Which risk escalates when increased Arctic air temperatures degrade permafrost layers under a sloped landscape?

💡 Explanation

When permafrost thaws on slopes, weakened soil shear strength enables solifluction, because gravity induces soil creep into distinctive lobes. Therefore solifluction lobe movement accelerates displacing infrastructure, rather than methane formation or increased sequestration, mechanisms needing very specific subsurface marine or soil conditions, respectively.
