  1. A crise climática já move montanhas

    Degelo e chuvas extremas desestabilizam sistemas geológicos que antes pareciam inabaláveis. Impactos vão além das regiões polares. Uma onda de deslizamentos, degradação do solo, terremotos e danos a infraestruturas pode estar só começando

  2. The world’s vast permafrost regions contain three times more carbon than all living vegetation. Some are thawing and emitting more and more greenhouse gases.

    #Permafrost cannot refreeze back. "Once you pass the permafrost’s threshold and the ice has gone and the landscape has changed, it is not going to come back for hundreds of years. On a human timescale, those systems have then effectively tipped into a system that will keep emitting carbon for decades or centuries."

    "Unfortunately, there are no feasible geoengineering solutions on a broad scale. The only way to limit the thawing of millions of square kilometres is to reduce emissions rapidly. We need to act urgently."

  15. Extreme #Hitze und tauender #Permafrost destabilisieren die französischen Alpen.

    Im Mont-Blanc-Massiv wurden 2026 bereits 450 Felsstürze registriert. Der bisherige Höchstwert von 300 stammt aus 2022. Neben dem Permafrost-Abbau erhöht auch der Gletscher-Rückgang die Gefahr instabiler Felswände.

    Mehrere Menschen kamen in diesem Sommer bereits durch #Felsstürze ums Leben. Behörden rufen #Bergsteiger zu besonderer Vorsicht auf.

    “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..."

    Oberhalb von #Kandersteg könnten sich am Spitze Stei bis zu 20 Millionen Kubikmeter Gestein lösen. Eine unmittelbare Gefahr für das Dorf besteht derzeit nicht.

    Der Berg wird kontinuierlich überwacht, Evakuierungspläne liegen vor. Steigende Temperaturen lassen #Permafrost und #Gletscher tauen und können dadurch Berghänge destabilisieren.
