Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. An increase in global temperatures can in turn cause other changes, including sea level rise, and changes in the amount and pattern of precipitation resulting in floods and drought. There may also be changes in the frequency and intensity of extreme weather events, though it is difficult to connect specific events to global warming.
Other effects may include changes in agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors.
Most national governments have signed and ratified the Kyoto Protocol aimed at combating greenhouse gas emissions.
