The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …

Ecosystem Response To Recent Climate Change In Alpine Environments, Patrick Shawn Sawyer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent variations in meteorological conditions indicate the earth’s climate is changing in ways that can impact delicate ecological balances in sensitive regions. These impacts threaten the essential services provided by such ecosystems. Determining how climate changes are affecting the biosphere is essential to adapt and mitigate harmful consequences. In order to mitigate the negative effects of climate change and adapt to shifting ecological resource constraints, it is imperative to locate such changes and determine vulnerability of ecological resources to changing environmental conditions.

Identifying climate driven ecological changes faces numerous challenges given the reliance on vegetation indices as the primary measure …

Climate Change And Interpersonal Violence: A "Global" Estimate And Regional Inequities, Dennis Mares, Kenneth W. Moffett

SIUE Faculty Research, Scholarship, and Creative Activity

This study estimates the predicted impact of climate change on levels of violence in a sample of 57 countries. We sample western and non-western countries and perform a multilevel ARFIMA regression to examine if warmer temperatures are associated with higher levels of homicide. Our results indicate that each degree Celsius increase in annual temperatures is associated with a nearly 6% average increase in homicides. Regional variation in this predicted effect is detected, for example, with no apparent effects in former Soviet countries and far stronger effects found in Africa. This variation indicates that climate change may acutely increase violence in …

Analysis Of The Impact Of Technological Change On The Cost Of Achieving Climate Change Mitigation Targets, Robert W. Barron

Doctoral Dissertations

There is widespread consensus that low carbon energy technologies will play a key role in the future global energy system. Many of the low-carbon technologies under consideration are not yet commercially available, and their ultimate value depends on a host of deeply uncertain socioeconomic, environmental, and technological considerations. While it is clear that significant investment in the energy system is needed, the optimal allocation of these investments is unclear. This dissertation develops a methodology for (1) analyzing the impact of low carbon energy technologies on the cost of meeting emission reduction targets (policy cost) and (2) using this information to …

The 2011 Great Flood In Thailand: Climate Diagnostics And Implications From Climate Change, Parichart Promchote, S. -Y. Simon Wang, Paul G. Johnson

Plants, Soils, and Climate Faculty Publications

Severe flooding occurred in Thailand during the 2011 summer season, which resulted in more than 800 deaths and affected 13.6 million people. The unprecedented nature of this flood in the Chao Phraya River basin (CPRB) was examined and compared with historical flood years. Climate diagnostics were conducted to understand the meteorological conditions and climate forcing that led to the magnitude and duration of this flood. Neither the monsoon rainfall nor the tropical cyclone frequency anomalies alone was sufficient to cause the 2011 flooding event. Instead, a series of abnormal conditions collectively contributed to the intensity of the 2011 flood: anomalously …

Climate Impact On Groundwater Flow Processes In The Cedar Creek Watershed And Cedarburg Bog, Jackson Graham

Theses and Dissertations

A local-scale groundwater-flow model of the Cedar Creek Watershed and Cedarburg Bog area was constructed to determine the effects of future changes in temperature and precipitation on water resources. The Cedar Creek Watershed is a 330 km2 sub-basin of the Milwaukee River Watershed located about 30 km north of Milwaukee. The importance of this watershed lies in its location at the sub-continental divide separating the Mississippi River Basin from the Great Lakes Basin. The coupled steady-state and transient flow models incorporate interaction between surface water features and groundwater-surface water interactions. The 4 layer model simulates the influence of recharge on …

Springtime Melt Onset On Arctic Sea Ice From Satellite Observations And Related Atmospheric Conditions, Angela C. Bliss

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

The timing of snowmelt onset (MO) on Arctic sea ice derived from passive microwave satellite data is examined by determining the melting area (in km²) on a daily basis for the spring and summer melt season months over the 1979 – 2012 data record. The date of MO on Arctic sea ice has important implications for the amount of total solar energy absorbed by the ice-ocean system in a given year. Increasingly early mean MO dates have been recorded over the 34-year data record as evidenced by statistically significant trends of 6.6 days decade^-1 over the extent …

Valuing “Green” How “Going Green” Affects A Company’S Stock Price, Alexia Bayer

Honors Projects in Finance

Environmentally conscious decision making has become a prominent topic in business that has the potential to affect the public opinion and performance of companies. This project seeks to identify whether or not positive changes in excess return might offer an incentive for companies to adopt green initiatives. It examines the ways in which companies’ green initiatives, as measured by their annual Carbon Disclosure Project S&P 500 Climate Change Report score, impact their stock price. In other words, is there value in “going green”? It is hypothesized that companies exhibiting greater variance in their environmental initiatives from one year to the …

Impact Of A Changing Climate On Fine Particulate Concentrations In Butte, Mt, Christopher Atherly

Graduate Theses & Non-Theses

A model was developed to assess the potential change in PM_2.5 concentrations in Butte, Montana over the course of the 21^st century as the result of climate change and changes in emissions. The EPA AERMOD regulatory model was run using NARCCAP climate data for the years of 2040, 2050, 2060 and 2070, and the results were compared to the NAAQS to determine if there is the potential for future impacts to human health. This model predicted an average annual concentration of 15.84 µg/m³ in the year 2050, which would exceed the primary NAAQS of 12 µg/m^{3 …}

Let’S Act Now, While Things Are Good! Social Change And The Need For Policy Action In Maine’S Lobster Industry, Samuel Belknap

The Cohen Journal

The motivation behind this letter was a remark by Maine Department of Marine Resources Lobster Biologist, Carl Wilson. While attending the Rockland Maine based Island Institute’s annual Climate Round Table event, where fishermen, scientists, and others gather to talk about the past year in the Gulf of Maine, Wilson said, in reference to the lobster industry, “When the resource changes, everything changes.” This comment, poetic in its simplicity, got me to start thinking. I began retracing the history of Maine’s lobster industry to find examples of Wilson’s statement, and I was surprised by how many instances supported this comment. What …

Land Use And Climate Change Bubbles: Resilience, Retreat, And Due Diligence, John R. Nolon

William & Mary Environmental Law and Policy Review

This Article examines events on the ground in several localities where climate change is lowering property values and analyzes how those changes in value can be reckoned with by regulators. It merges practices and principles of real estate transactions and finance with those of land use and environmental regulation.

Climate change is a planetary phenomenon whose environmental implications are far-reaching. Reports on climate change consequences increasingly focus on what is happening locally and presently, while speculation continues about long-term global consequences. In numerous communities, property values are declining because of repeated flooding, continued threats of storm surges, sustained high temperatures, …

Collaborative Research: Byrd Glacier Flow Dynamics, Gordon S. Hamilton

University of Maine Office of Research Administration: Grant Reports

This award supports a project to understand the flow dynamics of large, fast-moving outlet glaciers that drain the East Antarctic Ice Sheet. The project includes an integrated field, remote sensing and modeling study of Byrd Glacier which is a major pathway for the discharge of mass from the East Antarctic Ice Sheet (EAIS) to the ocean. Recent work has shown that the glacier can undergo short-lived but significant changes in flow speed in response to perturbations in its boundary conditions. Because outlet glacier speeds exert a major control on ice sheet mass balance and modulate the ice sheet contribution to …

Cumulative pressures from global climate and ocean change combined with multiple regional and local-scale stressors pose fundamental challenges to coral reef managers worldwide. Understanding how cumulative stressors affect coral reef vulnerability is critical for successful reef conservation now and in the future. In this review, we present the case that strategically managing for increased ecological resilience (capacity for stress resistance and recovery) can reduce coral reef vulnerability (risk of net decline) up to a point. Specifically, we propose an operational framework for identifying effective management levers to enhance resilience and support management decisions that reduce reef vulnerability. Building on a …

HPRCC Personnel Publications

This study investigates the geological background of the August 7-8, 2010 Zhouqu debris flows in the northwestern Chinese province of Gansu, and possible future occurrence of such hazards in the peri-Tibetan Plateau (TP) regions. Debris flows are a more predictable type of landslide because of its strong correlation with extreme precipitation. However, two factors affecting the frequency and magnitude of debris flows: very fine scale precipitation and degree of fracture of bedrock, both defy direct observations. Annual mean Net Primary production (NPP) is used as a surrogate for regional precipitation with patchiness filtered out, and gravity satellite measured regional mass …

IGC Proceedings (1997-2023)

Grasses are unique group of flowering plants that form the foundation for the trophic structure in terrestrial communities. The grasses are found in every conceivable habitat where plants can thrive – from sea to deserts and from wetlands to peaks of highest mountains. The grasses form a distinct biome – a major ecological formation in the global classification of vegetation.

Using Empirical Mode Decomposition To Study Periodicity And Trends In Extreme Precipitation, Noah Pfister

Graduate College Dissertations and Theses

Classically, we look at annual maximum precipitation series from the perspective of extreme value statistics, which provides a useful statistical distribution, but does not allow much flexibility in the context of climate change. Such distributions are usually assumed to be static, or else require some assumed information about possible trends within the data. For this study, we treat the maximum rainfall series as sums of underlying signals, upon which we perform a decomposition technique, Empirical Mode Decomposition. This not only allows the study of non-linear trends in the data, but could give us some idea of the periodic forces that …

Sustainable Agriculture In Vermont: Economics Of Climate Change Best Management Practices And The Complexity Of Consumer Perceptions Of Raw Milk, Alexander Paul Helling

Changing weather patterns, the declining social fabric of rural communities, and economic uncertainty increasingly pose challenges to Vermont communities. The socially and environmentally embedded production practices within sustainable agriculture present a potential solution to these problems. In order to make the most of the potential benefits of these practices society must maximize their adoption. This requires an understanding of both farmer adoption of these practices and consumer perceptions of the resulting food products. This thesis contributes two original articles on sustainable agriculture through the analysis of factors driving both farmer adoption and consumer perceptions of products and practices often thought …

Ridazz, Wrenches, And Wonks: A Revolution On Two Wheels Rolls Into Los Angeles, Donald Parker Strauss

Antioch University Full-Text Dissertations & Theses

How can we make cities more livable? Los Angeles, in particular, is a notably challenging place to live. For many, it is hard to see Los Angeles—city or county—as anything other than a huge, sprawling, and some would say placeless place. Los Angeles is known by many as the place that tore up more than 1,000 miles of streetcar lines to make way for millions of cars and hundreds of miles of freeways. Because of this, Los Angeles is also known for its poor air quality and jammed freeways. Those who live in Los Angeles know that it can be …

Rural Year-Round Growing To Ameliorate A Possible Negative Effect From Climate Change, Kimberlie A. Brussa

Walden Dissertations and Doctoral Studies

The Intergovernmental Panel on Climate Change (IPCC) suggested that, as the world population grows, food and water shortages will become even more serious issues (IPPC's 2014 predictions about the future effects of climate change (CC), Year-round growing (YRG) may provide a way for communities to extend growing seasons, expand local farm systems, and provide food year round. This case study included a detailed analysis of responses from representatives of all sectors of rural Mesa County, Colorado, regarding YRG and a local food and farm plan due to CC. The case was bounded by time (6 months of data collection) which …
