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.

In this episode of “The …

Impacts Of Climate Change In Vulnerable Communities In Sindh, Pakistan: Voices From The Community, Kiren Khan, Mumraiz Khan, Tahira Parveen, Sabahat Hussain

Climate and Environmental Changes

Pakistan ranks among the ten countries worst affected by climate change in the world, and within the country the province of Sindh is one of the hardest-hit regions. Changing trends in temperature and precipitation have increased the frequency and severity of hazards such as flooding, droughts, and heatwaves, among a host of other environmental stresses. The present qualitative study was conducted to scope out the specific ways in which the impacts of climate change are gendered among rural communities in Sindh that have the highest exposure to hazards arising from climate change. The study probed the perceptions and experiences of …

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

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 …

A Climate Chronology, Sharon S. Tisher

School of Economics Faculty Scholarship

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

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 …

Vims Hydrofile: Ambient Water Monitoring And Meteorological Data For Chesapeake Bay And Near Coastal Shelf Waters, 1942-1982, Gary F. Anderson

Data

Historical ambient water quality and meteorologic conditions from cruises conducted by the Virginia Institute of Marine Science in Chesapeake Bay and nearshore coastal shelf waters over a 40-year period through 1982.

Bulk water parameters were routinely measured during cruises conducted in Chesapeake Bay and nearshore coastal waters conducted by VIMS over four decades. Data were punched on 80-character cards known as ‘Form 1’ format by the VIMS central Computer Center. These were later converted to digital files. For this publication the Form 1 files were unpacked into yearly flat files containing two record types:

Station records - Contain surface observations …

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 …

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 …

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 …
