Respiration‐Induced Weakening of Land Sink Contributed to the Largest <scp> CO <sub>2</sub> </scp> Increase in 2024
in 2024, which was caused by hotter and drier conditions leading to a larger increase in respiration than photosynthesis. Our findings underscore the urgent need to investigate the mechanisms behind the declining carbon sink amid persistent global greening. These results challenge previous assumptions about the long-term stability of the terrestrial carbon sink and highlight society's growing dependence on adaptive strategies to mitigate climate warming.
