Another possible cause of the intensification of the effect greenhouse is the increase of the amount of creation animals, therefore its digestive processes produce nitrous methane and oxides. In the industrialized countries the debate around the question and its possible consequences is intense. Unhappyly the debate has been characterized for one strong ideological load. The ones that doubts that the human beings are responsible for the heating say that the temperature of the Land already had significant variations in the past. They mention the calls glacial periods, when the Land was supposedly well more cold of what now; e, to support the theory of the natural heating, evidences cites it of that at certain times in cold regions, as the Groelndia grew typical vegetation of hotter regions. However, the scientists admit that the more she comes back in the time, more difficult are to affirm as it was the climate. However, the fact is that radical climatic changes and in global level had occurred in a remote and also recent past Therefore, this article deals with the questions of global the climatic changes and the Amaznia.
It is tried to contribute to the debate when bringing the quarrels of some elements that frequently are being forgotten, as the perspectives it geologic time and global changes it past, as well as transformations that lead to the climatic variations of the AMAZNIA. 1.1Geologia and the global changes of the Past geology has a basic paper for these studies of global changes, it has as objective to show in details as everything started as Professor Toni Tapani Eerola explains ' ' (…) Geology is the science of the changes. The events of our planet had been recorded in layers of sedimentary rocks, that are chores and interpreted by the geologists. The processes and the related geologic changes cover thousand, millions or until billions of years.
