Paleoclimatology is the study of past climates. Past climate can be reconstructed using a combination of different types of proxy records. These records can then be integrated with observations of Earth's modern climate and placed into a computer model to infer past as well as predict future climate. Since the beginning of human evolution, the climate and environment have been influencing social, economic, cultural and military activities. Human evolution was considerably affected by the climate changes from Pliocene and Pleistocene, as a result of the complex natural events. Paleoclimate represents the Earth's geological past climate. It was indirectly studied on the basis of ice distribution and composition, plants and animals’ fossils or relief characteristics. The study of the paleoclimate is an assessment and analysis source for the actual climate situation and for possible prognosis of future climate evolution. The climate modifications were more intensive at high latitudes. Consequently, it was chosen the sub-polar ecologic system to realize a complex analysis of the climate changes. In this context, it was studied the special literature, wherefrom there were studied and adopted some theories and mathematical models, were correlated with stochastic and experimental data obtained on the field, in order to find a modality to explain global climate changes. The volcano activity can affect the climate, on a global scale, for a long period of time. During millions of years periods, the increasing volcanic activity has generated enormous volumes of greenhouse gases, with a huge potential for global heating.
