工业化排放的污染（Industrial emissions pollution） Industrial emissions of polluting gases have also made cities inhabited by humans a particularly high concentration of air pollution islands...... Humans also rushed down the enormous disaster in economic development, improve the quality of life at the same time. Many disasters seem to be natural disasters, and actually are often caused by human beings themselves man-made. The destruction of the earths atmosphere is a terrible revenge for mankind, and nature will never forgive mankind for ignorance. In June 1992, heads of state and government gathered in the Rio de Janeiro, Brazil, to sign the United Nations Framework Convention on climate change. Why would such a common scientific problem such as climate change become so interesting? It turned out that since the industrial revolution, the amount of carbon dioxide (CO2) in the global atmosphere has increased by 25% in the past hundred years as a result of the burning of fossil fuels and destruction of forests. If the current CO2 concentration increases, the CO2 content in the atmosphere will double by 2100. According to the assessment report issued by the United Nations, then the global average temperature will rise by 1 to 3.5 DEG C than now, this will cause the polar ice melting, sea level rise to 15~95 cm, which flooded the economically developed coastal areas, but also may cause a series of serious problems. Governments around the world are beginning to attach importance to the situation and its consequences, and discuss the issue of reducing CO2 emissions. What is the greenhouse effect? The global average ground temperature is about 15 degrees centigrade. If there is no air cover, released into space according to the principle of earth to obtain the heat of the sun and the earths heat equivalent, can calculate the average temperature of the earth surface is 18 o C. The temperature difference of 33 degrees is that the atmosphere protects the earth like a quilt. This is th
