Global warming is the greenhouse effect that is brought about by emission of carbon into the atmosphere. When fossil fuels burn, carbon dioxide is released into the  atmosphere. Carbon together with other greenhouse gases forms a layer that allows visible light from the sun to reach the atmosphere but prevents degraded infrared radiations from escaping back into space (Bruce, 2002). The radiations are irradiated back to the earth surface resulting in accumulation of heat raising the temperature of the atmosphere.Global warming has had a number of effects to the atmosphere, world economy, environment and health as well. This has brought along with it consequences such as floods, droughts, wild fires, tsunamis and other nature events of great magnitude (Robert, Scott  John 2009).
 Human beings have been directly exposed to climatic changes through change in weather patterns and water levels which have had effect on their air and quality of food. There are also changes in ecosystems, agriculture, commerce and settlements which in return have had effects on the economy (Stuart, 2005).

Some regions such as the north and the South Pole have also been adversely affected leading to the increase in sea level. Because of that increase, some islands have been submerged leading to migration of people in search of alternative land.

Climatic changes have affected the health status of people leading to malnutrition, increase in deaths and injury brought about by extreme weather conditions.

Due to the increased carbon dioxide in the atmosphere, there is increase in hydrogen ion levels in the ocean water brought about as a result of excess carbon dioxide dissolving in ocean water, which has led to a decrease in ocean PH (Global Warming Both Sides, 2003). Since the aquatic life is sensitive to changes in PH and temperature, it may lead to changes in distribution of certain organisms and death of others. These organisms may die as a result of depletion of oxygen as a result of saturation of ocean water by carbon oxide.
