Preliminary studies indicate that Singapore is safe from rising sea levels.
However, there is no word on where the government commissioned study can be obtained, or how the general public may access the document. This is certainly something I would want to read first-hand.
From this article, it appears the study was done by the Singapore-Delft Water Alliance and the Tropical Marine Sciences Institute. The lead investigator was Dr Leong Shie-Yui. Searches of their websites turned up nothing though.
