Why does sea level change? Everyone knows that sea level rise is a threat to coastal cities, but the mechanisms of why the change happens are less often talked about. In my talk I will explain why sea level is changing, why it is changing at different rates around the globe, how we can use the measured sea level rise to find out which ice sheets are melting and how we can make predictions for a warmer world. A lot of the answers to these questions lie in the past: Climate varies over thousands of years and therefore we need to dive into the past if we want to understand the present and predict the future. I will take you on a journey through the climatic past, to times when big ice sheets covered the Earth during the last ice age and beyond.
