The Breakdown of Natural Systems Could Intensify Warming by 30 Percent

A modeling study finds that emissions from deteriorating natural systems could amplify human-driven warming by 20 to 30 percent. These feedbacks remain largely absent from influential climate models and could add warming even if humans reach net zero.

一项建模研究发现，自然系统退化产生的排放可能使人类活动造成的变暖加剧20%至30%。这些反馈效应在重要气候模型中仍基本未被纳入，即使人类实现净零排放，也可能带来额外升温。
