"RESPONDING TO 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.
              Climate change is a major issue affecting the world and is most commonly referred to by the public as "GLOBAL WARMING" and the change in the average pattern of weather over a long period of time.It is widely believed that climate change is the direct result of human civilization.If climate change is caused by humans, they cannot be held solely accountable.Natural factors such as volcanic eruptions, ocean currents, earth's orbital changes and solar variations, are extremely influential in climate.
