Response of Terrestrial Net Primary Production to Quadrupled CO₂ Forcing: A Comparison between the CAS-ESM2 and CMIP6 Models.

ABSTRACT: Terrestrial net primary production (NPP) is a key carbon flux that changes with rising atmospheric CO₂ and CO₂-induced climate change. Earth system models are commonly used to investigate these NPP changes because of their fundamentally trustworthy ability to simulate physical climate systems and terrestrial biogeochemical processes. However, many uncertainties remain in projecting NPP responses, due to their complex processes and divergent model characteristics. This study estimated NPP responses to elevated CO₂ and CO₂-induced climate change using the Chinese Academy of Sciences Earth System Model version 2 (CAS-ESM2), as well as 22 CMIP6 models. Based on CMIP6 pre-industrial and abruptly quadrupled CO₂ experiments, the analysis focu
