Repurposed Energy
“Climate-induced wildfires, weather extremes, droughts, and floods add urgency to the project of accelerating the clean energy transition from fossil fuels to zero-carbon energy infrastructure. Yet the hurdles to accomplishing such a massive industrial-scale transition are daunting. Indeed, large renewable energy generation projects regularly face denials or project-killing delays across the United States. Klass’ talk will be based on her article that proposes a national policy of “repurposed energy” to channel the bulk of new clean energy projects to abandoned coal mines, retired coal plants, closed landfills, and other underutilized or abandoned urban and rural contaminated properties k...

Aligning with Recycling as a Strategy for Reliable Critical Metals Supply
Просмотров 3221 день назад
The processing and reprocessing of secondary materials is one of the key strategies to secure the supply of critical and energy transition metals in the U.S. Mine waste and end-of-life electronic and electric equipment are widely accepted as important sources of these critical metals. Black mass from waste batteries and printed circuit boards from electronic waste are examples of materials that...
Flying into the Future: Sustainable Aviation Fuel and the Policies Impacting its Development
Просмотров 76Месяц назад
As the world works to limit greenhouse gas emissions to mitigate the impacts of climate change across all sectors, air travel presents a particularly difficult challenge. Aviation contributes approximately 2.5% of the world’s greenhouse gas emissions, but unlike other portions of the transportation sector, it is unlikely that electrification will meaningfully reduce emissions from air travel. T...
"Land Acquisition for Carbon Sequestration"
Просмотров 45Месяц назад
Carbon sequestration will require massive amounts of subsurface property. Sequestration operators must acquire the rights to conduct geophysical characterization activities, inject and store CO2, construct facilities, monitor plumes, conduct corrective action on existing wellbores, and, eventually, abandon the CO2 in place. The acquisition of these rights adds cost and complexity to carbon remo...
Climate Science to Actionable Urban Solutions
Просмотров 467 месяцев назад
In the last century, research on urban systems dynamics has improved our understanding, leading to data-driven tools for effective urban management, including predictive analytics and simulation models. Despite these advances, achieving sustainability goals remains a challenge for cities. The historical focus on system-scale decisions must now consider the influence of urban gradients and their...
Exposure to Indoor PM2.5 and Impact of Outdoor-to-Indoor Temperature and Humidity Gradients
Просмотров 427 месяцев назад
Outdoor aerosols experience environmental changes when transported indoors, including outdoor-to-indoor temperature and humidity gradients, which can reduce or enhance indoor concentrations due to repartitioning driven by thermodynamic changes. Traditional models often overlook these phenomena, which can lead to inaccurate predictions of indoor aerosol exposure. This talk explores how we simula...
Low-cost Sensors for Environmental Health Applications
Просмотров 417 месяцев назад
The Internet of things has exploded the use of sensors in our day-to-day lives. This presentation will discuss the use of sensor data across the environmental health paradigm from emission of pollutants to exposure to health effects. Ambient, occupational, and personal monitoring approaches will be discussed, along with interventions to reduce exposures, with a focus on air pollution exposures....
The Dynamics of Neighborhood Integration and Segregation in the Past Four Decades
Просмотров 338 месяцев назад
American metropolitan areas remain segregated by race. Yet the factors that create the conditions that lead to segregation have changed. I document and classify neighborhood change that has occurred over the past four decades and explain how a lack of moves _into_ integrated neighborhoods not their flight out of integrated neighborhoods is a major factor that maintains segregation in the twenty...
City-HEAT: A Multi-objective, Uncertainty-based Planning Framework for Urban Heat Management
Просмотров 468 месяцев назад
Rising global temperatures and the urban heat island effect can amplify heat-related health risks to urban residents. Cities are considering various heat adaptation actions to improve public health, enhance social equity, and cope with future conditions beyond past experience. We present the City-Heat Equity Adaptation Tool (City-HEAT), which suggests optimal investments for mitigating urban he...
Modeling Spatial Variability of Urban Microclimate
Просмотров 2578 месяцев назад
Cities modify their local microclimate through changes in radiative, morphological, and thermal properties. Cities are also highly heterogeneous, leading to spatial variability in environmental exposure and climate risks. For instance, poor and disadvantaged communities in U.S cities often live in the warmest neighborhoods. While a lot of work has been done to improve urban representation in mo...
Cities, Climate Change, and Disease: How Can Science Help Humanity Solve Big Problems?
Просмотров 409 месяцев назад
Quantifying interactions between social systems and the physical environment we live within has long been a major scientific challenge. A better empirical understanding of dynamic interactions between the physical or natural context and urban social structure is necessary to support predictions of how people and cities might respond to climate change, disease, and other emergent threats, ensure...
The Economic Impacts of Carbon Emission Trading Scheme on Building Retrofits
Просмотров 609 месяцев назад
As a popular emission reduction tool, the carbon emission trading scheme (ETS) can potentially add an economic incentive for building owners to retrofit buildings in addition to the cost savings in energy. This study proposed a systematic economic evaluation method to investigate the economic impacts of ETS on building retrofits. The reduction of the payback period and the increase of the retur...
Challenges of Historic Urban Land Development and Soil Disturbance on Urban Stormwater Management
Просмотров 649 месяцев назад
Many of our older urban areas have undergone multiple phases of development over the course of several hundred years. Topography has been heavily modified; subsurface infrastructure has been constructed, often piecemeal over time; and the cities that result bear no resemblance to the predevelopment landscape. Urban development has resulted in the compaction of soil, which changed soil porosity ...
Bio-geo-socio-chemistry of Urban Watersheds
Просмотров 4010 месяцев назад
Abstract: The steadily rising global urban population has placed substantial strain on urban water quality, and this strain is projected to increase for the foreseeable future. Considerable attention has been given to the hydrological and physico-chemical effects of urbanization on stream ecosystems. However, due to the relative infancy of the field of urban ecology, long-term water quality ana...
Building SURE (Sustainable and Resilient) Communities

Buildings play a crucial role in the achievement of the Sustainable Development Goals (SDGs). They significantly impact resource consumption, environmental sustainability, and the well-being of individuals and communities. However, despite their importance, progress toward achieving an SDG-aligned building sector is "off track." This is in part because these goals are being pursued in isolated,...

uhhh, umm, uhhh, umm, terrible speaker
It sounds that the upper crust is thermally anisotropic. The difference in temperature in the lid..could that explain the generation of coronae? It was sounds that maybe Mercury has a stagnant lid, Venus may be someplace on a line between between a stagnant lid and an active lid and Mars is in between. Possibly Mercury and Venus at the moment. Does this make sense to you?
This is great. This is actually helping me out with my own astrobiology homework.
That's so inspiring and well-alligned with my research interest. I am open to any opportunity in your research group Thanks for this presentation.
