WebJul 7, 2024 · Does thawing permafrost release methane? When permafrost thaws, microbes are able to break down its organic matter. In moist, aerated, soil, this organic matter is mostly converted to carbon dioxide. In wet, low-oxygen conditions, it’s instead converted into methane, which warms the planet 86 times as much as carbon dioxide across 20 years.
