This paper assessed the influence of Nigerian media on public knowledge of climate change. This work acknowledges that public understanding of climate change is a prerequisite to taking voluntary action to mitigate its effects. The work therefore sought to ascertain the specific ways in which Nigerian media reportage of climate change had influenced public knowledge of the subject matter. A survey was conducted in Abuja, Enugu, Ikeja and Port Harcourt. Editors of four newspapers in Nigeria were interviewed. Results indicated that the mass media did not rank the highest as sources of information for the audience on climate change, and they (media) did not significantly influence public knowledge of climate change. This finding differed from results of studies in the US. Respondents linked climate change to changes in weather patterns. This study recommended that opinion polls are necessary to see where audience interests lies as well as how much media views influence public understanding in terms of communication effectiveness.
