The consequences of climate change are not only limited to the lithosphere, but to all components of the geosystem which include the atmosphere, the hydrosphere and biosphere. Indeed human activities will be affected, particularly the agricultural production due to the rising temperatures, increase in rainfall and the changes in wind circulation. The interactions within the geosystem will be affected by the changing climate. For instance, the atmospheric carbon dioxide is a crucial factor in determining global temperatures and its concentration in the atmosphere is partly controlled by the rate of weathering reactions on the landsurface; this in turn, is influenced by a range of geomorphic factors. The global warming due to increasing temperatures will not be globally uniform but will differ significantly between geographical regions. In addition, the warming may vary between seasons. As a result, the altered temperature gradients will change the pattern of winds and precipitation distribution regionally.The changes in the climate will have tremendous effect on both the magnitude and frequency of geomorphic processes. Extreme climate change can alter the land surface processes, and induce disasters such as landslides, floods, drought and others.The consequences are discussed in the next section on Geomorphological Responseto Climate Change.
