Nature – Klemme et al. (2022): Destabilization of carbon in tropical peatlands by enhanced weathering

Here, the authors present estimates for the response of CO₂ emissions from tropical peat soils, rivers and coastal waters to changing soil acidity induced by enhanced weathering application. They estimate that the potential carbon uptake associated with enhanced weathering is reduced by 18–60% by land-based re-emission of CO₂ and is potentially offset completely by emissions from coastal waters.
