Climate change impacts on projections of excess mortality at 2030 using spatially varying ozone-temperature (JOURNAL)
We project the change in ozone-related mortality burden attributable to changes in climate between a historical (1995-2005) and near-future (2025-2035) time period while incorporating a non-linear and synergistic effect of ozone and temperature on mortality. We simulate air quali...
Community vulnerability to health impacts of wildland fire smoke exposure (JOURNAL)
Identifying communities vulnerable to adverse health effects from exposure to wildfire smoke may help prepare responses, increase the resilience to smoke and improve public health outcomes during smoke days. We developed a Community Health-Vulnerability Index (CHVI) based on fact...
An approach to measure parameter sensitivity in watershed hydrological modelling (JOURNAL)
Hydrologic responses vary spatially and temporally according to watershed characteristics. In this study, the hydrologic models that we developed earlier for the Little Miami River (LMR) and Las Vegas Wash (LVW) watersheds were used for detail sensitivity analyses. To compare the...
Coupling Computer-Aided Process Simulation and Estimations of Emissions and Land Use for Rapid Life Cycle Inventory Modeling (JOURNAL)
A methodology is described for developing a gate-to-gate life cycle inventory (LCI) of a chemical manufacturing process to support the application of life cycle assessment in the design and regulation of sustainable chemicals. The inventories were derived by first applying proces...
Environmental effects of ozone depletion and its interactions with climate change: Progress report, 2016 (JOURNAL)
When considering the effects of climate change, it has become clear that processes resulting in changes in stratospheric ozone are more complex than previously believed. As a result of this, human health and environmental issues will be longer-lasting and more regionally variable...
Projecting state-level air pollutant emissions using an integrated assessment model: GCAM-USA. (JOURNAL)
Integrated Assessment Models (IAMs) characterize the interactions among human and earth systems. IAMs typically have been applied to investigate future energy, land use, and emission pathways at global to continental scales. Recent directions in IAM development include enhanced t...
Assessment of Uinta Basin Oil and Natural Gas Well Pad Pneumatic Controller Emissions (JOURNAL)
In the fall of 2016, a field study was conducted in the Uinta Basin Utah to improve information on oil and natural gas well pad pneumatic controllers (PCs) and emission measurement methods. A total of 80 PC systems at five oil sites (supporting six wells) and three gas sites (sup...
A Laboratory Comparison of Emission Factors, Number Size Distributions, and Morphology of Ultrafine Particles from 11 Different Household Cookstove-Fuel Systems (JOURNAL)
Ultrafine particle (UFP) emissions and particle number size distributions (PNSD) are critical in the evaluation of air pollution impacts on human health and climate change. Residential cookstove emissions are a major source of many air pollutants; however, data on UFP number emis...
Evidence that higher [CO2] increases tree growth sensitivity to temperature: a comparison of modern and paleo oaks (JOURNAL)
Aim: To test the growth-sensitivity to temperature under different ambient CO2 concentrations, we determined paleo tree growth rates as they relate to variation in temperature during the last deglacial period, and compare these to modern tree growth rates as they relate to spatia...
Longitudinal thermal heterogeneity in rivers and refugia for coldwater species: effects of scale and climate change (JOURNAL)
Climate-change driven increases in water temperature pose multiple challenges for aquatic organisms. Predictions of climate change impacts to biota typically do not account for fine-grained spatiotemporal patterns of stream networks; yet patches of cooler water within rivers c...
Universal industrial sectors integrated solutions modulefor the pulp and paper industry (JOURNAL)
The U.S. is the world’s second-leading producer of pulp and paper products after China. While the pulp and paper industry has reduced its environmental impacts, concerns remain regarding the emissions of oxides of nitrogen (NOX) and sulfur dioxide (SO2) from the sector. Boilers, ...
Extreme Precipitation and Emergency Room Visits for Influenza in Massachusetts: A Case-Crossover Analysis (JOURNAL)
BACKGROUND: Influenza peaks during the wintertime in temperate regions and during the annual rainy season in tropical regions – however reasons for the observed differences in disease ecology are poorly understood. We hypothesize that episodes of extreme precipitation also result...
Evaluation of an Air Quality Health Index for Predicting the Mutagenicity of Simulated Atmospheres (JOURNAL)
No study has evaluated the mutagenicity of atmospheres with a calculated air quality health index (AQHI). Thus, we generated in a UV-light-containing reaction chamber two simulated atmospheres (SAs) with similar AQHIs but different proportions of criteria pollutants and evaluated...
Environmental effects of ozone depletion, UV radiation and interactions with climate change: UNEP Environmental Effects Assessment Panel, update 2017 (JOURNAL)
The Environmental Effects Assessment Panel (EEAP) is one of three Panels of experts that inform the Parties to the Montreal Protocol. The EEAP focuses on the effects of UV radiation on human health, terrestrial and aquatic ecosystems, air quality, and materials, as well as on the...
A likelihood-based time series modeling approach for application in dendrochronology to examine the growth-climate relations and forest disturbance history (JOURNAL)
A time series intervention analysis (TSIA) of dendrochronological data to infer the tree growth-climate-disturbance relations and forest disturbance history is described. Maximum likelihood is used to estimate the parameters of a structural time series model with components for ...
Regional patterns of increasing Swiss needle cast impacts on Douglas-fir growth with warming temperatures. (JOURNAL)
The fungal pathogen, Phaeocryptopus gaeumannii, occurs wherever Douglas-fir is found but disease damage is believed to be limited in the Pacific Northwest (PNW) to the Oregon Coast Range and is of no concern outside the coastal fog zone [1]. However, knowledge remains limited on...
Impacts of a large boreal wildfire on ground level atmospheric concentrations of PAHs, VOCs and ozone (JOURNAL)
During May 2016 a very large boreal wildfire burned throughout the Athabasca Oil Sands Region (AOSR) in central Canada, and in close proximity to an extensive air quality monitoring network. This study examines speciated 24-h integrated polycyclic aromatic hydrocarbon (PAH) and v...
Climate change damages to Alaska public infrastructure and the economics of proactive adaptation (JOURNAL)
Climate change in the circumpolar region is causing dramatic environmental change that increases the vulnerability of the built environment. We quantified the economic impacts of climate change on Alaska’s public infrastructure under relatively high and low climate forcing scenar...
Climate Change Impacts on Harmful Algal Blooms in U.S. Freshwaters: A Screening-Level Assessment (JOURNAL)
Cyanobacterial harmful algal blooms have serious adverse effects on human and environmental health. Herein, we develop a modeling framework that predicts the effect of climate change on cyanobacteria concentrations in reservoirs in the contiguous U.S. The framework, which uses cl...
Climate Change Impacts on US Water Quality using two Models: HAWQS and US Basins (JOURNAL)
Climate change and freshwater quality are well-linked. Changes in climate result in changes in streamflow and rising water temperatures, which impact biochemical reaction rates and increase stratification in lakes and reservoirs. Using two water quality modeling systems (the Hydr...
