The spatial variability of atmospheric carbon dioxide (CO2), carbon monoxide (CO), air temperature and relative humidity in Akure metropolitan city, Ondo State, Nigeria was carried out with the aim to determine how the earth systems are impacted by climatic changes. The objectives are to evaluate the relationships between the climate parameters. Four observational sites (A, B, C and D) were chosen within the area of investigation, which is the Federal University of Technology Akure (FUTA), Nigeria. The HANNA instrument was used to measure CO2 and CO emissions with the corresponding air temperature and relative humidity from the four locations. The interplay between CO levels, temperature, and humidity can have complex effects on local and regional climates. Persistent high levels of CO can lead to deteriorating air quality and health issues, as well as contribute to the warming of the atmosphere. There is a weak negative correlation between CO emissions and time (days) (correlation coefficient of -0.139). This suggests CO emissions may be slightly lower over time. There is a very weak positive correlation between CO2 emissions and time (days) (correlation coefficient of 0.005), which is close to zero and suggests no relationship. There is a moderate positive correlation between air temperature and relative humidity (correlation coefficient of 0.779). This means that as relative humidity increases, air temperature also tends to increase. There is a weak positive correlation between CO emissions and CO2 emissions (correlation coefficient of 0.204) and a weak negative correlation between CO emissions and air temperature (correlation coefficient of -0.111). It is therefore recommended to incorporate sustainable transportation system, adopt sustainable agriculture and forest management, and building sustainable infrastructure to reduce the CO2 emissions from buildings and building new low energy physical structures. Also, adopting renewable energies such as solar, wind, biomass and geothermal, that is, moving away from fossil fuels.
