I watched Prime Minister Lee Hsien Loong’s National Day Rally speech on Sunday (Aug 18) night. It was the single most impressive talk about the threat of sea-level rise by a political leader.
In particular, Mr Lee balanced talk of urgency with hopeful and creative ideas to inspire positive change. Mr Lee made it clear that climate change is a matter of life and death for Singapore.
Having studied the issue for 25 years, I am also very worried about sea-level rise and strongly believe that we must urgently act on it. I am the only scientist in Singapore to be part of the United Nation’s Intergovernmental Panel on Climate Change (IPCC) working group that produced a report on the physical science of climate change.
There is a phrase “if you knew what I knew”. Mr Lee noted that the UN has projected that sea levels will rise by 1m by the end of this century but that scientists’ estimates have been going up and sea levels may rise higher and faster than that.
I would say that we should be careful about underestimating the risk. Published peer reviewed studies by myself and other members of the IPCC suggest there is a one in 20 chance sea-level rise in Singapore could be in excess of 2.5m by 2100.
