Analyzing The Ramifications Of Climate Change On Mental Health, Salvatore A. Medori
CAFE Symposium 2024
When thinking about the vast array of impacts that the climate crisis has on humanity, there are many things that come to mind, but mental health impacts are likely not one of them. Even though research demonstrates that mental effects from any form of disaster far exceed the physical health implications mental health impacts of the largest disaster facing humanity since the Second World War are rarely considered at all, let alone when solutions are being created. This has led to a hidden crisis emerging underneath an even larger crisis, with serious consequences for most individuals across the globe. The …

The Impact Of Climate Change On Selected Pnw Watersheds Through The Lens Of Western Red Cedar Habitat, Jordan T. Hamann
The Impact Of Climate Change On Selected Pnw Watersheds Through The Lens Of Western Red Cedar Habitat, Jordan T. Hamann
Dissertations and Theses
Climate change is a real phenomenon that is exacerbating existing natural processes and developing into a new normal for the planet. This change may be devastating for Pacific Northwest populations of Western Red Cedar (WRC) west of the Cascade Mountain range in the states of Oregon and Washington. WRC is a valuable tree species for reasons both economic and cultural. Dieback among WRC is following an accelerating trend. Since dieback is usually followed by tree mortality, understanding its causes and distribution is beneficial to the overall success of the species going into the future.

Under New Direction: Using Theatre To Combat The Climate Crisis, Brian Kirsch
Student Scholar Symposium Abstracts and Posters
The Earth is growing unsuitable for human society as we know it at an unprecedented rate. Among the latest in a set of increasingly grim statistics, the atmosphere’s carbon dioxide concentration is now a staggering 150% of its value for most of human history (Stein). This has triggered global warming on track to meet or exceed 1.5 degrees Celsius, which comes with extreme and irreversible changes to the planet (Jackson). However, this information fails to both command its merited attention and spark the urgent action needed to preserve our way of life. Less than half of American voters consider climate …

The Maine Question
The nation’s first multi- and inter-disciplinary research institute to study Earth’s recent and long-term climate variability was founded in 1972 at the University of Maine. That institute, now known as the Climate Change Institute, is celebrating its 50th anniversary this year, a milestone that honors the many groundbreaking discoveries its scientists have made in the field of climate science.
CCI have scientists first mapped the difference between climate during the Ice Age and today in the 1970s; discovered the importance of marine-based ice sheets in the 1980s; connected acid rain to human causes in the mid-1980s; uncovered the concept of …
Identifying New Invasives In The Face Of Climate Change: A Focus On Sleeper Populations, Ayodelé C. O'Uhuru
Identifying New Invasives In The Face Of Climate Change: A Focus On Sleeper Populations, Ayodelé C. O'Uhuru
Masters Theses
Sleeper populations are established populations of a non-native species whose population growth is limited by one or more abiotic or biotic conditions, such as climate change. While the northeastern US is predicted to be a hotspot for future invasions, identifying potential sleeper populations before they become invasive can inform proactive, climate-smart invasive species management. I focused on 169 introduced species that are established in one or more northeastern states. I used the Environmental Impact Classification for Alien Taxa (EICAT) framework to systematically identify and review the peer-reviewed literature for these candidate species to quantify their negative ecological and socioeconomic impacts. …

Quantifying Spatial Heterogeneity Of Wild Blueberries And Crop Water Stress Monitoring Using Remote Sensing Technologies, Kallol Barai
Electronic Theses and Dissertations
The wild blueberry is one of the major crops of Maine, with significant economic value and potential health benefits. Due to global climate change, drought impacts have been increasing significantly in recent years in the northeast region of the USA, causing significant economic losses in the agricultural sectors. It has been predicted to increase further in the future. Changing patterns of the elevated atmospheric temperatures, increased rainfall variabilities, and more frequent drought events have made the wild blueberry industry of Maine vulnerable, suggesting the adoption of novel approaches to mitigate the negative impacts of global climate changes. Also, wild blueberry …
Environmental Communication: Changing The Attitude-Behavioral Gap In Science Communication Utilizing Strategic Messaging, Carrie Helgeson Nelms
Environmental Communication: Changing The Attitude-Behavioral Gap In Science Communication Utilizing Strategic Messaging, Carrie Helgeson Nelms
Graduate Theses and Dissertations
National Polls in the United States consistently find the public’s beliefs and attitudes about climate change and other environmental issues significantly diverge from those held by the science community. A communication gap between the findings on the causes and effects of environmental issues and the public’s inability to interpret or refuse to accept these findings are possible causes of this divergence. This communication gap constitutes a threat to society because of inaction to environmental problems and points to needed changes in scientific messaging that better informs and motivates behavioral change. The present research employed a strategic message design to affect …

Geological Sciences Faculty Scholarship
The West Antarctic Ice Sheet (WAIS) presently holds enough ice to raise global sea level by 4.3 m if completely melted. The unknown response of the WAIS to future warming remains a significant challenge for numerical models in quantifying predictions of future sea level rise. Sea level rise is one of the clearest planet-wide signals of human-induced climate change. The Sensitivity of the West Antarctic Ice Sheet to a Warming of 2 ∘C (SWAIS 2C) Project aims to understand past and current drivers and thresholds of WAIS dynamics to improve projections of the rate and size of ice sheet …

S6e1: What Happens If Mount Everest Loses All Of Its Snow And Ice?, Ron Lisnet, Paul A. Mayewski
The Maine Question
No place on earth can escape the effects of climate change, not even Mount Everest. The highest glacier on the world’s tallest mountain — the South Col Glacier — is rapidly disappearing. A new University of Maine-led study found that the glacier is losing several decades of ice and snow accumulation annually due to human-induced climate change.
These findings are the latest from the 2019 National Geographic and Rolex Perpetual Planet Everest Expedition, led by UMaine Climate Change Institute director Paul Mayewski. In this episode of “The Maine Question,” Mayewski and UMaine Ph.D. candidate Mariusz Potocki, both co-authors of the …

Connections Between Atmospheric Blocking, General Circulation, And Weather Extremes In A Hierarchy Of Models And Various Climates, Veeshan Narinesingh
Dissertations, Theses, and Capstone Projects
The field of geophysical fluid dynamics (GFD) includes the study of both the motion and thermodynamic aspects of the atmosphere. These properties are of particular importance because they directly influence both local and large-scale weather and climate and are associated with various phenomena. One phenomena that is particularly influential is atmospheric blocking. Atmospheric blocks are persistent, quasi-stationary anticyclones (a.k.a. high-pressure systems) that occur in the atmosphere and disrupt the flow. Blocks are known to induce heat extremes and cold spells, as well as steer storms and cause numerous types of hazards. Yet despite the hazards associated with blocks, our current …
Evolution Of Drought And Low Temperature Responses In Temperate Pooideae Grasses: Timings, Determinants, And Intersections, Aayudh Das
Graduate College Dissertations and Theses
Anthropogenically-mediated rises in atmospheric CO2 and global average temperatures is leading to increasingly severe drought and extreme weather events, the latter including unseasonal bouts of low and high temperatures. In order for plant breeders and conservation biologists to predict future responses to global warming, they must understand the ecological and evolutionary processes that shaped plant tolerance to stressful environments in the past. This is particularly true for grasses (Poaceae) that dominate approximately one-third of the Earth's vegetative cover, live in some of the world's harshest terrestrial environments, and are tremendously important, both ecologically and economically. One of the largest subfamily …

S5e4: What Can Mud Reveal About The History Of Oceans?, Ron Lisnet, Katherine Allen
The Maine Question
Oceans serve as the dominant feature of the Earth. They sustain life, which began in their salty waters, and influence weather and climate.
Despite the significance of Earth’s oceans, much of their history remains a mystery. Katherine Allen, and assistant professor from the School of Earth and Climate Sciences at the University of Maine, looks to literally dig up that history, which can be found in mud along the ocean floor and the many objects embedded in it. Dredging up the record of Earth’s oceans from the seafloor requires detective work, and provides exciting adventures.

Carbon And Nitrogen Dynamics Of A Lagoon Salt Marsh In Davenport, California, Mark D. Gormley
Dissertations, Theses, and Capstone Projects
Wetlands are complex environments that play a critical role in regulating the global biogeochemical cycle of carbon (C) and nitrogen (N). Wetlands are critical contributors to global climate change and atmospheric chemistry since they store as much as 33% of the world’s soil organic carbon (SOC), release more than 20% of the atmospheric methane (CH4), and produce nitrous oxide (N2O), an extremely potent greenhouse gas (GHG). Despite the enormous radiative forcing potential of carbon dioxide (CO2), CH4 and N2O derived from wetlands, uncertainties over the rates of C sequestration and GHG …

Climate Change Preparedness In The Insurance Sector, Daniel Fischler
Honors Scholar Theses
Climate change is the inevitable consequence of human activity since the industrial revolution began centuries ago. Assuming humanity survives and adapts to this scenario, there will be significant impacts on the economy and business. Under these circumstances, the insurance sector in particular will face challenges as the frequency and severity of losses increase due to climate change related events. This paper aims to analyze various options for allowing insurance to maintain viability in this changing environment. The general issue for the future is premiums must be commensurate with climate change related risk in affected areas. As a result, certain coastal …
Climate Change Frames And Emotional Responses On Reddit, Isabel Iruani Villanueva
Climate Change Frames And Emotional Responses On Reddit, Isabel Iruani Villanueva
Graduate Theses and Dissertations
Climate change remains a highly polarized topic in the United States. Research suggests that the divide in climate change beliefs is partly a result of news media’s representation of select aspects of the problem, or framing. Frames influence individuals’ attitudes, emotions, and behaviors towards climate change. Overwhelming representation of certain climate change frames has led to a lack of emotional connection to the issue, resulting in inaction or dismissal. Climate change researchers have investigated the presence and effects of frames on both news media and select social media sites, particularly Twitter. However, little research has investigated the climate change conversation …

The most challenging of all endeavors in human history will likely be that of understanding the impact of our industrial and technological enterprises on the planet’s climate and ecosystems, and responding effectively to the threats posed by that impact. I began writing this chronology while developing a climate policy course at the University of Maine. It has grown substantially during the ensuing nine years, and continues to grow.
By juxtaposing developments in climate science, U.S. policy, and international policy over the previous two centuries, I hope to give the reader new insights into where we have been, where we are …
Estimated 2020 Co2 Emission Reductions In Virginia’S Transportation Sector From Covid-19, Eden E. Rakes, Pamela R. Grothe, Jeremy S. Hoffman
Estimated 2020 Co2 Emission Reductions In Virginia’S Transportation Sector From Covid-19, Eden E. Rakes, Pamela R. Grothe, Jeremy S. Hoffman
Virginia Journal of Science
The initial lockdown phase of the COVID-19 pandemic presented an unfortunate opportunity to observe how abrupt, large-scale changes in traffic volume can reduce greenhouse gas emissions. This study explores how carbon dioxide (CO2) emissions from Virginia’s transportation sector may have been affected by the changes in activity stemming from COVID-19 to inform more carbon-neutral policies as the state recovers from the economic downfall. Emission savings were calculated by multiplying the percent change from 2019 to 2020 in traffic volume from the Virginia Department of Transportation with the business-as-usual 2020 U.S. Environmental Protection Agency estimate of CO2 emissions …
Shaping Soil: Examining Relationships Between Agriculture And Climate Change, Lindsay Barbieri
Shaping Soil: Examining Relationships Between Agriculture And Climate Change, Lindsay Barbieri
Graduate College Dissertations and Theses
As the ripple-effects of a changing climate shape our planet, understanding relationships between agriculture and climate change is critical. With agricultural practices shaping soils on over a third of the earth’s land surface, the soils and lands where food is produced are integral grounds for examining these relationships. While not all humans practice agriculture in similar or damaging ways, nevertheless, dominant agricultural practices are displacing beings and ecosystems and perturbing global nutrient cycles across the planet. These entwined imbalances of dominance and nutrients result in flows of excess nitrogen, phosphorus, and carbon that are responsible for nearly three-fourths of the …

Changes In The Philippine Coastal Environment, Karl H. Szekielda, Ma. Aileen Leah G. Guzman
Environmental Science Faculty Publications
Global warming is progressing at a faster speed than has been estimated earlier in climate forecasting, and the ocean responds rather quickly to global temperature increase. This study uses remotely sensed data that were accessed from the System for Multidisciplinary Research and Applications (NASA Giovanni) to study environmental change in the Philippines’ coast. Monthly averaged sea surface temperature series from around the Philippines indicate that the Philippines follow the global trend in ocean temperature increase and show the increase of about 0.50C within two decades. Despite the high variability in temperature, the linear regressions displayed for all seasons show an …
Strategies For Reducing Greenhouse Gases From Liquid Dairy Manure, Vera Sokolov
Strategies For Reducing Greenhouse Gases From Liquid Dairy Manure, Vera Sokolov
Theses and Dissertations (Comprehensive)
Livestock production, including the storage, handling, and spreading of manure, are among the largest contributors to greenhouse gas emissions from the agricultural sector. Liquid dairy manure storages are hot spots of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). Both CH4 and N2O are greenhouse gases (GHG) which contribute to global warming, while NH3 is an indirect source of N2O and a risk to human health. Reducing emissions from manure storages is important not only for protection of environment and humans, but also for conserving the nutrients in …

Developing A Tourism Opportunity Index Regarding The Prospective Of Overtourism In Nepal, Susan Phuyal
MSU Graduate Theses
This research explores Nepal's overtourism scenario based on the capacity of a locality to manage sustainable tourism practices. Environmental degradation, local infrastructure degradation, negative tourist experience and local resident responses regarding visitors are the four main variables used in this study to analyze overtourism. In order to analyze the case study of overtourism, we select the three top touristic cities of Nepal, Kathmandu, Pokhara, and Chitwan based on the number of annual visitors. Nepal's case analysis of overtourism conditions reviews the overall threat of over-tourism and establishes a metric by which tourism can be viewed as potentially detrimental to sustainability. …
