Which consequence results when thermokarst thawing weakens Arctic slopes?

💡 Explanation

Increased slope mass wasting arises due to thermokarst degradation. The thawing of ice-rich permafrost causes gravitational instability, because the ground loses sheer strength. Therefore, slope failure occurs, rather than sequestering carbon, which could occur theoretically but not with the described mechanism.
