According to one of Stephan Lewandowsky's colleagues at the Cabot Institute, more than 80% of the Maldives lie below sea level.
Although ~30 to 100 cm of sea level rise may seem insignificant, it is worth considering what this means for other regions. For example, more than 80% of the Maldives lie one metre below sea level. In this region, sea level rise has the potential to impact up to 360,000 citizens and lead to widespread migration.
I would suggest that the author, Dr Gordon Inglis, has got a bit confused here, particularly as his source says something rather different.
