Error estimates are given as the mean from two threshold approaches (see Methods) ±an error of 0.5% from ref. 16 to our woody vegetation carbon estimates (*). Note that for estimates that only consider aboveground biomass, roughly 20–60% needed to be added to account for belowground biomass carbon16.
$ Estimate only includes aboveground biomass carbon.
• Estimate only includes woody biomass carbon.
e Estimate includes environmental influences.
a Estimate includes anthropogenic influences.
