Trends In Drought Over The Northeast United States, Nir Y. Krakauer, Tarendra Lakhankar, Damien Hudson

Publications and Research

The Northeast United States is a generally wet region that has had substantial increases in mean precipitation over the past decades, but also experiences damaging droughts. We evaluated drought frequency, intensity, and duration trends in the region over the period 1901–2015. We used a dataset of Standardized Precipitation Evapotranspiration Index (SPEI), a measure of water balance based on meteorology that is computed at multiple timescales. It was found that the frequency of droughts decreased over this period, but their average intensity and duration did not show consistent changes. There was an increase in mean SPEI, indicating mostly wetter conditions, but …

Rock Glaciers Of The Beartooth And Northern Absaroka Ranges, Montana, Usa, Zachary M. Seligman, Anna E. Klene, Frederick E. Nelson

Geography Faculty Publications

Six hundred sixty‐one rock glaciers in the northern Absaroka and Beartooth Ranges of south‐central Montana were digitized and evaluated using geographic information systems technology and an array of topographic and environmental parameters. Beartooth rock glaciers are larger, occur at higher elevations, receive more precipitation, and are subject to lower temperatures than northern Absaroka rock glaciers. Elevation is strongly correlated with rock glacier activity. Comparative analysis of these adjacent mountain ranges indicates that Beartooth geomorphic landscapes are shifting from predominantly glacial to periglacial regimes, and that the northern Absarokas have largely completed this transition. Because glaciers are declining in response to …

Examination Of Human Health Impacts Due To Adverse Climate Events Through The Use Of Vulnerability Mapping: A Scoping Review, Michael T. Schmeltz, Peter J. Marcotullio

Publications and Research

Government officials, health professionals, and other decision makers are tasked with characterizing vulnerability and understanding how populations experience risks associated with exposure to climate-related hazards. Spatial analyses of vulnerable locations have given rise to climate change vulnerability mapping. While not a new concept, the spatial analyses of specific health outcomes remain limited. This review explores different methodologies and data that are used to assess vulnerability and map population health impacts to climate hazards. The review retrieved scholarly articles and governmental reports concerning vulnerability mapping of human health to the impacts of climate change in the United States, published in the …

The Missing Angle: Ecosystem Consequences Of Phenological Mismatch, Karen H. Beard, Katharine C. Kelsey, A. Joshua Leffler, Jeffrey M. Welker

Ecology Center Publications

Climate change leads to unequal shifts in the phenology of interacting species, such as consumers and their resources, leading to potential phenological mismatches. While studies have investigated how phenological mismatch affects wild populations, we still lack studies and a framework for investigating how phenological mismatch affects ecosystems, particularly nutrient cycling.

Collective Survival Strategies And Anti-Colonial Practice In Ecosocial Work, Finn Mclafferty Bell, Mary Kate Dennis, Amy Krings

Social Work: School of Social Work Faculty Publications and Other Works

Oppressed communities have long used strategies of caring for and protecting each other to ensure their collective survival. We argue for ecosocial workers to critically interrogate how agency, history, and culture structure environmental problems and our responses to them, by developing a resilience-based framework, collective survival strategies (CSS). CSS consider power, culture and history and build upon the strengths of oppressed communities facing global environmental changes. We challenge the dominant narrative of climate change as a “new” problem and connect it to colonization. We discuss implications by examining a social work program explicitly built on Indigenous knowledges and anti-colonial practice.

Predicting Pelargonium Responses To Climate Change In A Biodiversity Hotspot Throughout South Africa, Tanisha Marie Williams

Doctoral Dissertations

Climate change is causing major shifts in species distributions, which fundamentally alters the species composition and functioning of biological communities across the globe. Projections suggest that by 2100 up to one of every six species will become extinct. Such drastic changes will have significant impacts on biodiversity patterns and ecosystem functioning. Ecologists are faced with the pressing work of trying to understand how plants will respond to changing and increasingly stressful environments. To predict the long-term effects and magnitude of species responses, it is imperative that species adaptive responses are understood across the entirety of their geographic ranges. My dissertation …

The Vulnerability Of Littoral Structures Under Multiyear Drought Conditions, Jenna M. Keeton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change is associated with altered environmental conditions and shifting mosaics of suitable habitats for organisms. Climate change in the form of drought can shift important lake shoreline habitats downslope, altering the lakes chemistry and habitat availability. Additionally, negative biological consequences can occur after a loss of submerged habitat along shorelines, hereafter littoral habitat. The objective of this study is to evaluate whether littoral habitat is lost (cobble, coarse woody habitat (fallen trees; CWH), and aquatic vegetation) under drought conditions across the United States. I used the National Lakes Assessment physical habitat data collected in summer 2012, when 75% of …

Main And Interactive Effects Of Increased Precipitation And Nitrogen Addition On Growth, Morphology, And Nutrition Of Cinnamomum Burmanni Seedlings In A Tropical Forest, Jun Wang, Dafeng Hui, Hongfang Lu, Faming Wang, Nan Liu, Zhongyu Sun, Hai Ren

Biology Faculty Research

Global change such as altered precipitation patterns and increased atmospheric nitrogen (N) deposition will have significant impacts on seedling growth during plant recruitment. However, how interactive effects of increased precipitation and N deposition on forest seedling performance have not been well investigated. In this study, we conducted a two-year field experiment that manipulating precipitation amount (ambient rainfall and 25% increment during the wet season) and exogenous N addition (0 and 100 kg ha−1 yr−1) in a tropical secondary forest. Seedling growth, morphology and nutritional status of a dominant tree species (Cinnamomum burmanni) were measured. Results showed that increased precipitation had …

Evaluating Tree Species' Migration Potential Using Latitudinal Tree Growth Rate Across The Eastern United States, Michelle Marie Field

Electronic Theses and Dissertations Archive

Predicting climate-driven tree species’ future redistribution is a key element to guide preemptive forest management to mitigate the adverse consequences of climate change. This study uses the Forest Inventory and Analysis (FIA) database to determine tree species’ potential. The dynamic variable calculated in the study is the standardized growth rate residual by basal area for a ten-year period (2003-2013). Residuals of growth rate are examined by latitude within each species’ range, indicating on-going habitat preference. This study examined six, US confined species that are climate sensitive. While this study hypothesized that high growth rate residuals would be present at northern …

Thousands Forced To Migrate As Sea Swallows Coastal Belt, Jahanzeb Tahir

MSJ Capstone Projects

Pakistan is one those tropical countries that faces a major climate change challenge. People are generally less concerned about the issue but a great effort is required to face this growing threat. Extreme weather events can already be seen. In 2015 more than 2000 people died because of heat wave which heat in Karachi, the capital of Sindh province.

Karachi, the Arabian coastal region has area of approximately 3,640 km2. The impact of global warming can be measured in the coastal region as sea levels have risen by approximately 10 centimetres in the last century. The sea levels are expected …

Avoiding Maladaptations To Flooding And Erosion: A Case Study Of Alaska Native Villages, Elizaveta Barrett Ristroph

Ocean and Coastal Law Journal

This article offers perspective on how Alaska Native Villages (ANVs), which are small and rural indigenous communities, are adapting to changes in flooding and erosion. It considers which adaptations might be maladaptations and what might be done to facilitate adaptation short of relocating entire communities. It outlines the United States' legal framework applicable to flooding and erosion and considers why this framework may do little to assist ANVs and similarly situated small and rural communities. Findings regarding adaptation strategies and obstacles are drawn from my Ph.D. research, which involved a review of plans for fifty nine ANVs and 153 interviews …

Attendance Trends Threaten Future Operations Of America’S State Park Systems, Jordan Smith, Emily J. Wilkins, Yu-Fai Leung

Environment and Society Faculty Publications

This research examines how the operating expenditures of America’s state park systems will be affected by a continued growth in attendance consistent with observed trends as well as potential climate futures. We construct a longitudinal panel dataset (1984–2017) describing the operations and characteristics of all 50 state park systems. These data are analyzed with a time-varying stochastic frontier model. Estimates from the model are used to forecast operating expenditures to midcentury under four different scenarios. The first scenario assumes annual attendance within each state park system will continue to grow (or decline) at the same average annual rate that it …

Role Of Recent Climate Change On Carbon Sequestration In Peatland Systems., Paul H. Lunt, Ralph M. Fyfe, Alan D. Tappin

School of Geography, Earth and Environmental Sciences

This paper provides information on the impact of recent climate change on carbon sequestration in peatland systems in South West England. This is important because peatlands have the potential to sequester and hold large quantities of anthropogenically released CO2. This paper investigates whether there has been a reduction in the strength of carbon sinks in a valley mire and blanket bog, which occur on the limits of the biogeographical envelop for peatlands in Britain. Past rates of carbon accumulation were calculated from peat depth and the sequential analysis of peat age, bulk density and carbon content from cores taken from …

Fallen Pillars: The Past, Present, And Future Population Dynamics Of A Rare, Specialist Coral–Algal Symbiosis, Andrea Chan, Cynthia L. Lewis, Karen L. Neely, Iliana B. Baums

Marine & Environmental Sciences Faculty Articles

With ongoing changes in climate, rare and ecologically specialized species are at increased risk of extinction. In sessile foundation fauna that reproduce asexually via fragmentation of existing colonies, the number of colonies does not reflect the number of genets and thus can obscure genotypic diversity. Colonies that are the product of fragmentation are not visually distinguishable from colonies that stem from sexual recruits. For this reason, molecular markers are necessary to assess genotypic variation and population structure in clonal organisms such as reef-building corals and their endosymbiotic dinoflagellates. For the rare Caribbean pillar coral, Dendrogyra cylindrus, and its endosymbiotic …

Nordic And American Social Capital And Its Effects On Climate Change Adaptation, Lara Heard

Senior Theses

The Nordic nations often rank among the most climate-prepared countries in the world, especially in regards to their rapid switch to renewable energy. In contrast, climate change legislation has faced an uphill battle in the United States, where environmentalists and activists meet with climate change denialism and widespread reluctance to change energy consumption habits. This thesis argues that the gap between American and Nordic adaptation arises in large part from difference in social capital. I n the United States, a recent decline in social trust and increase in individualism endanger adaptation efforts, creating a culture of consumerism and widespread reluctance …

Connecticut Waterfront Property Premium In Areas With Flood Risk, Conor O'Donnell

Honors Scholar Theses

This paper investigates the premium paid for waterfront property along the Connecticut shoreline and how that premium is affected by its vulnerability to coastal flooding as measured by its location relative to the FEMA 100-year and 500-year flood zones. The primary analysis is a comparison of the rate of appreciation of properties within each flood zone relative to coastal properties outside the flood-zone. An analysis of the impact of Super Storm Sandy in 2012 on the appreciation rate is also presented. It is hypothesized that the rate of appreciation of properties within the 100-year flood zone is lower following Hurricane …

United States National Park Service: Publications

Rock ptarmigan (Lagopus muta) and willow ptarmigan (L. lagopus) are Arctic birds with a circumpolar distribution but there is limited knowledge about their status and trends across their circumpolar distribution. Here, we compiled information from 90 ptarmigan study sites from 7 Arctic countries, where almost half of the sites are still monitored. Rock ptarmigan showed an overall negative trend on Iceland and Greenland, while Svalbard and Newfoundland had positive trends, and no significant trends in Alaska. For willow ptarmigan, there was a negative trend in mid-Sweden and eastern Russia, while northern Fennoscandia, North America and Newfoundland had no significant trends. …

The (Next) Big Short And The End Of The Anthropocene, M. Alexander Pearl

Utah Law Review

It is incredibly difficult to imagine an event the likes of which humans have never seen before. That, in and of itself, renders the challenge to prepare for such an event even more difficult because there is no frame of reference pushing us to act. How do you prepare to avoid something which has never occurred in the history of human occupation? That is the challenge of climate change.

I argue that the Subprime Mortgage Crisis and its aftermath parallel the Climate Crisis in critical ways that should inform our tactics. Of course, there are obvious critical differences as well. …

An Examination Of Seasonal Shifts In Climate And Visitation, And Perspectives On Seasonal Shifts And Climate Adaptation Strategies In Tourism And Recreation Businesses For Moab, Utah, Elizabeth Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The city of Moab, an outdoor recreation hub in eastern Utah, has been encountering both shifts in the seasonality of visitation, and increases in tourist visitation, even with summer temperatures above the normal high. Tourism research describing the effects of climate change on the outdoor recreation industry has focused on winter, snow-dependent activities, while studies in Moab city have focused on the economic value of outdoor recreational activities. Few studies have described the relationship between seasonal tourism and climate change for arid desert locations. The purpose of this study is to describe how the tourism and recreation industry in Moab, …

Assessment Of Barrier Island Restoration Planning And Management In The Terrebonne Basin, Louisiana, Sean Russell Williams

LSU Master's Theses

Louisiana holds the majority of the contiguous United States’ coastal wetlands by area, providing significant benefits to users in the form of ecosystem services. Climate change, relative sea level rise, and coastal sediment budget deficits among other anthropogenic processes impact the resilience and sustainability of Louisiana’s coastal systems. Since the implementation of the Coastal Wetland Planning, Protection and Restoration Act (CWPPRA) to restore coastal wetlands in the United States, multiple barrier island restoration projects have taken place in the greater Terrebonne Basin. Amassing a catalog of case studies elucidates the social, ecological, and economic frameworks behind barrier island restoration and …

Adjudication And The Adaptive Capacity Of Pecan Farmers In The Lower Rio Grande, Daniel R. Beene

Geography ETDs

Despite growing uncertainty of water availability in the future and popular understandings of water conservation in agriculture, a growing number of farmers in the Lower Rio Grande Basin are rapidly transitioning to pecan orchards, a long-term and highly water-dependent crop. Drivers of landscape change can be environmental, historic, socioeconomic, or institutional. Adaptation to change is understood as responses to external stimuli and is limited to a threshold by which an actor can meet their goals. Much of the current scholarship focuses on a given population’s adaptive capacity toward global climate change, however, most water policy in the western United States …

“In Principle” Versus “In Reality”: Assessing The Potential Of Adaptive Urban Governance Toward Urban Flooding In Ho Chi Minh City’S District 7, Cindy Pham Nguyen

Independent Study Project (ISP) Collection

Flooding has become the new normal in Ho Chi Minh City (HCMC). During the rainy season, many areas of the city experience severe inundation that seriously impacts infrastructure, traffic, and economic transactions. As the effects of climate change unpredictably and rapidly manifest in Southern Vietnam, the frequency and impact of urban floods are projected to increase. In addition, within the last few decades, HCMC has rapidly developed and urbanized, transforming itself into the economic center of Southern Vietnam. However, previous studies and international experts have determined that rapid, poor development may be exacerbating urban flood issues.

In recent years, city …

Effects Of Increased Precipitation On The Life History Of Spring- And Autumn-Germinated Plants Of The Cold Desert Annual Erodium Oxyrhynchum (Geraniaceae), Yanfeng Chen, Xiang Shi, Lingwei Zhang, Jerry M. Baskin, Carol C. Baskin, Huiliang Liu, Daoyuan Zhang

Biology Faculty Publications

Future increased precipitation in cold desert ecosystems may impact annual/ephemeral plant species that germinate in both spring and autumn. Our primary aim was to compare the life history characteristics of plants from spring-germinating (SG) and autumn-germinating (AG) seeds of Erodium oxyrhynchum. Plants in field plots with simulated increases in precipitation of 0, 30 and 50 % in spring and summer were monitored to determine seedling survival, phenology, plant size, seed production and biomass accumulation and allocation. Germination characteristics were determined in the laboratory for seeds produced by plants in all increased precipitation treatments. Increased precipitation in spring significantly improved survival …

Precipitation Trends Across The Commonwealth Of Virginia (1947 – 2016), Michael J. Allen, Thomas R. Allen

Virginia Journal of Science

Water is an important resource for the Commonwealth of Virginia. Too much water increases runoff, disrupt transportation networks, and contributes to school closures. Too little water may adversely impact agricultural operations. To improve climate-related information to Virginia citizens, this study assesses means and changes in precipitation across the Commonwealth of Virginia (1947 – 2016). Using daily station-level precipitation data from the Global Historical Climate Network (GHCN), descriptive statistics were calculated for 43 locations in terms of total precipitation (inches decade^-1), precipitation days (x>0”), and heavy precipitation days (x>1.0”). On average, locations showed an overall increase in …
