SMU Associate Professor of Science, Technology and Society Winston Chow weighed in with his observations on why weather in June is cooler and wetter in a 10-part Twitter thread. He clarified that Meteorological Service Singapore had compared the record of rainfall in June over a span of 10 years' data, which is insufficient to conclude that this is a sign of climate change. Assoc Prof Chow plotted out the rainfall trend over 40 years from 1980 to 2020 and noted that it does not show that the June 2020 rainfall is "extraordinary". He concluded that while not all extreme weathers are a sign of climate change, there is a "strong climate change" signal from the rising temperatures in the long-term record.
