Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman May 2020

Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman

Electronic Theses and Dissertations

Soil erosion is of escalating importance as increasing population and climate change have put increasing pressures on agricultural food production. Vegetation and precipitation are two factors that control the amount of soil erosion extant within a region. Sediment delivery ratios (SDRs) assess the ratio of soil eroded from a watershed system that is permanently removed from the system through stream sediment discharge. Using 1) river discharge and sediment concentration data and 2) the Revised Universal Soil Loss Equation (RUSLE), this thesis analyzes fluctuations in monthly SDRs for an average hydroclimatological crop-harvest season for the Senachwine Creek watershed, IL. Through calculating …

Climate Change And Liberation In Latin America, Ernesto O. Hernández Apr 2020

Climate Change And Liberation In Latin America, Ernesto O. Hernández

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to propose the liberation movements in Latin America as alternative philosophical frameworks to the crisis of climate change. These movements have provided the grounds to identify inequities and injustices and have practiced ethical methodologies to overcome them. Additionally, the movements seek to represent and reflect the value of non-traditional philosophical agents in Latin America. The work focuses on four major Latin American ecological liberation movements; theology, philosophy, pedagogy, and feminism. Eco-Theology advances the role of Religion as the practice of Religação, reexamination, and resetting our relationship with nature by reconnecting with it. Eco-Philosophy of …

Gen Z Perspectives On Climate Change And The Future: Having The Courage To Imagine And Fight For A Better World, Isabelle Graj Apr 2020

Gen Z Perspectives On Climate Change And The Future: Having The Courage To Imagine And Fight For A Better World, Isabelle Graj

Independent Study Project (ISP) Collection

I conducted 6 interviews with Gen Z students to investigate how they think climate change will impact their future and how they frame the issue in general. I communicate my findings and analysis with visual context through a zine, which is a form of alternative media created in the 1930s. Today, zines provide a creative approach to exchange ideas and explain contemporary culture (Gisonny and Freedman, 2006, 26). My zine is not meant to be utterly educational but rather it is meant to convey the emotion, confusion, and chaos associated with my findings. The interviews collectively created an image of …

La relación entre el cambio climático y la salud pública es un tema emergente y crítico para estudiar en la escala local, concretamente en lo que refiere a analizar los efectos producidos por las olas de calor y las inundaciones. Si bien existe un campo de investigación creciente sobre el tema, son pocos los trabajos que ahondan en la conexión con la salud pública, un elemento central para pensar en la gestión del cambio climático en las ciudades. Esto es precisamente lo que se propone hacer la presente investigación, tomando como caso de estudio la cuenca más urbanizada e industrializada …


Surviving Under The Reign Of El Niño Southern Oscillation: An Analysis Of The Effects Of Extreme El Niño Events On The Oceanographic And Biological Environment Of The Galápagos Islands, Ava Mcilvaine Apr 2020

Surviving Under The Reign Of El Niño Southern Oscillation: An Analysis Of The Effects Of Extreme El Niño Events On The Oceanographic And Biological Environment Of The Galápagos Islands, Ava Mcilvaine

Independent Study Project (ISP) Collection

El Niño Southern Oscillation (ENSO) is commonly known as the atmospheric and oceanographic powerhouse of the Southern Pacific Ocean. From phytoplankton to apex predators, ENSO controls the stability of species’ populations within this biodiverse ocean environment. El Niño’s 9-15 month alteration of the heat storage in the tropical Pacific drastically shifts the temperature, nutrient, and circulation gradient its marine life is accustomed to. A single degree change in the ocean’s surface layer temperature can have large consequences for marine species, and El Niño is commonly associated with Sea Surface Temperature Anomalies (SSTAs) between 2°- 6° Celsius. The potential danger El …

Climate Change Effects On Volcanoes In The Tropics: A Review Of The Deglaciation Of Antisana And Its Effects On Subsequent Water Streams And Rivers Over 20 Years, Callie C. Rominger

Independent Study Project (ISP) Collection

Located in the Northern end of Ecuador lies the stunning glacier of Antisana which attracts many tourists and whose runoff provides a significant amount of water supply for Quito. Climate change is posing threats to many ecosystems world wide but will have a more substantial impact on the volcanoes in the tropics because they do not have a seasonally altered climate. Small changes in the air temperature can have larger impacts on these areas that are adapted to constant temperatures with seasonal precipitation changes. Climate change, in recent years, had caused an increase in the glacial retreat of the Antisana …

Macroinvertebrate Community And Temperature Changes In A Michigan Stream, Nyika Campbell Apr 2020

Macroinvertebrate Community And Temperature Changes In A Michigan Stream, Nyika Campbell

Independent Study Project (ISP) Collection

As the climate warms, global biodiversity is plummeting and extinction rates are rising (Jenkins, 2003). Freshwater ecosystems specifically are experiencing huge losses in diversity (Jenkins, 2003; Ormerod et al., 2010; Collier et al., 2016). Conservation of invertebrates is particularly urgent because they are foundational to the trophic systems in streams and lakes, comprising 95% of all species on earth (Titley et al., 2017), and over 60% of biodiversity in freshwater ecosystems (Collier et al., 2016). Through analysis of both my own field measurements and historical data I seek to gain a preliminary understanding of temperature and macroinvertebrate community changes that …


Conservation Efforts Concerning Native Bee Species Of Michigan, Thomas Hellman Apr 2020

Conservation Efforts Concerning Native Bee Species Of Michigan, Thomas Hellman

Independent Study Project (ISP) Collection

Bee species all over the world are declining at concerning rates. However, it is good to see the public rallying behind the “save the bees!” movement even though most efforts from this movement have been on the conservation of the European honeybees. This is because most people often associate the honeybee, which is only one of 20,000 known bee species in the world, to all other bees. Therefore, conservation efforts should be broadened and aimed towards the many native bee species that can be found locally in North America. In the state of Michigan, there are over 450 species, and …


Crude Intentions: Evaluating The Growing Risks Of Arctic Alaskan Oil Production, Eliot Stein Apr 2020

Crude Intentions: Evaluating The Growing Risks Of Arctic Alaskan Oil Production, Eliot Stein

Independent Study Project (ISP) Collection

The discovery of oil on Alaska’s North Slope in the 1920s began a century of fossil fuel exploration, development, and production in the Arctic region. Alaska became integral to the nation’s growing energy dominance. However, since 1988, oil production on the North Slope has been in steady decline. In 2015, Shell, followed by several other oil majors, terminated their Arctic Alaska operations. This past year, BP made waves by ending six decades of operations in Alaska. Most recently, five of the six major U.S. banks announced they would no longer finance Arctic oil and gas projects. This paper analyzes these …

What Is The Most Threatening Disaster To The Continental United States?, Aaron Spomer, Elijah Kaufman, Julisa Prieto-Garcia, Brooke Aschwanden

UNO Student Research and Creative Activity Fair

Our goal for our project is to fully understand which natural disaster is the most destructive to the United States. We have chosen to compare hurricanes, floods, tornadoes, wildfires, earthquakes, and nor’easters. We have researched the cost of the total damage and repair, how the warning systems have improved over time, the death tolls from each, and also the frequency at which each one occurs. Each group member will research a different disaster impact, and the data will create a comprehensive view of the level of devastation each disaster has. We collected data all the way from the early 1900s …

Utilizing Objective Drought Severity Thresholds To Improve Drought Monitoring, Zachary T. Leasor, Steven M. Quiring, Mark D. Svoboda Mar 2020

Utilizing Objective Drought Severity Thresholds To Improve Drought Monitoring, Zachary T. Leasor, Steven M. Quiring, Mark D. Svoboda

National Drought Mitigation Center: Faculty Publications

Drought is a prominent climatic hazard in the south-central United States. Drought severity is frequently classified using the categories established by the U.S. Drought Monitor (USDM). This study evaluates whether the thresholds for the standardized precipitation index (SPI) used by the USDM accurately classify drought severity. This study uses the SPI based on PRISM precipitation data from 1900 to 2015 to evaluate drought severity in Texas, Oklahoma, and Kansas. The results show that the fixed SPI thresholds for the USDM drought categories may lead to a systematic underestimation of drought severity in arid regions. To address this issue, objective drought …

Rockhounding, Seafaring, And Other Material Tales For The End Of The World, Noemie Fortin

The Goose

In the face of accelerated environmental degradation and climate instability, the future of the Earth and of all life on earth is difficult to visualize. Therefore, the different mediums through which we consider environmental issues are just as important as the actions we take to address them. Focusing on three projects combining art, science, and activism, this article suggests a compilation of material tales. They tell stories of plastic rocks and aluminum nuggets where the protagonists are partly finely crafted objects, partly waste materials, and sometimes both at once. Artists Kelly Jazvac, Yesenia Thibeault-Picazo, and the collective Studio Swine collaborate …

Assessing Boreal Peat Fire Severity And Vulnerability Of Peatlands To Early Season Wildland Fire, Laura Bourgeau-Chavez, Sarah L. Grelik, Michael Billmire, Liza K. Jenkins, Eric S. Kasischke, Merritt R. Turetsky

Michigan Tech Publications, Part 1

Globally peatlands store large amounts of carbon belowground with 80% distributed in boreal regions of the northern hemisphere. Climate warming and drying of the boreal region has been documented as affecting fire regimes, with increased fire frequency, severity and extent. While much research is dedicated to assessing changes in boreal uplands, few research efforts are focused on the vulnerability of boreal peatlands to wildfire. In this case study, an integration of field data collection, land cover mapping of peatland types and Landsat-based fire severity mapping was conducted for four early season (May to mid-June) wildfires where peatlands are abundant in …

All Faculty Scholarship for the College of the Sciences

Light absorbing particles (LAPs) include black carbon (BC) and mineral dust and are of interest due to their positive radiative forcing and contribution to albedo reductions and snow and glacier melt. This study documents historic BC and dust deposition as well as their effect on albedo on South Cascade Glacier (SCG) in Washington State (USA) through the analysis of a 158‐m (139.5‐m water equivalent [w.e.]) ice core extracted in 1994 and spanning the period 1840–1991. Peak BC deposition occurred between 1940 and 1960, when median BC concentrations were 16 times higher than background, likely dominated by domestic coal and forest …

A Design For A Sustained Assessment Of Climate Forcing And Feedbacks Related To Land Use And Land Cover Change, Thomas Loveland, Rezaul Mahmood

High Plains Regional Climate Center: Staff Publications

L and use and land cover change (LULCC) plays an important role in the climate system. Many studies have documented the impacts of LULCC on local, regional, and global climate. The National Climate Assessment Report (Melillo et al. 2014) identifies LULCC as a “cross cutting” issue of future climate change studies. This report, and the previous U.S. Climate Change Science Program strategic plan (2003), noted that land use and land cover (LULC) and its feedback is an important source of uncertainty within the climate system (Melillo et al. 2014). As a result, the report calls for a better understanding of …

Tasci, and Dr. Jill Fjelstul, along with Dr. Roberta Atzori from California State University, Monterey Bay, examines how social representations of climate change may affect a choice of holiday destination. In particular, they examine how they might …


Are New Hampshire’S Winters Warming? Yes, But Fewer Than Half Of State Residents Recognize The Trend, Lawrence C. Hamilton, Elizabeth Burakowski Feb 2020

Are New Hampshire’S Winters Warming? Yes, But Fewer Than Half Of State Residents Recognize The Trend, Lawrence C. Hamilton, Elizabeth Burakowski

Carsey Publications

In this brief, authors Elizabeth Burakowski and Lawrence Hamilton review some basic evidence about winter warming in New Hampshire, explore to what extent state residents are aware of this trend, and ask who is aware, in terms of characteristics such as age, education, or participation in winter sports. Results from two statewide surveys find limited awareness of the trend overall, and no significant differences by age, education, or winter sports participation. Instead, perceptions of this winter trend depend on political identity: conservatives are much less likely than other groups to recognize that warming has occurred.
