Extended Data Fig. 1: Summary of the selected components of land CO2 fluxes in IAMs, DGVMs and NGHGIs, and areas of managed and unmanaged forest and of intact and non-intact forest28,52.
From: Critical adjustment of land mitigation pathways for assessing countries’ climate progress
Values are approximated (broadly based on the averages for 2005-2015) with the purpose to illustrate where the main differences are between IAMs and NGHGIs, that is not much on direct effects, but rather on how indirect effects are estimated and labelled (if anthropogenic or not). As a result, when considering a broadly similar area of forest (that is about 3 billion ha of non-intact forest), the sum of CO2 fluxes by global models (IAMs and DGVMs) match well those from NGHGIs. Numbers in parenthesis indicate values not included in the original IAM and NGHGI datasets, but estimated here (see footnotes).
