a Total n-alkane content in the Nanglalu. b Total organic carbon (TOC) in Nanglalu44. c BrGDGTs-based temperature reconstruction for Nanglalu, with the shaded area representing the 95% confidence interval. d Integrated analysis of TOC across the Tibetan Plateau, with the blue curve representing the Generalized Additive Model (GAM) fit and the shaded area indicating the 95% confidence interval. e Integrated analysis of pollen concentration across the Tibetan Plateau, with the red curve representing the GAM fit and the shaded area indicating the 95% confidence interval. f Global CO2 reconstruction39. In a–f, the blue gradient bar highlights the Early to Mid-Holocene period. g, h Equilibrium and transient simulations of organic carbon stock, respectively, based on the ORCHIDEE model in this study. i-l. Linear trends from the early to late Holocene for temperature (i), net primary productivity (NPP) ( j), heterotrophic respiration (HR) (k) and NPP-HR (l). Results for NPP, HR and NPP-HR are from transient simulation.
