Keeping Cities Cool in a Warmer Future

2023 was the world’s hottest year on record, and temperatures are expected to continue heating up. Cities, where more than half of the world lives, are contending with this extreme heat. But some places, such as Singapore, are looking for ways to modify aspects of their cities to make them more comfortable for people to live. The Cooling Singapore project is creating a hyper detailed digital twin of the city-state to be able to test the effectiveness of new methods the city would want to implement. WSJ’s Alex Ossola explains what they’ve learned, and how it can help us understand how more cities in the future might make changes to combat heat.
