Coastal Flooding and Storm Surges

The video discusses the impact of climate change on coastal flooding, highlighting how rising sea levels and frequent storms increase flood risks, especially in low-lying areas. It covers historical events like the 1953 storm surge, which caused significant damage and loss of life, and the subsequent government response, including the construction of the Thames Barrier. The video also addresses recent flooding events and future predictions, emphasizing the need for improved defenses.
