Until year 2007 one discussed much on if there were guilty for this perceivable process already in many zones of the Earth, reason why it became necessary that scientists worldwide compiled that same year the Climatic Report, putting light in a sea of opposed opinions. The answer to the question was, yes, the culprit is not other that the human being. Nevertheless many skeptics perhaps not wanting to accept the responsibility and responsibility of so dramatic future, allege that only Earth is a natural process more in the history of the planet. In spite of this, the worrisome thing is that the intergovernmental Group of expert on the climatic change has foretold numbers already: in best of the cases the temperature it will raise between 1,1 and 2,9 Celsius. But meanwhile new recognitions have arisen that show that the development of the climate has taken a much more drastic direction than was foretold in him climatic report of the referred year. The signals that they indicate that the humanity has arrived already at the limit of the sustainable point of the climate or that has even exceeded already it, they are evident. For example it has been corroborated that the ascent of the level of the sea, that the experts had calculated in a maximum of 59 cm., will be much more dramatic since defrosting is taking place more express than it had been foretold. The director of the Institute of Postdam for the investigation of the climate, professor Joachim Schellenhuber said very textually: " In fact, we must prepare us for an increase of the level of the sea of 1 M. during this siglo". On the other hand the methane, that is a gas that contributes to the greenhouse effect and that is 25 times more detrimental that carbon dioxide, has increased remarkably from 2007, between the reasons is the intensive cattle ranch, but also that the grounds of permafrost of Siberia defrost more and more, releasing it to the atmosphere.
