The need to study the variations of climate change in Nigeria becomes necessary at a time the universe and Nigerians, in particular are passing through challenges due to climate change as a result of emissions. The atmospheric gases have a greater transparency for incoming solar radiation, while the outgoing are trapped and re-emitted back to the Earth. This study correlated between global solar radiation and greenhouse gases over Nigeria using neural network. The results showed that positive correlations exist between solar radiations: CO2 and CH4 respectively, while exhibiting negative correlations with tropospheric ozone and water vapour. Consequently, an increase in 0.1017, 0.1350 units of CO2 and CH4, respectively could enhance the trapping and transmission of solar radiation in the atmosphere, while an increase of 1.1234 and 0.1530 units of tropospheric ozone and water vapour could cause absorption of solar radiation. The trapped energy is re-radiated back to the Earth, this warms up the atmosphere and the surface of the Earth resulting to global warming. Coefficient of determination revealed that 18%, 30%, 20%, and 29%, of the variances of solar radiation being studied is explained by the variance of the water vapour, tropospheric O3, CO2, and CH4, respectively.

This paper examines the impact of aliteracy on learning English as a second language in Nigeria. Genuine concern expressed by stakeholders on the poor performance exhibited by Nigerian secondary school students in English language has led to a number of inquiries for solutions to the problem. Many studies have attributed poor language performance to a number of factors but nobody has connected the apathetic stance of students towards reading to poor language performance. Their appalling performance manifests in the plethora of spelling and grammatical errors that riddle essay assignments. Writing is a productive language skill by which a student demonstrates his ability to produce grammatically correct and connected texts. This study searches for the link between students’ lack of interest in reading and their writing competence. Aliteracy is the state of being able to read but being uninterested in doing so. The data for the study were generated from students’ written essay and questionnaire. An analysis of the students’ reading habits juxtaposed with their continuous writing showed that students who were avid readers performed better than those who did not like to read. This result shows that the decline in the level and quality of language written by senior secondary school students in Nigeria can be attributed to poor reading culture.
