Brief introduction about global warming

Global warming is one kind of natural phenomenon in this world. Due to humans usually burn fossil minerals to obtain energy and hew forest to gain woods for survival and then burn them down for many living uses, in the process of these activities from human being, all kinds of greenhouse gases mainly including carbon dioxide are released which bring about great effect on the global weather (Blake, D. R. et al, 1988). As these gases have highly permiability for the visible light from the sun radiation and highly absorbent  for long-wave radiation reflected by the earth, they can strongly absorb infrared rays from the earth radiation. This process is often called by scientists "Greenhouse Effect" which directly and fatally leads up to global warming. Global warming will give rise to a large number of consequences such as redistribution of global precipitation, melting of glaciers and permafrost, rise of sea level. These consequences not only bring harm to the balance of natural ecosystems, but also it poses bigger threats to food supply and living environment of human being. It is reported that global warming refers to a period of time during which the phenomenon of increasing temperature of the atmosphere and the ocean takes place. The main reason for it is the activities of human being, which result in over emissions of greenhouse gases produced by human activities and carbon dioxide is the representable greenhouse gases (Kbalil, T . A . G., et aI, 2005).
