Some important issues to do with long-term sea level change

This paper gives all overview of several important issues concerned with the measurement and understanding of long-term sea level change, which is one of the most important topics in sea level science. The issues discussed span science., technology and our ability to fund and operate the national and global observation networks required for a proper understanding of long-term change and its impacts. Many of these topics were explored at a 'Celebration of UK sea level science' at the Royal Society on 1.6-17 February 2004, and are discussed further in a number of papers in this volume.
