Statements
Permafrost, ground frozen below 0°C for at least two years, gradually melts due to heat, a process known as permafrost thaw. This can span decades to centuries, impacting ground stability, infrastructure, and releasing greenhouse gases. Thawing moderates temperature changes through the ice-water phase transition. Once thawed, the ground no longer qualifies as permafrost.
