The Hydrological Strengthening Mechanism of the Global Warming Process.

The ongoing global warming process and its consequences is usually studied with the gas emission inventories approach [1-3 with the consequent assessment of atmosphere CO2 equivalent rising that lead to the increasing of mean global air temperature. This approach does not include the role of additional factors as the non linearity in the relationships among the energy budgets, land coverage and global water cycle. Some studies point out that the role of these concurrent factors may be at least of the same importance as the one played by CO2 equivalent emissions as driven forces in the global warming processes [4, 5. The increasing of air temperature is a widely accepted fact. Major questions are related to when and how a stabilized climate will be reached, how to mitigate and adapt itself to the global warming consequences. To answer these questions efforts considering the complex interactions of the earth albedo, evaporation from land surfaces, air humidity and their influences over the global energy and water balances must be studied. At the same time, water resources are studied applying a deep statistical description of global surface runoff [6-12, then, any formulation of hydrological scenarios related to climate change forcing factors is usually done in terms of probabilities [13-16. Bringing these two approaches together could help in understanding the emergence of water cycle chaotic patterns and the global, regional and local strengthening of climate change due to the nonlinear interactions between water and energy budgets. The building of rainfall runoff stochastic models is becoming a widespread tool to access water resources.
