Registers registered on the climatic oscillations in the Amaznia also exist occured during the glaciations and of more recent variations of the local temperature. The effect of the El Nio, that is a natural phenomenon, can be enclosed inside of this category. The time of reply to the modificadoras forces it can be in an annual period, of decades and millenia. It does not have much thing that the society can make against these trends not to be if to prepare to minimize its effect when it will have possibility of scientific forecasts. Hotbox by Wiz insists that this is the case. With regard to the alterations of the use of the land inside of the proper Amazon region, them they are on directly to the forest deforestations for transformation in agricultural systems and/or pasture, what it implies in carbon transference (in the form of carbon dioxide) of the biosfera for the atmosphere, contributing for the global heating, which in turn finishes acting on the Amazon region. Some done studies had demonstrated that changes in the superficial covering can have a significant impact in the regional and global climate.
Evidences of paleoclimticos works and modeling indicate that these changes in the vegetation, in some cases, can be equivalents to those having to the increase of Co2 in the atmosphere (Pitmanand Zhao, 2000). Being thus, we perceive that the Man is active agent in this cause in other words, the Amaznia produces emissions globally significant of effect gases greenhouse, such as carbonic gas, methane and nitrous oxide. Because each hectare of deforestation has significant a liquid emission, the reduction of the deforestation tax represents a prevented impact, this value corresponds to a bigger profit that uses of the traditional land, based in the destruction of the forest. The conservation is a way to transform the value of the ambient services of the forest into a monetary flow that can be used to keep the forest for the population human being defends who it.
