Using Repeat Photography To Document The Effects Of Climate Change On Glaciers In Iceland Change On Glaciers In Iceland, Madeleine Gassin

Environmental Studies Honors Papers

Climate change is a worldwide, multifaceted phenomenon that impacts our world today and will continue to impact our world in the future with even greater severity. Although climate change can sometimes be considered an abstract topic due to its being somewhat intangible, one direct way of observing the effects of climate change is by studying glaciers. This study combines a literature review with repeat photography in order to demonstrate the tangible effects of climate change on glaciers in Iceland and explore the secondary impacts on sea level elevation (SEL), water availability and distribution, hydropower, natural hazards, and tourism in Iceland. …

Deep Learning Approaches For Chaotic Dynamics And High-Resolution Weather Simulations In The Us Midwest, Vlada Volyanskaya, Kabir Batra, Shubham Shrivastava

Discovery Undergraduate Interdisciplinary Research Internship

Weather prediction is indispensable across various sectors, from agriculture to disaster forecasting, deeply influencing daily life and work. Recent advancement of AI foundation models for weather and climate predictions makes it possible to perform a large number of predictions in reasonable time to support timesensitive policy- and decision-making. However, the uncertainty quantification, validation, and attribution of these models have not been well explored, and the lack of knowledge can eventually hinder the improvement of their prediction accuracy and precision. Our project is embarking on a two-fold approach leveraging deep learning techniques (LSTM and Transformer) architectures. Firstly, we model the Lorenz …

Enhancing Our Understanding Of Ancient Oceans Through The Investigation Of Molybdenum Behavior Under Sulfidic Conditions, Rachel Faye Phillips

Open Access Theses & Dissertations

The most abundant trace metal in the ocean today, molybdenum (Mo), exhibits distinct behavior in oxygenated water, where it remains predominantly dissolved, compared to euxinic (i.e., oxygen-free and sulfidic) water, in which it is sequestered into the sediment. This dissimilar behavior allows us to use Mo concentrations and isotopic compositions in sediment to reconstruct marine oxygenation conditions throughout geologic history. However, Mo sequestration mechanisms under euxinic conditions remain unresolved, which limits the accuracy and precision of reconstructions made using Mo signatures in the rock record. For my doctoral research, I experimentally investigated abiotic and biotic Mo sequestration mechanisms under various …

Reducing Inputs And Adding Value To Turfgrass Systems Through Clover Inclusion And Plant Growth-Promoting Rhizobacteria Applications, Paige E. Boyle

All Graduate Theses and Dissertations, Fall 2023 to Present

Recently, the US has seen an expansion in the amount of turfgrass land cover (lawns, parks, roadsides, sports fields, and golf courses), as well as an interest in reducing fertilizer, water, and pesticide use in these grass systems. To help maintain quality and function while reducing resource inputs, two promising approaches have emerged: planting clover into lawns and applying plant growth-promoting rhizobacteria.

White clover and grass mixtures have been studied for their ability to cut down on fertilizer usage and provide a uniform, dark green lawn, but other clover types have not been as widely studied and may provide similar …

Ecology And Management Of Dyer's Woad (Isatis Tinctoria) In Northern Utah, Erin Marie Hettinger

All Graduate Theses and Dissertations, Fall 2023 to Present

Dyer’s woad (Isatis tinctoria L.) is a non-native forb that continues to threaten natural areas throughout Northern Utah and much of the Intermountain West. Once introduced, dyer’s woad can become extremely invasive, decreasing forage quality, and displacing native species. While dyer’s woad is found throughout much of Northern Utah, its range in other states remains limited. If promptly managed, control success in these areas will be much higher and populations may be kept at bay before ecological damage becomes severe.

This project tested the ability of dyer’s woad seedlings to compete with common rangeland grasslands at varied densities as …

The Tidal Prism, Viable Eelgrass Habitat, And The Effects Of Sea Level Rise In Morro Bay, Kaden A. Caliendo

Master's Theses

The tidal prism, or the volume of water exchanged from the sea to an estuary from mean low to mean high tide, influences system hydrodynamics and ecological functioning. Since 1884, the tidal prism in Morro Bay, California has been estimated to be decreasing over time due to sedimentation from upstream practices. What is the current tidal prism in Morro Bay and how will that change with sea level rise? How will eelgrass respond to rising sea levels?

For this study, inexpensive tidal gauges were deployed at four locations in Morro Bay from March to August 2023 to measure spatially varying …

Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy

Symposium of Student Scholars

Jobos Bay Estuary is an intertidal, tropical estuary located in southern Puerto Rico. The estuary covers about 12 km² and has a variety of habitats, such as seagrass beds, mangroves, mud flats, and coral reefs, which play important roles in sediment trapping and water quality maintenance. Seagrasses also serve as nursery and feeding grounds and provide shelter for macrofauna. Currently, the role of seagrasses and water quality on nitrogen (N) cycling in trophic estuaries is not well constrained. Understanding variations in sediment-based effects on N cycling rates and transformations, and how they are associated with water quality, is an …

After a review of the history and science behind visual storytelling, she analyses one of the graphic recordings made for the third meeting of the Technical Dialogue of the Global Stocktake through the lens of Kelvy Bird’s ‘Levels of Scribing’ model. Drawing on comments from delegates at COP27 in Sharm el-Sheikh, Egypt and …

The Role Of Carbon Management Technologies In Meeting Net Zero, Ali Al-Saffar

New England Journal of Public Policy

The pathway toward implementing the changes necessary in the energy sector to keep global temperature rises from breaking through catastrophic barriers is narrow and tenuous and will require a range of zero- and low-carbon technologies to be dispatched at a speed and scale that is virtually unprecedented. Decarbonization through renewables, matched with the more efficient use of energy in the end-use sectors will play a large part. But there is growing realization that there will be residual fossil fuel use long into the future, and that the emissions from the burning of these fossil fuels in power plants and factories …

The Gulf: An Appeal For More Coordinated Action On Climate Change, Fareed Yasseen

New England Journal of Public Policy

This article seeks to provide the rationale behind Iraqi Prime Minister Al-Sudani’s call at the United Nations for the formation of a negotiating group within the United Nations Framework Convention on Climate Change process that brings together all member states of the Gulf Cooperation Council, Iraq, and Iran. This article argues that these countries would benefit doubly from such an arrangement, because it would help them better address the direct effects of climate change, on the one hand, and to better address the effects of the measures taken to address climate change, which will affect them as fossil fuel producers, …

Results Of Cop27 And Expectations For Cop28, Cecilia Kinuthia-Njenga, Fareed Yasseen

New England Journal of Public Policy

Since 1995, government representatives from around the world have gathered nearly every year for the United Nations Conference of the Parties (COP) to advance work on multilateral agreements and to provide a way forward in tackling the significant challenges of climate change. The last of these conferences took place on November 6–20, 2022, in Sharm el-Sheikh, Egypt.

COP27 brought together more than 35,000 people from across the globe to deliberate on important actions for addressing the climate. Hailed as the “African COP” and “Implementation COP,” it raised expectations that decisions from previous conferences, reflecting the needs and priorities of the …

The Perfect Is The Enemy Of The Good: Carbon Credits And Funding For Decarbonization In Developing Countries, Andrew A. Bernstein

New England Journal of Public Policy

Carbon credits issued in the voluntary carbon market are an important source of funding for projects in developing countries designed to reduce greenhouse gas emissions, such as forest preservation and renewable energy. Beyond their potential to provide billions of dollars of private sector financing for decarbonization, carbon credits can generate economic opportunity, employment, and biodiversity. But they are controversial, mainly (but not only) because it is difficult to confirm and to quantify their emissions benefits. This article argues that policymakers should nonetheless support voluntary carbon market growth, so long as companies use carbon credits to mitigate emissions they cannot avoid …

Joint Global Responsibility Fund For Climate, Conservation, And Communities: A Proposed Innovative Tax-Based Funding Mechanism, Tamar Ron

New England Journal of Public Policy

Nature-based solutions address biodiversity loss, climate change, and societal challenges at the local, national, regional, and global levels. The costs of their conservation, however, are mostly local and national in nature. Confronting the rolling dual crisis of biodiversity loss and climate change requires us to recognize nature’s intrinsic value. Moreover, we must find practical ways for their monetary valuation to be channeled as payment for the services of conservation custodians. It is suggested here to translate the value of natural assets and the understanding of the local costs and global benefits of their conservation, into an innovative and ambitious funding …

Solar Radiation Modification Governance In The Context Of Temperature Overshoot, Janos Pasztor

New England Journal of Public Policy

As the climate crisis escalates, governments—and recently even those in the wealthier countries in the Global North—are struggling to manage the impacts we are experiencing around the world in frightening abundance, including record-setting temperatures, fires, floods, and glacial and ice melt. Behind closed doors, policymakers are concerned as they contemplate the increasing likelihood, even under the most ambitious emission reduction pathways, that the world will overshoot the goal agreed upon in the Paris Agreement to limit global average temperature rise to 1.5oC beyond pre-industrial levels.

It is in this “overshoot context” that interest is growing in an emerging, potentially supplementary …

Cop27 And The New Rise Of The Global South, Janice Golding

New England Journal of Public Policy

Developing countries require direct and indirect financial and non-financial assistance to address the climate crisis. The COP27 announcement of a new Loss and Damage Fund as well the unveiling of the Bridgetown Initiative collectively hold substantial promise to alter the course of climate multilateralism. The outcome of COP27 has presented unprecedented opportunities for the Global South to build global solidarity for climate justice, but the path ahead will not be easy. Materialization of support to developing countries may be, at best, not sustainable, or at worst, unforeseeable without consistent application of principles and values enshrined in historic, moral accountability for …

Translation Speed Influence On Tropical Cyclone Storm Tide And Surge Generation Along The Gulf Of Mexico Coast, Samantha L. Camarda

LSU Master's Theses

This research examines tropical cyclone translation speed as a factor in storm tide and surge height upon landfall on the United States Gulf Coast. Understanding the effect of translation speed on peak storm tide/surge height is needed to better prepare for and predict future damage from tropical cyclone events. Tropical cyclone data are taken from hourly interpolated best-track HURDAT2 data from 1970–2021. This study uses the HURDAT2 hourly interpolated observation data points (24-hours) pre-landfall to landfall. Translation speed is calculated based on the distance traversed between hourly points. Peak storm tide and storm surge data are taken from SURGEDAT from …

A Climatology Of Mesoscale Airmasses With High Theta-E, Charles J. Kropiewnicki

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

A Mesoscale Airmass with High Theta-E (MAHTE) is a narrow region of larger theta-e located on the cool side of an airmass boundary. MAHTEs typically possesses higher CAPE than the warm side of the boundary, creating a more favorable environment for severe convection. MAHTEs can also be characterized by larger low-level shear and lower LCLs and may also have a propensity for supporting tornadogenesis. The majority of MAHTE research to date has been comprised of case studies, and the prevalence of MAHTEs is not well understood. This project fills that knowledge gap by creating a climatology of MAHTE occurrence. This …
