Climate change refers to a change in global temperatures and precipitation over time due to natural variability or to human activity and it also has the potential of affecting all natural and human systems and may be a threat to human development and survival socially, politically and economically. This paper assesses how the Nigerian government and its citizen are prepared in adapting and mitigating this global environmental phenomenon. This review paper contends that climate change may already be impacting Nigeria as manifested by increased flooding, delayed rains, enhanced desertification, increasing bush fires and food insecurity. The government of Nigeria has made significant progress in addressing the problem of climate change through preparing, demonstrating, negotiating, collaborating and developing various policies, programs and plans at national, regional and international level. Despite all these, climate change is still on an increase. Although Nigeria is not a major contributor to global warming, it is really of great concern to the nation since African countries have been identified as the most vulnerable. Combating climate change is a global effort and, as such, all countries must work together to reduce their GHG emission and learn how to cope with the impact. It requires mechanism cutting across government sectoral form of organizations; it involves coordination among multiple sectors; and it requires technical support to strengthen institutional responsibility and additional research to address gap in knowledge.
