🐿️ ICYMI: 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.

“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…”

Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point
The results revealed a clear and troubling pattern across all warming levels. Even under low to moderate warming, #carbon losses through respiration outpaced photosynthetic carbon gains by 1–16-fold.
Warming by +1°C, +2°C, and +4°C increased annual net #CO2 release by 44%, 80%, and 176%, respectively, and the site was a net carbon source before any experimental warming began.
"When warming reaches around 2–4°C, the system changes fundamentally," Ding told Phys.org. "Plants begin to reach their thermal and water-stress limits, so photosynthesis declines. At the same time, thaw penetrates deeper into the #soil, exposing old #permafrost carbon that has been frozen and protected for hundreds to thousands of years. Once thawed, microbes can decompose it and release it as CO2."
