Mitigating The Effects Of Climate Change With Wind Energy And Gis, Rachael Isphording, Richard Snow, Mary Snow

Publications

The climate is changing, and humans are heavily exacerbating these changes. As the effects of climate change are being felt across the planet, scientists and policy makers are uniting to increase mitigation efforts and are researching renewable, clean energy sources to reduce the amount of greenhouse gas emissions released into the atmosphere during energy production. Of the different renewable energy technologies, wind energy is one of the most researched and implemented. Over the past twenty years, researchers have been applying Geographic Information Systems (GIS) to their climate change studies. GIS allows the user to spatially view, manipulate, and analyze data …


Virginia Accomplishments Since The 2008 Climate Action Plan Release, Center For Coastal Resources Management, Virginia Institute Of Marine Science Dec 2014

Virginia Accomplishments Since The 2008 Climate Action Plan Release, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

Virginia has undertaken a variety of actions to mitigate the emission of greenhouse gasses and adapt to climate related changes to our weather, wildlife, and sea level. However, these changes have not been undertaken in a coordinated fashion, nor have they been in clear response to the recommendations of any entity that has approached the problem of climate change as a whole. Greenhouse gas mitigation has taken place in the form of a few policies to capture landfill gas, encourage limited energy efficiency, encourage growth of some renewable energy, and reduce vehicle miles traveled. Additionally, good progress has been made …


Potential Effects Of Changing Climate On The Physical, Chemical, And Biological Characteristics Of Alpine Lakes, Uinta Mountains, Utah, Usa, Shirley Ngai Oct 2014

Potential Effects Of Changing Climate On The Physical, Chemical, And Biological Characteristics Of Alpine Lakes, Uinta Mountains, Utah, Usa, Shirley Ngai

Electronic Thesis and Dissertation Repository

Relationships between climate variables, lake characteristics and diatom community composition were determined for five lakes in the Uinta Mountains, Utah (USA) from spring 2010 to autumn 2013 to provide information to help predict the effects of climate change on lake ecosystems. Surface water temperatures increased with decreasing elevation although microclimates affected this relationship. Deeper water temperatures increased or stayed the same with increasing elevation, probably due to greater transparency or convective heating. Total phosphorus (TP) and chl a concentrations decreased in the spring/summer with warmer fall/winter temperatures, and nitrates in the spring increased with increased fall/winter precipitation. A significant correlation …


Warming, Competition, And Bromus Tectorum Population Growth Across An Elevation Gradient, Aldo Compagnoni, Peter B. Adler Sep 2014

Warming, Competition, And Bromus Tectorum Population Growth Across An Elevation Gradient, Aldo Compagnoni, Peter B. Adler

Green Canyon Environmental Research Area, Logan Utah

Cheatgrass (Bromus tectorum) is one of the most problematic invasive plant species in North America and climate change threatens to exacerbate its impacts. We conducted a two‐year field experiment to test the effect of warming, competition, and seed source on cheatgrass performance across an elevation gradient in northern Utah. We hypothesized that warming would increase cheatgrass performance, but that warming effects would be limited by competing vegetation and by local adaptation of cheatgrass seed sources. The warming treatment relied on open top chambers, we removed vegetation to assess the effect of competition from neighboring vegetation, and we reciprocally …


Climate Change And Forest Fires Synergistically Drive Widespread Melt Events Of The Greenland Ice Sheet, Kaitlin M. Keegan, Mary R. Albert, Joseph R. Mcconnell, Ian Baker Jun 2014

Climate Change And Forest Fires Synergistically Drive Widespread Melt Events Of The Greenland Ice Sheet, Kaitlin M. Keegan, Mary R. Albert, Joseph R. Mcconnell, Ian Baker

Dartmouth Scholarship

In July 2012, over 97% of the Greenland Ice Sheet experienced surface melt, the first widespread melt during the era of satellite remote sensing. Analysis of six Greenland shallow firn cores from the dry snow region confirms that the most recent prior widespread melt occurred in 1889. A firn core from the center of the ice sheet demonstrated that exceptionally warm temperatures combined with black carbon sediments from Northern Hemisphere forest fires reduced albedo below a critical threshold in the dry snow region, and caused the melting events in both 1889 and 2012. We use these data to project the …


Late Glacial-Holocene Climate Change Recorded In Proglacial Lake Sediment Cores From The Huaguruncho Massif, Central Peruvian Andes, Dane O'Neil Jun 2014

Late Glacial-Holocene Climate Change Recorded In Proglacial Lake Sediment Cores From The Huaguruncho Massif, Central Peruvian Andes, Dane O'Neil

Honors Theses

Alpine glaciers respond rapidly to changes in climate and the growth and decay of alpine glaciers is recorded in sediment cores extracted from lakes immediately downvalley from the margins of former glaciers. These records provide continuous archives of glaciation and climate change that complement the inherently discontinuous records of glaciation preserved by moraines. The aim of this study is to generate a continuous record of glaciation in Jaico cirque from lake sediment cores, which is located on the southeastern side of the quartz-monzonite dominated Huaguruncho Massif (5789 masl) in the eastern Peruvian Andes. The lakes are Laguna Jaico (10.56° S, …

Risky Business: Recommendations For The Insurance Industry To Contribute To Greater Disaster Risk Reduction And Climate Change Adaptation, Jessie G. Rountree

Master's Projects and Capstones

The private insurance industry is susceptible to increasing risk from climate change and can serve as a catalyst to change behavior to minimize loss. The research examined the current impact and future potential of the insurance industry to reduce both physical and financial risk. The insurance industry currently raises awareness, assigns an economic value to risk, advocates for climate change action, and takes measures to reduce physical risk through mitigation. As well, the industry has proven to be a critical influencer to encourage risk-adverse behavior and regulation. Recommendations to the industry to have a greater impact include: 1) pursue more …

The Sustainability Institute Publications

EARTH’S CLIMATE CHANGES. It always has and always will. However, an extensive and growing body of scientific evidence indicates that human activities—including the burning of fossil fuel (coal, oil, and natural gas) for energy, clearing of forested lands for agriculture, and raising livestock—are now the primary force driving change in the Earth’s climate system. This report describes how the climate of northern New Hampshire has changed over the past century and how the future climate of the region will be affected by a warmer planet due to human activities.

Warming, Soil Moisture, And Loss Of Snow Increase Bromus Tectorum’S Population Growth Rate, Aldo Compagnoni, Peter B. Adler Jan 2014

Warming, Soil Moisture, And Loss Of Snow Increase Bromus Tectorum’S Population Growth Rate, Aldo Compagnoni, Peter B. Adler

Green Canyon Environmental Research Area, Logan Utah

Climate change threatens to exacerbate the impacts of invasive species. In temperate ecosystems, direct effects of warming may be compounded by dramatic reductions in winter snow cover. Cheatgrass (Bromus tectorum) is arguably the most destructive biological invader in basins of the North American Intermountain West, and warming could increase its performance through direct effects on demographic rates or through indirect effects mediated by loss of snow. We conducted a two-year experimental manipulation of temperature and snow pack to test whether 1) warming increases cheatgrass population growth rate and 2) reduced snow cover contributes to cheatgrass’ positive response to …


Rising Waters: Local Implications And Actions, Laura Sorrentino, Angelo Spillo Jan 2014

Rising Waters: Local Implications And Actions, Laura Sorrentino, Angelo Spillo

Student-Faculty Research Projects

According to Mark Lowery, Climate Policy Analyst for the New York State Department of Environmental Conservation, climate change influences warmer water, causing the oceans to take up more space and causing a higher percentage of water vapor in the atmosphere, which creates more powerful storms. That being said, it is evident that climate change has contributed to rising sea levels and more intense storms so it is important to understand the dangers associated with this issue and what possible options exist to minimize its impacts.

Our research investigates the threat of rising waters in the lower New York coastal region …

The Grand Thaw: Our Vanishing Cryosphere, Richard Snow, Mary Snow

Publications

Records reveal that beginning in the 1950s there has been an accelerated reduction in ice and snow across most mountain glaciers and ice caps. The glaciers of the Tibetan Plateau and the Himalayan Mountains are the main source of water for the Ganges and the Indus Rivers. During the summer higher temperatures are causing these glaciers to melt at an increasing rate while during the winter the warmer temperature are yielding a dearth of snowfall, which in turn leads to drought. Along the equator in Africa, glaciers are faced with a similar same situation. In Uganda, 80 percent of the …

Climate Change: The Proof And The Process, Richard Snow, Mary Snow

Publications

Since what we call civilization began some 12,000 years ago, the mean temperature of Earth has not varied more than 1°C from the average. The forecast change in temperature of from 1.5 to 4°C (2.7 to 7°F) by 2100 has no equal in the recent history of the planet. Changes in the energy output of the sun, changes in the relative position of the sun and Earth, shifting locations of the continents, mountain building, volcanic eruptions, and changes in atmospheric composition all combine to cause our climate to change. Most of the changes in climate of the past can be …


Changing The Climate Narrative: How A Long-Term Climate Change Might Save Our Lives, Natalie P. Harreld Jan 2014

Changing The Climate Narrative: How A Long-Term Climate Change Might Save Our Lives, Natalie P. Harreld

CMC Senior Theses

The goal of this paper is to offer new insights into the climate change debate by shifting away from the heated anthropologic arguments that dominate politics, media, and popular science. Instead, I choose to rely on the long-term impacts of a changing climate on our planet. The paper begins with a break down of key processes involved in short-term and long-term climate change, using the latest research. After a foundational understanding of climate sciences is established, we will discuss the failure of the climate change debate in educating the general public about the facts of a changing climate. Finally, the …
