Which outcome occurs when thawing permafrost destabilizes tundra?

💡 Explanation

Increased methane hydrate release occurs because permafrost thaw promotes microbial decomposition of formerly frozen organic matter via methanogenesis. This releases stored methane, rather than enhanced carbon uptake by vegetation; therefore permafrost thaw amplifies global warming.
