CLIMATE IN THE FUTURE.

In the short term, is more acute the effect of global warming looming in greenhouse gases, caused largely by human action. These gases have risen since the industrial phase of human significantly: The third has increased CO2, methane has doubled, and nitric oxide has grown by 15%. If only this increase continues, it is estimated that in 100 years the Earth average temperature will increase between 2 and 5 degrees. This overall increase in temperature would bring major consequences: loss of forest fires in the forest, so that means, changes in precipitation with an atmosphere more unstable, with frequent storms and floods, increased evaporation and thus of aridity, melting glaciers with a consequent rise in sea levels, flooding of coastal regions with their cities, salinization of coastal aquifers; mass death of coral reefs ... There are opinions that suggest that the problem is not so alarming: forests absorb excess CO2 and above all, oil will be exhausted by 2100 and will lower greenhouse gases significantly. But it is prudent not to play with a very delicate and interconnected with the biosphere as the climate and it would be possible to reduce human emissions of greenhouse gases from industries and transport. One solution is the gradual replacement of "dirty energy", based on fossil fuel, "clean energy", no contaminants, such as wind, solar, hydro, biomass, and above all, to investigate and capitalize on other energy, cleaner and more powerful, such as fusion, which is the energy of stars, among others.
