Abstract:Satellite remote sensing is an important tool for continuous monitoring of sea ice covered ocean regions and spatial and temporal variations of their geophysical characteristics [...]
“…In disaster risk reduction, monitoring rapid changes in the cryosphere should be prioritized. For example, high-resolution satellite imagery, aperture radar (InSAR), and ship observations are currently widely used to monitor the distribution and changes of sea ice and icebergs (Leinss et al 2017;Dierking et al 2020). At the same time, it is necessary to strengthen the publicity and popularization of basic knowledge of disaster prevention and mitigation, and enhance their awareness of disaster prevention and mitigation and self-protection (Bajet et al 2008;Tormey 2010) (Fig.…”
Since the 1970s, the ongoing retreat of the global cryosphere has been affecting human societies and causing a series of snow-and ice-related disasters (SIRDs). Based on existing research results, this paper focuses on searching for the formation mechanism of SIRDs, classifies their types and spatiotemporal scales, and reveals the integrated impacts of the SIRD and its future situation on global high-hazard areas. On land, SIRDs mainly occur in the high mountainous areas of middle-low latitude and the permafrost regions of high latitude, in the behaviors of increasing frequency of glacier/snow/glacier lake outburst flood-related disasters and an expanding range of freeze-thaw disasters. The recorded frost events show a decreasing trend but the hail hazard distributions are greatly heterogenous. Overall, the frequency of rain-on-snow events is projected to increase on land in the future. In the ocean, SIRDs are mainly distributed in the Arctic coastal areas and global low-lying islands or areas, with great potential risk. Among them, coastal freeze-thaw, icebergs, and sea-level rise and its impacts are likely or expected to continue increasing in the next few decades.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
