SINGAPORE (Reuters) -- Protecting Singapore against rising sea levels could cost S$100 billion ($72 billion) 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.
