🐿️ 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.

[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/

Ein KI-Modell des #AWI soll helfen, den globalen #Kohlenstoffkreislauf besser zu verstehen – von den tropischen #Regenwälder​n bis zum tauenden #Permafrost.

Komplexe Rückkopplungen im #Erdsystem sollen besser erfasst und fundiertere Prognosen ermöglicht werden. Mit großen Datenmengen, etwa der #Erdfernerkundung und Biomasse-Infos, wird das Modell trainiert.

Das rasante Abschmelzen von #Gletschern gefährdet laut #UN die #Nahrungsversorgung und #Wasserversorgung von bis zu 2 Milliarden Menschen weltweit.

Besonders betroffen sind #Gebirgsregionen, deren #Landwirtschaft stark von #Schneeschmelze und #Gletscherwasser abhängt.

Die #Erderwärmung führt zu #Dürren, #Überflutungen und dem tauen von #Permafrost.

#Erosion, #Erdrutsche und die Freisetzung von #Schadstoffe​n bedrohen #Infrastruktur, Wasser- und #Nahrungsversorgung.

Auch #Krankheitserreger aus dem gefrorenen Boden könnten gesundheitliche Risiken bergen. Diese Entwicklungen sind keine #Zukunftsprobleme, sondern bereits Realität.

"Kryosphären-Bericht: Deutlich weniger Schnee und Eis in Österreich"
https://science.orf.at/stories/3222889/

"Die aus den Messungen belegten markanten Veränderungen der Kryosphäre würden die enorme Temperaturzunahme in den Alpen seit ca. 1980 widerspiegeln."

"Die seit den 1880er-Jahren um rund zwei Grad Celsius gestiegene mittlere Jahrestemperatur in Österreich führe zum Auftauen des Permafrosts. Dessen zuvor stabilisierende Wirkung auf Grate, Schutthalden oder Felswände lasse bereits bei Erwärmung deutlich nach „und ist aktuell nur mehr deutlich reduziert gegeben“, heißt es in dem Bericht."

"Das fehlende Eis [auf Seen] hat nicht nur Auswirkungen auf den Tourismus, sondern auch auf wichtige Ökosystemprozesse in Seen."

"Geplant ist künftig eine jährliche Erscheinungsweise der Analyse, die heuer vom Klimaministerium gefördert wurde. Allerdings fehle ein Förderinstrument für ein regelmäßiges Kryosphären-Monitoring in Österreich, heißt es in dem Bericht." #IWüsGorNetWissenNetSoGenau
