Flood Realities, Perceptions, And The Depth Of Divisions On Climate, Lawrence C. Hamilton, Cameron P. Wake, Joel N. Hartter, Thomas G. Safford, Alli J. Puchlopek

Sociology

Research has led to broad agreement among scientists that anthropogenic climate change is happening now and likely to worsen. In contrast to scientific agreement, US public views remain deeply divided, largely along ideological lines. Science communication has been neutralised in some arenas by intense counter-messaging, but as adverse climate impacts become manifest they might intervene more persuasively in local perceptions. We look for evidence of this occurring with regard to realities and perceptions of flooding in the northeastern US state of New Hampshire. Although precipitation and flood damage have increased, with ample news coverage, most residents do not see a …

Using Photovoice To Understand Climate Change Adaptation In Rural Ontario, Kylie Hissa

Geography and Environmental Studies Major Research Papers

The examination of community adaptation and resilience approaches to address the threats of climate change in rural Ontario is becoming increasingly important in emergency management and preparedness. Community engagement becomes critical in this regard, as local experiences partly influence perceptions of climate change risks within municipalities. Photovoice is a community-based participatory research methodology that empowers participants to document their perceptions and understandings of a particular issue through the use of visual images. This technique was undertaken to understand the impacts of the F3 tornado that hit the community of Goderich, Ontario in 2011 and capture their member’s perceptions on disaster …

Irrigation Technology Choice As Adaptation To Climate Change In The Western United States, George Frisvold, Ting Bai

Journal of Contemporary Water Research and Education

Several commentators have suggested adoption of improved irrigation will be important for agricultural adaptation to climate change. This study used data from a special tabulation of the United States Department of Agriculture (USDA) Farm and Ranch Irrigation Survey to examine how climate and other factors influence the choice of sprinkler versus gravity-flow irrigation across 17 western states. Because studies of irrigation technology adoption often concentrate on small geographic areas with the same climate, few have estimated effects of climate on irrigation technology choice. Results suggest sprinkler irrigation is a more promising climate adaptation in areas that are relatively cooler and …

Coastal Louisiana: Adaptive Capacity In The Face Of Climate Change, Tara Lambeth

LSU New Orleans Theses and Dissertations

Extreme weather events can result in natural disasters, and climate change can cause these weather events to occur more often and with more intensity. Because of social and physical vulnerabilities, climate change and extreme weather often affect coastal communities. As climate change continues to be a factor for many coastal communities, and environmental hazards and vulnerability continue to increase, the need for adaptation may become a reality for many communities. However, very few studies have been done on the effect climate change and mitigation measures implemented in response to climate change have on a community’s adaptive capacity.

This single instrumental …

Wildfire, Climate, And Perceptions In Northeast Oregon, Lawrence C. Hamilton, Joel N. Hartter, Barry D. Keim, Angela E. Boag, Michael W. Palace, Forrest R. Stevens, Mark J. Ducey

Sociology

Wildfire poses a rising threat in the western USA, fueled by synergies between historical fire suppression, changing land use, insects and disease, and shifts toward a drier, warmer climate. The rugged landscapes of northeast Oregon, with their historically forest- and resource-based economies, have been one of the areas affected. A 2011 survey found area residents highly concerned about fire and insect threats, but not about climate change. In 2014 we conducted a second survey that, to explore this apparent disconnect, included questions about past and future summertime (fire season) temperatures. Although regional temperatures have warmed in recent decades at twice …

Altitudinal Gradients Do Not Predict Plant-Symbiont Responses To Experimental Warming, Melanie R. Kazenel

Biology ETDs

Fungal symbionts, ubiquitous inhabitants of above- and belowground plant tissues, can play important roles in increasing plant tolerance to abiotic and biotic stress. Disruption of plant-fungal interactions may therefore have important consequences for plant responses to climate change. Both altitudinal gradients and warming experiments can be useful tools for understanding responses of symbioses to climate shifts, but the degree to which altitudinal patterns will predict species responses to warming has received little attention for plant-symbiont interactions. This study combined surveys along replicated altitudinal gradients with a long-term warming experiment at the Rocky Mountain Biological Laboratory (RMBL) in Colorado, USA to …

A Spatio-Temporal Comparison Of Avian Migration Phenology Using Citizen Science Data, Ali Arab, Jason R. Courter, Jessica Zelt

United States Geological Survey: Staff Publications

The effects of climate change have wide-ranging impacts on wildlife species and recent studies indicate that birds’ spring arrival dates are advancing in response to changes in global climates. In this paper, we propose a spatio-temporal approach for comparing avian first arrival data for multiple species. As an example, we analyze spring arrival data for two long-distance migrants (Rubythroated Hummingbird Archilochus colubris; and Purple Martin Progne subis) in eastern North America from 2001–2010 using Citizen Science data. The proposed approach provides researchers with a tool to compare mean arrival dates while accounting for spatial and temporal variability. Our results show …

Do Or Die: Environmental History, Environmental Politics And Environmental Economics And Their Implications For Mitigating The Effects Of Climate Change, Christopher Cannon

Student Theses 2015-Present

Beginning during the Industrial Revolution, global economic growth has been driven mainly by humanity’s ability to harness energy from the combustion of fossil fuels. Energy is a tremendously valuable resource; lands with few other resources yield wealthy nations, businesses, cartels, armies and kingdoms, grown primarily from deposits and reserves of coal, oil or natural gas below the land’s surface. Energy security is perhaps a prerequisite for a nation to achieve industrial and economic development, foreign investment and trade, and in most cases law and order. As energy markets stand today in our global economic system, the burning of oil and …

Agenda: Coping With Water Scarcity In River Basins Worldwide: Lessons Learned From Shared Experiences, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

Coping with Water Scarcity in River Basins Worldwide: Lessons Learned from Shared Experiences (Martz Summer Conference, June 9-10)

Water scarcity is increasingly dominating headlines throughout the world. In the southwestern USA, the looming water shortages on the Colorado River system and the unprecedented drought in California are garnering the greatest attention. Similar stories of scarcity and crisis can be found across the globe, suggesting an opportunity for sharing lessons and innovations. For example, the Colorado River and Australia's Murray-Darling Basin likely can share many lessons, as both systems were over-allocated, feature multiple jurisdictions, face similar climatic risks and drought stresses, and struggle to balance human demands with environmental needs. In this conference we cast our net broadly, exploring …

Reevaluating Wilderness Classification And Management In The Face Of Climate Change: A Reconsideration Of Values And Ecology, Katherine Fiedler

Pace Environmental Law Review

In recognizing that the very nature of wilderness is a human construct, the values sought to be preserved can and should be reevaluated, considering the importance of wilderness in light of climate change and global ecosystem resilience, as well as how wilderness is designated and managed. Furthermore, the values that wilderness provides us will dramatically increase as climate change proceeds. Section II of this article describes the basics of wilderness protection, including the evolution of our relationship with wilderness, the history of the Wilderness Act, and what, how, and why wilderness is protected under the Act. Section III explores how …

Climate Of Fear: How The Most Privileged Voices In America Have Made Climate Change Denial Mainstream, Duncan B. Magidson

Student Theses 2015-Present

Climate change is a serious threat to the continued existence of human civilization. Despite this, the United States has yet to pass meaningful legislation to cub greenhouse gas emissions. Although tackling environmental issues once had a broad bipartisan support, the issue of climate change has driven a wedge between Democratic and Republican voters and politicians. Consequently, the United States finds itself deadlocked in the political sphere, unable to come together on any real strategies to adapt to the realities of a changing world. The driving force behind the lack of American action on climate change is the persistence of denial. …

Estimated Effects Of Climate Change On The Reproductive Fitness Of The Northern Spotted Owl, Strix Occidentalis Caurina, Nadia Swit

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

In this paper, the trends for current and future climate change were utilized to evaluate the potential reproductive success of the Spotted Owl, particularly the Northern Spotted Owl (Strix occidentalis caurina) subspecies. As breeding season would exert additional stressors on the animal, a time period of five months, from January to June, was selected for the spring breeding season in which to evaluate temperature change. Previous research performed by Weathers and colleagues (2001) concerning the California Owl (Strix occidentalis occidentalis) formulated a thermodynamic equation that was utilized to compare the metabolic rate of the owl at …

Shareholder Advocacy In Corporate Elections: Case Studies In Proxy Voting Websites For Retail Investors, Robin Miller

Sustainability and Social Justice

One of the key rights shareholders retain is the right to vote on issues affecting the companies in which they invest. This voting right is seen as one of the primary means of exercising diligent corporate governance (Cole 2003, Fairfax 2009). Only 28 percent of individual investors vote in corporate elections compared with 91 percent of institutional investors. Informed voting decisions at corporate elections can be very information intensive, and theories of rational apathy and the free rider problem may explain a lack of participation from individual investors.

Many shareholders cannot attend annual corporate meetings, so they …

Long Live The King? A Gis Analysis Of Climate Change’S Impact On The Future Wintering Range And Economy Of The Monarch Butterfly (Danaus Plexippus) In Mexico, Megan E. Zagorski

Student Publications

The annual migration of the monarch butterfly (Danaus plexippus) is a natural phenomenon widely integrated into the popular and social imagination of North America. However, this migratory population has recently declined. I investigated the threat of climate change on the future distribution of suitable monarch habitat, using ArcGIS to create a model of current and future monarch habitat. I also analyzed municipal data for 5 communities in Mexico State in an examination of the social aspects of the Monarch Butterfly Biosphere Reserve [MBBR]. According to my model, an estimated 38.6% to 69.8% of current monarch habitat may be lost within …

Decadal Variability In The Oxygen Inventory Of North Atlantic Subtropical Underwater Captured By Sustained, Long-Term Oceanographic Time Series Observations, Enrique Montes, Frank E. Muller-Karger, Andrés Cianca, Michael W. Lomas, Laura Lorenzoni, Sennai Habtes

Marine Science Faculty Publications

Historical observations of potential temperature (θ), salinity (S), and dissolved oxygen concentrations (O₂) in the tropical and subtropical North Atlantic (0–500 m; 0–40°N, 10–90°W) were examined to understand decadal‐scale changes in O₂ in subtropical underwater (STUW). STUW is observed at four of the longest, sustained ocean biogeochemical and ecological time series stations, namely, the CArbon Retention In A Colored Ocean (CARIACO) Ocean Time Series Program (10.5°N, 64.7°W), the Bermuda Atlantic Time‐series Study (BATS; 31.7°N, 64.2°W), Hydrostation “S” (32.1°N, 64.4°W), and the European Station for Time‐series in the Ocean, Canary Islands (ESTOC; 29.2°N, 15.5°W). …

Waste Management Vs. Climate Mitigation: How Co2 Sparked A Clash Of Environmental Values, Wesley Dyer

Pace Environmental Law Review

The looming threats of climate change dominate global politics, national and economic security, science, and environmental policy. As such, global, national, regional, local, federal, and state strategies are being developed to slow and mitigate the devastating effects of a warming climate. One such strategy that is slowly being used on a global and national scale is geologic sequestration, where carbon dioxide (CO₂) is captured, compressed to a supercritical state, and injected underground for permanent removal from the atmosphere. At the same time, the Resource Conservation and Recovery Act (RCRA) regulates the transport, storage, and disposal of solid and …

In the spring of 2015, City & Regional Planning faculty conducted a campus-wide transportation survey as part of work on the campus Climate Action Plan. The survey represented spring 2014 commutes and was issued to a sample of full and part-time CalPoly faculty, staff, students and auxiliaries with assistance from Facilities Services and the Vice President for Administration and Finance.

The total number of responses was 3,961, roughly 17% of the entire campus population of roughly 23,000. Unsurprisingly, the majority of respondents were students, totaling 68.6%, while the rest were made up of faculty, staff, and visitors. Results are significant …

Riparian Trees And Aridland Streams Of The Southwestern United States: An Assessment Of The Past, Present, And Future, D. Max Smith, Deborah M. Finch

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Riparian ecosystems are vital components of aridlands within the southwestern United States. Historically, surface flows influenced population dynamics of native riparian trees. Many southwestern streams has been altered by regulation, however, and will be further affected by greenhouse warming. Our analysis of stream gage data revealed that decreases in volume of annual discharge and mean peak discharge and a shift to earlier peak discharge will occur in the Southern Rockies region of Colorado, New Mexico, and Utah. These changes will likely decrease rates of reproduction and survival of cottonwood (Populus fremontii and Populus deltoides ssp. wislizenii), Goodding's willow …

Using Cleaved Amplified Polymorphic Sequence (Caps) Genetic Markers To Determine The Extent Of Hybridization Between Castilleja Affinis And Castilleja Mollis As A Mechanism For Adapting To Climate Change On Santa Rosa Island, Elizabeth Medford

Scripps Senior Theses

Hybridization, the process of interbreeding between individuals of different species, is one method by which plants and animals adapt to a changing environment. One example of such adaptation through hybridization may be occurring on the California Channel Islands with two species of Castilleja. While United State Geological Survey (USGS) researchers have been studying the populations of Castilleja affinis and Castilleja mollis to determine if hybridization is occurring on Santa Rosa Island since the early 1990s, up until this point primarily overt phenotypic characteristics have been used to differentiate between the two species. Genetic methods of differentiation were adopted to …

Traditional Ecological Rulemaking, Anthony Moffa

Faculty Publications

This Article examines the implications of an increased role for Traditional Ecological Knowledge (TEK) in United States agency decisionmaking. Specifically, it contemplates where TEK might substantively and procedurally fit and, most importantly, whether a final agency action based on TEK would survive judicial scrutiny. In the midst of a growing body of scholarship questioning the wisdom of deference to agency expertise9 and the legitimacy of the administrative state writ large,10 this Article argues that there remains an important space in administrative rulemaking for the consideration of ways of understanding that differ from traditional Western norms. TEK can and should fill …

Faith In A Changing Planet: The Role Of Religious Leaders In The Fight For A Livable Climate, Morissa Zuckerman

Pitzer Senior Theses

Progressive religious leaders are playing an increasingly important role in the effort to combat climate change. Through a combination of unstructured in-depth interviews and primary source analysis, this thesis highlights nine U.S. religious leaders from various denominations of Christianity, Judaism and Islam who are actively involved in working on climate issues. Drawing on literature in social movement theory, I explore how clergy are uniquely influential in climate issues because of the organizational advantage and moral authority they hold through their positions as religious leaders, granting them the ability to highlight social justice implications of climate change with distinctive legitimacy. Clergy …

Identifying Plant Functional Traits To Assist Ecological Intervention In A Drying Landscape, Ana Luiza Muler

Theses: Doctorates and Masters

Mediterranean-type ecosystems (MTEs) are among the most vulnerable to land use and climate change and many attempts are in place to restore these ecosystems. Therefore, it is necessary to assess differences in plants’ ability to withstand water-stress, including biotic interactions. Such knowledge helps us understand community assembly, which is crucial for ecological intervention. This study involved: (1) reviewing the literature on traits that can differentiate functional types; (2) adapting the methodology to measure leaf water potential at turgor loss point (πtlp) for small-leaved species; (3) using these traits to quickly identify water-use strategies of adult …

Responses Of Marine Organisms To Climate Change Across Oceans, Elvira S. Poloczanska, Michael T. Burrows, Christipher J. Brown, Jorge G. Molinos, Benjamin S. Halpern, Ove Hoegh-Guldberg, Carrie V. Kappel, Philippa J. Moore, Anthony Richardson, David S. Schoeman, William J. Sydeman

Research outputs 2014 to 2021

Climate change is driving changes in the physical and chemical properties of the ocean that have consequences for marine ecosystems. Here, we review evidence for the responses of marine life to recent climate change across ocean regions, from tropical seas to polar oceans. We consider observed changes in calcification rates, demography, abundance, distribution, and phenology of marine species. We draw on a database of observed climate change impacts on marine species, supplemented with evidence in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. We discuss factors that limit or facilitate species' responses, such as fishing pressure, the …

Pre-Service Teachers And Climate Change: A Stalemate?, Helen J. Boon

Australian Journal of Teacher Education

Findings from the second phase of a study of pre-service teachers’ attitudes to environmental education and knowledge of climate change are reported in this paper. A sample of 87 pre-service teachers participated in a survey study in the last year of their Bachelor of Education degree to examine developments to their attitudes to environmental education and their knowledge of climate change as a result of training. Results showed their attitudes towards environmental education were consistently favourable, but their climate change science knowledge had not changed as a result of their participation in their degree. Data on preservice teachers’ sources of …

Trade-Offs Between Three Forest Ecosystem Services Across The State Of New Hampshire, Usa: Timber, Carbon, And Albedo, David A. Lutz, Elizabeth A. Burakowski, Mackenzie B. Murphy, Mark E. Borsuk

Dartmouth Scholarship

Forests are more frequently being managed to store and sequester carbon for the purposes of climate change mitigation. Generally, this practice involves long-term conservation of intact mature forests and/or reductions in the frequency and intensity of timber harvests. However, incorporating the influence of forest surface albedo often suggests that long rotation lengths may not always be optimal in mitigating climate change in forests characterized by frequent snowfall. To address this, we investigated trade-offs between three ecosystem services: carbon storage, albedo-related radiative forcing, and timber provisioning. We calculated optimal rotation length at 498 diverse Forest Inventory and Analysis forest sites in …

The Sea Is Rising… But Not Onto The Policy Agenda: A Multiple Streams Approach To Understanding Sea Level Rise Policies, Juita-Elena (Wie) Yusuf, Katharine Neill, Burton St. John Iii, Ivan K. Ash, Kaitrin Mahar

School of Public Service Faculty Publications

There has been little policy effort to address sea level rise in coastal states in the US. It is important to examine, at the state level, how the multitude of different (and changing) actors with different preferences and perspectives contribute to such inertia. This study examines state-level legislative inaction with regards to sea level rise. Using Kingdon's multiple streams framework, we draw a picture of the policy landscape in Virginia as one where the problem of sea level rise is perceived as a low priority, with little consensus on achievable policy solutions, and is politically controversial. We find that policy …
