In the recent past, there has been adverse effects of climate change leading to global warming within the South African ecosystem and thus affecting many sectors of the economy such as tourism, agriculture among others. The source of raw materials has been affected by the poor climate impacts. It has become a major factor in policy making since climate change will have a great impact on the key sectors in South Africa, namely water, agriculture, and biodiversity. This increase in average temperatures will greatly influence water resources, food security, health, infrastructure and the environment, which includes biodiversity and the ecosystems. Carbon dioxide is the main cause of human-induced climate change. It has been emitted in vast quantities from the burning of fossil fuels and it is a very long-lived gas, which means it continues to affect the climate system during its long residence time in the atmosphere.
