(4) Now compare the latitudinal patterns of carbon storage on land in the following figure. The areas above 0 on the y axis is carbonstorage above ground, and the areas below 0 on the y axis is carbon storage below ground (or soil organic carbon SOC for diflerentdepths shown in the figure caption). Summarize the similarity and differences between the two (5 pt), explain what proce cesses drive thesimilarities and differences (5 pt). How would we predict future changes in carbon storage under the direct influence of CO2 rise andglobal warming (5 pt)?

The latitudinal patterns of terrestrial carbon stocks, both aboveground living plant biomass (green) [data from Gibbs et al. (114)] and soil carbon stocks (brown) [data from Hengl et al. (18)].
