Risk assessment of infrastructure destabilization due to global warming in high mountain in the French Alps.
International audience Due to ongoing global warming, high alpine environments are affected by significant changes, such as glacial retreat and permafrost warming, which can trigger mass movements in rock slopes or superficial deposits. These processes generate a risk of direct destabilisation for h...
