The video explains the natural greenhouse effect, showing how the atmosphere retains heat from the sun, keeping Earth warm. It describes the role of gravity in holding gases, the electromagnetic spectrum, and how greenhouse gases like water vapor and carbon dioxide trap heat. Before industrialization, carbon dioxide levels were low but sufficient to maintain warmth. The video concludes with a summary and a preview of how fossil fuels contribute to climate change.
