Climate change in the mountain cryosphere: impacts and responses

Addressing the impacts of climate change in the high-mountain cryosphere and downstream regions, as well as responses to these impacts, has increasingly been the focus of research activities in recent years (e.g. Huss et al. 2017 ; Milner et al. 2017 ; Vuille et al. 2018 ). Studies aim at documenting and enhancing our understanding of processes and drivers related to these impacts, the extent of their negative effects, and the perception of these problems from the perspective of those affected. In parallel, the Intergovernmental Panel on Climate Change (IPCC) has presented an opportunity in its sixth assessment cycle (AR6) to address and respond to knowledge gaps on climate change impacts in the high-mountain cryosphere, further motivating the research activity seen on the topic.
