ABSTRACT

Generally, it is believed that change in climate is driven by natural and human induced disturbances of the earth energy balance. In Nigeria, the perturbation of the earth energy balance is caused majorly by human induced carbon dioxide. Carbon dioxide is an important heat-trapping greenhouse gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration. The study examined the relative influence of XCO₂ on climate variables and rice yield in Ohafia, Abia State, Nigeria. The instrument used was the Greenhouse Gas Observation Satellite (GOSAT), which uses the Thermal and Near Infrared Sensor for Carbon Observation- Fourier Transform Spectrometer (TANSO-FTS). Transform Spectrometer (FTS) exporter tool was used for scanning XCO₂. Regression model and forecast model were also employed in the study. The results indicated that from 2009 to 2020, XCO₂ increased from 390.98 ppmv to 399.59 ppmv. Maximum temperature moved from 32.51℃ to 33.23℃ and minimum temperature fluxed between 17.38℃ to 14.12℃. Radiation increased from 86.93 to 89.23 W/m² and albedo fluxed around 0.16 to 0.15. Relative humidity decreased from 87.69% to 85.31% and precipitation fluxed between 1,518.75 mm to 1,608.4 mm. Rice yield fluxed between 19306 100g/ha to 26709 100g/ha. The rice yield graph shows that rice yield from 2021 to 2030 is expected to be constant at 19,794.97 100g/ha if XCO₂ continues to increase from 400 to 404.83 ppmv. This means maximum temperature is expected to be constant at 32.59℃ and minimum temperature may decrease from 17.05℃ to 15.88℃. Radiation may increase from 89.59 to 99.3 and albedo is expected to remain at 0.16. Relative humidity is expected to decrease from 85.64% to 84% and precipitation is expected to be constant at 1,781.984 mm. The study therefore recommended that an ambiguous target of 30% reduction of carbon dioxide should be set to reduce the level of carbon dioxide increase in the atmosphere before 2025 or 2030.
