Radiative Forcing By Dust And Black Carbon On The Juneau Icefield, Alaska, Sonia A. Nagorski, Susan D. Kaspari, Eran Hood, Jason B. Fellman, S. Mckenzie Skiles

All Faculty Scholarship for the College of the Sciences

Here we present the first known data set on black carbon (BC) and mineral dust concentrations in snow from the Juneau Icefield (JIF) in southeastern Alaska, where glacier melt rates are among the highest on Earth. In May 2016, concentrations of BC (0.4–3.1 μg/L) and dust (0.2–34 mg/L) were relatively low and decreased toward the interior of the JIF. The associated radiative forcing (RF) averaged 4 W/m2. In July, after 10 weeks of exposure, the aged snow surface had substantially higher concentrations of BC (2.1–14.8 μg/L) and dust (11–72 mg/L) that were not spatially distributed by elevation or distance from …

Climate In Architecture: Revision Of Early Origins, Ursula Anna Freire Castro

Latin American Studies ETDs

This dissertation expands the comprehension of the history of climate in architecture by examining the evolution of the architectural meanings, uses, representations, and simulations of climate between 1800 and the present by means of a historical critical analysis of two scientific artifacts that attempted to model climate for the first time in the fields of geography and architecture. The Naturgemälde (1799 – Alexander von Humboldt) was a type of infographic image that simulated conceptually climate as a global system. The Climatron (1954 – Victor Olgyay) was a laboratory machine that physically simulated climate to test building scaled-models.

Primary data was …

Establishing Relationships Between Drought Indices And Wildfire Danger Outputs: A Test Case For The California-Nevada Drought Early Warning System, Daniel J. Mcevoy, Mike Hobbins, Timothy J. Brown, Kristin Vander Molen, Tamara Wall, Justin L. Huntington, Mark D. Svoboda

National Drought Mitigation Center: Faculty Publications

Relationships between drought indices and fire danger outputs are examined to (1) incorporate fire risk information into the National Integrated Drought Information System California–Nevada Drought EarlyWarning System and (2) provide a baseline analysis for application of drought indices into a fire risk management framework. We analyzed four drought indices that incorporate precipitation and evaporative demand (E0) and three fire indices that reflect fuel moisture and potential fire intensity. Seasonally averaged fire danger outputs were most strongly correlated to multi-scalar drought indices that use E0 (the Evaporative Demand Drought Index (EDDI) and the Standardized Precipitation Evapotranspiration Index (SPEI)) at approximately annual …

Beach Composition Preferences For Nesting Populations Of Leatherback Sea Turtles (Dermochelys Coriacea), Armila Beach, Guna Yala Comarca, Scott Campbell

Independent Study Project (ISP) Collection

Sea turtles play a critical role in marine ecosystems all over the world, including the Caribbean Sea. However, many sea turtle species are under threat due to anthropogenic impacts, such as habitat destruction and fisheries bycatch. This has caused significant declines in sea turtle populations around the world, which in turn has impacted marine ecosystems where sea turtles play critical roles in proper ecosystem functioning. A crucial part of the sea turtle life cycle that has been threatened by anthropogenic factors is nesting. Sea turtles rely on unspoiled beaches with particular physical characteristics for laying their eggs. One of the …

Avian Upsloping In The Tropics: Myioborus Miniatus And Myioborus Torquatus Abundance In Different Altitudinal Ranges In Boquete, Chiriquí, Panama, Julie Yoon

Independent Study Project (ISP) Collection

Direct and indirect effects of warming global temperatures due to climate change are known to cause upwards shifts of the altitudinal ranges of some avian species. Most susceptible to this trend and at risk of riding the “escalator to extinction” are endemic species in tropical montane cloud forests, such as Myioborus torquatus. There are abiotic factors, like temperature, and biotic interactions, such as the presence of its altitudinal neighbor Myioborus miniatus, that limit the altitudinal range of this bird species in the Neotropics. This study measured abundance of M. miniatus and M. torquatus populations at different altitudinal ranges by point …

“In Principle” Versus “In Reality”: Assessing The Potential Of Adaptive Urban Governance Toward Urban Flooding In Ho Chi Minh City’S District 7, Cindy Pham Nguyen

Independent Study Project (ISP) Collection

Flooding has become the new normal in Ho Chi Minh City (HCMC). During the rainy season, many areas of the city experience severe inundation that seriously impacts infrastructure, traffic, and economic transactions. As the effects of climate change unpredictably and rapidly manifest in Southern Vietnam, the frequency and impact of urban floods are projected to increase. In addition, within the last few decades, HCMC has rapidly developed and urbanized, transforming itself into the economic center of Southern Vietnam. However, previous studies and international experts have determined that rapid, poor development may be exacerbating urban flood issues.

In recent years, city …

Life Events Which Motivate Youth To Become Climate Activists In Sydney And Canberra, Phoebe Dolan

Independent Study Project (ISP) Collection

Climate activism is the tool of young people to rise and fight for their future and the future of the planet. Today it is necessary that young people engage as climate activists. My research asks what life events motivate youth to become climate activists. I looked into the initial life events which spark the motivation of young people to understand their initial motives for joining the climate movement. I looked into where the motivation came from, a concern for nature, a concern for social justice or the interconnectedness of the two. I also looked into the life events of individuals …

Regenerative Grazing And The Benefits Of Livestock On Soils In Northern New South Wales, Raymond Mooney

Independent Study Project (ISP) Collection

Conventional cattle grazing has received criticism for environmental degradation in the past. Regenerative grazing and the principles of regenerative agriculture show encouraging signs that proper livestock management and planned grazing can reverse degradation and mitigate climate change. An emphasis on soil health and increasing soil carbon and organic matter levels reveals positive feedback for environmental health, the economic security of farmers, and nutritional health of consumers.

In this study I looked to investigate the benefits of regenerative agriculture, reasons why it is being practiced, and the extent it is practiced within the grazing in comparison to traditional methods within Northern …

Kanjirowa Blues: An Exploration Of Environmental And Climate Consciousness In Lower Dolpa, Nepal, Casey Greenleaf

Independent Study Project (ISP) Collection

It has been scientifically demonstrated that high altitude, mountainous regions such as the Himalayas are extremely susceptible to and at accelerated risk of the effects of climate change. The regions of Lower Dolpa discussed in this work, Juphal, Dunai, Chun, and Dapu, lie in a glacial watershed, and are at present risk of landslides, floods, wildfires, and rely on agricultural and transhumant livelihoods that are uniquely susceptible to the impacts of changing temperature and weather patterns. People in this region are being forced to incrementally adapt and reframe their understanding of their surroundings due to both aforementioned severe events as …

An Assessment Of Coral Bleaching Near Misali Island, Tanzania, Danielle Kulick

Independent Study Project (ISP) Collection

Coral bleaching and reef health were studied in fringing reefs around Misali Island, Tanzania. Over a 28-day period, 1,329 coral colonies were surveyed along 31 transects. For each colony, data was collected on growth form and bleaching severity. No significant differences in bleaching frequency or intensity were observed between the resource extraction and non-extraction zones protected under the Pemba Channel Marine Conservation Area (PECCA). Bleaching was observed to be extensive across all coral growth forms and was found to collectively increase over the study period in frequency and intensity. This study indicates the vulnerability of Misali coral reefs to bleaching …

Iceland's Migratory Birds In Changing Environmental Conditions: An Interactive Synthesis, Frances J. Duncan

Independent Study Project (ISP) Collection

Human-driven changes to environmental conditions alter the habitats, behaviors, and migration patterns of migratory species. Changes in temperature, vegetation, and precipitation are just some of the factors contributing to shifts in phenology, demography, and distribution of migratory birds. These changes are driven by anthropogenic climate change and amplified by human land-use change, and are especially intense at high latitudes. This project creatively communicates the effects of environmental changes on three species of migratory birds in Iceland—the northern wheatear, the Greenland white-fronted goose, and the black-tailed godwit—using principles of storytelling and game design. The resulting interactive product is a game that …

Eating Some Invasive Species Could Help To Mitigate The Impacts Of Climate Change-Related Invasions, And May Increase Future Food Security, Jesse Bull Saffeir

Independent Study Project (ISP) Collection

Climate change is predicted to increase the spread and abundance of invasive species and to erode global food security. I hypothesized that by incorporating edible invasive species into local food sheds, these two problems could help to mitigate each other. I set out to answer two questions: could eating invasive species reduce their spread and abundance? And could eating invasive species minimize the impacts of climate-change related food shocks? To answer these questions, I surveyed the existing literature on human consumption of invasive species, created a list of criteria that make an invasive species suitable for management through human consumption, …

Mixed Responses To Woody Encroachment In Icelandic Herbaceous Plant Morphology And Phenology, Cait Battle-Mcdonald

Independent Study Project (ISP) Collection

Climate change and afforestation efforts are promoting tree growth into traditionally treeless locations in Iceland. This study examined this woody encroachment’s effect on the phenology and morophology of eight plants (Agrostis aequivalvis, Equisetum pratense, Equisetum arvense, Alchemilla alpina, Ranunculus acris, Lupinus nootkatensis, Anthriscus sylvestris, and Taraxacum sp.) in Kjarnaskógur forest, Akureyri, Iceland. An initial transplantation experiment testing trees’ effect on A. aequivalvis, E. pratense, R. acris, and A. sylvestris failed due to plant death. A subsequent observational study examined trees’ effect on E. pratense, A. alpina, R. acris, L. nootkatensis, A. sylvestris, and Taraxacum by observing morphological characteristics (leaf size, …

Environmental Consciousness For The Politically Autonomous: The Basque Country, Miranda L. White

Independent Study Project (ISP) Collection

When discussing the issue of political autonomy, the usual topics that are taken into consideration are based around human rights, language, culture, society or economics. Those are the most commonly discussed for good reason, as they are important for the rights and freedoms of a community itself. However, this research paper aims to investigate further into the discussion of the environmental effects of political autonomy in Spain, specifically in the matter of autonomous competencies for waterway and air management. Therefore, in order to test such a hypothesis, this study will use the Basque Country of Spain as the subject, and …

Rates Of Relative Sea Level Rise Along The United States East Coast, Jesse N. Beckman, Joseph E. Garcia

Virginia Journal of Science

Recent studies have indicated that some coastal areas, including the East Coast of the United States, are experiencing higher rates of sea level rise than the global average. Rates of relative sea level rise are affected by changes in ocean dynamics, as well as by surface elevation fluctuations due to local land subsidence or uplift. In this study, we derived long-term trends in annual mean relative sea level using tide gauge data obtained from the Permanent Service for Mean Sea Level for stations along the United States East Coast. Stations were grouped by location into the Northeast, Mid-Atlantic, and Southeast …

Detecting Change: Observations Of Temperature And Precipitation Across Virginia’S Climate Divisions, Jeremy S. Hoffman, Michael J. Allen, Christopher F. Labosier

Virginia Journal of Science

Modern global climate change is primarily attributable to human activities and the release of greenhouse gases into the atmosphere. Climate change impacts span a range of sectors, including agriculture, forestry, public health, and water resource management. The Commonwealth of Virginia has already and will continue to deal with many of these impacts, yet lacks concentrated effort to detect, document, and adapt to local climate changes. This study documents observed changes in temperature and precipitation across Virginia’s six climate divisions. Mean seasonal anomalies of minimum temperature, maximum temperature, and precipitation from 1986 to 2016 are examined relative to a long-term 1895-2000 …
