“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…”

#Erosion, #Erdrutsche und die Freisetzung von #Schadstoffen bedrohen #Infrastruktur, Wasser- und #Nahrungsversorgung.
Auch #Krankheitserreger aus dem gefrorenen Boden könnten gesundheitliche Risiken bergen. Diese Entwicklungen sind keine #Zukunftsprobleme, sondern bereits Realität.

Permafrost Thaw 🧊🔬
The thawing of #permafrost is associated with the release of several significant components, including:
• Ancient #microorganisms that may harbour #antimicrobial resistance (AMR) genes
• Accumulated pollutants and #HeavyMetals
• #Methane, which plays a role in accelerating #ClimateChange
• Newly created #ecological niches that may support #pathogens

Der Klimawandel lässt den Permafrost schmelzen und fördert »zeitreisende« Mikroben zutage. Was passiert, wenn solche längst vergessenen Organismen auf die moderne Welt treffen?#Klimawandel #Krankheitserreger #Pathogene #Bakterien #Viren #Immunsystem #Simulation #Modellierung #Evolution #Permafrost #ErdeUmwelt #Biologie
Uralte Pathogene aus dem Permafrost sind reale Gefahr -
Der #Methangehalt der #Atmosphäre steigt seit einigen Jahren dramatisch und mehr als erwartet. #Wissenschaftler suchen daher mit Hochdruck nach den Ursachen.
Eine davon: Tropische #Feuchtgebiete geben bis zu 1,4 Millionen Tonnen mehr #Methan pro Jahr ab.

Sie speichern CO2, aber emittieren Methan. Feuchtgebiete spielen eine wichtige Rolle beim Klimaschutz. Doch die steigenden Temperaturen verstärken den Effekt.#Methan #Kohlenstoff #Feuchtgebiet #Tropen #Sumpf #Moor #Regenwald #Treibhausgase #Klimawandel #Umweltschutz #Permafrost #ErdeUmwelt
Feuchtgebiete setzen verstärkt Methan frei -
Versteckt im Permafrost: Studie nimmt 13 vergessene #Viren unter die Lupe (futurezone)
Im #Permafrost gefangene #Krankheitserreger sind nicht zwingend tot. Forschende haben sie im Labor reaktiviert. Frühere Untersuchungen hätten fälschlicherweise nahegelegt, „dass ‚Zombie-Viren‘ keine Bedrohung für die öffentliche Gesundheit darstellen“
