This paper is about how and by what ways climate change affects human migration. The world at large is expected to face crises of dual nature. In the first place, excessive fossil fuel consumption would result in environmental degradation. Among others, people would be faced with serious food crises as well as reduced income. In the wake of environmental change, people will migrate in search of better income prospects and food security. There is no doubt that there a strong but direct relationship between climate change and human displacement. This displacement may either be long distance or a short distance in other cases. If it is a short distance, there is a possibility that it will be temporary, and as soon as the climate change event is over, people may return back to their habitats. It may be a long-distance if climate change-related event takes place on regular intervals over a long period of time. Data is collected through secondary sources.
