The Greenhouse Effect

Mr. Andersen explains the greenhouse effect, its necessity for life on Earth, and how it works by retaining heat. He describes the composition of the atmosphere and the role of greenhouse gases like carbon dioxide and methane. Using a simulation, he demonstrates how these gases interact with light. Historical data from ice cores show past greenhouse gas levels, while modern increases due to industrialization are linked to climate change. The video emphasizes the importance of understanding and managing the greenhouse effect.
