Commenting on Singapore experiencing its hottest May day on record earlier this month, SMU Associate Professor of Science, Technology and Society Winston Chow said, "The warmer-than-normal temperatures we’ve been seeing are expected as climate change generally increases global temperatures over the past 40 years." He added that there is a strong urban heat island effect from Singapore’s built-up areas, which stores heat during the day and releases it at night.
