The relation to the #permafrost melting, as suggested in the paper, is questionable because of low elevation of the event…
But any impact from the heavy rains of past days?

Ecroulement rocheux hier en vallée de #maurienne entraînant la coupure des voies de communication vers l’Italie.
La relation avec la fonte du #permafrost, comme suggéré dans l’article ci-dessous, me paraît assez douteuse compte tenu de l’altitude de l’événement.
En revanche, une relation avec les précipitations des derniers jours?

Grunnen på de høyeste fjelltoppene har ofte #permafrost. Når denne tiner så blir massen ustabil og kan begynne å flytte på seg veldig raskt. Toppen av Mount Fluchthorn raste i sommer #klima

#ClimateChange:
"First, the #fires in #boreal regions become more intense, and, because of the tremendous heat being generated, #peat, which has stored carbon for thousands of years, can start to burn and contribute massive amounts of carbon to the air.
That carbon will take at least another 1,000 years to go back into the peat.
Second, in boreal regions, fires can thaw #permafrost, beginning a cascade of microbial processes that may also generate #GreenhouseGases"

Warum ist eine Geschichte über den in #Kärnten nahe #Salzburg liegenden #Großglockner im ORF-Tirol?
Antwort an mich selbst: Weil er an der Grenze Tirol/Kärnten liegt.
Man lernt nie aus (glaub, das hab ich in der Schule anders gelernt).

Happy #FossilFriday from the #Alaska State Museum! In the Lower 48, most #mammoth fossils are Columbian #mammoths, but the colder climates of the Last Frontier favored its hairy cousin. These woolly mammoth #tusks were found in the #permafrost around #Fairbanks, but they're common enough across Alaska that they've been named its state #fossil!

A Swiss mountain peak fell apart, sending 3.5 million cubic feet of rock into the valley below. Scientists warn climate change could make more mountains crumble. The collapse was caused by thawing permafrost, a layer of frozen ground that holds the mountain together. #ClimateChange #Permafrost #MountainCollapse https://www.businessinsider.com/mountains-switzerland-collapsing-from-permafrost-melt-2023-8

2475 followers · 8695 posts · Server climatejustice.globalIn der Klimawissenschaft ist ein Kipppunkt definiert als "eine kritische Schwelle, jenseits derer sich ein System neu organisiert, oft abrupt und/oder irreversibel" (Lenton et al., 2008). Hier sind 10 #Kipppunkte, die für uns zunehmend an Bedeutung gewonnen haben.
"Einige der im #IPCC-Bericht erörterten abrupten Klimaänderungen und Kipppunkte könnten schwerwiegende lokale Klimareaktionen nach sich ziehen, wie extreme Temperaturen, Dürren, Waldbrände, Verlust der Eisschilde und Zusammenbruch der thermohalinen Zirkulation.
Es gibt Hinweise auf abrupte Veränderungen in der Erdgeschichte, und einige dieser Ereignisse wurden als Kipppunkte interpretiert (Dakos et al., 2008). Einige davon sind mit bedeutenden Veränderungen des globalen Klimas verbunden, wie z. B. die Interglaziale im Quartär (vor 2,5 Millionen Jahren) und die rasche Erwärmung während des thermischen Maximums im Paläozän und Eozän (vor etwa 55,5 Millionen Jahren; Bowen et al., 2015; Hollis et al., 2019).
Solche Ereignisse veränderten das planetare Klima für zehn- bis hunderttausende von Jahren, aber mit einer Geschwindigkeit, die tatsächlich viel langsamer ist als der projizierte anthropogene Klimawandel in diesem Jahrhundert, selbst wenn es keine Kipppunkte gibt" (IPCC, 2021).

24 followers · 73 posts · Server masto.esEl permafrost es el suelo permanentemente congelado que se encuentra en las regiones más frías del planeta. A pesar de su importancia ambiental como almacén de carbono, el calentamiento global está provocando el derretimiento del permafrost, lo que libera grandes cantidades de gases de efecto invernadero a la atmósfera y contribuye al cambio climático. La protección del permafrost es vital para preservar el equilibrio natural del planeta y mitigar los efectos del calentamiento global. #Permafrost #CambioClimático #MedioAmbiente
