Understanding soil carbon’s sensitivity to increasing global temperatures
a,b, Total soil C stocks (a) and the proportion of total soil C that is protected (mineral-associated) (b) as a function of the mean annual temperature (MAT) globally. Each gridcell is colored by the percentage of clay and silt minerals, and best-fit trends are depicted for fine- and coarse-textured soils; here, fine-textured soils were classified as those with >70% clay + silt content and coarse-textured soils with <20% clay + silt content.…
