Global warming to a significant increase in the average temperature of the atmosphere near the Earth's surface and oceans in recent decades, and is expected to continue. The global average temperature of the air near the ground during the last century. The Intergovernmental Panel on Climate Change, and concludes, "Most of the significant increase in the average temperature at the global level since the mid-twentieth century is very likely due to the observed increase in greenhouse gas concentrations synthetic," which leads to a rise in the temperature of the Earth's surface and lower atmosphere to increase the impact Inventories. Other phenomena such as solar energy and volcanoes that the difference probably had a warming influence of the pre-industrial to 1950, but as of 1950 lukewarm. Have adopted at least 20 scientific societies and academies of science, including all the national academies of science in the Group of Eight. Scientists disagree with some parts of this conclusion by geologists. However, few of these dissenting scientists specializing in climate science.
