Mudslides and climate change. Does the recent tragedy in Washington state portend to much such devastating mudslides in a changing climate?

The Relationship Between Landslides and Climate Change in North America

While the causal factors involved in landslides are complex, there is a strong body of research which supports the idea that climate change will increase the number of slides. The key factor connecting climate change to landslides is water. This linkage has been evinced in both geological and hydrological research. As University of Washington geologist Dave Montgomery explained in an…
