Sensationalized soil carbon sequestration estimates excuse further climate inaction.

The article discusses the claims made by Almaraz et al. regarding the potential of soil carbon sequestration (SCS) to meet the goals of the Paris Agreement. The authors argue that the estimates provided by Almaraz et al. are based on flawed assumptions and could undermine efforts to reduce greenhouse gas emissions. They highlight concerns about the availability of feedstock for SCS practices, the loss of carbon during composting and biochar production, and the questionable assumption of additive effects. The authors also point out the geographical and climate bias in empirical estimates of SCS potential and the need to consider nitrogen emissions and methane production in agricultural systems. While acknowledging the urgency of climate action, the authors caution against relying on SCS as a substitute for immediate emissions reductions. [Extracted from the article]
