Landslides, flash floods, and fallen trees—these are just some of the alarming sights accompanying the summer typhoon seasons in Hong Kong. Over the past decade, the city has witnessed a distressing surge in extreme rainfall, characterized by intensity levels that surpass the Black Rainstorm Warning Signal. This trend serves as a stark reminder of the growing impact of global warming on our daily lives and safety. The question resonates: how can we better prepare for nature’s fury in the future?

Tropical marine low clouds play a crucial role in regulating Earth’s climate. However, whether they mitigate or exacerbate global warming has long remained a mystery. Now, researchers from the School of Engineering at the Hong Kong University of Science and Technology (HKUST) have developed a groundbreaking method that significantly improves accuracy in climate predictions. This led to a major discovery – that tropical cloud feedback may have amplified the greenhouse effect by a staggering 71% more than previously known to scientists.

Researchers at the Hong Kong University of Science and Technology (HKUST) have developed the world’s first kilowatt-scale elastocaloric cooling device. The device can stabilize indoor temperatures at a comfortable 21-22°C in just 15 minutes, even when outdoor temperatures reach between 30-31°C, marking a significant breakthrough toward the commercial application of elastocaloric solid-state cooling technology.
