Answer
The complete combustion of diesel oil produces carbon dioxide (CO₂) and water (H₂O).
Carbon dioxide is a greenhouse gas, which means it traps heat in the atmosphere.
As more fossil fuels are burned, the concentration of CO₂ in the atmosphere increases, enhancing the greenhouse effect, leading to global warming and climate change.
