Abstract
We are at the edge of a disaster if we do not act », Ban Ki-Moon, General Secretary of United Nations, 2008. All the political personalities of the all countries of the world agree on a report today: our world is in full evolution. But twelve days in the Copenhagen climate conferenCce in 2009 were enough to sow the disorder between these countries and dividing them rather than to move closer them. The reason? Disagreements, competitivity, evolution and different needs and views of the future from about 170 countries. The objective was to keep the process of Kyoto (2012) on the line and sign a protocol.
Currently, global warming is the observed and projected increases in the average temperature of Earth's atmosphere and oceans. In the 20th century, the temperature rose about 0.6° Celsius, a very high number. It has been caused by the increase of greenhouse gas concentrations (water vapor, CO², methane, ozone). The greenhouse gases contribute to the greenhouse effect and its largest contributing source is the burning of fossil fuels leading to the emission of carbon dioxide.
Today, every people of the developed countries know what means the global warming but not every people in the world. We are hearing and observing the changes but citizens don not really know what they have to do to make it changing.
What are the risks? What should we exactly do to fix it and live in a better world? There are some questions without answers for each person, but for the politicians too. They were waiting for new answers and new agreements as we did, but the Copenhagen conference was a failure. The life on the planet Earth was doubtless born in the water there are 4 billions of years.
Water is dominating our life, our breath, our survival. It is the universal solvent, it has a big power of cohesion, it possesses a huge slowness in the temperature variations, it loosens a lot of energy passing from the liquid to the gaseous state. The fresh and good quality water is a rare resource too at the world level. Obviously, it represents in certain regions of the world a geostrategic stake.
