Climate change due to enhanced greenhouse effect arising as a result of human activities is considered a major global environmental threat to mankind. This study experimentally investigates and determines the heat flow in and out of the earth surface, and the impact of greenhouse effect on the heat transfer. A high voltage electric bulb was placed between two bottles; an empty bottle containing only air and the other bottle containing a mixture of baking soda and vinegar, evolving CO2. We observed that the vinegar and baking soda in the filled bottle reacted and produced carbon dioxide (CO2). This CO2 absorbs and retains more heat from the high voltage bulb than the empty bottle of normal air. We also observed that visible light passes through the glass and is absorbed by darker surfaces inside. The demonstration of this study proves that greenhouse gases like CO2 is one of major greenhouse gases that are responsible for global warming by trapping heat thereby giving a rapid rise in temperature over time because of the concomitant lower heat loss to its environment.
