Description:
Bertin et al (2025) focuses on carbon and nutrient cycling in terrestrial ecosystems under changing climate conditions. It examines how warming and altered precipitation patterns affect soil organic matter decomposition, greenhouse gas emissions (CO₂, CH₄, N₂O), and nutrient availability. The study uses field experiments and modeling approaches to predict long-term impacts on ecosystem productivity and carbon sequestration. Key findings suggest that climate-driven changes in microbial activity and plant-soil interactions could accelerate carbon loss from soils, potentially reducing their role as carbon sinks.
