Long-buried layers of saline permafrost seem to be accelerating climate change’s transformation of the Arctic. https://scim.ag/46AxH2E

Our new study led by Carl Stadie is using #deeplearning U-Net methods to train on aerial imagery and then analyzed ~32,000 high-res #PlanetScope images across 1.3 million sqkm of the North American Arctic #coastline, mapping close to 20,000 #driftwood deposits. @awi.de www.nature.com/articles/s41...

A new PNAS study links #permafrost thaw and water toxicity levels from metal concentrations. This is bad news for Arctic rivers, their ecosystems, and food chains: www.pnas.org/doi/full/10..... Salmon River in NW Alaska, once praised for its pristine waters, has turned toxic to aquatic life.

New @awi.de study by Inauen et al developed a machine learning method to map landscape-scale #permafrost thaw such as baydzherakh development and thermo-erosion gully change in North Siberia with panchromatic historical Hexagon spy imagery and modern panchromatic sat imagery. doi.org/10.1029/2024...

The NSF-funded Arctic Research Consortium of the United States (ARCUS) will shut down at the end of Sept. ARCUS has been around since the late 80s; in recent years their staff had dwindled, and NSF said earlier this year that their grant would not be renewed. Another blow to polar science.

Study by researchers at the University of Gothenburg shows that almost half of the rising carbon dioxide emissions after the ice age may have come from thawing permafrost. phys.org/news/2025-08...

New study where McKenzie Kuhn, I and co-authors show that accounting for differences among wetland and lake types is crucial for estimating current and future boreal-Arctic methane emissions – out now in Nature Climate Change. www.nature.com/articles/s41...

Witnessing the rapid and extensive thawing of permafrost in Svalbard is truly impressive but deeply concerning

A very successful Perma-X campaign is ending now and both the Polar-5 and the team left Inuvik. We are looking forward to analyze a mountain of >30 TB of new data collected to better understand how fast #permafrost thaws and subsides, coasts erode, and lakes and vegetation change. @awi.de

The vastness of the Mackenzie Delta is impressive. A beautiful landscape formed by one of the largest Arctic rivers, affected by #permafrost, shifting delta channels, lakes, ice, and a harsh Arctic climate right at the land-ocean interface. An ecosystem ranging from tundra to boreal forest.

Now surveying thawing #permafrost landscapes of the Mackenzie Delta region, home of the #Inuvialuit and #Gwich’in people, during the Perma-X 2025 airborne campaign based out of #Inuvik in #Canada. Our platform #AWI Polar-5 is a refitted DC-3 BT67 equipped with high res cameras and lidar sensors.

Great to see our work in @eos.org ! A good read for the evening! 😇 kudos to all our friends & colleagues that contribute to this ongoing endeavour - there is so much to learn! 🤩 together - always! @thomasopel.bsky.social @juvmcburst.bsky.social @pucicu.de @scitobias.bsky.social @leverhulme.ac.uk

“It's our job to learn, then empower and allow [communities] to create things important to them, prioritize projects important to them, and provide tools and resources.” Great conversation with our collaborator Jackie Qataliña Schaeffer about adaptation planning and Indigenous infrastructure.

Concluded our West Alaska #permafrost studies for 2025. Had a great time in #Kotzebue with a strong AWI-UAF team, fantastic local partners, and mostly nice weather for boating, ATV travel, and tundra hiking. Studied lake drainage, hydrochemistry, erosion, subsidence, vegetation, & paleo-permafrost.

The term “abrupt permafrost thaw” is increasingly used in the scientific literature. The concept comes with challenges as authors look at “abrupt“ change with different perspectives on time scales, magnitudes, and impacts. Webb et al developed a new conceptual framework: doi.org/10.1007/s406...

First week of #permafrost work in #Kotzebue on the Baldwin Peninsula is completed with surveys and sampling of the impressive Cape Blossom, a large hillslope drainage gully east of Kotzebue, and the drained thermokarst lake basin at the Schaeffer family home. Several more days to come…

On our way to #Alaska 🛫💫 for fieldwork around Kotzebue on the Baldwin Peninsula 🇺🇸, a region strongly affected by permafrost thaw as seen in the ALEX portal alex.awi.de. At the same time, our Perma-X #permafrost airborne campaign with #AWI Polar-5 will start in #Inuvik in Northwestern Canada 🇨🇦 🍁

We continued our studies on what happens biogeochemically (carbon, nitrogen, lipid biomarkers, mercury), when terrestrial #permafrost transitions from land to aquatic environments such as thermokarst lakes and lagoons with an example from the #Alaska North Slope: doi.org/10.5194/bg-2...

Detailed investigations of permafrost deposits in Arctic Siberia suggest a much warmer Last Interglacial than today for that region: new Study out by Schirrmeister and a larger international team of colleagues: doi.org/10.5194/cp-2...

I have a fully funded PhD position open for start in Jan or May 2026. Field work in peatlands of the Northwest Territories, with lab work to understand potential downstream mobilization of carbon, nutrients, mercury after thaw or wildfire. Reach out for more information, and please send on!

Woah, rare to see this kind of language in Nature 👀 “We show that +1.5 °C is far too high and that current climate conditions…could trigger rapid ice sheet retreat and high rates of Sea Level Rise... that would stretch the limits of adaptation” and could have “catastrophic consequences for humanity”

Our Arctic Landscape EXplorer (ALEX) tool nicely shows one of the largest retrogressive thaw slumps on Earth - this impressive rapid #permafrost thaw feature is located on Banks Island: alex.awi.de?lat=73.07764...

Excited to be the Mountainfilm 2025 mural artist in Telluride! My mural, "Cartographies of Arctic Change" (a massive 26.5' x 36'!), visualizes our Arctic research. It's going up now on Telco Coffee, a wall previously graced by JR, Gregg Deal, Banksy, and more. Come see it in Telluride!

We have a postdoc position open for TDX SAR data processing within the 3D-ABC Foundation Model project aiming at quantifying global terrestrial carbon stocks.

What happens in the Arctic doesn't stay in the Arctic. It affects us all. The Arctic Monitoring and Assessment Programme (AMAP) has released their Summary Arctic Climate Change Update. Read it: www.amap.no/documents/do... Nobody can later say they weren't warned, again and again.

Permafrost thaw is expected to impose costs of $37 billion to $51 billion to Alaska roads and buildings through the middle of the century, according to a newly published study. via @alaskabeacon.com

Effective immediately, the PGC is no longer accepting new NSF-supported requests due to a lack of renewal funding. Current work is wrapping up. Please contact your NSF program officer if impacted. We’re grateful to have supported your polar research. Read our full statement at www.pgc.umn.edu

Climate warming in the Arctic means #permafrost is not permanent anymore. In 2022, we published a study estimating risks from industrial legacy sites with contaminants across the Arctic: doi.org/10.1038/s414.... The #wjs now reports on an arsenic-contaminated site impacted by thaw near Yellowknife

FYI: The Spencer Foundation, Kapor Foundation, The William T. Grant Foundation, and the Alfred P. Sloan Foundation have collaborated to offer $25K rapid response grants. "This rapid response bridge funding opportunity is for scholars and teams whose grants have recently been cancelled by NSF."

Maren Jenrich et al published our new study on how thermokarst lagoon formation impacts carbon cycling along gradients of increasing marine influence, which is very relevant for Arctic permafrost coasts affected by coastal erosion and sea level rise #permafrost, #lagoons, doi.org/10.5194/bg-2...

Deep in the Arctic Ocean, the seabed is frozen, but now that the #permafrost is thawing, large quantities of methane gas may rise to the surface. Birgit Wild wants to find models to predict what this means for the #climate #research #science @stockholm-uni.bsky.social tinyurl.com/3xstbj8c

New paper 📝 After 4 years of work and 870 GB of modelling, remote-sensing, and observational data, I’m delighted to share our work on permafrost modelling ❄️ We focused on snow insulation, one of the key drivers of permafrost dynamics

The #ERC-funded Q-Arctic project is now on Bluesky! Q-Arctic explores consequences of global change in #Arctic regions. The challenge is to reconcile the process, satellite observation and model simulation scales, given the heterogeneity of Arctic landscapes. Learn more about Q-Arctic: q-arctic.net

Nice video summary of the more than 10 years of the #Permafrost Carbon Network (PCN), an international researcher network, and some important insights of why permafrost carbon matters in the climate system.

Retrogressive thaw slumps form due to rapid thaw of ice-rich #permafrost. While increases in thaw slump numbers & areas have been found in NW Canada before, we now show that also the Russian High Arctic is impacted by accelerating thaw slump formation: agupubs.onlinelibrary.wiley.com/doi/full/10....
