ABSTRACT

Since the end of the last Ice Age, some 18 000 years ago, the sea level has risen by over 120 m as the land ice melted and flowed back into the sea. Britain, then, was joined to the continent by its entire eastern coastline. On average, sea levels have risen at a rate of around 0.1–0.2 mm per year over the past 3000 years globally, but in the twentieth century this has increased to 1–2 mm per year in an upward trend.
