永久冻土融化:模型低估了气候的重大盲点 · 跟踪 1 个来源

永久冻土是覆盖北半球约 15% 土地的冰冻土壤层,其含碳量是大气中的两倍。随着全球气温升高,这一层土壤开始融化,微生物得以释放出二氧化碳和甲烷等强效温室气体,形成加速变暖的反馈循环。包括联合国在内的当前气候模型,在很大程度上低估了永久冻土融化的影响,特别是像野火这样的事件造成的突然融化。由于气候变化,野火变得越来越强烈,这会显著加速永久冻土的退化,可能释放出大量储存的碳。 AI

    Three things you should know about permafrost

    How much do you know about permafrost? Maybe, like me, you’ve been aware that this layer of frozen soil is thawing, that it’s important in the global puzzle of climate change … and that’s about the extent of it.&#160;&#160; The great news for both of us is that my colleague James…
