Which risk increases for Arctic infrastructure during seasonal thaw?

💡 Explanation

Infrastructure destabilization risks increase because seasonal thaw triggers solifluction, the gradual downhill creep of saturated soil due to freeze-thaw action. Therefore, ground supports weaken, rather than methane formation, which requires specific pressure conditions.
