People around the world seek climate risk information to guide their decisions. For instance, projections about future flood risk inform where households choose to live, how lenders manage credit risks, and which communities receive federal funding. Yet data limitations and fundamental validation challenges raise important concerns about the reliability of such projections. The principles of transparency and reusability help address these concerns by enabling scrutiny of assumptions and methods, development of foundational data and tools, and consistent application of evaluation standards. While there is ongoing debate about how much transparency commercial climate risk services should provide, many expect noncommercial actors …

Rethinking Geoengineering Governance Utilizing The Playing God Argument: Considerations Of Knowledge, Control, And Benevolence, Julian Dreiman, Brian Patrick Green

Staff Publications and Research

Because greenhouse gas emissions continue to grow, it is increasingly challenging to limit global warming to 1.5 or 2.0 degrees Celsius. As such, there is a growing debate on whether or not to deploy geoengineering to reduce warming. Geoengineering is controversial, and many arguments have been raised against it, including the “playing God” critique. When understood through the philosopher Moti Mizrahi’s reinterpretation, the playing God critique does not eliminate the possibility of using geoengineering, but rather informs how its governance can be improved. We use Mizrahi’s interpretation of the playing God critique to claim that the existing governance literature lacks …

21st-Century Mangrove Expansion Along The Southeastern United States, Lucia I.A. Enes Gramoso, Dustin Carroll, Kyle C. Cavanaugh, Remi Bardou, Michael J. Osland, Tom Van Der Stocken

Faculty Research, Scholarly, and Creative Activity

Warming winter temperatures are driving range expansion of tropical, cold-sensitive mangroves into temperate ecosystems. Along the Atlantic coast of North America, the mangrove range limit is particularly sensitive to climate variability and historical data demonstrate that the mangrove-salt marsh ecotone on this coast has shifted recurrently during recent centuries. However, a comprehensive understanding of how this mangrove-salt marsh ecotone may shift in the future remains lacking. Here, we combine ensemble forecasting of mangrove distribution for the next century with high-resolution oceanographic dispersal simulations, phenological observations, and historical hurricane data to project future mangrove-salt marsh dynamics at the rapidly changing range …

Climate Change Impacts On Forest Canopy Temperatures: From Mechanisms To Implications, William Hagan Brown

School of Geography, Earth and Environmental Sciences Theses

Forests are a vital interface between the biosphere and the atmosphere. As global temperatures rise due to increasing anthropogenic greenhouse gas emissions, it is important to understand the response of forest tree canopy leaf temperature (T_can). Additionally, understanding variation in T_can and regulation across species within ecosystems is crucial for understanding how climate change affects plants. Thus, this research aimed to measure T_can in temperate and tropical forests under contrasting environmental conditions to advance understanding of T_can. At the Birmingham Institute of Forest Research Free-Air CO₂ Enrichment (BIFoR-FACE) site, continuous thermal infrared (TIR) …

Mapping Coastal Vegetation To Evaluate Salt Marsh Decline From 2016 To 2025 In South Carolina, Usa, Zak Henry Bartholomew

Theses, Dissertations and Capstones

Accelerating sea-level rise and storm surge events pose a substantial threat to salt marsh ecosystems, which provide critical ecosystem services. Classification and mapping of coastal vegetation through remote sensing can identify marsh dieback events and provide spatial context for patterns of marsh vulnerability. We used a multi-sensor approach that incorporated LiDAR data, multispectral imagery, and field-derived cover estimates to classify Spartina alterniflora (smooth cordgrass) dominated marsh types on Marine Corps Recruit Depot Parris Island (MCRDPI), a sea island in South Carolina, USA. In summer 2025, surveys were conducted within marsh classes to collect training and validation data. We used random …

Lake As Body: Ecofeminism And Animacy At The Great Salt Lake, Shae Barber

Graduate Student Theses, Dissertations, & Professional Papers

Water shapes cultural, social, and ecological systems. Yet, dominant economic, political, and academic frameworks often treat water as a backdrop or passive resource, ignoring it as an active participant in meaning-making and relationship-building. Viewing water as “nonliving” obscures how it participates in and co-creates relationships, limiting understanding about impacts of and responses to climate change and environmental degradation.

This thesis takes a mixed-methods and participatory approach including semi-structured interview, photovoice, and participatory mapping to examine relational practices between environmental advocates and the Great Salt Lake, a desiccating saline lake in Utah, U.S. As the lake continues to decline, dominant Western …

Increasing Temperatures And Heatwave Durations Negatively Affect The Performance Of A Dietary Generalist, Kailey G. Hicks, Claire Guzinski, Mariana Abarca, Mayra C. Vidal, Audrey M. Mitchell, Dhaval K. Vyas, Shannon M. Murphy

Biological Sciences: Faculty Publications

Climate variability has increased in recent decades, and this trend is predicted to continue. Globally, there is a rise in extreme temperatures, such as heatwaves, which are strengthening in both intensity and frequency. As ectotherms, insects are especially affected by temperature variation. Insects are the most speciose group of animals and important members of most terrestrial ecosystems, providing critical ecosystem services. Most studies of global change have investigated only a single stressor, yet insects rarely experience one stressor at a time. Two stressors that co-occur are heatwaves and warming temperature regimes; thus, is it important that we study their interaction …

Climate Change Impacts On Hydrology In The Upper James Watershed, Imiya Mudiyanselage Chathuranika, Dalya Ismael

Engineering Technology Faculty Publications

Hydrological modeling of the Upper James Watershed (UJW), Virginia, is critical for predicting water availability, flood management, agriculture, ecosystem protection, and hydropower production under increasing climate change. The Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) is applied to evaluate climate change impacts on key hydrological components within the watershed. Future climate conditions were assessed for the near (NF: 2026-2050), mid (MF: 2051-2075), and far (FF: 2076-2100) periods using three Global Climate Models (GCMs) under Shared Socioeconomic Pathways SSP 2-4.5 and SSP 5-8.5. Climate data were bias-corrected using the Linear Scaling Method (LSM) and used to drive the HEC-HMS model. Results project …

Climate Change In Gilgit-Baltistan: Satellite-Based Land Use/Land Cover Change Detection, Socio-Economic Dimensions, And Adaptation Strategies, Ali Muhammad

Graduate Theses/Dissertations

Climate change is increasingly transforming the cryosphere, hydrology, and human landscape of Gilgit-Baltistan, a highly climate-sensitive mountain region in northern Pakistan. This thesis investigates these transformations through satellite-based land use/land cover (LULC) change detection in four representative tehsils of Gilgit-Baltistan—Ali Abad, Gilgit, Nagar, and Sikander Abad—selected to span a gradient of human pressure and cryospheric exposure within the region. Using summer, cloud-free (< 10%) imagery from USGS Landsat 7 (2000) and Landsat 8 (2025), it conducts a multi-temporal comparison of environmental and socio-spatial change. After atmospheric correction and band compositing, the imagery is classified in ArcGIS Pro into six classes—Water, Barren land, Vegetation, Snow, Glacier, and Built-up—using a Support Vector Machine (SVM) classifier, with Maximum Likelihood Classification and Random Forest also tested but found less suitable for the final workflow. The analysis detects a pronounced reduction in mapped glacier-class area alongside a comparatively stable snow class, together with built-up expansion, while examining how temperature, precipitation, tourism, and population dynamics relate to observed LULC transitions. The results reveal a pattern of cryospheric decline and urban growth, with implications for water availability, ecological stability, hazard exposure, and settlement pressure. By integrating geospatial change detection with climatic and socio-economic interpretation, the thesis moves beyond mapping to explain interacting environmental and human drivers of landscape transformation and provides a reproducible remote-sensing baseline for monitoring land-surface change in heterogeneous mountainous terrain. It recommends integrated water-resource management, climate-resilient land-use planning, watershed and glacier monitoring, and sustainable tourism governance, supporting evidence-based decision-making by the Government of Gilgit-Baltistan and organizations working on climate adaptation, disaster risk reduction, and sustainable regional development.

Resilient Built Environment: An Overview On Design Strategies For Coastal Adaptation To Sea Level Rise, Farzaneh Soflaei, Gelareh Abdolzadeh, Navid Ziaee, Mohammad Amin Jafari, Faeghe Borhani

Civil & Environmental Engineering Faculty Publications

This paper delves into the escalating risks faced by urban coastal communities due to tidal and storm flooding, exacerbated by climate change-induced Sea Level Rise (SLR). Projections indicate a potential increase in sea levels by at least 3 feet by 2100, with historical data revealing an average annual rise of 1.2-1.7 mm since the 1900s. With over 300 million individuals inhabiting coastal areas, low-lying regions emerge as particularly vulnerable to the impacts of SLR. This accelerated rise amplifies the significant challenge of nuisance flooding, a local-scale issue aggravated by high tide and winds, leading to inundation, road closures, infrastructure deterioration, …

Madison, Wisconsin As A Climate Haven: Infrastructure, Environmental Justice, And Community Voice, Sophia N. Heffner

Scripps Senior Theses

As climate change accelerates internal migration within the United States, the concept of “climate havens” has emerged as a way to identify communities that may become receiving zones for displaced populations. Madison, Wisconsin has increasingly been positioned within academic, policy, and media discourse as a potential climate haven due to its geographic advantages, strong public infrastructure, and proactive climate policy environment. This paper evaluates Madison’s readiness for this role through an equity-centered, participatory planning lens. Drawing on planning documents, climate data, municipal policies, and interdisciplinary scholarship, it argues that Madison’s long-term success as a sustainable and inclusive climate haven depends …

School of Geography, Earth and Environmental Sciences

Net primary production in the Southern Ocean plays a critical role in governing ecosystem production, the biological carbon pump, and global biogeochemical cycles. Recent work has advanced our understanding of novel factors regulating Southern Ocean net primary production and the regional physiological adaptations employed by Southern Ocean phytoplankton in terms of their photosynthetic strategies and resource acquisition. Here we assess trends in Southern Ocean net primary production from different remote sensing algorithms and bgc-Argo floats to compare them to the latest Earth System Models used to forecast future changes under three different future climate scenarios. Overall, remote sensing and bgc-Argo …

The Disaster Management Complex: Law’S Adaptations In Times Of Climate Disaster, Michael Burger, Jeffrey Schlegelmilch, Lucia Bragg

Sabin Center for Climate Change Law

The Anthropocene is marked by constant climate-related disasters and defined by the urgent need to foster and implement adaptations to future climate impacts that reduce disaster risk. The intensity, frequency, and severity of extreme weather events continue to rise even as nations and corporations alike miss their emissions targets, all promising a hotter, wetter, and more extreme future. A number of federal agencies, including the Federal Emergency Management Agency (FEMA), have, at times, sought to adapt their own famously fragmented responses to these changing circumstances. However, federal disaster response is conducted against a backdrop of authorizing legislation that is designed …

Addressing Critiques Refines Global Estimates Of Reforestation Potential For Climate Change Mitigation, Kurt A. Fesenmeyer, Erin E. Poor, Drew E. Terasaki Hart, Joseph W. Veldman, Forrest Fleischman, Pooja Choksi, Sally Archibald, Mohammed Armani, Matthew E. Fagan, Evan C. Fricke, César Terrer, Natalia Hasler, Christopher A. Williams, Peter W. Ellis, Susan Cook-Patton

Geography

Reforestation is a prominent climate change mitigation strategy, but available global maps of reforestation potential are widely criticized and highly variable, which limits their ability to provide robust estimates of both the locations and total area of opportunity. Here we develop global maps that address common critiques, build on a review of 89 reforestation maps created at multiple scales, and present eight reforestation scenarios with varying objectives, including providing ecosystem services, minimizing social conflicts, and delivering government policies. Across scenarios, we find up to 195 Mha (million hectares) are available (2225 TgCO2e (teragrams of carbon dioxide equivalent) per year total …

The Pluralistic Natural Capital Values Of A Tropical City, Adrienne Gret-Regamey, Et Al.

Research Collection College of Integrative Studies

Nature in cities is essential for human well-being. Quantifying and valuing the goods and services provided by nature to city dwellers is missing in tropical contexts. Yet, as cities worldwide face similar challenges, understanding the services provided by tropical urban ecosystems becomes imperative for effective management. Here, we present the first Natural Capital Assessment of a tropical city, unveiling three critical insights. Firstly, we demonstrate the vital reliance of a developed tropical city on nature, particularly for climate change mitigation through regulating services. Secondly, we identify intact natural areas as Singapore’s most valuable assets, stressing the significance of the quality …

A Capital Idea? The Welfare Effects Of Relocating Indonesia’S Government To A New City, Alexander D. Rothenberg, Radine Rafols, Yao Wang, Yi Jiang

Center for Policy Research

Many developing countries are planning to create new capital cities, a place-making policy designed to alleviate congestion and respond to climate change. To evaluate growth and welfare effects, we specify a dynamic quantitative spatial model with public employment, informality, fiscal transfers, and frictions in trade and migration. We calibrate the model with data from Indonesia and conduct policy experiments studying the creation of Nusantara in East Kalimantan. Despite increasing employment in the new capital region, we find that building Nusantara reduces national growth and welfare. Climate change attenuates its negative welfare effects, but only slightly.

Wine-Rs Or Losers: Assessing The Socio- Economic Impact Of Eu Regulations On Climate-Exacerbated Pests And Diseases In Northern Italian Viticulture, Kyley Fishman

Claremont-UC Undergraduate Research Conference on the European Union

As climate change creates extreme weather events, unprecedented disease and pest infestations, European farmers are challenged by these threats. Balancing sustainable and traditional practices while maintaining socio-economic stability under European Union agroregulations can be extremely difficult. An area of concern for the EU is viticulture, which is among the most climate-sensitive agricultural sectors. My study examines in what ways the EU’s regulations addressing climate-exacerbated pests and plant diseases influence the socioeconomics of different vineyard farms in Northern Italy. Three key socio-economic findings emerged from the analysis. First, top-down and research-driven management strategies can subvert local, place-based knowledge, which undermines traditional …

Repairing Epistemic Injustice And Loss In The Era Of Climate Coloniality, Farhana Sultana

Geography and the Environment - All Scholarship

Climate change intensifies existing inequities, disproportionately impacting marginalised populations, particularly in the Global South and Indigenous communities. This is maintained through inequitable global climate governance, policies and solutions. The paper argues that climate coloniality, the complex entanglements of colonial legacies with contemporary climate and ecological changes, operates through systemic knowledge-based marginalisation or epistemic injustice, serving as a key mechanism in the uneven production and distribution of climate harms. Beyond the more commonly discussed material dimensions of loss and damage, epistemic injustices arise from silencing critical voices and devaluing knowledge systems. The paper extends the scope of loss and damage debates …

Snow Avalanches And The Impact Of Climate‐Linked Extreme Events On Mountain Wildlife Population Dynamics And Resilience, Kevin S. White, Taal Levi, Eran Hood, Chris T. Darimont

Faculty, Staff, and Students

Climate is changing rapidly in mountain environments, giving rise to increasing variability in weather, incidence of extremeevents, and alteration of the cryosphere. Natural hazards, such as snow avalanches, and the ecological communities they impactmay be particularly sensitive to such change. While avalanches may impose both ‘good’ and ‘bad’ effects on mountain ecosys-tems, the direct impacts that lead to mortality have particularly important implications for future viability and resilience ofslow-growing alpine wildlife populations. Here, we studied a sentinel species of coastal Alaskan mountain environments—themountain goat (Oreamnos americanus) – using long-term field data from individually marked animals (600 individuals over44 years) in …

Socio-Economic Risk Of Rising Compound Precipitation-Wind Extremes In San Francisco Bay Area, Nikhil Kumar, Gregory Brian Pasternack, Yufang Jin, Serena Alexander, Zhihao Wang, Costanza Rampini, Rune Storesund, Chris Lim, Stephanie Moreno, Igor Lacan

Faculty Research, Scholarly, and Creative Activity

Compound precipitation-wind extremes (CPWEs) pose significant socio-economic challenges in urban areas, with the most severe impacts often felt by vulnerable populations. While CPWE studies have often focused on large-scale assessments, localised urban contexts, at a scale of a city and its suburban surroundings, remain understudied, particularly in terms of how CPWEs might differentially impact different socio-economic communities. This study aims to advance understanding of how CPWEs interact with social vulnerability at a localised scale, using the San Francisco Bay Area (SFBA)—a global hotspot for CPWEs with diverse climates, physiography, and socio-economic factors—as a test case. Daily precipitation and wind speed …

Alpine Plants And Climate Change: Tracking Community Shifts In Yosemite National, Brooke L. Wallasch

Master's Theses

As climate change progresses, alpine plant communities are predicted to shift upslope as they track temperature over time. Relative to lowland environments, alpine areas are experiencing a faster rate of temperature change due to a phenomenon referred to as elevation-dependent warming. A common approach for tracking plant communities shifts over time, is to conduct resurveys of the same area at several time points, as the Global Observational Research Initiative in Alpine Environments (GLORIA) has done on mountain summits around the world since 2001. In 2011-2013, GLORIA developed a supplemental survey method whereby belt transects were established downslope of summits in …

Adapting To Change In Amenity-Oriented Communities: Innovative Strategies For Shifting Social And Environmental Needs, Emma L. R. Epperson

All Graduate Theses and Dissertations, Fall 2023 to Present

Amenity-oriented communities are places with significant and desirable natural amenities that are highly visited and plentiful within the Intermountain West. These high rates of visitation create complex challenges such as congestion in recreation spaces and in towns and increase costs of living. These communities are typically rural and often do not have the resources, funding, or infrastructure to combat these challenges. Although tourists provide financial stability and other amenities to these towns, local wellbeing is highly impacted. Outdoor recreation and the nature connections derived from outdoor experiences are major contributors to wellbeing in amenity communities. This research investigates the changes …
