"The soil carbon feedback concerns the releases of carbon from soils in response to global warming. This response under climate change is a positive climate feedback. There is approximately two to three times more carbon in global soils than the Earth's atmosphere,[1][2] which makes understanding this feedback crucial to understand future climate change. An increased rate of soil respiration is the main cause of this feedback, where measurements imply that 4 °C of warming increases annual soil respiration by up to 37%.[3]"[1]

Uncertainties

Many climate models to not account for feedback loops relating to carbon released from soil triggered by increased temperatures.[2] A limitation in our understanding of carbon cycling comes from the insufficient incorporation of soil animals, including insects and worms, and their interactions with microbial communities into global decomposition models.[3][4]
