Scientist such as Fourier (French) and Arrhenius (Swedish) explained the Earth’s greenhouse effect and the role played by some atmospheric gases such as CO2 and methane (CH4) in warming our planet (Fleming, 1998). Around the same time, Arrhenius, together with Chamberlain, an American scientist, realised that the burning of fossils fuels could lead to global warming. Indeed there is increasing evidence from work that have been carried out over nearly two decades by the IPCC, which cements the conclusion that global warming and subsequent climate change are largely due to human activities. However, there continues to be considerable debate regarding the causes of climate change, that is, whether it is included by anthropogenic activities or simply within the range of natural variability in climate.
