Extended Data Table 2 Summary data for changes in extratropical GPP (30° N–90° N) and the amplitude of the CO2 seasonal cycle at KMK

From: Projected land photosynthesis constrained by changes in the seasonal cycle of atmospheric CO2

  1. The fractional change in extratropical GPP was calculated from the 1%BGC simulation for a doubling of CO2 and is listed for each CMIP5 ESM. The regression coefficients result from a linear regression model for the change in the CO2 amplitude at KMK (see Methods). Regressions are calculated using the full length of the records available from the CMIP5 historical simulations (1860–2005) and the KMK observations (1979–2015).
