Since the late nineteenth century, the view that global climate change is directly influenced by human behaviour has become increasingly accepted as scientists have provided better evidence for the relationship between the level of global carbon dioxide concentrations and global temperatures. A large number of natural phenomenon and processes are affected by climate change, and these in turn can have a negative impact on groups of people living around the world; i.e. The melting of the ice-caps is responsible for the decrease in the number of polar bears in the arctic, rising sea levels increase the risk and regularity of floods in low-lying areas like Bangladesh, and the Inter Tropical Convergence Zone failing to reach Niger, Chad and Sudan was responsible for a large prolonged famine in the 1980s. The magnitude of the number of countries affected mean that climate change is not just applicable to one nation; it is of international importance.
Therefore, as climate change has increasingly become a global issue in recent years, a number of international organisations have been formed to monitor global climate change and to reduce and possibly reverse global climate change. International efforts incorporate a greater number of people than national efforts, and therefore they can have a much larger impact on trying to tackle climate change. However, tackling climate change is expensive, and for certain less economically developed countries- (LEDC’s), it would be unreasonable to insist that they should prioritise tackling climate change over some of their national problems, such as lowering the infant mortality rate and establishing a good healthcare system. Furthermore, international efforts to tackle climate change also face problems from the disparity of natural resources, which means that different solutions have to be used in different countries.
