Kallang: about 46 years until another tenth of its land sits below the safety line at today's pace (2072). About 20% is below it already and depends on seawalls, tidal gates and drains.
At today's pace of emissions. An area-wide estimate for Kallang planning area, not a reading for any one building.
Coastal: another tenth of the area's land sits below the safety line (3 m above mean sea level plus projected sea-level rise). Heat: 30 or more days a year at or above 35°C. Flash-flood downpours: days with 50 mm or more of rain across Singapore reach 1.5 times their 1995–2014 level; one date for every area, since the rain model can't tell neighbouring areas apart. For local flooding, see PUB's list below. Mortgage and lease are counted from today.
