Which outcome results when Alaskan permafrost degradation accelerates?

💡 Explanation

Increased permafrost thaw leads to methane release and thermokarst development because destabilized organic matter decomposes via microbial action; this accelerates the positive feedback mechanisms. Therefore “methane release” rather than “river sediment discharge” is seen because hydrology is less central to accelerating thaw.
