Which risk increases when warming temperatures degrade permafrost beneath Arctic infrastructure supports?

💡 Explanation

When permafrost thaws, soil loses its structural integrity because the ice within the soil melts, causing subsidence. Therefore structural failure due to soil subsidence risk increases, rather than methane release, albedo increase or dormant pathogen release, which depend on other mechanisms and compositions of the permafrost.
