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 …

The Impacts Of Climate Change On The World’S Economic, Political, And Demographic Structures, Dino Kanlic

Arts & Sciences Electronic Theses and Dissertations

Climate change will have negative impacts on the political, economic, and demographic structures of society. These include a rise in ethnic tensions in the Indian Sub Continent, massive immigration to Europe, regional economic collapse and political destabilization in Africa, the inundation of island nations and economic losses in the Americas among many other changes which will combine to destabilize humanity for generations. International affairs has failed to come up with a solution because global warming is a universal prevention focused problem that trades short term gains for long term losses. Global warming will be solved by the onset of grid …

Modeling Mussel Mortality: Investigating The Importance Of Swash And The Potential Implications Of Changing Wave Environments, Shadow Leigh Gulledge

Theses and Dissertations

Rising sea level and increases in temperature are causing biogeographic shifts in intertidal zones and can also lead to shifts in the local vertical zonation of organisms due to changes in body temperature during aerial exposure during low tide. Swash is an important determinant of aerial body temperatures, and vulnerability of intertidal zones to changes in climate could potentially depend on how much and how often animals are cooled by waves. While wave heights (and thus swash) are generally expected to increase with climate change, anthropogenic physical structures, such as breakwaters and wave energy converters, can decrease wave height and …

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 …

Cultivating Communities Of Practice To Develop Local Preparedness For Climate Change, Konda Reddy Chavva

Doctoral Dissertations

The goal of this research was to study the effectiveness of field facilitators’ (FFs) community of practice in improving ways in which FFs and farmers communicate and work together to strengthen farmers’ climate change preparedness through identifying locally suitable adaptation strategies in drought-prone districts of Andhra Pradesh State in India. In development initiatives like the one studied, FFs are often the key liaison person with each community—farmers in this case. FFs interact regularly with farmers, with whom they establish and sustain critical relationships over time. Further, they take the lead in building farmers’ capacities by contextualizing technical information that professionals …

Planning For Adaptation To Climate Change: Lessons From The Us National Wildlife Refuge System, Robert L. Fischman, Vicky J. Meretsky, Alexei Babko, Michael Kennedy, Lei Liu, Michelle Robinson

Articles by Maurer Faculty

US national wildlife refuges have recent, detailed management plans illustrating the state of planning for climate-change adaptation in protected areas. Discussion of and prescriptions for addressing climate change increased in refuge plans between 2005 and 2010 but decreased in 2011. The plans respond to some climate-change impacts on biodiversity and call for monitoring but with little clarity regarding how to act on monitoring results and scant attention to future changes in phenology and community composition. The threats posed by sea-level rise generated the best-developed plan prescriptions. Examples of excellent prescriptions provide models for future planning. Some decision-support tools, such as …

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 …

Sustainability Planning, Environmental Justice And Climate Change: Applications Of The Long Island Markal Model, David S. Friedman, Yehuda Klein, Jose Pillich, Michael T. Sullivan

Suburban Sustainability

As pointed out by many authors, sustainability is often vague and amorphous (See, for example, Dovers, 1989; Faber, et al, 2005; Glavič, et al. 2007). There is a clear need to make analytical and data-driven analyses of established and or proposed plans. MARKAL (MARKet ALlocation model) is an analytical tool that can be used characterize the impacts of sustainability plans at multiple spatial scales: global, national, regional, and local. In this study we apply the Long Island MARKAL model to answer three interrelated issues: 1, the development and incremental improvement of local and regional sustainability plans; 2, the impact of …

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 …

Optimized Method For Black Carbon Analysis In Ice And Snow Using The Single Particle Soot Photometer, I. A. Wendl, James A. Menking, R. Färber, M. Gysel, Susan D. Kaspari, M. J. G. Laborde, M. Schwikowski

All Faculty Scholarship for the College of the Sciences

In this study we attempt to optimize the method for measuring black carbon (BC) in snow and ice using a Single Particle Soot Photometer (SP2). Beside the previously applied ultrasonic (CETAC) and Collison-type nebulizers we introduce a jet (Apex Q) nebulizer to aerosolize the aqueous sample for SP2 analysis. Both CETAC and Apex Q require small sample volumes (a few milliliters) which makes them suitable for ice core analysis. The Apex Q shows the least size-dependent nebulizing efficiency in the BC particle diameter range of 100–1000 nm. The CETAC has the advantage that air and liquid flows can be monitored …

Seasonal And Elevational Variations Of Black Carbon And Dust In Snow And Ice In The Solu-Khumbu, Nepal And Estimated Radiative Forcings, Susan Kaspari, T. H. Painter, M. Gysel, S. M. Skiles, M. Schwikowski

All Faculty Scholarship for the College of the Sciences

Black carbon (BC) and dust deposited on snow and glacier surfaces can reduce the surface albedo, accelerate snow and ice melt, and trigger albedo feedback. Assessing BC and dust concentrations in snow and ice in the Himalaya is of interest because this region borders large BC and dust sources, and seasonal snow and glacier ice in this region are an important source of water resources. Snow and ice samples were collected from crevasse profiles and snow pits at elevations between 5400 and 6400 m a.s.l. from Mera glacier located in the Solu-Khumbu region of Nepal during spring and fall 2009, …

Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes

The Summer Undergraduate Research Fellowship (SURF) Symposium

Climate change and increases in nitrogen deposition impact ecosystems globally. Projected atmospheric warming allows rain to fall in larger events with longer dry periods in between, increasing rainfall variability in many regions. Concurrently, the combustion of fossil fuels and the heavy use of nitrogen fertilizers continue to increase the availability of nitrogen globally. However, not much is known about how these global change factors, increased rainfall variability and nitrogen deposition, interact with each other to affect ecosystem functions, particularly belowground where root production contributes to soil carbon pools- an important component in regulating climate. In order to study these factors, …

Impacts Of Climate Change On The Evolution Of The Electrical Grid, Melissa Ree Allen

Doctoral Dissertations

Maintaining interdependent infrastructures exposed to a changing climate requires understanding 1) the local impact on power assets; 2) how the infrastructure will evolve as the demand for infrastructure changes location and volume and; 3) what vulnerabilities are introduced by these changing infrastructure topologies. This dissertation attempts to develop a methodology that will a) downscale the climate direct effect on the infrastructure; b) allow population to redistribute in response to increasing extreme events that will increase under climate impacts; and c) project new distributions of electricity demand in the mid-21^st century.

The research was structured in three parts. The first …

International Conference on Hydroinformatics

Observed daily rainfall data during baseline period i.e. 1961-1990 of four raingauge stations namely Akluj, Baramati, Bhor and Malsiras located in the Nira River basin in Central India were analyzed to study the impact of climate change on rainfall. LARS-WG incorporating 15 GCM’s from the CMIP3 predictions for A1B, A2 and B1 emission scenarios was used to statistically downscale the daily rainfall data during three time spans centred at 2020’s, 2055’s and 2090’s. Uncertainty in GCMs rainfall predictions was analyzed on monthly, seasonal and annual scales. Kolmogorov-Smirnov test, Student’s t-test, and Fisher test have shown average to good performance during …

The Effect Of Flood Reduction And Water Conservation Of Decentralized Rainwater Management System, Dong Geun Kwak, Moo Young Han

International Conference on Hydroinformatics

Climate change and increase of surface runoff by urbanization caused the urban flooding. Therefore, a sustainable new paradigm is required to recover sound water circulation and overcome the limitations of the existing water management system vulnerable to flooding. Recently Rainwater management is widely known and its legal obligation is strengthened to improve the control capacity for flooding reduction and water conservation in urban areas. Multipurpose DRMS(Decentralized Rainwater Management System) is a new paradigm proposed and recommended by NEMA(National Emergency Management Agency) for both flood control and water conservation. In this study, a flood prone area in Suwon of South Korea …

A Spatial-Temporal Downscaling Approach To Construction Of Rainfall Intensity-Duration-Frequency Relations In The Context Of Climate Change, Van-Thanh-Van Nguyen, Myeong-Ho Yeo

International Conference on Hydroinformatics

This paper proposes a spatial-temporal downscaling approach to construction of the intensity-duration-frequency (IDF) relations at a local site in the context of climate change and variability. More specifically, the proposed approach is based on a combination of a spatial downscaling method to link large-scale climate variables given by General Circulation Model (GCM) simulations with daily extreme precipitations at a site and a temporal downscaling procedure to describe the relationships between daily and sub-daily extreme precipitations based on the scaling General Extreme Value (GEV) distribution. The feasibility and accuracy of the suggested method were assessed using rainfall data available at eight …

The Application Of A Dynamic Openmi Coupling Between A Regional Climate Model And A Distributed Surface Water-Groundwater Model, Michael Brian Butts, Martin Drews, Morten Andreas Dahl Larsen, Sara Lerer, Søren Højmark Rasmussen, Jesper Grooss, Jesper Overgaard, Jens Christian Refsgaard

International Conference on Hydroinformatics

The understanding of interactions between the atmosphere, the land surface and the subsurface hydrology plays a key role in ensuring sustainable development of water resources and terrestrial ecosystems. The evaluation of climate adaptation measures requires the ability to reliably simulate the impact of different anthropogenic effects such as changes in land use, interventions such as reservoirs for flood control and irrigation, conjunctive use of surface water and groundwater under projections of future climatic conditions and variability. The interaction between climate and groundwater are often neglected in climate models and climate assessment and few studies have investigated how groundwater systems will …

Hydrological Impacts Of Climate Change – Challenges, Uncertainty And Limitations, Shreedhar Maskey, Yurong Hu, Anshul Agarwal, Dinesh Bhatt

International Conference on Hydroinformatics

How climate change impacts water resources in the future is an important question that all hydrologists want to have an answer. Climate prediction scenarios are available from many Global Circulation Models for the 21st century. These prediction datasets are typically used as input to a hydrological model for simulating impacts on hydrology, particularly river runoff, evaporation, and storage changes. Because hydrological models are usually run on a much smaller resolutions than climate models, the climate prediction datasets are usually downscaled to represent local climate for using in a hydrological model. The uncertainty in the GCMs, downscaling and hydrological models makes …
