Climate Change


          Climate change is a tangible problem and its existence can no longer be denied. It is one of the most important scientific, economic threats facing to the earth. There are many factors lead to climate change, such as greenhouse gases, carbon dioxide, fossil fuels. Although it would be self-deception to believe that humans had nothing to do with it, the fact is that human activities caused negative effects on climate change. More people exploit more natural resources, cut more trees, use more fossil fuels, produce more wastes, build more roads, dams and cities, pollute more soil, water and air, and contribute more greenhouse gases to the atmosphere, which may lead to the ozone depletion and global warming, i.e., ultimately damaging the entire environment and annoying the climatic change. Thus, man is capable of influencing global climate deliberately or inadvertently through his various actions and activities.

          Because CO2 and other greenhouse gases are so long-lived in the atmosphere, enhanced greenhouse warming can be expected to persist for centuries. The impacts - many of which are effectively irreversible - will affect everyone on earth. Human health, patterns and intensity of precipitation, water and food supplies, coastal development, energy supplies, and the viability of natural systems: all will be affected if Earth's climate continues to change.
