Description :
There is much interest in predicting future carbon-soil degradation and that occurring today. The AA. consider the National Soil Survey Laboratory data to assess some of the soil carbon degradation in the Great basin and western Utah, and include data on 32 Nevada and Utah soils on Pleistocene geomorphic surfaces at elevations of 973 to 3172 m. They study the correlation of mean annual precipitation (MAP) and mean annual soil temperatures (MAST) with elevation. Increasing the temperature by 3°C will likely also increase the area affected by severe desertification in the southern Great Basin north by about 20%.
