According to the 4th assessment report, there is proof that Africa is warming quicker than the global average, and it is likely to persist. It is projected that by 2100, temperature changes will drop in ranges of about 1.4 to almost 5.8˚C rise in mean surface temperature contrasted to 1900, and around 10 to 90cm increase in mean sea level. This warming is most over the heart of semi-arid boundaries of the Sahara also central southern Africa. Before the atmospheric amount of carbon dioxide equivalent has multiplied by two, the worlds mean precipitation is anticipated to be around 1-5 % more than 1900. Under the least warming situation, equatorial east Africa will have rainfall increase by 5-20 % during December, January as well as February and diminish by 5-10 % during June, July also August (Schreuder, 2009, p.39).Agricultural production with foodstuff security in most areas of Africa is likely to be strictly compromised by climate change, as well as climate variability. Climate change will deteriorate the water stress presently faced by some nations. while some of those nations, presently not at risk of water stress, will be affected. Changes in an array of ecosystems are by now being noticed faster than expected, mainly in the Southern African environments. Climate change and unpredictability could also lead to the flooding of low lying lands, comprising coastal settlements. Human health could also be more negatively affected by climate change with climate variability, for instance, there has been a rise in the frequency of malaria in southern Africa as well as East African highlands. These unfavorable effects together with poverty, institutional frameworks and Poor policy, cause Africa to be one of the most susceptible continents to climate change as well as climate variability.
