#NorthwestTerritories #canada The researchers found that instead of a top-down melting process by which the permafrost thawed to a muddy slurry from above, the slides were instead caused by a combination of fire-related thaw & warming temperatures, leading to cracks near the top of the slopes. These cracks allowed the thaw to penetrate deeper, eventually melting the bottom of the permafrost layer https://www.livescience.com/planet-earth/climate-change/a-potential-glimpse-into-the-future-climate-change-has-triggered-permafrost-landslides-with-house-size-blocks-of-ice-in-canada #ClimateChange #UpheavalClimate #pollution #ecology #environment #climate
