  Supplemental Figure 1. The United States and Europe have developed a disproportionately large number of terrestrial biosphere models (TBMs). This cartogram skews the country size by the number of TBMs developed, as defined by the country address of the corresponding author on the first reference for each respective TBM shown in Supplemental Table 1.

  Supplemental Figure 2. Sensitivity of the terrestrial biosphere net biome production in the CLM4.5 model to varying CO2 (green), nitrogen (N) deposition (purple), climate (blue), and land use and land cover change (red). The effects are shown as zonal sums averaged over 1982–2010, with the global totals inset. CO2, N deposition, and climate changes in the high latitudes lead to net carbon uptake, whereas climate changes in the tropics and land use and land cover change globally lead to large carbon emissions in CLM4.5. The net integral of all drivers globally produce a total of 0.01 PgC/year uptake.
