Landslides, avalanches and other hazards:
Landslides, avalanches, and other hazards: In the age of global warming the occurrence of many types of geological mass movements is tied to degrading ice and permafrost. Many large submarine landslides have developed along layers of weakness tied to frozen methane hydrates, and are thus emblematic of the growing hazards of catastrophic sediment transport and concomitant release of greenhouse gases.
The degradation of alpine and polar permafrost further seems to give rise to spectacular long-runout ice-rock avalanches with a destructive potential rarely witnessed in historic times.
Despite these intuitive links between global warming, dwindling ice resources, and increased slope instability, only the most recent landslide datasets have begun to afford sufficient statistical robustness to start searching for significant increases in mass-movement activity triggered by climate change.
