Extended Data Figure 2 : Annual mean high-latitude GPP (60° N–90° N) against the amplitude of the CO2 seasonal cycle at BRW for each of the CMIP5 ESMs.

Extended Data Figure 2

The markers show the values for the individual years between 1850 and 2005 for the CMIP5 historical simulations and lines show the linear best fit for each model. The black line indicates the multi-model mean of the CMIP5 models.
