Research in recent decades has demonstrated that the change of sea level is far from uniform around the globe. Even within a relatively small coastal area like the Netherlands, notable differences are found in the rise of sea level, which are still partly unexplained. We will organise a NCK theme day on this topic on 28 September in Leiden, where we'll bring together researchers from various universities and institutes to provide a comprehensive overview of the state-of-the-art knowledge on regional sea level change and to identify lacunae in our understanding.
