Abstract
The Maldive Islands are often used as case studies within research into the impacts of potential future sea level change. Therefore, if such studies are to be realistic, it is important that the past and future variations of sea level in the islands are understood as well as possible. That objective led a fieldwork team to the Maldives, and resulted in a conclusion that sea level in the islands fell by approximately 30 cm during the past few decades. In the present paper, the suggestion of such a fall has been examined from meteorological and oceanographic perspectives and found to be implausible. A number of met-ocean data sets and regional climate indices have been examined, at least one of which would have been expected to reflect a large sea level fall, without any supporting evidence being found. In particular, a suggestion that an increase in evaporation could have caused the fall has been demonstrated to be incorrect. Without any real evidence for a hitherto-unrecognised process which could lead to a sea level change as significant as that proposed by the fieldwork team, one concludes that a rise in sea level of approximately half a metre during the 21st century, as suggested by the Intergovernmental Panel on Climate Change Third Assessment Report, remains the most reliable scenario to employ in future studies of the islands.
