Abstract: This paper presents the environmental implications of climate change on the coastal areas of the Niger delta located in the southern part of Nigeria. It gives a general overview of global climate change and predicts its consequences and examines how it has made the coastal areas of the Niger delta vulnerable to natural disasters such as flooding and others. The build-up of greenhouse gases in the atmosphere has led to an enhancement of the natural greenhouse effect. It is however deduced that human-induced enhancement of the greenhouse effect is of concern because ongoing emissions of greenhouse gases have the potential to warm the planet to levels that have never been experienced in the history of human civilization. Such climate change could have far-reaching and/or unpredictable environmental, social, and economic consequences. The Global warming has the tendency of establishing favorable atmospheric conditions for disease carrying vectors and making it possible for these organisms to spread diseases that are realized more harmful to beings.
