Answer
The complete combustion of diesel oil produces carbon dioxide (CO₂) and water vapor (H₂O), which are greenhouse gases.
When these gases are released into the atmosphere, they trap heat from the sun, preventing it from escaping back into space. This leads to an increase in Earth's temperature, contributing to climate change. Additionally, increased levels of CO₂ in the atmosphere can enhance the greenhouse effect, leading to further warming and associated environmental issues.
