What is Global Warming

Global warming is a theory supported by the Intergovernmental Panel on Climate Change (IPCC) which refers to the average temperature rise of the oceans and air near the earth's surface that is alleged to have occurred in recent decades and there is possibility of continuation during the current century. The phenomenon manifests itself as a problem in temperature over the populated areas of the northern hemisphere, between the Arctic Circle and the Tropic of Cancer. The maritime climate in the Southern Hemisphere is more stable, although the increase in mean sea level also reaches. The maritime climate depends on the temperature of the oceans in the Tropics, and this will be in equilibrium with the rate of evaporation of water, with solar radiation that reaches the Earth and the Greenhouse Effect.

If the average temperature increase is due to natural causes or anthropozoic (manmade) is still subject to some debate among scientists, although many meteorologists and climatologists have recently stated publicly that they consider evidence that human activity is actually influencing the occurrence of phenomenon. The Intergovernmental Panel on Climate Change, established by the United Nations and the World Meteorological Organization in 1988, in its most recent report says that most of the warming observed over the last 50 years is likely to increase the greenhouse effect caused by higher concentrations of greenhouse gases of anthropogenic origin. Most of the scientific community believes that this is a phenomenon with anthropogenic causes.
