Happy to share our new paper in L&O about autotrophic biofilms in subarctic lakes and streams 🦠 🏔️ @aslo.org aslopubs.onlinelibrary.wiley.com/doi/full/10....

Environmental controls of autotrophic biofilm biomass and community composition in subarctic lakes and streams in Greenland

Photosynthetic biofilms are key components of Arctic freshwater ecosystems, supporting primary production and forming the base of aquatic food webs. While several environmental factors regulating bio...

Did you know tiny algae can "skate" within Arctic sea ice? ⛸️ Our new study in @pnas.org reveals the secret life of ice diatoms: they are actively gliding to navigate the ice! This adds a new dimension to the sea ice ecosystem, revealing an active, dynamic ecological niche. @prakashlab.bsky.social

Publication alert 🚨 doi.org/10.1111/mec.... Our new study in Molecular Ecology shows dwarf birch genetic diversity has been shaped by shifting ice sheets and climate transitions over the last 2.6 million years. This history may hold clues to how tundra shrubs face today’s rapid climate change ❄️🌱🧬🌡️

Results show that catchment greenness, nutrients & temperature shape primary producers, but lakes and streams respond to distinct drivers. @fblucph.bsky.social

Mer de Glace, Chamonix, earlier this week. The sad tarpaulin over the visitor glacier grotto shows how desperate it is to save this glacier. It also shows how hopeless it is. The only way to save the glaciers is to urgently cut carbon emissions.

People entering the glacier grotto at Mer de Glace in chamonix. The white tarp on the glacier js tiny in comparison with the largest glacier in France.

Melting over 80.6% of the area of the Greenland Ice Sheet. This is the highest value in our data set, which starts in 1981.

@polarportal.bsky.social

Screenshot from polarportal.dk, a website that makes research on the Arctic research conducted by Danish institutions available to the public and researchers. The image shows Greenland in tan and the Greenland Ice Sheet in red and white. The red part indicates melting and covers all except about 20% in the northeast, which is roughly the area higher than 2500 m above Se level.

Below the map is a chart that compares 2025 melting to the 1981-2010 average. The average melting peaks in mid-July at about 35%. For the last few days, melting has occurred over roughly 80% of the area of Greenland, with a maximum melt area of 80.6% on 24 July 2025. This is the highest value in our dataset, which starts in 1981.
