Which outcome results from thermokarst development in tundra?

💡 Explanation

Accelerated coastal erosion occurs because the thawing permafrost due to climate change causes widespread ground subsidence (thermokarst). This exposes previously frozen coasts to increased wave action leading to more rapid erosion, rather than stabilization or enhanced water retention which would imply colder conditions.
