Fuel Burning

For the fsseis fuel burning that produces the emission of gases dioxide of sulphur (SO2) and nitrogen oxides (IN and the 2) and can empobrecer the ground causing damages the monuments and increase the acidity of the rivers. The climatic desertificao, alterations such as bigger hurricane incidence, tufes and cyclones and also increase of heat waves are other consequences of the global heating. The climatic alterations had to the global heating can affect, for example, the reproduction of many types of vertebrates, dries inhibits the reproductive activities of many types of amphibians and some reptiles (ORR, 1986, P. 490). During the introduction of this production of the knowledge we cite what the scientists call ‘ ‘ islands of calor’ ‘ , therefore the more cemented, concretada and tarred it is an area of the city, hotter it is, therefore these materials according to Guide of Estudante and Atualidades store heat they return it to for air in the form of thermal radiation. In areas in which it has ground displayed, plants and trees, these absorb the heat without practically refletiz it in return for the atmosphere. Moreover, still they cool to the environment returning the water of rain for the evaporation, therefore one of the physical properties of the water is to be always more cold than air. According to Cortez, throughout the geologic history of our planet glacial and interglaciais periods had been intercalated (period between two glaciations) as the current interglacial period that already lasts about 10 a thousand years, being a normal cyclical process. But the true current problem is in the fact of that the action human being comes increasing the calls gases greenhouse speeding up a process of climatic changes that can modify all seriously the ecosystems of the planet. A curiosity is that the gases greenhouse such as carbonic gas, methane, diverse clorofluorcarbonetos and nitrous oxide amongst others thus is called why they allow that the solar light crosses atmosphere hindering that the heat has escaped for the space.
