What makes soils different from one another?

Soil scientists describe soil as a natural body that forms as the result of five factors: Climate, Organisms (plants, animals, and microorganisms), Relief (shape of the landscape), Parent materials, and Time. This can be explaines as a function as follows.
S = function (Climate, Biota, Slope (Relief), Parent material, Time)
These five factors are referred to as ClORPT, for short (kind of a mnemonics).

Does climate change affect soil? 
Anthropogenic climate change is already occurring and will continue to be a significant threat. Regardless of national and international efforts to mitigate the effects of rapidly increasing greenhouse gas emissions, significant climate change is  highly likely to occur over the next century. Recent projections include at least 2° to 3° of warming by 2050 in many parts of the world, as well as large changes to rainfall distribution and seasonality. There are likely to be significant impacts on all ecological systems as a result of these changes.  Projected climate change has the potential to have severe, but variable, impacts on soils, depending on the bioclimatic zone and the intrinsic vulnerability of the soils in that zone. Changes to land use and management as a result of climatic shifts will also potentially affect soils. To develop a climate change scenario for soils on a regional basis, it is necessary to consider several factors and this article/page highlights some vital information on that subject
