Nature – Yuan et al. (2024): Weakening of global terrestrial carbon sequestration capacity under increasing intensity of warm extreme

Xiuliang Yuan, Xi Chen, Friday Uchenna Ochege, Rafiq Hamdi, Hossein Tabari, Baofu Li, Bin He, Chi Zhang, Philippe De Maeyer, Geping Luo IN: Nature Ecology & Evolution, 2024, https://doi.org/10.1038/s41559-024-02576-5

The net ecosystem exchange (NEE), determining terrestrial carbon sequestration capacity, is strongly controlled by climate change and has exhibited substantial year-to-year fluctuations. How the increased frequency and intensity of warm extremes affect NEE variations remains unclear. Here, the authors combined multiple NEE datasets from atmospheric CO₂ inversions, Earth system models, eddy-covariance data-driven methods and climate datasets to show that the terrestrial carbon sequestration capacity is weakened during warm extreme occurrences over the past 40 years, primarily contributed by tropical regions (81% ± 48%).
