Summary: This study enhances the validity of statistical downscaling by considering climate change and air pollution changes. The results show that ground-level ozone concentrations are projected to decrease under the moderate scenario of SSP2-4.5, while increasing concentrations are assessed under the more pessimistic scenario of SSP3-7.0, especially towards the end of the 21st century.

Summary: Wildfires and meteorological conditions have a significant impact on the co-occurrence of PM2.5 and ground-level ozone in the western US. The frequency and intensity of these co-occurrences have increased over the past two decades, leading to an increase in population exposure to harmful air pollutants. The extent of co-occurrence is linked to atmospheric ridging patterns and the extent of extreme heat and wildfires.

Summary: This study assessed ozone exposure and uptake in forests along the Eastern Adriatic coast in the Mediterranean region. Results showed that ozone levels were close to reaching the upper limits for passive monitoring at forest sites, with the highest uptake metrics found in P. nigra. Relationships between environmental variables and forest-health indicators were also analyzed, with significant correlations found between crown defoliation and soil water content, and between tree growth and different O-3 metrics.

Summary: This study used machine learning to predict O3 concentrations and analyze the impact of various factors on O3 formation. The results showed that deep neural network and long short-term memory models could accurately predict O3 concentrations. Variable importance analysis revealed the significant positive contribution of solar radiation to O3, while nitrogen oxides and volatile organic compounds negatively influenced O3 concentrations. The study also found that an increase in water vapor content could offset the effects of raised temperature, and controlling anthropogenic gases, especially carbon monoxide, would play a crucial role in controlling O3 in the future.

Summary: Ozone pollution in urban areas of mainland China has worsened despite the decrease in other air pollutants. Recent studies have enriched our understanding of ozone-related processes and impacts. This article synthesizes the key findings from over 500 articles published in English-language journals in the past six years, focusing on changes in ozone concentrations, drivers, responses during the COVID-19 lockdowns, emerging chemical processes, impacts on crops and trees, and government interventions.

Summary: The winter of 2019/2020 in the Arctic stratosphere had the lowest observed ozone mixing ratios and was characterized by an unusually strong and long-lasting polar vortex. Some aspects of this winter resemble both Antarctic and Arctic conditions, such as the chemical processes and chlorine activation reactions. If the air masses had spent slightly more time below the upper temperature limit for polar stratospheric cloud formation and in sunlight, ozone levels in parts of the vortex could have been reduced to near zero values.

Summary: The accelerating sea level rise in Virginia poses significant threats to low-lying areas, including flooding, saltwater intrusion, and impacts on septic systems. While most adaptation efforts have focused on urban areas, rural regions face different challenges and require prioritization of data collection for effective adaptation measures.

Summary: Many African heritage sites are currently at risk from rising sea levels, which could more than triple under high emissions scenarios. Mitigating emissions can reduce the number of highly exposed sites. These findings highlight the urgent need for increased climate change adaptation for heritage sites in Africa, including governance, vulnerability assessments, monitoring, and protection strategies.

Summary: The disorderly growth of metropolitan regions combined with inadequate air quality management strategies may lead to an increase in O3 levels, impacting living organisms negatively. The study identified significant excess of O-3 concentrations in the expanded region of the Rio de Janeiro Metropolitan Area, highlighting the need for improved monitoring and management practices.

Summary: This study investigates the cooccurrences of heat and air pollution extremes in China. The results show a significant increase in the frequency of joint exceedances of wet-bulb temperature (w) and O-3, mainly in the Beijing-Tianjin-Hebei region and the Yangtze River delta. Moreover, the rate of joint exceedance is higher than the rate of T-w and O-3 themselves.

Summary: This study examines the impact of anthropogenic emissions on premature deaths caused by transboundary ozone in country groups categorized by income level. The findings show that mortality rates have increased 27 times from 1951 to 2019. The study also reveals an inverted U-shaped relationship between affluence and per-million-people contribution to mortality caused by transboundary ozone in high-income and upper middle-income groups.

Summary: This study investigates the variation of suction, moisture content and temperature in soil under changing climatic conditions, using a numerical model. The predictions indicate that there will be an increase in suction and ground temperature, while soil moisture content decreases in the future. It is recommended that soil characteristics and depth to water table should be considered when estimating ground suction.
