About the lecture

In this module, we think about past sea level change and how it has impacted coasts over time. We focus on: (i) how the position of the British coastline has moved further inland due to sea level rise over the past 18,000 years; (ii) deglaciation at the end of the last Ice Age as the main cause of this historic sea level rise; (iii) the impacts on coasts of projected future sea level rise linked to human-driven global warming; (iv) the role of Milankovitch cycles in driving past periods of climate change, including that which ended that last Ice Age; (v) the difference between eustatic and isostatic sea level change, and how isostatic uplift has influenced the present position and features of different parts of the British coastline.
