Climate change is the unusual weather rhythm over a protracted period of time. It is unusual because, the change is a departure from the usual cycle of weather pattern. The unusual development rather than being for a while for a return to the normal pattern appears irreversible and hence a new threshold of weather factors. Such new threshold elicits reaction of both organic and inorganic forms and functions. Man at the peak of creation must react, adapt and respond consciously or otherwise, calculated or otherwise. This reaction, adaptation and response of man will determine the quality of life and continued existence of man on the earth.
