A Framework Of Ordered Climate Effects On Water Resources: A Comprehensive Bibliography, Elizabeth L. Chalecki, Peter H. Gleick

Political Science Faculty Publications

An examination of the metadata for almost 900 bibliographic references on the effects of climate change and variability on U.S. water resources reveals strengths and weaknesses in our current knowledge. Considerable progress has been made in the modeling of climate change effects on first-order systems such as regional hydrology, but significant work remains to be done in understanding subsequent effects on the second-, third-, and fourth-order economic and social systems (e.g., agriculture, trade balance, and national economic development) that water affects. In order to remedy a recently-revealed lack of understanding about climate change on the part of the public, climate …

Bayesian Change-Point Analyses In Ecology, Brian Beckage, Lawrence Joseph, Patrick Belisle, David B. Wolfson, William J. Platt

Faculty Publications

• Ecological and biological processes can change from one state to another once a threshold has been crossed in space or time. Threshold responses to incremental changes in underlying variables can characterize diverse processes from climate change to the desertification of arid lands from overgrazing. • Simultaneously estimating the location of thresholds and associated ecological parameters can be difficult: ecological data are often 'noisy', which can make the identification of the locations of ecological thresholds challenging. • We illustrate this problem using two ecological examples and apply a class of statistical models well-suited to addressing this problem. We first consider …

From Isotopes To Tk Interviews: Towards Interdisciplinary Research In Fort Resolution And The Slave River Delta, Northwest Territories, Brent B. Wolfe, Derek Armitage, Bronwyn E. Brock, Michael A. Sokal, Kenneth P. Clogg-Wright, Cherie L. Mongeon, Margaret E. Adam, Roland I. Hall, Thomas W.D. Edwards

Geography and Environmental Studies Faculty Publications

Evolving research in Fort Resolution and the Slave River Delta, Northwest Territories, aims to improve understanding of how the natural ecosystem functions and responds to various environmental stressors, as well as to enhance the stewardship of natural resources and the capacity of local residents to respond to change. We seek to integrate approaches that span the natural and social sciences and traditional knowledge understandings of change, employing a research design developed in response to the concerns of a northern community. In doing so, we have strived for a research process that is collaborative, interdisciplinary, policy-oriented, and reflective of northern priorities. …

Climate Change, Zoning And Transportation Planning: Urbanization As A Response To Carbon Loading, John R. Nolon, Jessica A. Bacher

Elisabeth Haub School of Law Faculty Publications

This article explores the relationship among zoning, transportation planning, and climate change. It discusses the relationship between land use densities and transportation choices, reviews the trend toward transit oriented development in higher density communities and transportation efficient development in lower density areas, presents several case studies where land use and transportation planning are beginning to intersect, and ends with a strategic approach for communities to consider.

The Big One, Edward A. Parson

Reviews

Richard Posner's Catastrophe: Risk and Response (Oxford University Press, 2004) examines four risks whose worst cases could end advanced human civilization or worse: asteroid impacts, a catastrophic chain reaction initiated in high-energy particle accelerators, global climate change, and bioterrorism. He argues that these all warrant more thought and response than they are receiving, and that they can usefully be assessed using a simple analytic framework based on cost-benefit analysis. This essay reviews knowledge of these risks and critically examines Posner's claims for a consistent analytic approach. While the conclusions that each risk merits more thought and effort appear persuasive, these …

Response Of Eelgrass Zostera Marina To Co2 Enrichment: Possible Impacts Of Climate Change And Potential For Remediation Of Coastal Habitats, Sherry L. Palacios, Richard C. Zimmerman

OES Faculty Publications

Projected increases in dissolved aqueous concentrations of carbon dioxide [CO_2(aq)] may have significant impacts on photosynthesis Of CO₂-limited organisms such as seagrasses. Short-term CO_2(aq) enrichment increases photosynthetic rates and reduces light requirements for growth and survival of individual eelgrass Zostera marina L. shoots growing in the laboratory under artificial light regimes for at least 45 d. This study examined the effects of long-term CO_2(aq) enrichment on the performance of eelgrass growing under natural light-replete (33% surface irradiance) and light-limited (5% surface irradiance) conditions for a period of 1 yr. Eelgrass shoots were grown at …

Assessing Forest Responses To Climate Change And Resolving Productivity Measurements Across Spatial Scales, Céline Boisvenue

Graduate Student Theses, Dissertations, & Professional Papers

Informed decisions regarding forest and carbon resources require knowledge of the impacts of environmental changes on forest productivity. We also need to reconcile the diverging productivity estimates that are presently available. This dissertation assembles two publications addressing the impacts of climate change on forest productivity and one exploring the relationship between three estimates of forest productivity. In the first chapter, I evaluated whether forests have responded to recent changes in climatic conditions. Through combining published evidence I show that forests have responded to changes in the patterns of light, water, and temperatures over the last half of the 20th century. …

Climate Change, The United States, And The Impacts Of Arctic Melting: A Case Study In The Need For Enforceable International Environmental Human Rights, Randall S. Abate

Journal Publications

Climate change is currently the most significant and daunting international environmental problem, with disproportionate and devastating impacts on indigenous groups. The plight of the Inuit is illustrative of a larger need to recognize and enforce international environmental human rights violations. Part I of this Article examines the evolution of various approaches to environmental human rights theories in (1) United States law, (2) international human rights law instruments, and (3) the laws of other nations. Part II considers the scientific evidence and legal theory underlying the Inuit petition before the Inter-American Commission on Human Rights and explores how this scenario underscores …

Predicting Spotted Knapweed (Centaurea Maculosa) Range Expansion Near Missoula Montana Using Localized Climate And Elevation Data, William Frank Preston Cumming

Graduate Student Theses, Dissertations, & Professional Papers

Since the 1920s spotted knapweed (Centaurea maculosa) has adapted to a variety of habitats, including pastureland, rangeland, hay land, open forests, road sides, and ditches. In 2003 this plant species dominated more than five million acres in Montana, half of the total infestation of noxious weeds in the state. This project demonstrates the utility of using downscaled Parameter-elevation Regressions on Independent Slopes Model (PRISM) data for predicting vegetation movement within a 2°×2° geographical area surrounding Missoula County, Montana. This localized climate change data was correlated against current knapweed range using validation data from the Volunteer for Wilderness Program at the …

The Response Of A General Circulation Climate Model Tohigh Latitude Freshwater Forcing In The Atlantic Basinwith Respect Totropi, Victor Paulis

Electronic Theses and Dissertations

The current cycle of climate change along with increases in hurricane activity, changing precipitation patterns, glacial melt, and other extremes of weather has led to interest and research into the global correlation or teleconnection between these events. Examination of historical climate records, proxies and observations is leading to formulation of hypotheses of climate dynamics with modeling and simulation being used to test these hypotheses as well as making projections. Ocean currents are believed to be an important factor in climate change with thermohaline circulation (THC) fluctuations being implicated in past cycles of abrupt change. Freshwater water discharge into high-latitude oceans …

A 1400-Year Multi-Proxy Record Of Climate Variability From The Northern Gulf Of Mexico, Julie N. Richey

USF Tampa Graduate Theses and Dissertations

A continuous, decadal-scale resolution multi-proxy record of climate variability over the past 1400 years in the northern Gulf of Mexico (GOM) was constructed from a box core recovered in the Pigmy Basin. Proxies include paired analyses of Mg/Ca and oxygen isotopes in the white variety of the planktic foraminifer Globigerinoides ruber and relative abundance variations of G. sacculifer in the foraminifer assemblages. Two multi-decadal intervals of sustained high Mg/Ca values indicate GOM sea-surface temperatures (SSTs) were as warm or warmer than near-modern conditions between 1000 and 1400 yrs BP. Foraminiferal Mg/Ca values during the coolest interval of the Little Ice …

Interaction Of Ice Storms And Management Practices On Current Carbon Sequestration In Forests With Potential Mitigation Under Future Co2 Atmosphere, Heather R. Mccarthy, Ram Oren, Hyun-Seok Kim, Kurt H. Johnsen, Chris Maier, Seth G. Pritchard, Micheal Davis

Faculty Publications

[1] Ice storms are disturbance events with potential impacts on carbon sequestration. Common forest management practices, such as fertilization and thinning, can change wood and stand properties and thus may change vulnerability to ice storm damage. At the same time, increasing atmospheric CO₂ levels may also influence ice storm vulnerability. Here we show that a nonintensively managed pine plantation experienced a ∼250 g C m⁻² reduction in living biomass during a single storm, equivalent to ∼30% of the annual net ecosystem carbon exchange of this ecosystem. Drawing on weather and damage survey data from the entire storm cell, …

Climate Variability Has A Stabilizing Effect On The Coexistence Of Prairie Grasses, Peter B. Adler, Janneke Hille Ris Lambers, Phaedon C. Kyriakidis, Qingfeng Guan, Jonathan M. Levine

School of Natural Resources: Faculty Publications

How expected increases in climate variability will affect species diversity depends on the role of such variability in regulating the coexistence of competing species. Despite theory linking temporal environmental fluctuations with the maintenance of diversity, the importance of climate variability for stabilizing coexistence remains unknown because of a lack of appropriate long-term observations. Here, we analyze three decades of demographic data from a Kansas prairie to demonstrate that interannual climate variability promotes the coexistence of three common grass species. Specifically, we show that (i) the dynamics of the three species satisfy all requirements of ‘‘storage effect’’ theory based on recruitment …
