Wildfires have increased in frequency and area burned, trends expected to continue with climate change. Among other effects, fires release pollutants into the atmosphere, representing a risk to human health and downwind terrestrial and aquatic ecosystems. While human health risks...

Accurate fire emissions inventories are crucial to predict the impacts of wildland fires on air quality and atmospheric composition. Two traditional approaches are widely used to calculate fire emissions: a satellite-based top-down approach and a fuels-based bottom-up approach. H...

Microplastics (MPs) are an emerging class of pollutants in air, soil, and, especially, in all aquatic environments.  Secondary MPs are generated in the environment during fragmentation of especially photo-oxidized plastic litter. Photo-oxidation is mediated primarily by sola...

Journal article submitted to EcoHealth - (Abstract) - Lyme disease (LD) is the most common vector-borne disease in the United States (U.S.). This paper assesses how climate change may influence LD incidence in the eastern and upper midwestern U.S., and the associated economic bur...

Atmospheric nitrogen (N) and sulfur (S) deposition can significantly affect forest biodiversity and production by altering the growth and survival of trees. Three decades of air quality regulations in the United States have led to large reductions in oxides of N (44–81%) an...

Over the past half-century or more, economists have developed a robust literature on the theory and practice of benefit-cost analysis (BCA) as applied to diverse projects and policies. Recent years have seen a growing demand for practical applications of BCA to climate change pol...

This paper discusses the challenges inherent in developing benefit-cost analysis (BCAs) of climate change. Challenges are explored from three perspectives: meeting the foundational premises for conducting BCA within the framework of welfare economics, methodological consideration...

Nitrogen (N) has historically been the nutrient that most often limits plant growth in the United States. However, human activity since the Industrial Revolution has resulted in increased emission and hence deposition of N.1 Initial increases in N deposition can act as a fertiliz...

Freshwater ecosystems, including lakes, streams, and wetlands, are responsive to climate change and other natural and anthropogenic stresses. These ecosystems are generally hydrologically connected with one another and with the landscapes around them, integrating changes that occ...

Increasing climate ambition through 2030 will be crucial to limiting global peak temperature changes this century. Countries need to ratchet their 2030 pledges made in Glasgow to reduce temperature overshoot and consequently reduce the risks of irreversible and adverse consequenc...

The authors designed and executed the integrated assessment modeling for the United States long-term strategy. They bring diverse expertise to the modeling and analysis of United States decarbonization.

Current climate pledges are insufficient to achieve the aspirational goal of limiting global warming to 1.5°C. Here, we discuss the critical role that non-CO2 greenhouse gas emissions might play in global climate change stabilization and challenges and opportunities to pivot rese...

King et al. raise important issues, several of which pertain to the broader policy discourse surrounding international climate negotiations and countries’ climate pledges rather than the modeling conducted in our Policy Forum. We agree with King et al. that the updated Paris Agre...

As countries take stock of progress made in accomplishing their climate goals ahead of COP28 this year, it is increasingly apparent that countries must ratchet ambition in policy areas such as non-CO2 gases and carbon dioxide removal, while halting deforestation to lead the globe...

A manuscript describing an analysis to produce an updated value for the ozone-related health impacts of methane emissions, relevant to social cost of carbon calculations.

The new and updated emission reduction pledges submitted by countries ahead of the Twenty-Sixth Conference of Parties represent a meaningful strengthening of global ambition compared to the 2015 Paris pledges. Yet, limiting global warming below 1.5 °C this century will require co...

If goals set under the Paris Agreement are met, the world may hold warming well below 2°C (1); however, parties are not on track to deliver these commitments (2), increasing focus on policy implementation to close the gap between ambition and action. Recently, the US government p...

This study utilizes the reduced-complexity model, Framework for Evaluating Damages and Impacts (FrEDI), to rapidly assess economic and physical impacts of climate change in the contiguous United States (U.S.).

A manuscript describing the development of annual and monthly gridded time-resolved methane emissions from the Inventory of U.S. Greenhouse Gas Emissions and Sinks

Communities across the United States are enduring, often unexpectedly, the effects of extreme events, such as excessive heat, prolonged droughts, extreme floods, and wildfires. In places where contaminated sites and waste management facilities are also present, communities must c...

Understanding how heat waves affect morbidity and mortality, as well as the associated economic costs, is essential for characterizing the human health impacts of extreme heat under a changing climate. Only a handful of studies have examined healthcare costs associated with expos...

Future estimates of atmospheric pollutant concentrations serve as critical information for policy makers to formulate current policy indicators to achieve future targets. Tropospheric burden of O3 is modulated not only by anthropogenic and natural precursor emissions, but also ...

Environmental managers responsible for the oversight and management of aboveground storage tanks (ASTs) can benefit from increased awareness of vulnerabilities, risks, and increased environmental impacts associated with climate change. In this context, we are focused on the physi...

Wildland fires, which includes both wild and prescribed fires, and agricultural fires in sum is one of the largest sources of fine particulate matter (PM2.5) emissions to the atmosphere in the United States. Although wildland fire PM2.5 emissions are primarily composed of carbona...

Abstract: Individuals with psychosocial stress often experience an exaggerated response to air pollutants. Ozone (O3 ) exposure has been associated with the activation of the neuroendocrine stress-response system. We hypothesized that preexistent mild chronic stress plus social i...
