Glacier and permafrost risks in a changing climate

The cryosphere is a key component of high mountain systems, controlling their dynamics. Climate change is causing unprecedented changes in the cryosphere, with severe consequences on natural instability. Glacier and permafrost hazards, which are the focus of the IACS/IPA Standing Group GAPHAZ, existed in the past, but are currently changing in size, frequency, type and location in response to ongoing climate change, sometimes producing catastrophic process chains. This session invites contributions aimed at enhancing our understanding of such hazards, including glacial lake outburst floods, ice and rock avalanches from steep glaciers and frozen slopes, glacier surges, destabilization of rock glaciers and other periglacial slope movements, and the interactions with earthquakes and volcanic activity. We welcome contributions that consider past, present and future hazards, as well as all components of risk. Contributions that provide insights into recent events, hazard and risk assessment, monitoring and modeling, and approaches to manage disaster risks in high mountain regions, are encouraged.
