Global Warming

What is the global warming? 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. There are several causes of global warming. One of the main cause that is coming from carbon dioxide (CO2) which is released from greenhouses, industrial activities, the modern transportation. An increase in global temperatures can in turn cause other changes, including sea level rise and changes in the amount and pattern of precipitation. There may also be increases in the frequency and intensity of extreme weather events, though it is difficult to connect specific events to global warming. Other consequences may include changes in agricultural yields, glacier retreat reduced summer stream flows, species extinctions and increases in the ranges of disease-carrying insects.
