Which effect occurs given that the summer active layer thickness exceeds design assumptions in discontinuous permafrost?

💡 Explanation

Increased active layer thickness causes more ground ice to thaw, triggering thermokarst formation via the mechanism of thaw settlement; therefore, subsidence occurs, rather than reduced heave, driven by consolidation not rebound changes, or methane effects.
