Summary: From December 14th to 17th, 2013, the Pearl River Delta in South China experienced the largest winter precipitation in 4 days, with more than 100 mm, since 1998, due to strong cold air intrusion. Through Weather Research and Forecasting (WRF) model simulations, it was found that human activities can contribute to the increase in extreme rainfall in this region. The study highlights the importance of both thermodynamic and dynamic forcing in intensifying the extreme rainfall event.

Summary: Coastal morphodynamics and environmental changes are significantly influenced by global warming, sea-level fluctuations, and human activities. Palynological analysis provides important information on vegetation, climate, and environmental change during the Holocene. Detailed analyses from the Pearl River Estuary show marine transgressive processes, vegetation distribution, and climate variations during different stages of the Holocene.

Summary: The central government of China aims to transform the Pearl River Delta (PRD) from a polluting and low value-added global factory to a sustainable region, underpinned by the ecological civilization concept. However, China's top-down and command-and-control mode of environmental governance may not address the multi-dimensional and multi-scalar social and environmental justice issues of the PRD cities. The authors suggest embracing environmental justice, which requires institutional changes and legislative adjustments to recognize individual environmental rights and incorporate public participation.

Summary: This study highlights the impact of socio-economic status on the distribution of dengue fever, with SES and gender ratio identified as key factors influencing dengue incidence. It found that cases are more likely to occur in poorer neighborhoods, and the effect of SES is partly mediated by population density and the presence of migrant groups.

Summary: This study investigates the dynamics of environmental pollution in the Pearl River Delta region and the influences of different economic drivers. The results indicate that economic transformation has deeply shaped the pollution patterns, with significant changes in the contribution share of international exports and local demand. Reducing emission intensity remains the most effective way to alleviate pollution, and optimizing production structure and consumption patterns will play a more important role in future emission mitigation efforts.

Summary: Dengue has become a serious health concern in China with increased incidence and expanded outbreak regions. Imported cases occur year-round, mainly introduced from Southeast Asia. Dengue outbreaks occur almost every year in high-risk areas such as Yunnan, Guangdong, and Fujian provinces, with seven genotypes of DENV 1-3 detected. The genetic relationships among viral strains suggest that indigenous viruses in high-risk areas in China arose from imported viruses and sometimes persisted between years, especially in Guangdong Province.

Summary: This study proposes a real-time saltwater intrusion early warning framework based on timeseries clustering to improve the accuracy and lead time of predictions. By clustering previous observations, a comprehensive 24-h forecast of saltwater intrusion risk is obtained. The latest supervised clustering model, CAMELOT, outperforms traditional unsupervised clustering models and machine learning classifiers. The analysis reveals that the variation in saltwater intrusion length is strongly associated with tidal cycles and upstream discharge.

Summary: This study estimated organic aerosol emissions from cooking during winter in the Pearl River Delta region, China. Results showed that cooking contributes significantly to OA concentrations in urban areas, with different patterns observed between weekdays and weekends. Considering COA emissions in the model increased regional OA concentrations by 4.6% and 7.4% for different scenarios.

Summary: Low socioeconomic status, high temperature, and increasing rainfall patterns are associated with increased dengue case counts. This study investigated the impact of poverty and climatic variables on the distribution of dengue virus serotypes and the rate of severe dengue in Mexico. Results showed that increased poverty and climatic variables led to higher rates of DENV-1, DENV-2, DENV-3, and DENV-4. Hotspots of all DENV serotypes and severe dengue were observed in certain regions of Mexico. These findings can inform policies to allocate public health resources effectively in vulnerable municipalities.

Summary: Cross-regional transport contributes significantly to PM2.5 nitrate (pNO3) in the Pearl River Delta (PRD), with 58% of pNO3 monthly contributed by indirect transport, mainly involving transported O-3 and locally emitted NOx reacting to produce pNO3 through N2O5 heterogeneous hydrolysis. The sensitivity of pNO3 contributions to O-3 and NOx emissions varies among cities, showcasing the notable effect and complex process of cross-regional pNO3 transport in the PRD.

Summary: This study aimed to investigate the modifying effect of air pollution on the association between meteorological factors and dengue fever incidence. The study found that the impact of low-temperature, low-precipitation, and wind speed on dengue occurrence tended to increase on days with high SO2 levels, while the impact of high-temperature and high-precipitation decreased.
