Singapore Braces for More Extreme Weather as Climate Change Study Predicts Hotter Days and Rising Sea Levels

Government agencies plan ahead to mitigate potential effects, with implications for health, infrastructure, and food supplies.

Singapore's third National Climate Change Study predicts more frequent very hot days, more extreme daily rainfall as well as longer and more frequent dry spells by the end of the century under a worst-case climate change scenario.
Under the high emissions scenario, the number of days where daily maximum temperatures exceed 35 degrees Celsius could increase from an average of 21.4 days per year in the past 40 years to 351 days per year by the end of the century.
Mean sea levels are projected to rise by 0.23m to 1.15m by the end of the century under all three scenarios, exceeding previous estimates of 1m by 2100. By 2150, mean sea levels may increase by up to around 2m under the high emissions scenario.
Government agencies, including the Urban Redevelopment Authority, National Parks Board, and national water agency PUB, are planning ahead to mitigate potential effects of global warming, such as reviewing building codes and the structural integrity of infrastructure, and developing adaptation pathways up to a planning horizon of 2m sea level rise.
Beyond the impact on health, rising temperatures could disrupt crop yields and food supplies, leading to a need for more sustainable solutions such as reducing food waste.
