Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha Dec 2013

Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha

Journal of Marine Science and Technology–Taiwan

The main cause of annual fluctuations in catch and species composition of fisheries is usually uncertain, but a prevailing view has been that fishing effects are more critical than environmental variability. Filefish is a good anecdote: many Korean fisheries scientists have attributed the sudden collapse of Korean filefish fisheries in the early 1990s to overfishing, especially by trawl fisheries in the northern East China Sea (NECS). However, interdisciplinary researches have revealed that climate-driven, multi-decadal variability in oceanic conditions impacts both fish and fisheries around the world. To test the two alternative hypotheses (i.e., fishing and climate) as the major cause …

Four Decades Of Andean Timberline Migration And Implications For Biodiversity Loss With Climate Change, David A. Lutz, Rebecca L. Powell, Miles R. Silman Sep 2013

Four Decades Of Andean Timberline Migration And Implications For Biodiversity Loss With Climate Change, David A. Lutz, Rebecca L. Powell, Miles R. Silman

Dartmouth Scholarship

Rapid 21st-century climate change may lead to large population decreases and extinction in tropical montane cloud forest species in the Andes. While prior research has focused on species migrations per se, ecotones may respond to different environmental factors than species. Even if species can migrate in response to climate change, if ecotones do not they can function as hard barriers to species migrations, making ecotone migrations central to understanding species persistence under scenarios of climate change. We examined a 42-year span of aerial photographs and high resolution satellite imagery to calculate migration rates of timberline–the grassland-forest ecotone–inside and outside of …

Evidence For 20th Century Climate Warming And Wetland Drying In The North American Prairie Pothole Region, Brett A. Werner, W. Carter Johnson, Glenn R. Guntenspergen Sep 2013

Evidence For 20th Century Climate Warming And Wetland Drying In The North American Prairie Pothole Region, Brett A. Werner, W. Carter Johnson, Glenn R. Guntenspergen

Natural Resource Management Faculty Publications

The Prairie Pothole Region (PPR) of North America is a globally important resource that provides abundant and valuable ecosystem goods and services in the form of biodiversity, groundwater recharge, water purification, flood attenuation, and water and forage for agriculture. Numerous studies have found these wetlands, which number in the millions, to be highly sensitive to climate variability. Here, we compare wetland conditions between two 30-year periods (1946–1975; 1976–2005) using a hindcast simulation approach to determine if recent climate warming in the region has already resulted in changes in wetland condition. Simulations using the WETLANDSCAPE model show that 20th century climate …

Dynamical Downscaling Projections Of Twenty-First-Century Atlantic Hurricane Activity: Cmip3 And Cmip5 Model-Based Scenarios, Thomas R. Knutson, Joseph J. Sirutis, Gabriel A. Vecchi, Stephen Garner, Ming Zhao, Hyeong-Seog Kim, Morris Bender, Robert E. Tuleya, Isaac M. Held, Gabriele Villarini Sep 2013

Dynamical Downscaling Projections Of Twenty-First-Century Atlantic Hurricane Activity: Cmip3 And Cmip5 Model-Based Scenarios, Thomas R. Knutson, Joseph J. Sirutis, Gabriel A. Vecchi, Stephen Garner, Ming Zhao, Hyeong-Seog Kim, Morris Bender, Robert E. Tuleya, Isaac M. Held, Gabriele Villarini

CCPO Publications

Twenty-first-century projections of Atlantic climate change are downscaled to explore the robustness of potential changes in hurricane activity. Multimodel ensembles using the phase 3 of the Coupled Model Intercomparison Project (CMIP3)/Special Report on Emissions Scenarios A1B (SRES A1B; late-twenty-first century) and phase 5 of the Coupled Model Intercomparison Project (CMIP5)/representative concentration pathway 4.5 (RCP4.5; early- and late-twenty-first century) scenarios are examined. Ten individual CMIP3 models are downscaled to assess the spread of results among the CMIP3 (but not the CMIP5) models. Downscaling simulations are compared for 18-km grid regional and 50-km grid global models. Storm cases from the regional model …

Climate Change Impacts On Streamflow And Subbasin- Scale Hydrology In The Upper Colorado River Basin, Darren L. Ficklin, Edwin P. Maurer, Iris T. Stewert Aug 2013

Climate Change Impacts On Streamflow And Subbasin- Scale Hydrology In The Upper Colorado River Basin, Darren L. Ficklin, Edwin P. Maurer, Iris T. Stewert

Civil, Environmental and Sustainable Engineering

In the Upper Colorado River Basin (UCRB), the principal source of water in the southwestern U.S., demand exceeds supply in most years, and will likely continue to rise. While General Circulation Models (GCMs) project surface temperature warming by 3.5 to 5.6uC for the area, precipitation projections are variable, with no wetter or drier consensus. We assess the impacts of projected 21st century climatic changes on subbasins in the UCRB using the Soil and Water Assessment Tool, for all hydrologic components (snowmelt, evapotranspiration, surface runoff, subsurface runoff, and streamflow), and for 16 GCMs under the A2 emission scenario. Over the GCM …

There's A Pattern Here: The Case To Integrate Environmental Security Into Homeland Security Strategy, James D. Ramsay May 2013

There's A Pattern Here: The Case To Integrate Environmental Security Into Homeland Security Strategy, James D. Ramsay

Applied Aviation Sciences - Daytona Beach

The time is long overdue to acknowledge that global climate and resource stresses, encompassed by the concept of environmental security (ES), are an increasingly important part of "homeland" security (HS) study and practice, by even the most restricted definitions of HS. Environmental security issues will affect global economic and political stability, US national interests, and the risk of war and terrorism. Just as homeland security encompasses many complex issues and interconnected subfields, environmental security (ES) is interdisciplinary by nature. In essence, ES is an emergent discipline borrowing from a combination of environmental studies — which decades ago integrated environmental science …

Agency Decision-Making For Climate Change: Cost-Benefit Analysis, The Precautionary Principle, And The Bounds Of Rationality, Laura Carr May 2013

Agency Decision-Making For Climate Change: Cost-Benefit Analysis, The Precautionary Principle, And The Bounds Of Rationality, Laura Carr

Pomona Senior Theses

Climate change tests the limits of human understanding of complexity and uncertainty. It challenges assumptions about our presumed power of control over this planet. This paper examines the theory of how governmental executive branch agencies make regulation decisions about climate change using the decision-making methodologies of cost-benefit analysis and the precautionary principle, and as influenced by perceptions of the bounds of human rationality and ability to deal with risk and uncertainty.

Explaining The Hydroclimatic Variability And Change In The Salmon River Basin, Venkataramana Sridhar, Xin Jin, W. Thilini Jaksa Apr 2013

Explaining The Hydroclimatic Variability And Change In The Salmon River Basin, Venkataramana Sridhar, Xin Jin, W. Thilini Jaksa

Civil Engineering Faculty Publications and Presentations

Climate change in the Pacific Northwest and in particular, the Salmon River Basin (SRB), is expected to bring about 3–5 °C rise in temperatures and an 8 % increase in precipitation. In order to assess the impacts due to these changes at the basin scale, this study employed an improved version of Variable Infiltration Capacity (VIC) model, which includes a parallel version of VIC combined with a comprehensive parameter estimation technique, Shuffled Complex Evolution (SCE) to estimate the streamflow and other water balance components. Our calibration (1955–1975) and validation (1976–1999) of the model at the outlet of the basin, White …

Orbitally Paced Shifts In The Particle Size Of Antarctic Continental Shelf Sediments In Response To Ice Dynamics During The Miocene Climatic Optimum, Sandra Passchier, Candice J. Falk, Fabio Florindo Feb 2013

Orbitally Paced Shifts In The Particle Size Of Antarctic Continental Shelf Sediments In Response To Ice Dynamics During The Miocene Climatic Optimum, Sandra Passchier, Candice J. Falk, Fabio Florindo

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The AND-2A drill hole (ANDRILL [Antarctic Geological Drilling Program] Southern McMurdo Sound Project), ∼10 km from the East Antarctica coastline, records nearly 6 m.y. of sedimentation across the Miocene climatic optimum at a high-latitude site. Sedimentological studies of bedforms and particle size distributions indicate that the paleoenvironment was strongly affected by waves and currents, consistent with deposition in a glacially influenced neritic environment. We document abrupt shifts in mud percent within glacial-interglacial cycles ca. 17.8 Ma and between ca. 16.7 and 15.7 Ma that we attribute to the hydrodynamic effects of wave stirring tied to episodes of ice growth and …

Green Politics In China: Environmental Governance And State-Society Relations, Joy Y. Zhang, Michael S. Barr Jan 2013

Green Politics In China: Environmental Governance And State-Society Relations, Joy Y. Zhang, Michael S. Barr

Books

Based on interviews with members of grassroots organisations, media and government institutions, Green Politics in China is an in-depth account of the novel ways Chinese society is responding to its environmental crisis, using examples rarely captured in Western media or academia.

The struggle for clean air, low-carbon conspiracy theories, is transforming Chinese society, producing new forms of public fund raising and the encouraging the international tactics of grassroots NGOs. In doing so, they challenge static understandings of state-society relations in China, providing a crucial insight into the way in which China is changing internally and emerging as a powerful player …

Critical Research Needs For Successful Food Systems Adaptation To Climate Change, Michelle Miller, Molly Anderson, Charles A. Francis, Chad Kruger, Carol Barford, Jacob Park, Brent H. Mccown Jan 2013

Critical Research Needs For Successful Food Systems Adaptation To Climate Change, Michelle Miller, Molly Anderson, Charles A. Francis, Chad Kruger, Carol Barford, Jacob Park, Brent H. Mccown

Department of Agronomy and Horticulture: Faculty Publications

There is a growing sense of the fragility of agricultural production in the Global North and South and of increasing risks to food security, as scientific observations confirm significant changes in the Gulf Stream, polar ice, atmospheric CO2, methane release, and other measures of climate change. This sense is heightened as each of us experiences extreme weather, such as the increasing frequency of droughts, floods, unseasonal temperatures, and erratic seasonality. The central research challenge before us is how global, national, regional, and local food systems may adapt to accelerating climate change stresses and uncertainties to ensure the availability, …

Responses To Climate Change In National Park Service Wilderness: What Is Happening In The Field?, Katherine E. Nelson Jan 2013

Responses To Climate Change In National Park Service Wilderness: What Is Happening In The Field?, Katherine E. Nelson

Graduate Student Theses, Dissertations, & Professional Papers

As scholars debate whether climate change warrants more or less active management in wilderness, this baseline study identifies what is happening on the ground. This study focuses attention on National Park Service units that administer designated wilderness. Representatives who had been identified by the superintendents from each of these units responded to an online survey (with a 94% response rate). Respondents reported on their concerns, monitoring, and management projects driven by climate change happening in their wilderness. Respondents also discussed whether and how these activities affected wilderness character. This is the first study to characterize the response to climate change …

Supporting Transitions To Resilient Irrigation Systems: Findings From Southern Kyrgyzstan, Peter Michael Igoe Jan 2013

Supporting Transitions To Resilient Irrigation Systems: Findings From Southern Kyrgyzstan, Peter Michael Igoe

Graduate Student Theses, Dissertations, & Professional Papers

This thesis presents findings from research conducted in Southern Kyrgyzstan, which followed nongovernmental organization (NGO) efforts to support climate change adaptation, and to support more “resilient” community-managed irrigation systems. Findings suggest that current NGO partnerships with Water User Associations (WUAs) frequently amount to financial and technical transactions, to preserve inherited infrastructure and resist disturbance. “Enhancing resilience” is pursued in an effort to maintain existing technical configurations of canals and water resources, despite altered socio-political and environmental conditions. Findings suggest increasing disassociation between irrigation constituents and the institutions and managers that are supposed to direct their grievances through legitimate democratic channels. …

Climate Change Effects On Vibrio Bacteria In The Winyah Bay Estuary And The Projected Spread Of Vibrio Under Future Climatic Scenarios., Reem Deeb Jan 2013

Climate Change Effects On Vibrio Bacteria In The Winyah Bay Estuary And The Projected Spread Of Vibrio Under Future Climatic Scenarios., Reem Deeb

Theses and Dissertations

While there are several studies on the distribution ofVibrio vulnificusandVibrio parahaemolyticusin estuarine waters around the world, there is little information on the distribution of both organisms in South Carolina waters. Monthly sampling of surface and bottom water from 9 sites in Winyah Bay was conducted over the period April-October 2012. Both organisms were enumerated on CHROMagarVibriomedia. TheVibriocounts obtained were mainly less than 20 Colony Forming Units (CFU)/ml which is typical for what was found elsewhere along the coast of the Carolinas. TheVibrio vulnificuscounts were the highest when salinity ranged between 5 ppt and 20 ppt.Vibrio parahaemolyticusdid not show a clear …

The Neglect Of Governance In Forest Sector Vulnerability Assessments: Structural-Functionalism And “Black Box” Problems In Climate Change Adaptation Planning, Adam Wellstead, Michael Howlett, Jeremy Rayner Jan 2013

The Neglect Of Governance In Forest Sector Vulnerability Assessments: Structural-Functionalism And “Black Box” Problems In Climate Change Adaptation Planning, Adam Wellstead, Michael Howlett, Jeremy Rayner

Department of Social Sciences Publications

Efforts to develop extensive forest-based climate change vulnerability assessments have informed proposed management and policy options intended to promote improved on-the-ground policy outcomes. These assessments are derived from a rich vulnerability literature and are helpful in modeling complex ecosystem interactions, yet their policy relevance and impact has been limited. We argue this is due to structural-functional logic underpinning these assessments in which governance is treated as a procedural “black box” and policy-making as an undifferentiated and unproblematic output of a political system responding to input changes and/or system prerequisites. Like an earlier generation of systems or cybernetic thinking about political …

A History Of Place: Using Phytolith Analysis To Discern Holocene Vegetation Change On Sanak Island, Western Gulf Of Alaska, Cricket C. Wilbur Jan 2013

A History Of Place: Using Phytolith Analysis To Discern Holocene Vegetation Change On Sanak Island, Western Gulf Of Alaska, Cricket C. Wilbur

Antioch University Dissertations & Theses

This study investigated a terrestrial climate proxy, phytoliths, as a complimentary approach to documenting the dynamics of present and past vegetation on Sanak Island, the largest island in a small island group in the eastern Aleutian archipelago, and as a new basis by which to interpret Holocene environmental variability in Alaska. A phytolith reference collection was established from 59 selected plant species of maritime tundra belonging to 27 families. The grass species and a sedge species produced abundant phytolith forms whereas the majority of dicotyledons in this study were trace producers of phytoliths. A paleoenvironmental reconstruction from fossil phytoliths recovered …

Environmental Law/Environmental Literature, Michael Burger Jan 2013

Environmental Law/Environmental Literature, Michael Burger

Sabin Center for Climate Change Law

What, is truly "environmental" about environmental law? This Article is the first attempt to answer this question by integrating Law & Literature scholarship with the study of environmental law. I argue that competing narratives of nature and culture common to the American environmental imagination play a more significant role in environmental law and litigation than previously acknowledged. These competing narratives, communicated through a known set of environmental stories and tropes, are used by attorneys to establish, frame, narrate and argue their cases, and they are absorbed, reimagined, reframed and retold by judges in their written opinions, making environmental law a …

Land Use And Climate Change: Lawyers Negotiating Above Regulation, John R. Nolon Jan 2013

Land Use And Climate Change: Lawyers Negotiating Above Regulation, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

Sea level rise requires a new paradigm for controlling the development of coastal lands that are in harm’s way, calling for adjustments in the law, legal practice, and legal education. This article discusses the historical tendency of the law to adjust to changes in society and the recent emergence of new legal institutions and strategies for mitigating and adapting to climate change, particularly sea level rise. It illustrates how the lack of certainty about the extent and pace of sea level rise collides with the total takings doctrine of the Lucas case to frustrate the application of traditional land use …

Changes Spark Interest In Sustainable Urban Places: But How Do We Identify And Support Them?, John R. Nolon Jan 2013

Changes Spark Interest In Sustainable Urban Places: But How Do We Identify And Support Them?, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

Changes in climatic and demographic trends are sparking renewed interest in cities generally and sustainable communities particularly. On the one hand, residents and workers in denser, mixed-use neighborhoods served by transit have half the carbon footprint of those in spread-out suburban areas. On the other hand, many of the smaller households that characterize the nation’s growing population prefer to live in precisely those compact, mixed-use neighborhoods. In New York, these changes align with several new state policies that encourage cities and towns to reduce carbon emissions, reduce vehicle travel, create sustainable buildings and neighborhoods, and preserve the landscapes that sequester …

Hemisphere-Scale Differences In Conifer Evolutionary Dynamics, Andrew B. Leslie, Jeremy M. Beaulieu, Hardeep S. Rai, Peter R. Crane, Michael J. Donoghue, Sarah Mathews Oct 2012

Hemisphere-Scale Differences In Conifer Evolutionary Dynamics, Andrew B. Leslie, Jeremy M. Beaulieu, Hardeep S. Rai, Peter R. Crane, Michael J. Donoghue, Sarah Mathews

Faculty Publications

Fundamental differences in the distribution of oceans and landmasses in the Northern and Southern Hemispheres potentially impact patterns of biological diversity in the two areas. The evolutionary history of conifers provides an opportunity to explore these dynamics, because the majority of extant conifer species belong to lineages that have been broadly confined to the Northern or Southern Hemisphere during the Cenozoic. Incorporating genetic information with a critical review of fossil evidence, we developed an age-calibrated phylogeny sampling ∼80% of living conifer species. Most extant conifer species diverged recently during the Neogene within clades that generally were established during the later …

Estimation Of The Total Co2 Content Of The Atmosphere From Satellite Observations, G. A. Alexandrov, Tsuneo Matsunaga Jul 2012

Estimation Of The Total Co2 Content Of The Atmosphere From Satellite Observations, G. A. Alexandrov, Tsuneo Matsunaga

International Congress on Environmental Modelling and Software

Stabilization of the total CO2 content of the atmosphere is the target of the climate strategies that are proposed for climate change mitigation. The accuracy of our knowledge about the total CO2 content of the atmosphere, its growth and seasonal variations depends on the size of geographic coverage of the CO2 monitoring network. A good opportunity to enhance the monitoring network arose recently due to the launch of the Greenhouse gases Observing Satellite (GOSAT). The data coming from GOSAT provide unprecedented geographic coverage of column averaged CO2 concentrations and, therefore, may have the potential to improve the estimates of the …

Permafrost Settlement Caused By Climate Warming In Alaska And The Estimation Of Its Damage Costs For Public Infrastructure, Eunkyoung Hong Apr 2012

Permafrost Settlement Caused By Climate Warming In Alaska And The Estimation Of Its Damage Costs For Public Infrastructure, Eunkyoung Hong

Engineering

Climate models and studies indicate that the changes in the northern latitudes will be serious and accelerated. Climate warming may impact structures in the northern latitudes through permafrost settlement affecting the performance of infrastructure and increasing costs for maintenance. The material presented is organized in three main chapters. Chapter 1 describes the motivation for the research. Chapter 2 addresses the permafrost settlement hazard in Alaska. I developed the Permafrost Settlement Hazard Index, which considered anticipated climate warming and ecological characteristics which regulate permafrost settlement. I found that the discontinuous permafrost region is at more risk due to permafrost settlement than …

Impacts Of Climate Change On Hydrology And Water Resources In The Boise And Spokane River Basins, Xin Jin, Venkataramana Sridhar Apr 2012

Impacts Of Climate Change On Hydrology And Water Resources In The Boise And Spokane River Basins, Xin Jin, Venkataramana Sridhar

Civil Engineering Faculty Publications and Presentations

In the Pacific Northwest, warming climate has resulted in a lengthened growing season, declining snowpack, and earlier timing of spring runoff. This study characterizes the impact of climate change in two basins in Idaho, the Spokane River and the Boise River basins. We simulated the basin-scale hydrology by coupling the downscaled precipitation and temperature outputs from a suite of global climate models and the Soil and Water Assessment Tool (SWAT), between 2010 and 2060 and assess the impacts of climate change on water resources in the region. For the Boise River basin, changes in precipitation ranged from −3.8 to 36%. …

Standing For Private Parties In Global Warming Cases: Traceable Standing Causation Does Not Require Proximate Causation, Bradford Mank Jan 2012

Standing For Private Parties In Global Warming Cases: Traceable Standing Causation Does Not Require Proximate Causation, Bradford Mank

Faculty Articles and Other Publications

This Article argues courts should apply a relatively liberal approach in deciding standing issues for private plaintiffs pursuing climate change suits even if courts ultimately conclude that it is inappropriate to grant relief on the merits to those same plaintiffs because the Supreme Court has clearly declared that standing is a preliminary question that should be treated separately from decisions on the merits and standing causation requires less proof than proximate causation on the merits. The Supreme Court in its 2007 decision in Massachusetts v. EPA held that a state had standing under Article III of the U.S. Constitution to …

Regulation Or Litigation: Using The American Legal System To Address Climate Change, Stacy Lynne Boman Jan 2012

Regulation Or Litigation: Using The American Legal System To Address Climate Change, Stacy Lynne Boman

Graduate Student Theses, Dissertations, & Professional Papers

While a growing scientific consensus recognizes that anthropogenic greenhouse gas emissions are contributing to the global phenomenon known as climate change, little progress has been made to pass comprehensive legislation addressing climate change. Many concerned with the effects of climate change have turned to the American court system as a means of addressing climate change or reducing greenhouse gases. Similar to the early litigation history of many environmental cases, climate change litigation has thus far been unsuccessful in holding major greenhouse gas emitters liable for the impacts of climate change. Plaintiffs have not given up, however. Many climate change cases …

From Pond To Pump: Microalgae As A Feedstock For Biodiesel, Anna H. Leavitt Jan 2012

From Pond To Pump: Microalgae As A Feedstock For Biodiesel, Anna H. Leavitt

Honors Theses

The global reliance on fossil fuels is an unsustainable practice that has led to the depletion of finite resources and the accumulation of greenhouse gases in the atmosphere, leading to global climate change (Demirbas 2010). Transportation accounts for about a third of carbon dioxide (CO2) emissions in the United States. Demand for oil continues to increase and resources are becoming more uncertain. Increased production of renewable fuels such as biofuels can help ease the dependence on fossil fuels. Although interest and production in biofuels has been increasing in the past decade, current feedstocks do not meet efficiency needs and some …
