ABSTRACT
In 2007, the IPCC listed glaciers of Andes as one of more vulnerable points of the Word, to the global warming, particularly those situated in tropical Andes. A reduction around 20% in last the twenty years is esteem and that in the current days the phenomenon comes being intensified because of the global climatic changes caused by the greenhouse effect. It is important to observe that there are the fountainhead of many rivers of the Amazonian basin. For glaciers located in Amazonian Andes, the forecasts indicate a sped up process of decline until the extinction. The Amazonia is not a place where science has the accurate knowledge of the hydrological and glacial events. In this context, appears the lack of a compatible database. At the same time, the absence of scientific knowledge with particular approach for basin of the river Amazon is perceived clearly, with capacity to become possible to understand and to monitor the processes of melting in course. This work intends to make a reflection about this problem and includes this question in the discussion, especially in the scope of the scientific community in the area of water resources.
