Climate Change Impact and Effects

The lecture discusses human influence on climate change, starting with historical impacts like the Industrial Revolution and deforestation. It highlights current changes such as rising global temperatures and increased greenhouse gases. The potential future effects include sea level rise, changes in vegetation zones, and ecosystem disruptions. The lecture concludes with a preview of solutions to be discussed in the next session.
