Carbon dioxide (CO2) is one of the major greenhouse gases causing global warming. If the carbon dioxide could be converted into energy, it would be killing two birds with one stone in addressing the environmental issues. A joint research team led by City University of Hong Kong (CityU) has developed a new photocatalyst which can produce methane fuel (CH4) selectively and effectively from carbon dioxide using sunlight. According to their research, the quantity of methane produced was almost doubled in the first 8 hours of the reaction process.

Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions.

Researchers in Japan, the US and China say they have found more concrete evidence of the volcanic cause of the largest mass extinction of life. Their research looked at two discrete eruption events: one that was previously unknown to researchers, and the other that resulted in large swaths of terrestrial and marine life going extinct.

Far too little is known about the long-term dynamics of the abundance of most macro-organism species. We used sedimentary DNA technology to quantify marine fish DNA abundance in sediment sequences spanning the last 300 years. This study first shows the existence of fish DNA in the sequences and proves that fish abundance can be tracked using sedimentary DNA, highlighting the utility of sedimentary DNA for researchers to acquire lengthy records of macro-organism species abundance.

Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, develop a novel “heterostructured” photocatalyst using titanium and copper, two abundant and relatively inexpensive metals. Their cost-effective synthesis procedure, coupled with the high stability of the photocatalyst, provides an economically feasible way to convert waste carbon dioxide and water into useful hydrocarbon fuels using endless sunlight.

Hong Kong has been experiencing hotter summers and more scorcher days in recent years due to climate change and heat island effect. Amid the increasing number of “hot nights”, it is found that consecutive “hot nights” are more detrimental to human health than “very hot days”, although the actual temperature does not reach the level of daytime, according to a collaborative research conducted by the Institute of Future Cities at The Chinese University of Hong Kong (CUHK), as well as researchers from the University of Hong Kong. The research also identified that lack of urban greenery and poor air ventilation in a high-density context are factors that lead to more “hot nights” than “hot days” in some areas. The team suggests that better urban planning and building design are long-term mitigation measures.

An international collaborative study led by Professor Derrick Yuk Fo Lai at The Chinese University of Hong Kong (CUHK), joined by top-tier scientists from around the world, has discovered that sustained methane emissions from the subtropical estuarine mangroves can reduce its climatic cooling effects by over 50%, over a period of 20 years. The team produced the world’s first-ever multi-year dataset of ecosystem-scale methane emissions from a subtropical estuarine mangrove based on the data collected at Mai Po Nature Reserve in Hong Kong, which points out that global warming and greater river runoff may lead to increasing methane emissions. The findings have recently been published in Global Change Biology, a top-tier journal in the field of biodiversity conservation and environmental science.
