The effect of a dynamic soil scheme on the climate of the mid-Holocene and the Last Glacial Maximum
In order to account for coupled climate–soil processes, we have developed a soil scheme which is asynchronously coupled to a comprehensive climate model with dynamic vegetation. This scheme considers vegetation as the primary control of changes in physical soil characteristics. We test the scheme fo...
