In California, wildfire risk and severity have grown substantially in the last several decades. Research has characterized extensive adverse health impacts from exposure to wildfire-attributable fine particulate matter (PM 2.5 ), but few studies quantified long-term outcomes, none used a wildfire-specific chronic dose-response mortality coefficient. Here, we burden for PM California fires 2008 2018 using Community Multiscale Air Quality modeling system wildland fire estimates. We concentration-response function , applying ZIP code–level data an estimated coefficient accounting likely toxicity of smoke. estimate total 52,480 55,710 premature deaths are attributable over 11-year period with respect two scenarios, equating economic impact $432 $456 billion. These findings extend evidence on climate-related impacts, suggesting that wildfires account greater than indicated by earlier studies.

Smoke from wildfires poses a substantial threat to health in communities near and far. To mitigate the extent potential damage of wildfires, prescribed burning techniques are commonly employed as land management tools; however, they introduce their own smoke-related risks. This study investigates impact fires on daily average PM2.5 maximum 8-h averaged O3 (MDA8-O3) concentrations estimates premature deaths associated with short-term exposure fire MDA8-O3 Georgia surrounding areas Southeastern US 2015 2020. Our findings indicate that over domain, contributes by 0.94 ± 1.45 μg/m3 (mean standard deviation), accounting for 14.0% year-round ambient PM2.5. Higher contributions were predicted during extensive season (January–April): 1.43 1.97 (20.0% PM2.5). Additionally, is also responsible an annual increase 0.36 0.61 ppb (approximately 0.8% MDA8-O3) 1.3% (0.62 0.88 ppb) season. We estimate could have caused 2665 (95% confidence interval (CI): 2249–3080) 233 CI: 148–317) excess deaths, respectively. These results suggest smoke burns increases mortality. However, refraining such may escalate risk wildfires; therefore, trade-offs between impacts fires, including morbidity, need be taken into consideration future studies.

Wildfires have become more frequent and severe, evidence showed that exposure to wildfire-caused PM 2.5 (fire-PM ) is associated with adverse health effects. Fire-PM occurs mainly indoors, where people spend most of their time. As an effective timely approach mitigating indoor pollution, air purifiers incur notable costs. However, the long-term global population fire-PM economic burden using remain unknown. Here, we estimated concentration cost reducing exposure, along extra incurred because , at a resolution 0.5° by globally during 2003 2022. Our findings revealed 1009 million individuals exposed least one substantial wildfire-air pollution day per year. We identified pronounced socioeconomic disparities in costs low-income countries bearing disproportionately higher burden, emphasizing critical need for addressing these disparities.

Despite a significant increase in United States biomass energy sector activity, including domestic bioenergy deployment and wood pellet production for overseas exports, the associated criteria pollutant emissions are not well quantified current regulatory inventories. We present an updated U.S. inventory, with emphasis on wood-based pretreatment (e.g., drying, condensing, storage of pellet) use generation. As number facilities included inventories, we find that this sector's could be potentially underestimated by factor two. Emissions from biomass-based average up to 2.8 times higher than their non-biomass counterparts per unit energy. estimate 2.3 million people live within 2 km facility who subject adverse health impacts emissions. Overall, contributes about 3–17% total all energy, i.e., electric non-electric generating also review some drivers expansion, such as various feedstocks technologies deployed discuss implications future air quality impacts.

Abstract New Yorkers face a multitude of health and safety risks that are exacerbated by changing climate. These include direct impacts from extreme weather events other climate hazards, as well indirect occurring through chain interactions. Physical safety, physical health, mental all part the equation—as many nonclimate factors interact with change to influence outcomes. This chapter provides an updated assessment these topics at intersection change, public equity in state York. Key findings presented below.

The 2022 wildfires in New Mexico, United States, were unparalleled compared to past the state both their scale and intensity, resulting poor air quality a catastrophic loss of habitat livelihood. Among all Mexico 2022, six selected for our study based on size burn area proximity populated areas. These fires accounted approximately 90 % total 2022. We used regional chemical transport model data-fusion technique quantify contribution these (April 6 August 22) particulate matter (PM2.5: diameter ≤ 2.5 μm) ozone (O3) concentrations, as well associated health impacts from short-term exposure. estimated that emitted 152 thousand tons PM2.5 287 volatile organic compounds atmosphere. average daily wildfire smoke across was 0.3 μg/m3, though 1 h maximum exceeded 120 μg/m3 near Santa Fe.

Daily fire progression information is crucial for public health studies that examine the relationship between population-level smoke exposures and subsequent events. Issues with remote sensing used in emissions inventories (FEI) lead to possibility of missed impact results acute effects studies. This paper provides a method improving an FEI dataset readily available create more robust daily progression. High temporal spatial resolution burned area from two products are combined into single dataset, linear regression model fills gaps The up 71% PM2.5 emissions, 69% area, 367% days per year than using source information. combination improved no estimates. functional improvement data can be achieved currently data.
