Impact of Glacial Melting

The video discusses the climate crisis, focusing on sea level rise due to global warming. It explains how rising temperatures cause ocean expansion and ice melting, leading to increased sea levels. The video highlights the formation and melting of glaciers, the impact of melting ice sheets, and regional variations in sea level rise. It also covers the consequences of rising sea levels, such as flooding and habitat loss, and emphasizes the need for adaptation and reducing greenhouse gas emissions.
