Tick-tock, tick-tock: the climate clock is making an alarming sound, counting down the amount of time we have left to save the earth. Scorching heat and potentially devastating flooding are both on the rise. Two recent CUHK studies have explored what we can do about that: while one is helping the authorities map floods and take contingency measures, the other predicts an ever hotter future, and suggests ways we can mitigate the heat’s most debilitating effects.

A CUHK professor is trying to turn Geographical Information Science into a vehicle for improving people's lives. From helping protect the vulnerable groups who are most at risk of COVID-19 to monitoring the safety of public infrastructure, her work shows how the field can be a force for good.
