The atmospheric concentration of natural greenhouse gases has increased steadily since the industrial revolution. Soil scientists and ecologists recognize the importance of the global carbon cycle and its role in the greenhouse effect. Global Climate Change and Pedogenic Carbonates explores the potential of world soils to act as a sink for atmospheric carbon. Understanding the extent of this potential requires a thorough knowledge of the magnitude and nature of soil carbon pools and their dynamics in different ecosystems. The soil carbon pool plays an important -and well recognized - role in the global carbon cycle. It is not yet clear how and under what conditions this pool can be influenced by human intervention, especially the large inorganic carbon pool that occurs largely in arid regions. Global Climate Change and Pedogenic Carbonates summarizes what we know about soil inorganic carbon and develops strategies that could lead to the retention of more carbon in the soil. It covers basic concepts, analytical methods, secondary carbonates, and research and development priorities. With this book you will get a better understanding of the global carbon cycle, organic and inorganic carbon, and their roles, or what we know of them, in the greenhouse effect.
