Aside from this, Singapore may also see more intense and frequent rainfall, with global precipitation projected to increase with each additional degree of warming.
Since 1980, the country’s average annual rainfall has increased at an average rate of around 70mm per decade. The intensity and frequency of heavy rainfall events have also increased over the past few decades up until 2012, but these trends were modulated by strong El Nino conditions in 2015 to 2016, the press release said.
While it is challenging to pinpoint the cause of past rainfall changes in Singapore with current models due to a combination of factors, MSS said it will continue to study this, along with the impact of climate change on the country’s weather.
RISING SEA LEVELS
Another area of concern for low-lying countries like Singapore is rising sea levels.
The report warned that under a low emission scenario, global mean sea levels could rise between 0.32m and 0.62m by the turn of the century. Under the highest emission scenario, sea levels could rise between 0.63m and 1.01m.
The report also said sea level rise is virtually certain to continue throughout the 21st century in most regions of the world.
While sea level change is not globally uniformed, and regional and local rates of sea level rise may differ from the global mean, MSE and MSS said Singapore will study sea level rise in “greater detail” under a national programme that aims to strengthen local research and provide more robust projections of sea level change for the country and the surrounding region.
Findings from the national sea level programme will be contextualised by the Centre for Climate Research, which will also study their impact on Singapore.
