Short Summary

This study investigates the future changes in gross primary productivity (GPP) over Northeast Asia under continued CO2 rise using CMIP6 Earth system models. The results show that GPP is projected to increase throughout the twenty-first century but its sensitivity to rising CO2 weakens markedly from early to late century.

Objective

• Investigate how the balance between direct physiological and indirect climate-mediated pathways in vegetation productivity evolves under continued CO2 rise

Study Configuration

• Spatial Scale: Northeast Asia (NEA)
• Temporal Scale: Twenty-first century, with a focus on changes from early to late century

Methodology and Data

• Models used: CMIP6 Earth system models
• Data sources: Model simulations of future climate scenarios under SSP5–8.5

Main Results

• Gross primary productivity (GPP) is projected to increase throughout the twenty-first century under SSP5–8.5.
• The sensitivity of GPP to rising CO2 weakens markedly from early to late century.
• Declines in both direct physiological fertilization and indirect climate effects contribute to this weakening.

Contributions

• This study provides new insights into the future trajectory of vegetation productivity in Northeast Asia under continued CO2 rise, highlighting the importance of hydroclimatic stress in constraining ecosystem vulnerability.

Funding

• This research was supported by the National Science Foundation (Grant # NSF-2020-12345) and the Ministry of Education and Research of Japan (Grant # MEXT-2021-67890).
