Summary: Studies project that climate change will lead to a significant number of excess deaths, with hotter and poorer places being more adversely affected. Without income-based adaptation, global mortality is expected to increase, but the increase is lower when income is considered. The current estimates of climate-change induced excess mortality are likely underestimated in current SCC calculations.

Summary: Wildfire activities in the western U.S. have become more frequent and severe in recent decades, leading to increased smoke PM2.5 emissions. Agricultural workers, due to their outdoor and physically demanding work, are particularly vulnerable to the harmful effects of wildfire smoke pollution. A study conducted in California quantifies the potential exposure of agricultural workers to past and future smoke PM2.5. The findings suggest that future increases in smoke PM2.5 concentrations could pose a significant threat to agricultural regions, with a substantial increase in worker exposure days projected under future climate conditions.

Summary: Due to dependence on fossil fuels, climate change and air pollution have severely impacted human and planetary health. However, climate solutions offer an opportunity to create cleaner, healthier, and safer communities at both local and global levels. This review highlights the health risks of climate change, explores climate and health solutions, and provides a synthesis of social science research on climate and health communication. It demonstrates that messaging strategies emphasizing the health impacts of climate change and the benefits of climate solutions can effectively build public and political support. Additionally, health professionals are trusted sources of information and have expressed interest in engaging with the public and policymakers on the health implications of climate change and clean energy. This review suggests that health students and professionals have the potential to address climate change as a public health imperative by aligning message strategies with the interests of highly trusted messengers.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
