Answer
The greenhouse effect is caused by the production of gases such as carbon dioxide and water vapor during the combustion of diesel oil. These gases absorb infrared radiation emitted from the Earth's surface, preventing it from escaping into space. This re-radiation of heat back into the atmosphere contributes to the warming of the planet, a phenomenon known as the greenhouse effect.
