Which outcome occurs when thawing Siberian permafrost collapses?

💡 Explanation

Accelerated warming develops because thawing creates thermokarst wetlands, accelerating decomposition and causing methane ebullition. Methane, rather than CO2 is released due to anaerobic conditions; therefore warming trends are accelerated, rather than balanced via sequestration.
