Hydrogen fuel cell heavy-duty trucks offer a cleaner alternative to diesel transport, but public support is essential for large-scale adoption. In a new study, researchers surveyed households in South Korea to measure willingness to pay for expanding hydrogen truck deployment. The results show strong public acceptance, with benefits exceeding carbon reduction costs, indicating the policy is socially profitable and supports long-term low-carbon transport transitions under national climate policy goals frameworks.

A decade-long study led by Penguin Watch¹, at the University of Oxford and Oxford Brookes University, has uncovered a record shift in the breeding season of Antarctic penguins, likely in response to climate change. These changes threaten to disrupt penguins’ access to food and increase interspecies competition. The results have been published today (20 January - World Penguin Awareness Day) in the Journal of Animal Ecology.

Researchers at the School of Engineering of The Hong Kong University of Science and Technology (HKUST) have developed the world’s first Sub-Zero Celsius elastocaloric freezing device, capable of reaching temperatures as low as -12℃. This represents a significant milestone in expanding green solid-state elastocaloric refrigeration technology into the global freezing industry, offering a promising solution to combat climate change and accelerate low-carbon transformation of the global freezing market. The findings have recently been published in the international journal Nature, under the title “Sub-zero Celsius Elastocaloric Cooling via Low-transition-temperature Alloys”.

A new study led by researchers at the University of Oxford has shown that the shape and orientation of coastlines significantly influenced extinction patterns for animals living in the shallow oceans during the last 540 million years. In particular, animals living on convoluted or east-west orientated coastlines (such as those found in the Mediterranean and Gulf of Mexico today) were more likely to go extinct than those living on north-south orientated coastlines.

The findings, published today in Science, provide new insight towards understanding patterns of biodiversity distribution throughout Earth history to the present day, and highlight which modern species may be more at risk of extinction due to climate change.
