the mountains. From Hornsund to Amundsenisen barely any snow left… how should glaciers build mass like this? Svalbard is heating fast. Only steep mountain walls seem to help accumulate a bit and catch blown snow 📸from✈️
