Abstract

Recent studies attributed the accelerating land carbon sink (S-LAND) during the 2000s to respiration decrease induced by the warming hiatus. We used two long-term atmospheric inversions, three temperature data sets, and eight ecosystem models to test this attribution. Our results show that the changes in seasonal S-LAND trend between the warming (1982-1998) and hiatus (1998-2014) periods do not track evidently the changes in seasonal temperature trends at both global and regional scales. A conceptual model of the annual/seasonal temperature response of respiration suggests that changes in seasonal temperature during this period are unlikely to cause a significant decrease in annual respiration. The ecosystem models suggest that trends in both gross primary production and terrestrial ecosystem respiration slowed down slightly, but the resulting slight acceleration in net ecosystem productivity is insufficient to explain the increasing trend in S-LAND. Instead, the roles of alternative drivers on the accelerating S-LAND seem to be important.
