BackgroundPaediatric asthma incidence is associated with exposure to traffic-related air pollution (TRAP), but the TRAP-attributable burden remains poorly quantified. Nitrogen dioxide (NO2) a major component and common proxy of TRAP. In this study, we estimated annual global number new paediatric cases attributable NO2 at resolution sufficient resolve intra-urban gradients.MethodsWe obtained 2015 country-specific age-group-specific rates from Institute for Health Metrics Evaluation 194...
The mitigation scenarios database of the Intergovernmental Panel on Climate Change's Sixth Assessment Report is an important resource for informing policymaking energy transitions. However, there a large variety models, scenario designs, and resulting outputs. Here we analyse consistent with limiting warming to 2 °C or below regarding speed, trajectory, feasibility different fossil fuel reduction pathways. In 1.5 no limited overshoot, global coal, oil, natural gas supply (intended all uses)...
Abstract Emissions from the transportation sector are a major contributor to ambient air pollution, leading environmental health risk factor globally. This study aims quantify contribution of tailpipe emissions global transportation, disaggregated by four sub-sectors, disease burden associated with fine particulate matter (PM 2.5 ) and ground-level ozone in 2010 2015. We use GEOS-Chem chemical transport model simulate transportation-attributable PM concentrations, combined epidemiological...
Abstract Urban air pollution is high on global health and sustainability agendas, but information limited associated city-level disease burdens. We estimated fine particulate matter (PM 2.5 ) mortality in the 250 most populous cities worldwide using PM concentrations, population, rates, concentration-response relationships from Global Burden of Disease 2016 Study. Only 8% these had population-weighted mean concentrations below World Health Organization guideline for annual average ....
We investigate the present-day sensitivity of fine dust levels in US Southwest to regional drought conditions and use observed relationships assess future changes associated health impacts under climate change. Empirical Orthogonal Function analysis reveals that most dominant mode interannual variability for each season consists a pattern large-scale co-variability across Southwest. This is strongly correlated Standardized Precipitation-Evapotranspiration Index (SPEI) accumulated over 1–6...
The U.S. Southwest is projected to experience increasing aridity due climate change. We quantify the resulting impacts on ambient dust levels and public health using methods consistent with Environmental Protection Agency's Climate Change Impacts Risk Analysis framework. first demonstrate that fine (PM2.5) coarse (PM2.5-10) are strongly sensitive variability in 2-month Standardized Precipitation-Evapotranspiration Index across southwestern North America. then estimate potential changes...
Abstract We use empirical orthogonal function (EOF) analysis to investigate the role of meteorology in controlling interannual variability fine dust concentrations western United States during 2002–2015 March–May. then develop a prediction model explore causes an observed increase March Southwest. For each spring month, 54–61% total variance anomalies can be explained by first two leading EOF modes, which consist coherent pattern covariability across West and dipole northwest‐southwest...
Abstract Non-technical summary We identify a set of essential recent advances in climate change research with high policy relevance, across natural and social sciences: (1) looming inevitability implications overshooting the 1.5°C warming limit, (2) urgent need for rapid managed fossil fuel phase-out, (3) challenges scaling carbon dioxide removal, (4) uncertainties regarding future contribution sinks, (5) intertwinedness crises biodiversity loss change, (6) compound events, (7) mountain...
Abstract. Many important atmospheric aerosol processes depend on the chemical composition of aerosol, e.g. water uptake and particle cloud interactions. Atmospheric ageing processes, such as oxidation reactions, significantly continuously change particles throughout their lifetime. These are often poorly understood. In this study we utilize an flow tube set up ultra-high resolution mass spectrometer to explore effect relative humidity (RH) in range <5–90% ozonolysis maleic acid which is...
Abstract The world’s large and growing appetite for meat other animal products has profound implications One Health, given its impacts on human health, the environment health welfare. Accordingly, there is robust evidence that a reduction of product consumption urgently needed in regions where these levels are currently high. A shift away from industrial production should be prioritized, high this kind system enables, relatively environmental toll, linkages to increasing risks antimicrobial...
Abstract. Isoprene and its oxidation products are major players in the oxidative chemistry of troposphere. Current understanding factors controlling biogenic isoprene emissions fate atmosphere has been evolving rapidly. We use a climate–biosphere–chemistry modeling framework to evaluate sensitivity estimates tropospheric capacity uncertainties photochemistry. Our work focuses on two climate transitions: from Last Glacial Maximum (LGM, 19 000–23 000 years BP) preindustrial (1770s) present day...
The influence of oil and gas end-use activities on ambient air quality is complex understudied, particularly in regions where intensive large biogenic emissions isoprene coincide. In these regions, vehicular nitrogen oxides (NOx≡NO + NO2) modulate the oxidative fate isoprene, a precursor harmful pollutants ozone, formaldehyde, particulate matter (PM2.5). Here, we investigate direct indirect quality. To do so, use GEOS-Chem model with focus eastern United States (US) summer. Regional mean NOx...
Abstract Nitrogen dioxide (NO 2 ) is a major urban air pollutant and associated with new onset asthma among children worldwide. Since NO concentrations are spatially heterogeneous correlated population, the spatial resolution of concentration estimates disease burden calculations could strongly influence magnitude distribution estimated -attributable pediatric (PA) cases. Here, we investigate effect exposure population data on attributable PA incidence. We use epidemiologically derived...
Abstract The United States has supported the development of its oil and gas industry since early twentieth century. Despite repeated pledges to phase out ‘inefficient’ fossil fuel subsidies, US production continues be subsidized by billions dollars each year. In this study, we quantify how 16 subsidies regulatory exemptions individually altogether affect economics in 2020–2030 under different price financial risk outlooks. We find that, at 2019 average market prices gas, could increase rates...
Abstract. Current understanding of the factors controlling biogenic isoprene emissions and fate oxidation products in atmosphere has been evolving rapidly. We use a climate-biosphere-chemistry modeling framework to evaluate sensitivity estimates tropospheric oxidative capacity uncertainties photochemistry. Our work focuses on trends across two time horizons: from Last Glacial Maximum (LGM, 21 000 years BP) preindustrial (1770s); present day (1990s). find that different oxidants have...
Oil and gas account for more than two-thirds of energy consumed in the US. The high-temperature combustion from this use yields large quantities nitrogen oxides (NOx) that modulate oxidative fate isoprene, a precursor health-hazardous air pollutants ozone, formaldehyde, fine particulate matter (PM2.5). COVID-19 pandemic resulting lockdowns provided unique opportunity to examine changes ozone PM2.5 linked dramatic reduction vehicle emissions. These occurred mostly early spring when...
