It is no exaggeration to say that climate change has been a serious global problem which influences the whole world. The main driver of climate change is the greenhouse gases in the atmosphere. The greenhouse gases stop some of the heat from escaping the atmosphere, which in turn causes change in climate. Some greenhouse gases are neutral but many of them are manmade. With the outstanding industrial development, more fossil fuels such as coal, oil and natural gas are used and burnt, which release carbon dioxide and methane into the atmosphere. Deforestation also produces a lot of carbon dioxide. In fact, many scientists believe that man's activities are making the natural greenhouse effect stronger.
Indeed, due to the climate change,

Actually Australia has enormous renewable energy resources in the form of sunshine, wind, biomass residues, hot rocks and waves. Australia's advantage in many alternative sources of energy is inherent, deriving from our large land area, sunny climate and long coastline. However, Australia is still highly dependent on fossil fuels. In fact, Australia is particularly well placed for the longer term global energy revolution. Australia should seize the opportunity at an early date to build on Australian expertise already acquired in areas such as energy efficiency and solar technology and move early to reduce the long-term costs of conversion to non-fossil-fuel sources. But the Australian Government's position on climate change has taken in the opposite direction, emphasizing short-term economic goals and entrenching fossil fuels in the nation's energy economy.
On the other hand, the issue of cutting greenhouse gases emissions become a intractable problem because there is always a debate between scientists and economists. Economists state that cutting off carbon dioxide emission will damage the world economy and introduce serious
