🐿️ WATCH: In the #Yukon #permafrost, researchers found 700,000-year-old fossilized #dung from an #extinct ground #squirrel species.

These preserved #burrows contained ancient plant material, #bones, and the oldest #woollymammoth #DNA identified in #NorthAmerica, tracking how #prehistoric #ecosystems shifted over time.

[Science News] Rising global #temperatures are leading, in particular, to the melting of #permafrost . This permanently frozen soil stores a massive amount of organic #carbon (1,300 gigatons across the #arctic ) which rivers carry out to sea. However, a recent analysis of marine sediment cores shows that only 10% of this organic carbon is converted into gas by microorganisms, and thus contributes in turn to #globalwarming : https://scitechdaily.com/thawing-permafrost-is-releasing-carbon-but-something-unexpected-happens/

H/T @abhinav Alangadan
“Can we develop a first-order understanding of permafrost degradation and glacial lakes exposed to degradation-induced mass movements in the Himalaya?
[The authors] tried to address this question. The study [first link above] integrates machine learning, statistical modeling, and numerical modeling to investigate high-resolution permafrost distribution, potential degradation, and associated mass-movement hazards in the Kinnaur district of Himachal Pradesh, India.
Using rock glaciers as proxies, [they] generated a high-resolution permafrost distribution using machine learning, while potential degradation zones were delineated using the 0°C isotherm as a first-order indicator. [They] further identified glacial lakes located near potentially degrading permafrost zones and reconstructed their bathymetry. A detailed scenario-based GLOF process-chain simulation was then carried out for Kashang Lake using r.avaflow and HEC-RAS.
[Their] results indicate that seven glacial lakes in #Kinnaur are located close to potentially degrading permafrost zones. The simulations further show that a potential GLOF from Kashang Lake could inundate critical downstream infrastructure, including nearly 11 km of National Highway 5…”

Die #Klimakrise trifft #Deutschland:

Der #Permafrost an der #Zugspitze wird laut Forschenden voraussichtlich bis 2050 verschwinden.

Auch der #Gletscher Nördlicher #Schneeferner ist stark betroffen. Seine Fläche hat sich seit 1980 mehr als halbiert, seine Dicke drastisch abgenommen.

Die Stabilität des Berges könnte dadurch gefährdet sein. Etwas besser steht es um den #Höllentalferner, der durch #Lawinen und Schattenlagen begünstigt ist.

Der #Klimawandel verstärkt Naturgefahren in den #Alpen, wie eine Schweizer Metastudie zeigt.

Besonders #Steinschläge nehmen in Hochlagen zu, da das Tauen von #Permafrost und #Gletscherschwund Gestein destabilisieren.

Auch #Bergstürze und #Murgänge könnten häufiger werden. #Lawinen enthalten zunehmend Nassschnee und treten in höheren Lagen vermehrt auf.
