The Green New Deal is the best way for our country to become more sustainable, modernize our energy infrastructure, and do it without costing americans jobs. First off the Green New Deal will create 20 million new job openings according to Bernie Sanders campaign …


Adaptation To Climate Change, Pascal Ntaganda Dec 2019

Adaptation To Climate Change, Pascal Ntaganda

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Climate is changing rapidly. Some scientists say that the effects are now irreversible. The foundation on which government organizations, some of them being the congress in the United States, is not strong enough to stop climate change. The fact that the approaches being taken target market-based situations, makes it inefficient. Governments create solutions to reduce the impacts, as they make sure that these activities do not affect their economies. The level at which effects of climate change threaten life and resources of a country, is what stimulates the economy to adapt to the strategies set to mitigate climate change. In …

Facts, Not Feelings, Gannon Rush

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

“The world is gonna end in 12 years if we don't address climate change and your biggest issue is how are we gonna pay for it? ” This is a direct quote from Alexandria Ocasio-Cortez, a sitting U.S. congresswoman. In the next few sentences, she also proceeds to say that climate change is “our generations World War II”. 70 million people died in World War II, not only is it doing disrespect to those who gave the ultimate sacrifice, but it is physically impossible to compare war to climate change. What she and others, such as Greta Thunberg and Al …


Wind Is The First Step To Winning, Martin Brannaman Dec 2019

Wind Is The First Step To Winning, Martin Brannaman

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Wind energy is the way of the future, and those who don’t have it will get left behind. Wind has already proven to be useful to countries in Europe, such as Denmark, Germany, and Spain. These countries are benefited from EU policy, to help alleviate some economic stress that might come from having diversified energy sources. This diversification of energy is good for countries economically and energy wise, allows them to not be too heavily reliant upon one source. This issue is clearly on display in America who is heavily reliant on oil and coal for example, the 1973 oil …


California Stream Condition Index (Csci) Score Analysis Of Streams Sampled From 1998 To 2017 In The San Francisco Bay Region, Jenna Rais Dec 2019

California Stream Condition Index (Csci) Score Analysis Of Streams Sampled From 1998 To 2017 In The San Francisco Bay Region, Jenna Rais

Master's Projects and Capstones

Human impacts to California’s streams have altered the state’s riparian and hydrological landscape. This is a critical issue with regard to natural resources, including ecosystem services such as water availability and water quality. Regulations have a limited amount of impact on the improvement of this landscape and can also become complicated by politics. Scientific advances have developed ways to quantify and describe the quality of streams, this includes the development of the California Stream Condition Index (CSCI) which is based on benthic macroinvertebrate (BMI) population numbers and functions. This index allows scientists to not only score the quality of a …


The Dirty Clean Fuel, Sawyer Krivanek Dec 2019

The Dirty Clean Fuel, Sawyer Krivanek

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Hydraulic fracking began nearly 80 years ago and was initially headlined as a brand new, fuel efficient alternative to coal and oil. Natural gas has been disguised as a clean fuel, when in reality it is just another dirty, polluting, environmentally harmful fossil fuel. The detriments of fracking heavily outweigh the benefits, and it needs to be banned on public and private lands. Natural gas has been viewed as a cleaner alternative to coal and oil, so immediately fossil fuel industries took advantage of that narrative. Consumers, eager for cleaner alternatives, have been tricked into buying into the fracking fad. …


Don’T Give Up On Nuclear Energy, Daniel Gertner Dec 2019

Don’T Give Up On Nuclear Energy, Daniel Gertner

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The nuclear power plant failures at Three Mile Island and Chernobyl in the late 1970s and 1980s split Americans into two passionate camps. For some, nuclear plants posed serious threats to both environmental and national security, and, for others, nuclear energy remained the most viable path to clean, reliable power in the United States. But following the fervent debates of the late 20th century, the national conversation around nuclear power stagnated. A few ardent advocates and opponents notwithstanding, nuclear power left the public eye. Popular energy debates—especially among young people—now center around flashier topics like the Green New Deal, electric …


Air Quality And Environmental Justice: An Analysis Of County-Level Data In The United States, Alyssa Tittle Dec 2019

Air Quality And Environmental Justice: An Analysis Of County-Level Data In The United States, Alyssa Tittle

Honors Theses

This paper analyzes the relationship between air pollution and poverty and race/ethnicity at the county level in the United States. Using air pollution data from the Environmental Protection Agency and population characteristics data from the Census Bureau to model relationships in RStudio, results show that race/ethnicity, population, and median value of owner-occupied housing units are the most statistically significant variables associated with air quality.


Rain Gardens: The Return Of Ecosystem Services, Katie Dehaan Dec 2019

Rain Gardens: The Return Of Ecosystem Services, Katie Dehaan

Honors Theses

In the modern world impervious surfaces, especially in urban areas, abound. These include roads, highways, sidewalks, parking lots, and roofs that have replaced permeable surfaces, mainly open land, forests, and wetlands. Rainwater runs off of these surfaces collecting pollutants on its way to permeable areas. Rain gardens collect and process rainwater. Native plants with deep root systems process large volumes of rainwater and the microorganisms living in the soils and roots can process pollutants. The purpose of my research was to find out what variables affect species presence or absence in rain gardens. Species presence or absence at the time …

Hunters And Their Perceptions Of Public Access: A View From Afield, Joseph J. Fontaine, Alexis D. Fedele, Lyndsie S. Wszola, Lindsey N. Messinger, Christopher J. Chizinski, Jeffery J. Lusk, Karie L. Decker, J. Scott Taylor, Erica F. Stuber

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Declining hunter participation threatens cultural traditions and public support for conservation, warranting examination of the forces behind the downward trajectory. Access to lands for hunting, an often-cited reason for non participation, may play a critical role in the retention and recruitment of hunters. Meeting the access needs of a diverse hunting constituency requires understanding how hunters use and perceive access opportunities, particularly public-access sites. Given that perceptions of access are entirely place based and degrade with time, traditional postseason survey methods may fail to adequately quantify the value of public access to the hunting constituency. To overcome the potential limitations …


Effects Of Environmentally Relevant Concentrations Of Microplastic Fibers On Pacific Mole Crab (Emerita Analoga) Mortality And Reproduction, Dorothy Horn, Elise F. Granek, Clare Steele Dec 2019

Effects Of Environmentally Relevant Concentrations Of Microplastic Fibers On Pacific Mole Crab (Emerita Analoga) Mortality And Reproduction, Dorothy Horn, Elise F. Granek, Clare Steele

Environmental Science and Management Faculty Publications and Presentations

Microplastics are ubiquitous in marine systems; however, knowledge of the effects of these particles on marine fauna is limited. Ocean-borne plastic debris accumulates in littoral ecosystems worldwide, and invertebrate infauna inhabiting these systems can ingest small plastic particles and fibers, mistaking them for food. We examined the effect of microplastic fibers on physiological and reproductive outcomes in a nearshore organism by exposing Pacific mole crabs (Emerita analoga) to environmentally relevant concentrations of microsized polypropylene rope fibers. We compared adult gravid female crab mortality, reproductive success, and embryonic developmental rates between microfiber-exposed and control crabs. Pacific mole crabs exposed to polypropylene …


Modeling Lake Temperature Response To Climate Change In The Alaskan Arctic, Thomas Balkcom Dec 2019

Modeling Lake Temperature Response To Climate Change In The Alaskan Arctic, Thomas Balkcom

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This thesis study focuses on simulating lake temperature and ice duration for four lakes at the Arctic Long-Term Ecological Research site, near the Toolik Field Station in Alaska. Model projections were driven by the representative global climate model outputs under different carbon emission scenarios. Results show that my simple lake model can reproduce historical lake temperature and ice duration observations, indicating the reliability of the model for future projections. Model projections show that JuneSeptember lake temperatures would increase by 4.3-5.8 °C from the historical period with most progressive carbon emission scenarios, but by 0.7-2.2 °C in the conservative scenarios. Results …

As the demand for freshwater resources increases due to increasing human populations, degradation of available resources, and climatic changes it will become increasingly important to understand the factors that impact the physicochemical characteristics of surface water resources over space and time. This study assessed a headwater stream over the course of a year in the San Bernardino National Forest that serves as both surface and groundwater resources for the Santa Ana River Watershed region, the largest and most populated watershed in Southern California. Streams were monitored bi-weekly during dry periods and weekly during wet periods from April 2018 through April …


Interpreting Potential Groundwater Policies Through Modeling Of Market And Non-Market Benefits And Costs, Grant H. West Dec 2019

Interpreting Potential Groundwater Policies Through Modeling Of Market And Non-Market Benefits And Costs, Grant H. West

Graduate Theses and Dissertations

Current policies leveraging financial incentives and improved irrigation efficiency to mitigate groundwater scarcity have not proven to curtail trends of resource depletion. Groundwater benefits cannot be appropriately valued solely on market forces, and so deeper policy consideration is warranted under a framework that considers the importance of groundwater across all its values to society. Understanding time preferences for groundwater management and preferences for alternative policies is vital to inform efficient policies. Furthermore, climate change remains politically controversial yet has important consequences for critical groundwater resources and their sustainable long-term management. Proliferating policy narratives concerning climate change could influence the way …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Natural and anthropogenic aerosols over the Kingdom of Saudi Arabia (KSA) play a major role in affecting the regional radiation budget. The long-term variability of these aerosols’ physical and optical parameters, including aerosol optical depth (AOD) and Ångström exponent (α), were measured at a location near central KSA using the Solar Village (SV) AERONET (Aerosol Robotic Network) station during the period December 1999–January 2013. The AERONET measurements show an overall increase in AOD on an annual basis. This upward trend is mainly attributed to a prolonged increase in the monthly/seasonal mean AOD during March–June and during August– September. In contrast, …


Using Paleosols To Reconstruct Past Environments Before, During And After Periods Of Anatomically Human Migration At Gona, Ethiopia, Kevin Takashita-Bynum Nov 2019

Using Paleosols To Reconstruct Past Environments Before, During And After Periods Of Anatomically Human Migration At Gona, Ethiopia, Kevin Takashita-Bynum

Steeplechase: An ORCA Student Journal

Environmental change is thought to have driven dispersals of Anatomically Modern Humans (AMH) out of Africa, yet the precise landscape context of these migrations remains unclear. Furthermore, river-based archives of paleoenvironment during periods of dispersal are scarce. Gona, an area in northeastern Ethiopia with one of the most continuous records of East African Paleolithic and Neolithic archaeology, contains abundant Middle to Late Pleistocene river deposits interbedded with volcanic ash. This study examines the physical and chemical changes of 11 fossilized soils (paleosols) extracted from Gona’s paleoanthropological sites that range in age from the Middle to the Late Pleistocene (~380-11 ka). …

Microplastics are an ecological stressor with implications for ecosystem and human health when present in seafood. We quantified microplastic types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 Oregon coast, U.S.A. sites. Microplastics were present in organisms from all sites. On average, whole oysters and razor clams contained 10.95 ± 0.77 and 8.84 ± 0.45 microplastic pieces per individual, or 0.35 ± 0.04 pieces g−1 tissue and 0.16 ± 0.02 pieces g−1 tissue, respectively. Contamination was quantified but not subtracted. Over …

It has been shown that the foliar application of inorganic nano-materials on cereal plants during their growth cycle enhances the rate of plant productivity by providing a micro-nutrient source. We therefore studied the effects of foliarly applied ZnO nanoparticles (ZnO NPs) on Setaria italica L. foxtail millet’s quantitative, nutritional, and physiological parameters. Scanning electron microscopy showed that the ZnO NPs have an average particle size under 20 nm and dominant spherically shaped morphology. Energy dispersive X-ray spectrometry then confirmed ZnO NP homogeneity, and X-ray diffraction verified their high crystalline and wurtzite-structure symmetry. Although plant height, thousand grain weight, and grain …

Widespread Severe Wildfires Under Climate Change Lead To Increased Forest Homogeneity In Dry Mixed-Conifer Forests, Brooke Alyce Cassell, Robert M. Scheller, Melissa S. Lucash, Matthew Hurteau, E. Louise Loudermilk

Environmental Science and Management Faculty Publications and Presentations

Climate warming in the western United States is causing changes to the wildfire regime in mixed-conifer forests. Rising temperatures, longer fire seasons, increased drought, as well as fire suppression and changes in land use, have led to greater and more severe wildfire activity, all contributing to altered forest composition over the past century. To understand future interactions among climate, wildfire, and vegetation in a fire-prone landscape in the southern Blue Mountains of central Oregon, we used a spatially explicit forest landscape model, LANDIS-II, to simulate forest and fire dynamics under current management practices and two projected climate scenarios. The results …

Environmental Science and Management Faculty Publications and Presentations

Commercial fisheries yield essential foods, sustain cultural practices, and provide widespread employment around the globe. Commercially harvested species face a myriad of anthropogenic threats including degraded habitats, changing climate, overharvest, and pollution. Microplastics are pollutants of increasing concern, which are pervasive in the environment and can harbor or adsorb pollutants from surrounding waters. Aquatic organisms, including commercial species, encounter and ingest microplastics, but there is a paucity of data about those caught and cultured in North America. Additional research is needed to determine prevalence, physiological effects, and population-level implications of microplastics in commercial species from Canada, the United States, and …

Study Group On Climate Change Recommendations Progress Report, Dano Weisbord

Year on Climate Change: Other Materials

Climate change is an urgent, complex problem. Human activities are pushing the climate beyond the range of conditions experienced over the last few million years and toward abrupt, unpredictable, highly damaging and potentially irreversible impacts. Effective responses will require ambitious, multifaceted plans of action.
