Greenhouse Gases and Climate Change

Mr. Andersen discusses global climate change, focusing on the causes, such as solar radiation and greenhouse gases, and the rapid changes currently occurring. He highlights international efforts like the Kyoto Protocol and Paris Agreement to reduce greenhouse gases. The video explains the greenhouse effect and its role in warming the planet, detailing both natural and anthropogenic sources of greenhouse gases. The impacts of climate change on the environment and humans, including rising sea levels and increased natural disasters, are explored. The video concludes with a call for global cooperation to address these challenges.
