Global warming is a rising of the oceans and of the air medium temperatures near the Earth´s surfice that is happening since the 20th century and it should continue during the 21st century,The most part of the temperature observed since the mid of the 20th century were caused by concentrations of the greenhouse gases as result of human´s acts such as deforestation and the burn of fossil fuels.
The rise of the global temperatures can and will cause some changes, including the rising of the sea levels, changes in the percipitation patterns resulting in heatwaves and floods. The scientist predict that the most significant heating be in the Artic and it will be associated to the retreat of the ice.
Other probable effects are alterations in the frequence and intensity of the extreme wether events, and the extinction of spicies and variations in the agriculture productions. The global warmin and it consequences will change according to the region.Other global consequence that will happen because of the global warming that is already happen is the ocean acidification.
The Quioto conference aims the stabilization of the concentration of greenhouse gases to avoid some serious consequences.In November already 187 countries had assined the Quioto protocolo.
. We can do several things to avoid the global warming, simple things.For example we can and should disconet the plug of electronic divices that are not being used, we can avoid the abuse of energy for heat or houses. Besides wath is already refered we can also use the machines that have the stamp of being environment good we can also walk inseted of go on a car that doesn´t hepls just the environment also helps us.
