SINGAPORE (Reuters) - Protecting Singapore against rising sea levels could cost S$100 billion (59.3 billion pounds) or more over 100 years, its prime minister said on Sunday, as the low-lying island-state makes preparations to mitigate the impact of global warming.

"How much will it cost to protect ourselves against rising sea levels? My guess is probably S$100 billion over 100 years, quite possibly more," Prime Minister Lee Hsien Loong said.
