Intergovernamental
In first place, he would like to alert it not to believe everything that is published by pertaining organizations the ONU, therefore, many times, such actions and orientaes have the objective to make with that countries of first world continue to keep its hegemony, in economic and technological terms. This seems to be the case of the IPCC (Panel Intergovernamental de Climatic Mudanas), ONU, that has dealt with emissions of gases and that ' liberated its recently; ' Third Assessment on Climate Change' ' (3 evaluation on climatic changes) that it increased, still more, the estimates of increase of the globe temperature if the Co2 concentration and other gases deefeito-greenhouse to fold, now varying of 1,5 C 5,6C. Figure 10 of the Summary Technician of the proper IPCC sample that, for last the 17 years, had a trend in the concentration of methane (CH4) of -0,09% to the year, what it means that its growth has been negative and that the CH4 concentration will be able to be stabilized in 2005 and to diminish from this year, although the flocks of ruminants to have exactly grown in this period. The taxes of Co2 increase also have decreased, passing of 0,45% to the year in the start of years 1980 for 0,41% to the year at the beginning of years 1990 (0,04% decrease), while the emissions 5,4 human beings had passed of Gigatoneladas of carbon (GtC) for anopara 6,8 GtC/year, an increase of 26% in the same period. The concentrations of these gases of effect-greenhouse depend very on the temperature of the oceans that cover 71% of the planet.
The oceans are the great reservoirs of these gases, contend, for example, about 60 times more Co2 that the atmosphere. When the oceans are hot, the absorption of gases diminish, when they cool the absorption of gases increase. Thus, a small cooling of the temperature of the oceans to completely change the projections made for the IPCC would be enough on the global heating.
