#Permafrost ist ein wichtiges Puzzleteil im Ökosystem der #Arktis: Er speichert Kohlenstoff über lange Zeiträume und bietet festen, stabilen Grund. Schmilzt das Eis, entstehen sogenannte Thermokarstseen.
AWI-Forschende haben nun die Datenbank "Lost Lakes" aufgebaut, die wichtige Informationen über den Zustand von Thermokarstseen der Arktis bereitstellt. Das ermöglicht es, Veränderungen in den Permafrostlandschaften zu erkennen, sobald sie passieren.

“Permafrost soils are particularly vulnerable to climate change. To assess and improve estimations of carbon (C) and nitrogen (N) budgets it is necessary to accurately map soil carbon and nitrogen in the permafrost region. In particular, soil organic carbon (SOC) stocks have been predicted and mapped by many studies from local to pan-Arctic scales. Several studies have been carried out at the Canadian Beaufort Sea coast, though no regional maps of terrestrial carbon stocks based on spatial modelling has been conducted yet. This study combines available field data from the Canadian Yukon coastal plain and uses it to map regional SOC and N stocks using the machine learning algorithm random forest and environmental variables based on remote sensing data. [The authors] developed models using the data for the entire region and separate models for the coastal mainland area and Qikiqtaruk Herschel Island. Each model was used to map SOC and N stocks for its respective area. [They] assessed the performance of the different random forest models by using crossvalidation. [They] further assessed model results using the Area of Applicability (AOA) method and the quantile regression forest approach, comparing the results and discussing their implications within the context of both methods. [They] explore[d] local differences in soil properties and how soil data distribution across the region affects the accuracy of the predictions of SOC and N stocks..."

“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…”

Okay, dann ist die nächste #Pandemie wohl von einer #Bakterie:
Ein 5.000 Jahre eingefrorenes #Bakterium aus einer rumänischen #Eishöhle zeigt Resistenz gegenüber zehn #Antibiotika.
Forschende fanden mehr als 100 #Resistenzgene, die beim Auftauen in die Umwelt gelangen und heutige Erreger stärken könnten.

Risiko für irdische „Heißzeit steigt
Klimaforscher warnen: Destabilisierung des Klimasystems wird wahrscheinlicher#Klimaforscher warnen: Das #Erdklima könnte dem Übergang zu einer neuen #Heißzeit näher sein als gedacht. Denn durch die zunehmende #Erwärmung und steigenden #Treibhausgas'werte hat sich das Risiko für ein Umkippen mehrerer Stellschrauben im #Klimasystem weiter erhöht. Positive #Rückkopplungen und #Fernwirkungen über Kontinente hinweg könnten dann einen #Kaskadeneffekt auslösen, der das Erdklima destabilisiert. Dann könnte die Erde in einen neuen Zustand geraten, der nach menschlichen Zeitmaßstäben irreversibel ist – eine Heißzeit.
Einige der Klima-Stellschrauben könnten schon jetzt in ein neues Gleichgewicht gekippt sein. „Dies ist der Fall bei den Eisschilden #Grönland's und der #Westantarktis, für den borealen #Permafrost und die #Berggletscher“, berichten die Forscher. Auch der #Amazonas-#Regenwald stehe kurz vor dem Umkippen.

Eilisessä Kokkolan Talviharmonikan konsertissa kantaesitettiin Cecilia Damströmin haitarikonsertto Permafrost, ikirouta, https://areena.yle.fi/podcastit/1-67590395
Ihan kiva kuunneltuna. Oli kuulimma kuvaakin mukana, ja sitten tietysti selitystä (etenkin perästäpäin). Solistina toimi Sonja Vertainen, ja Keski-Pohjanmaan kammariorkesteria johti Jan Söderblom.
Tuo kappale alkaa 25 minuutin ja päättyy 44:n kieppeillä.
