Global warming is a term used to refer to the phenomenon of 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.2
All data collections representative from ice cores, the growth rings of trees, etc.., Indicate that temperatures were warmer during medieval times, cooled tolow 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 century materialize, then the planet will experience an average global warming muchlike the one suffered at the end of the Ice Age wisconsiense (last ice age), according to the IPCC there is no evidence that any future global exchange rate has been matched in the last 50 million years by a temperature rise comparable.2
Global warming is associated with climate change may be anthropogenic cause or not. The main effect that causes global warming is the greenhouse effect, aphenomenon referred to absorption by certain atmospheric gases, mainly H 2 O, followed by CO2 and O3-energy part of the land issue as a result of being heated radiation solar.3 The natural greenhouse effect that stabilizes the Earth's climate is not a matter to be included in the debate on global warming. Without this natural greenhouse effect temperatures would drop buy approximately 30 ° C, with suchchange, the oceans would freeze and life as we know it would be impossible. For this effect to occur, it takes these greenhouse gases, but in suitable proportions. What worries climate scientists is that a rise in this ratio result in an increase in temperature due to heat trapped in the lower atmosphere
