Is Singapore likely likely to be submerged due to Global warming?

Question

I read that cities like London would submerge due to rising ocean level as a result of Global warming over the next few decades. What about Singapore, wichis a small island-city nation?

Answer 1

Short answer: No, not for a very long time.

Explanation:

The highest spot in Singapore is 177 metres above sea level, the average elevation is 50 metres above sea level.

Sea levels are currently rising by 3mm a year (global average) and are expected to rise by 5 or 6mm a year by the end of the century. In the worst case scenario thy would rise by 10mm a year.

There are some places where sea levels are rising faster than others, Singapore may be one such place and if so it's possible sea levels may already be rising by 10 to 20 mm a year.

Singapore has the advantage of being a small island and could easily built a defensive wall right around the coastline. This wall would only need to be one metre high, enough to protect the city from rising sea levels for at least 100 years.

It's worth pointing out that the media can rightly be accused of being over dramatic when it comes to rising sea levels. Yes they are rising but it's a slow and gradual rise. Some cities are at risk but only in the long term, many cities can take preventitive measures such as building levees flood barriers. It's the wide open, low-lying areas that are most at risk and already some islands in the Pacific have been lost to rising sea levels (global warming may not be the sole reason, coral dynamiting may have a role to play as well).

Answer 2

Yes singapore is an island but its not a small FLAT atoll like many of the islands of Micronesia and Polynesia.

Depending on how high the waters rise ...if they do ...
I imagine the Singaporeans would build dykes and sea walls, fill in the area behind and just move inland.

Since most modern ships have to berth offshore away the main problem would be water coming up the creeks and the coastal marshes to the north but most of those have been filled in for housing or parks anyway.

The main problem would be the damage to the chinatown heritage buildings which are close to the waterfront.

Fortunately most of the temples and government buildings and much of the housing is on the slopes of the central peak.

Answer 3

I guess Singapore as a whole won't be submerged but rather those flood prone area. Maybe then Singapore would be a cluster of small islands.

Answer 4

yup.
i think singapore will also submerged if global warming get worsen.
