Precarious is our life on this planet. From the article:

"The warming, combined with other climate effects like extreme rainfall, is speeding up some basic geological processes. Softer rocks and soils that used to stay frozen most of the year, like permafrost, are thawing and eroding faster. Seemingly monolithic slabs of solid granite are peeling off mountainsides like the layers of an onion. And powerful rock glaciers—wide swaths of slow-moving ice and rock rubble that can pulverize granite—are speeding up, in one case from 40 feet per year to 226 feet per year.

"Continued warming and the thawing of permafrost also increases the chances for big mudslides and debris flows. As more and more of the previously frozen soil thaws, it can easily be set into motion by rain, said climate scientist Ketil Isaksen of the Norwegian Meteorological Institute.

"Along with the melting permafrost, another force is at work. Steep rock walls that were once buttressed by glacial ice several hundred feet thick have been laid bare as the glaciers receded. With nothing to hold them back, gravity pulls the rock toward the valley floors."
