Evidence supports the concept of a positive feedback loop linking climate change and phosphorus cycling, primarily mediated through coupled soil carbon-phosphorus stoichiometry and greenhouse gas emissions.
The provided literature includes direct evidence of phosphorus playing a role in climate change feedbacks, such as soil phosphorus influencing greenhouse gas production and being tightly coupled with soil carbon cycling (Papers [3] and [11]). The remaining papers primarily focus on carbon-climate feedbacks without addressing phosphorus. Thus, the specific claim is supported by the relevant subset of retrieved literature.
