SINGAPORE - Sea levels in Singapore could increase by 1.37m by 2150, in a scenario where a large amount of greenhouse gas emissions leads to global warming exceeding 4 deg C by the end of the century, a new study has found.
The results hold scientific significance for better adaptation and mitigation measures, as scientists and policymakers can gain a more comprehensive understanding of the long-term impacts of climate change and rising sea levels for Singapore, said the Meteorological Service Singapore , a unit under the National Environment Agency, and national water agency PUB.
So far, the world has already warmed by almost 1.2 deg C, and humanity must keep global warming to 1.5 deg C to avert the more catastrophic impacts of climate change. The study, which was led by the observatory’s senior research fellow Timothy Shaw, found that projected changes in future sea levels will occur over timescales significantly faster than they have in the past.
“But today, we are witnessing much more rapid changes as temperatures rise in response to anthropogenic factors,” the paper noted.The study was published in June in the scientific journal Communications Earth & Environment. Dr Shaw noted that the projected rates of sea-level change under moderate to high emissions scenarios could also make it difficult for coastal ecosystems such as mangroves to survive. Mangroves buffer the coastline from major storm events and sea-level rise.
