Which outcome occurs when permafrost thaw increases methane seeps near thermokarst lakes?

💡 Explanation

Increased permafrost thaw causes more methane to be released via ebullition; because the warming accelerates decomposition, the greenhouse gas flux will increase. This enhances the initial warming signal, rather than changes in salinity or weathering, which have slower timescales.
