The Swiss village of Kandersteg faces a potential landslide threat from the unstable Spitze Stei rock formation due to thawing permafrost and climate change, prompting extensive monitoring and disaster preparedness measures.
A study published in Science warns that permafrost thaw and wildfires in Siberia could offset 20 percent of required global methane reductions by 2050, potentially undermining international climate goals.
Face aux éboulements menaçant les voies d'ascension du mont Blanc, les refuges de Tête-Rousse et du Goûter ont été fermés ce mardi. Trente-deux alpinistes en autonomie ont dû être h.
Il cambiamento climatico sta scongelando il permafrost in Siberia, rischiando di liberare 'virus zombie' preistorici ibernati. Gli esperti avvertono che la possibilità di infezione esiste, ma la probabilità è ancora incerta.
A study by the Alfred Wegener Institute and MARUM reveals that most ancient carbon released from thawing Arctic permafrost is buried in seafloor sediments rather than converted into greenhouse gases, as microorganisms preferentially consume fresher marine organic matter.
Russia's Vostokgosplan has created a comprehensive plan to adapt Arctic Zone infrastructure to permafrost degradation. The plan includes 20 measures, a monitoring system, and pilot projects, aiming to ensure infrastructure stability and resident comfort.
Mongolia's permafrost is rapidly thawing due to climate change, impacting local ecosystems, herder livelihoods, and releasing greenhouse gases. This transformation offers crucial insights into global permafrost dynamics and future Arctic conditions.
Une équipe canadienne a réussi à extraire de l'ADN mitochondrial ancien de crottes d'écureuil datant de 700 000 ans, trouvées dans le permafrost du Yukon. Ces découvertes, initialement jugées improbables, ouvrent de nouvelles perspectives en paléogénétique.
Alaska's rivers are turning rust-orange as thawing permafrost releases iron and sulfuric acid. A study links this to climate warming, which exposes pyrite-rich rocks and alters wetland chemistry, impacting fish habitats and food webs.
