Witnessing Climate Change In The United States Virgin Islands: Emotional Responses And Calls For Action, Thomas Bane

Dissertations, Theses, and Capstone Projects

Climate change is one of the greatest threats facing humanity in the 21^st century. This study investigated people’s observations of climate change in the United States Virgin Islands (USVI). A qualitative study was used with a Grounded Theory approach to better understand how people witnessed climate change events, what people’s emotional responses were, and what calls for action they had to respond to climate change in the USVI. The study had two parallel arms: five focus groups (n=17) with residents of the USVI and key informant interviews with community leaders (n=10). Participants witnessed a wide …

Rural And Urban Difference In The Acceptance Of Alternative Water Management Strategies: Case Study Of Idaho Residents, Monica L. Hubbard, Rebecca L. Som Castellano

Public Policy and Administration Faculty Publications and Presentations

Idaho is one of the fastest-growing states in the US. The stressors of population growth and climate change are increasing the strain on its water resources, emphasizing the need for water management strategies. Public support, however, can vary by a range of factors, including geography. This study aims to assess the rural and urban distinctions of support for water resource management. In 2014, 401 people from Idaho’s general public responded to an online survey, with 375 of the respondents georeferenced into three groups: urban areas; urban clusters (small towns); and rural. The responses showed similarities in support among the groups; …

Land Dispossession And Native American Climate Adaptation: The Hopi Tribe, Jessica M. Curran

Student Theses 2015-Present

Since the 16th century, Native American communities have lost over 99% of their historical land. New settlers came in and completely destroyed the natives’ way of life, disregarding the love and respect that was once shown for mother earth. Flash forward to the 21st century and we are now struggling with the constant rising threat of climate change. However, this is not an equal fight. Past studies have shown that Native American communities are more vulnerable to climate change hazards compared to the general United States population due to their existing disparities. This paper focuses on the Hopi Tribe and …

Energy And Climate Change Issues Around Csudh, Alex E. Perez, Tara B. Jones, Raju Bista, Parveen K. Chhetri

CSU Journal of Sustainability and Climate Change

Climate change is posing significant challenges to California’s energy sector. Extreme weather events (heat and cold) may pressure existing infrastructure. Many studies have indicated that extreme climate events would impact the energy system by affecting peak electricity demand. However, very few studies have been conducted to understand how disadvantaged communities (DACs) will be impacted. Because of unequal access to energy infrastructure (electricity generation and battery storage), DACs are more vulnerable to power outages due to the rising number of significant weather events caused by climate change. To address the issue of how DACs are disproportionately affected by climate change-related energy …

Diversification Of Refugia Types Needed To Secure The Future Of Coral Reefs Subject To Climate Change, Tim R. Mcclanahan, Emily S. Darling, Maria Beger, Helen E. Fox, Hedley S. Grantham, Stacy D. Jupiter, Cheryl A. Logan, Elizabeth Mcleod, Lisa C. Mcmanus, Remy M. Oddenyo, Gautam S. Surya, Amelia S. Wenger, Jens Zinke, Joseph M. Maina

Marine Science Faculty Publications and Presentations

Identifying locations of refugia from the thermal stresses of climate change for coral reefs and better managing them is one of the key recommendations for climate change adaptation. We review and summarize approximately 30 years of applied research focused on identifying climate refugia to prioritize the conservation actions for coral reefs under rapid climate change. We found that currently proposed climate refugia and the locations predicted to avoid future coral losses are highly reliant on excess heat metrics, such as degree heating weeks. However, many existing alternative environmental, ecological, and life-history variables could be used to identify other types of …

Relationships Between Vector Mosquitoes And Climate Change Derived From Long Term Ecological Data In The United States, Nicholas Scott

Honors Program Theses and Projects

Climate change has significant ecological and societal consequences as evident from the past few decades. It has had a large impact on many species, including vector mosquitoes. Although how climate change impacts mosquitoes of the tropical world has been explored, temperate areas remain inadequately studied. Therefore, the medical and healthcare sectors are underprepared for treating mosquito-borne diseases (EEE and Western Nile virus). Based on a long-term ecological dataset covering the past ~10 years across 45 sites, we streamlined, processed, and subsequently analyzed data by building statistical models to understand changes among mosquito populations in the US in response to climate …

Towards A Just Transition Impact Assessment Framework, Adebayo Gbenga Majekolagbe

PhD Dissertations

Just transition is a contested notion. Its definitions range from status quo enforcing to transformation engendering. Traditionally, just transition focuses on local jobs and workers. Its application within the climate change context retains this traditional focus. From its recognition in the Paris Agreement to its incorporation in domestic transition laws and policies, just transition is essentially interpreted as jobs transition. Further, the scholarship and law of just transition are primarily normatively built on the distributive and procedural conceptualizations of justice. Also, although planning is construed as central to a just transition, there is no clarity on how abstract proposals on …

Climate Change, Food Security, And The Myth Of Unlimited Abundance, Susan A. Schneider

Journal of Food Law & Policy

The Biden-Harris White House can be commended for convening the historic White House Conference on Hunger, Nutrition, and Health highlighting the critical connections between access to healthy food and sustaining a healthy population. This article explores the impact of climate change and seeks to fill a critical gap in the national discussion. It argues that dramatic changes are needed in the way we think about domestic food security and that meaningful change will be required to assure an adequate supply of healthy food, as envisioned by the White House Conference. It explores the impact of the changes to the climate …

Grid Governance In The Energy-Trilemma Era: Remedying The Democracy Deficit, Daniel E. Walters, Andrew N. Kleit

Faculty Scholarship

Transforming the electric power grid is central to any viable scenario for addressing global climate change, but the process and politics of this transformation are complex. The desire to transform the grid creates an “energy trilemma” involving often conflicting desires for reliability, cost, and decarbonization; and, at least in the short run, it is difficult to avoid making tradeoffs between these different goals. It is somewhat shocking, then, that many crucial decisions about electric power service in the United States are made not by consumers or their utilities, nor by state public utilities commissions or federal regulators. Instead, for much …

Investigating Consistency Of Landscape-Scale Green Infrastructure In Local Government Policy, Anna Wilson

All Theses

Planning for Climate Change is multifaceted and requires effort across all scales. Green Infrastructure networks of green spaces, natural lands, reserves, working lands, core habitat, riparian corridors, parks, open spaces, private conservations lands, and other complementary land uses work together to support life on earth and human existence through the ecosystem services provided. Clean air, clean water, carbon sequestration, food production, recreation, pollination, and spiritual and cultural benefits are only a few of the services that natural lands provide society. With climate change occurring due to human actions such as land use, development, and energy use, to name a few, …

Net-Zero Target And Emissions From Land Conversions: A Case Study Of Maryland's Climate Solutions Now Act, Philip Hutton

All Theses

Many climate change “solution” plans include net-zero goals, which involve balancing the anthropogenic greenhouse gas emissions (GHG) with their removal. Achieving net-zero goals is particularly problematic for soils because they are often excluded from GHG inventories and reduction plans. For example, Maryland’s Climate Solutions Now Act (Senate Bill 528) put forward a target of net-zero emissions by 2045. To achieve these goals, the state of Maryland (MD) needs to quantify GHG emissions. Soils are currently excluded from MD’s GHG assessments. This study examines the challenges in meeting net-zero goals by using carbon dioxide (CO₂). The current study quantified …

Transferred Emissions Are Still Emissions: Why Fossil Fuel Asset Sales Need Enhanced Transparency And Carbon Accounting, Jack Arnold, Martin Lockman, Perrine Toledano, Martin Dietrich Brauch, Shraman Sen, Michael Burger

Columbia Center on Sustainable Investment

In a widely reported trend, the “Oil Supermajors” — BP, Chevron, ConocoPhillips, Eni, ExxonMobil, Shell, and TotalEnergies — are selling off many upstream fossil fuel assets.

Selling these assets to entities that will continue producing and selling the fossil fuel resources does not necessarily reduce greenhouse gas emissions, but the supermajors have used these asset sales to support claims that they are making progress toward reaching net-zero greenhouse gas emissions.

Emissions reporting frameworks allow companies to conflate the apparent emissions reductions from asset sales with direct reductions from efficiency improvements and asset retirements. In doing so, they hinder the ability …

Mapping The Impacts Of Climate Change On Mediterranean Viticulture, Zoe A. Knauss

Standard Theses

Climate change will have a profound impact on viticulture across the planet in the coming decades. Viticulture in the Mediterranean Basin will be disproportionately affected, as it is considered a climate change hotspot. This study focuses on how the vineyards of three notable wine regions in southern France will be affected by projected changes in average annual temperature, total annual precipitation, average length of droughts, and average volumetric soil water (VSW) content in layer 1 soils due to climate change. Vineyard soils will also be affected by climate change in this region, indirectly impacting grape cultivation as well. A GIS …

The Effects Of Recent Climate Change On Spring Phenology, With A Special Focus On Patterns Of Bee Foraging, Michael Stemkovski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The date on which plants flower and on which bees begin to pollinate varies year-to-year depending on differences in weather. This seasonal timing is known as phenology, and it is already clear that climate change has pushed the spring phenology of many species earlier by increasing temperatures. This is particularly clear in flowering plants, but studying how and why the phenology of pollinators is shifting is more difficult. Most flowering plants rely on pollinators such as bees for their reproduction, and most bees rely on flowers for their sustenance, so bee and flower phenology has to overlap for the crucial …

The Compound Risk Of Heat And Covid-19 In New York City: Riskscapes, Physical And Social Factors, And Interventions, Janelle Knox-Hayes, Juan Camilo Osorio, Natasha Stamler, Maria Dombrov, Rose Winer, Mary Hannah Smith, Reginald Blake, Cynthia Rosenzweig

Publications and Research

Climate change is disrupting the fundamental conditions of human life and exacerbating existing inequity by placing further burdens on communities that are already vulnerable. Risk exposure varies by where people live and work. In this article, we examine the spatial overlap of the compound risks of COVID-19 and extreme heat in New York City. We assess the relationship between socio-demographic and natural, built and social environmental characteristics, and the spatial correspondence of COVID-19 daily case rates across three pandemic waves. We use these data to create a compound risk index combining heat, COVID-19, density and social vulnerability. Our findings demonstrate …

Climate Change, Site Formation, And Indigenous Use Of Coastlines In Barbuda, Isabel C. Rivera-Collazo, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

This article explores the landscape dynamics at the island of Barbuda in the context of changing climate to understand (1) the environmental setting of indigenous settlements; (2) the impacts of current coastal processes; and (3) the potential threats moving forward toward increasing pressure of climate change. Focusing on the site of Seaview, on the east coast of Barbuda, we use geoarchaeological methods to reconstruct the ancient geomorphological setting, investigate changes post-abandonment, and identify the hazards faced under future sea-level projections. Our study shows that (1) sea level stabilization after the Mid-Holocene allowed the formation of coral reefs, seagrass beds and …

Faculty, Staff, and Students

Marine heatwaves are increasingly affecting marine ecosystems, with cascading impacts on coastal economies, communities, and food systems. Studies of heatwaves provide crucial insights into potential ecosystem shifts under future climate change and put fisheries social-ecological systems through “stress tests” that expose both vulnerabilities and resilience. The 2014–16 Northeast Pacific heatwave was the strongest and longest marine heatwave on record and resulted in profound ecological changes that impacted fisheries, fisheries management, and human livelihoods. Here, we synthesize the impacts of the 2014–2016 marine heatwave on US and Canada West Coast fisheries and extract key lessons for preparing global fisheries science, management, …

Geography

Increasing fire severity and warmer, drier postfire conditions are making forests in the western United States (West) vulnerable to ecological transformation. Yet, the relative importance of and interactions between these drivers of forest change remain unresolved, particularly over upcoming decades. Here, we assess how the interactive impacts of changing climate and wildfire activity influenced conifer regeneration after 334 wildfires, using a dataset of postfire conifer regeneration from 10,230 field plots. Our findings highlight declining regeneration capacity across the West over the past four decades for the eight dominant conifer species studied. Postfire regeneration is sensitive to high-severity fire, which limits …

Daugherty Water for Food Global Institute: Faculty Publications

Long-term atmospheric CO₂ concentration records have suggested a reduction in the positive effect of warming on high-latitude carbon uptake since the 1990s. A variety of mechanisms have been proposed to explain the reduced net carbon sink of northern ecosystems with increased air temperature, including water stress on vegetation and increased respiration over recent decades. However, the lack of consistent long-term carbon flux and in situ soil moisture data has severely limited our ability to identify the mechanisms responsible for the recent reduced carbon sink strength. In this study, we used a record of nearly 100 site-years of eddy covariance …

Developing Model Federal Legislation To Advance Safe And Responsible Ocean Carbon Dioxide Removal Research In The United States, Romany M. Webb, Korey Silverman-Roati

Sabin Center for Climate Change Law

This model federal legislation aims to advance safe and responsible ocean carbon dioxide removal (CDR) research in U.S. waters. Controlled field trials and other in-ocean research is critical to improve scientific and societal understanding of CDR techniques that could help the U.S. reach its climate goals. However, existing legal frameworks were not designed to regulate ocean CDR and, in some cases, unnecessarily or inappropriately restrict needed research. The purpose of this proposed model legislation is to establish clear and efficient permitting regime for in-ocean CDR research. At the same time, the model legislation builds in consultation, monitoring, and other safeguards …

The Limits Of Portfolio Primacy, Roberto Tallarita,

Vanderbilt Law Review

According to the “portfolio primacy” theory, large asset managers, and in particular large index funds, can and will undertake the role of “climate stewards” and will push corporations to reduce their carbon footprint. This theory is based on the view that index fund portfolios mirror the entire market and therefore have strong financial incentives to reduce market-wide threats, such as climate change.

But how much can we rely on portfolio primacy to mitigate the effects of climate change? In this Article, I provide a conceptual and empirical assessment of the potential impact of portfolio primacy on climate change mitigation by …

Intersectionality & Climate Justice: A Call For Synergy In Climate Change Scholarship, Michael Mikulewicz, Martina Angela Caretta, Farhana Sultana, Neil J. W. Crawford

Geography and the Environment - All Scholarship

In this intervention, we call for extending the critical lens of intersectionality to the field of climate justice. We do so by identifying the theoretical and methodological links through which intersectionality can benefit climate change studies. These include common roots in radical theory, a focus on marginalized populations, challenging dominant epistemologies and ontologies, similar strategies for pursuing social justice, de-emphasizing of positivist methodologies, while at the same time deploying similar research methods, embracing cross-scalar and spatiotemporal analysis, and strong emphasis on interdisciplinarity and crosssectoral alliances. We conclude with a number of potential questions to inform future research on these linkages …

Responses Of Extreme Discharge To Changes In Surface-Air And Dewpoint Temperatures In Utah: Seasonality And Mechanisms, Timothy E. Wright, Jacob Stuivenvolt-Allen, Grace Affram, Nahid A. Hasan, Cody Ratterman, Wei Zhang

Plants, Soils, and Climate Faculty Publications

The changes in stream discharge extremes due to temperature and seasonality are key metrics in assessing the effects of climate change on the hydrological cycle. While scaling is commonly applied to temperature and precipitation due to the physical connections between temperature and moisture (i.e., Clausius–Clapeyron), the scaling rate of stream discharge extremes to air and dewpoint temperatures has not been evaluated. To address this challenge, we assess the scaling rates between stream discharge and air temperature and between stream discharge and dewpoint temperature in Utah using a well-designed statistical framework. While there are deviations from the Clausius–Clapeyron (CC) relationship in …

Does Bergmann’S Rule Apply To North American Birds In The Context Of Climate Change?, Peridot Derrin Galloway

Student Theses and Dissertations

Over the past half century, birds have changed, including in their morphology. Biogeographic rules including Bergmann’s and Allen’s rules have been used to try to elucidate morphological changes; however, there has been dispute over the rules’ applicability. Thus, I aimed to identify 1) morphometric trends over time of 15 North American bird species, including eastern bluebirds (Sialia sialis); 2) if these morphometric trends follow Bergmann’s rule; and 3) if the observed morphometric trends are associated with life history and other traits, as well as climatic variables (e.g., average, maximum and minimum temperatures, and total precipitation). Using short- and long-term morphological …

Optimal Stomatal Theory Predicts Co2 Responses Of Stomatal Conductance In Both Gymnosperm And Angiosperm Trees, Anna Gardner, Mingkai Jiang, David S. Ellsworth, A. Robert Mackenzie, Jeremy Pritchard, Martin Karl Friedrich Bader, Craig V.M. Barton, Carl Bernacchi, Carlo Calfapietra, Kristine Y. Crous, Mirindi Eric Dusenge, Teresa E. Gimeno, Marianne Hall, Shubhangi Lamba, Sebastian Leuzinger, Johan Uddling, Jeffrey Warren, Göran Wallin, Belinda E. Medlyn

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Optimal stomatal theory predicts that stomata operate to maximise photosynthesis (Anet) and minimise transpirational water loss to achieve optimal intrinsic water-use efficiency (iWUE). We tested whether this theory can predict stomatal responses to elevated atmospheric CO2 (eCO2), and whether it can capture differences in responsiveness among woody plant functional types (PFTs). We conducted a meta-analysis of tree studies of the effect of eCO2 on iWUE and its components Anet and stomatal conductance (gs). We compared three PFTs, using the unified stomatal optimisation (USO) model to account for confounding effects of leaf–air vapour pressure difference (D). We expected smaller gs, but …
