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. …

Effectiveness Of Municipal Collaboration For Watershed Management In The Southern Colorado River Basin, Sasha Geschwind

CGU Theses & Dissertations

There are mixed arguments about the best scale of government for providing various public goods and services. Specifically, the management of a watershed, which can be categorized as a common pool resource, is generally implemented at the local government scale via National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer Systems (MS4) permits as issued by the United States Environmental Protection Agency (US EPA). A large body of literature argues for rethinking this scale because this does not match natural watershed boundaries.In this paper, I explore the question: Does collaboration, and type of collaboration, among jurisdictions within a watershed …

Differential Impacts Of Weather Anomalies On Household Energy Expenditure Shares: A Comparison Of Clustered Panel Analysis Methods, Jordan Champion

Theses and Dissertations--Agricultural Economics

Recent emphasis on environmental justice has highlighted deficiencies in our energy system that produce disparities in accessibility and affordability for the most vulnerable. Meanwhile, the realities of a gradually warming climate and the onset of a global energy crisis (IEA 2022) have coincidently contributed to spikes in both energy prices and demand. These implications threaten to further exacerbate existing disparities for income-constrained and vulnerable populations, enhancing their risk of falling into prolonged insecurity. To ensure our transition to a just, sustainable future, we must first ensure equitable access to affordable and reliable energy for everyone. Combining household-level panel and state-level …

The Future Of International Climate Change Litigation, Heloise S. Evins-Mackenzie

Honors Theses

Small Island Developing States (SIDS) are increasingly seeking justice from international courts to address their significant climate change impacts, which are disproportionate to their minimal historical emissions. The Commission of Small Island States on Climate Change and International Law (COSIS), an internationally recognized legal body, has requested an advisory opinion on the obligations of all member states to protect and preserve the marine environment and prevent pollution related to climate change and its impacts. The present study aims to predict the future landscape of climate litigation if the International Tribunal for the Law of the Sea (ITLOS) specifies that states’ …

Impact Of Solar Radiation On Perchlorate Formation In The Atmosphere: Evidence From Ice Core Measurements, Bishnu Kunwar

Electronic Theses and Dissertations

Perchlorate, which derives from both anthropogenic and natural sources in the current environment, poses a substantial health hazard to humans as it competes with iodine uptake in the thyroid gland. Consequently, there has been considerable concern about minimizing human exposure to environmental perchlorate by restricting its release from man-made sources. However, the absence of a clear understanding regarding the respective contributions of man-made and natural sources has hindered widespread regulation efforts. A 300-year (1700–2007) Summit, Greenland ice core record from a previous study showed relatively stable perchlorate concentrations in Greenland snow prior to 1980, with some elevated perchlorate levels associated …

The Effects Of Temperature, Flooding, And Goose Feces Addition On Greenhouse Gas Emissions And Ammonification In Four High-Latitude Soils From Western Alaska, Jenna M. Ross

Electronic Theses and Dissertations

The large carbon (C) stock of wetlands is vulnerable to climate change, especially in high latitudes that are warming at a disproportional rate. Likewise, low-elevation Arctic coastal areas will flood more frequently under climate change and sea-level rise, which may alter goose herbivory and fecal deposition patterns if geese move inland. While temperature, flooding, and feces impact soil C emissions, their interactive effects have been rarely studied. Here, I explore the impact of these interactions on CO2 and CH4 emissions and nitrogen (N) mineralization (ammonification) in soils collected from four plant communities in the Yukon-Kuskokwim (Y-K) Delta, a high latitude …

Effects Of El Nino And Sunspot Cycles On Global And Reginal Climate, August Nathan Tolzman

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Sunspots and El Nino affect the interannual variability of temperature on earth. Separately there is a positive relationship between higher sunspots and warmer temperatures or more intense El Nino and warmer temperatures globally and in Missoula. This is with the bias of climate change removed. Putting these two processes together it is expected that when intense El Ninos and high sunspots happen in the same year there will be warmer temperatures. This was not the case, there was no data to support that putting these to processes together makes them more or less intense.

Improving Accessibility And Understanding: Studying The Impact Of Human Activities And Dam Removals On Anadromous Fish Species In The Pacific Northwest, Adia F. Bennett

Scripps Senior Theses

Human activities in North American watersheds have significantly impacted anadromous fish, causing some species of salmon and steelhead to become threatened and endangered. These fish hold ecological, cultural, and economic importance, yet factors such as habitat destruction, overfishing, pollution, climate change, and hydroelectric dams continue to degrade populations. Dams are particularly harmful to anadromous fish, sparking a recent movement advocating for dam removals. This study uses NOAA’s 2022 Biological Viability Assessment to examine the response of anadromous fish to recent dam removals in the Pacific Northwest. Four populations were selected to analyze due to their interaction with sites that had …

The Role Of Atmospheric And Oceanic Feedbacks In Orbital And Millennial Timescale Variability Of The Coupled Climate-Carbon System, Fangze Zhu

Legacy Theses & Dissertations (2009 - 2024)

An intriguing mechanism of the Pleistocene glacial-interglacial cycles is the phase locking of internal climate oscillations to external forcings, suggesting the leading role of the natural climate variability in the past climate changes on orbital timescales. Similarly, the millennial-scale variability over the last glacial period may be attributed to unforced climate dynamics. One of the central themes of the climate sciences is to acquire a fundamental understanding of climate feedbacks over a broad range of timescales. The main objective of this thesis is to identify the characteristic natural variability in a fully coupled climate-carbon model from orbital to millennial timescales, …

Removing Development Incentives In Risky Areas Promotes Climate Adaptation, Hannah Druckenmiller, Yanjun (Penny) Liao, Sophie Pesek, Margaret Walls, Shan Zhang

Economics Faculty Publications

As natural disasters grow in frequency and intensity with climate change, limiting the populations and properties in harm’s way will be key to adaptation. This study evaluates one approach to discouraging development in risky areas—eliminating public incentives for development, such as infrastructure investments, disaster assistance and federal flood insurance. Using machine learning and matching techniques, we examine the Coastal Barrier Resources System (CBRS), a set of lands where these federal incentives have been removed. We find that the policy leads to lower development densities inside designated areas, increases development in neighbouring areas, reduces flood damages and alters local demographics. Our …

Burning Fear, Amy Dorie

Textile Society of America: Symposium Proceedings

Climate change is leading to more intense and devastating wildfires that lead to tragic loss of life and property (Cal Fire, 2018; Sinco et al., 2023) and disturbing environmental impacts (OECD, 2023). The purpose of this textile design was to create an activist design that communicates the fear and anxiety felt by those impacted by wildfires. First-hand accounts of those experiencing wildfires were researched as inspiration for the textile design. Based on the accounts, a selection of wildfire-related images were cropped in irregular shapes, placed around the canvas, and blended evoking a sense of chaos and devastation. An image of …

Determining The 2022-2023 Mass Balance Of The Palisade Glacier In The Sierra Nevada Mountains Of California With Remote Sensing, Density Modeling, And Temperature-Index Techniques, Vijay Jain, Eric Grosfils, Sarah Kavassalis

CMC Senior Theses

Small, alpine glaciers, such as those in the Sierra Nevada, are difficult to study because of their small size and remoteness, however, they are important recorders of the impacts of climate change in temperate, alpine environments. Previous studies have attempted to characterize the health of these glaciers using extent change techniques, but these methodologies can only roughly approximate the rudimentary measurement of changing ice volume. This thesis uses the Airborne Snow Observatory Inc.’s (ASO’s) aerial lidar snow depth datasets to perform a mass balance calculation for the Palisade Glacier over the remarkable 2022-2023 water year (October 1 through September 30), …

C. Compactum Acts As A Comprehensive Climate Archive And Ecological Foundation In The Labrador Sea, Sadie Heckman

CMC Senior Theses

Clathromorphum compactum, a species of crustose coralline algae (CCA), is incredibly valuable for the future of high latitude ocean health, both as a comprehensive archive of changing ocean conditions, and ecologically as a foundational species for promoting biodiversity. Previous work establishes C. compactum as an effective climate proxy, and its life history provides several advantages for this use. C. compactum grow in nongeniculate, generally radial formations on hard substrates, over a wide distribution in mid-to-high latitude oceans and at subtidal depth ranges. Indeterminate growth leads to extreme longevity in C. compactum (Halfar et al., 2008), and growth rates are relatively …

It Is Normal: The Probability Distribution Of Temperature Extremes, Nir Y. Krakauer

Publications and Research

The probability of heat extremes is often estimated using the non-stationary generalized extreme value distribution (GEVD) applied to time series of annual maximum temperature. Here, this practice was assessed using a global sample of temperature time series, from reanalysis (both at the grid point and the region scale) as well as station observations. This assessment used forecast negative log-likelihood as the main performance measure, which is particularly sensitive to the most extreme heat waves. It was found that the computationally simpler normal distribution outperforms the GEVD in providing probabilistic year-ahead forecasts of temperature extremes. Given these findings, it is suggested …

Exploring Women`S Perceptions Of Climate Change Impact On Agriculture, Health & Food Security In Upper Hunza, Gilgit Baltistan, Ambreen, Elina Nizar Ali, Taiba Yar Baig, Fozia Parveen

Institute for Educational Development, Karachi

The Hindu Kush Himalayan (HKH) region, renowned for its towering mountains and major river basins, sustains nearly 1.4 billion people worldwide and is pivotal to global food production. Glacial melt from the HKH region nourishes agriculture, livestock, and horticulture, supporting the livelihoods of mountain communities. However, climate change is accelerating the melting of glaciers, and shifts in wet seasons significantly impact food security in these communities. Sectors such as water resources, agricultural land, and human health, particularly women’s health, are significantly affected by these changes. For centuries, agriculture has been the backbone of Gilgit-Baltistan’s economy, with over 70% of livelihoods …

Antarctic Polar Stratospheric Cloud Analysis Of Ace-Fts Data From 2005 To 2023, M. Lecours, C. D. Boone, P. F. Bernath

Chemistry & Biochemistry Faculty Publications

We present an analysis of Antarctic polar winters from 2005 to 2023 as observed by the Atmospheric Chemistry Experiment (ACE). The unique broad band infrared spectral features in ACE “residual” spectra are used to classify the spectra of polar aerosols by composition into polar stratospheric clouds (PSCs) and sulfate aerosols. The spectra of PSCs are further classified into nitric acid trihydrate, supercooled ternary solutions, supercooled nitric acid, ice-mix, and mixtures of PSCs. A breakdown of PSC composition is presented for each year. Antarctic winter seasons with unusual compositions are: 2011, in which volcanic ash mixed with PSCs was observed from …

Communicating Climate Change: Adaptive Silviculture In Central Appalachian Kentucky, Logan Baker

Theses and Dissertations--Forestry and Natural Resources

Climate change communication is an emerging field that requires a multidisciplinary understanding of both climate and social science. Communicating with underrepresented woodland owners about climate change, specifically climate change adaptation in forestry applications, necessitates appropriately adjusted approaches. In Central Appalachian Kentucky, outreach with underrepresented woodland owners on forest adaptation topics has not been examined in depth. The recent establishment of an Adaptive Silviculture for Climate Change research site in the University of Kentucky’s Robinson Forest has created an opportunity to generate regionally specific climate adaptation information for Appalachian Kentucky forests. It is imperative to investigate how best to approach communicating …
