Which hazard is amplified when rising global temperatures causes thermokarst development in artic regions?

💡 Explanation

When temperatures rise, thermokarst processes accelerate because permafrost thaws, destabilizing methane hydrates trapped within the frozen ground and sediments, leading to methane release. Elevated methane emissions occur, rather than increased reflection, reduced discharge, or iron oxidation, which are unrelated or have opposing drivers.
