Microbial photosynthesis mitigates carbon loss from northern peatlands under warming

Nature Climate Change, Published online: 20 March 2025; doi:10.1038/s41558-025-02271-8

The authors use experimental and modelling approaches to understand the response of microbial photosynthesis to peatland warming. They show that warming amplifies microbial photosynthesis, which could offset rising CO2 emissions from northern peatlands by 6.0–13.7% in 2100 (SSP 2-4.5–SSP 5-8.5).
