In early January this year, the Singapore Center for Climate Research (CCRS) released a new report, called V3, which forecasts several climate scenarios based on findings from international climate change research. family.
According to CCRS, compared to V2 (published in 2015), V3 is based on expanded and updated datasets, so the latest report will provide more accurate scenarios of Singapore’s climate situation. and in Southeast Asia.

Extreme weather becomes normal
According to V3 forecasts, extreme weather events will increase by the end of the 21st century. These phenomena include sea level rise, an increase in average daily temperature, and the number of hot days above 35 degrees Celsius. , evening temperature and average precipitation.
In the worst scenario, by 2100, Singapore will only have about 14 days with an average temperature below 35 degrees Celsius.
The situation is not very positive in the near future. It is predicted that by the middle of the 21st century, Singapore is likely to record from 47 to 189 “very hot” days a year, double the current rate.
By 2050, average daily temperatures could also increase by 0.6 – 2.2 degrees Celsius, depending on whether the world can cut emissions or continue to burn more fossil fuels. This can cause the average temperature during this period to fluctuate around 28.5 degrees Celsius – 30.1 degrees Celsius, up from the current 27.9 degrees Celsius.
Research predicts that by the end of the century, average daily temperatures will increase from about 0.6 – 5 degrees Celsius. This means that by 2100, Singapore’s average temperature will be at 28.5 – 32 degrees Celsius. .9 degrees Celsius.
Besides, the dry season will become drier while rainfall will continue to increase in the rainy season. For example, in the months of April – May, rainfall can increase by 6 – 92%. Meanwhile, in drier months such as June, July and August, rainfall will fall below the historic low of 314 mm recorded in 1997 with a frequency of every 3 years.
Average sea levels could also rise between 0.23 m and 1.15 m by 2100 and up to about 2 m by 2150, depending on whether and how much the world can reduce carbon emissions. How much to cut?

The V3 report is considered to provide a more specific view of climate issues in Singapore and Southeast Asia in the near future, based on data from global models and predictions of temperature and precipitation. , wind speed and sea level.
In particular, climate change forecasts, made by the Intergovernmental Panel on Climate Change (IPCC), often give a more comprehensive view of global and large-scale climate change. These projections lack the detailed data needed to assess climate change at the regional and local levels to help countries plan for action.
To close this gap, the V3 study scaled down a select group of global climate models from IPCC reports to a focused region to produce more detailed and specific predictions.
