Global Warming

From 1981 to 1990, the global average temperature compared to 100 years ago has rised 0.48 ℃. The main reason of the global warming is that people over spend fossil fuel (for example coal, petroleum and so on) in a nearly century and discharge a large volume of CO2 and many other kinds of greenhouse gas. Because the greenhouse gas has a high permeability of the solar radiation visible light, and high absorption of the long-wave radiation which reflects to the Earth , as is often says " the greenhouse effect", causing the global warming.

The consequence of global consequence can cause the global precipitation to redistribute, the glacier and the frozen to melt, the sea level to promote. It will harm the balance of natural ecosystem, threaten humanity's food supply and living environment.
