Indiceemissions of greenhouse gases. At last report with projections presented by IPCC climate models indicate that it is likely that global surface temperature, increase from 1.1 to 6.4 ° C (2.0 to11.5 ° F) during the XXI century 0.5 They have proposed several measures to mitigate climate change, adapt to it or use geoengineering to combat its effects. The most relevant international agreementon global warming has been the Kyoto Protocol, which aims at stabilizing the concentration of greenhouse gases to avoid "dangerous anthropogenic interference with the climate system" was adopted at 6Framework Convention United Nations Climate Change and promotes a reduction of pollutant emissions, mainly CO2. Until November 2009, 187 states have ratified the United protocolo.7. States., Largestemitter of greenhouse gases worldwide, 8 has not ratified the protocol. | Global warming is a term used to refer to the phenomenon of rising global average temperature of Earth's atmosphere and oceans,possibly reaching the level of heating of the Middle Ages to the mid twentieth century, to exceed it from entonces. All data collections representative from ice cores, the growth rings of trees,etc.., Indicate that temperatures were warmer during medieval times, cooled to low values ​​during the XVII, XVIII and XIX and then heated again rapidez.2 When studying the Holocene (last 11.600 years),the Intergovernmental Panel on Climate Change (IPCC) shows no evidence that there were global annual average temperatures warmer than actuales.2 If projections of a warming of about 5 ° C this centurymaterialize, then the planet will experience an average global warming much like the one suffered at the end of the ice Age wisconsiense (last ice age), according to the IPCC there is no evidencethat any future global exchange rate has been matched in the last 50 million years for a comparable temperature rise.Global warming is associated with climate change may be anthropogenic cause or not....
