Study from Singapore projects global sea levels could rise by 1.9 meters by 2100

A new study from Singapore's Nanyang Technological University projects global sea levels could rise by up to 1.9 meters by 2100, significantly higher than the United Nations' estimate of 1.01 meters. This study combines existing models with expert opinions to improve accuracy. The researchers developed a method that accounts for uncertainties in current projections, particularly regarding ice sheet behavior. Their findings suggest that under low emissions, sea levels may rise between 0.3 and 1 meter, compared to the IPCC's previous range of 0.32 to 0.62 meters. The study highlights the potential for extreme sea level rise, which could impact coastal communities. Researchers are now working on regional projections, including for Singapore, to better assess local risks.
