Invasive Species And Climate Change, Invasive Species Advisory Committee
National Invasive Species Council
ISSUE
Climate change interacts with and can often amplify the negative impacts of invasive species. These interactions are not fully appreciated or understood. They can result in threats to critical ecosystem functions on which our food system and other essential provisions and services depend as well as increase threats to human health. The Invasive Species Advisory Committee to the National Invasive Species Council recognizes the Administration’s commitment to dealing proactively with global climate change. However, unless we recognize and act on the impact of climate change and its interaction with ecosystems and invasive species, we will fall further behind in …
Economic Writing On The Pressing Problems Of The Day: The Roles Of Moral Intuition And Methodological Confusion, Julie A. Nelson
Economic Writing On The Pressing Problems Of The Day: The Roles Of Moral Intuition And Methodological Confusion, Julie A. Nelson
Economics Faculty Publication Series
Economists are often called on to help address pressing problems of the day, yet many economists are uncomfortable about disclosing the values that they bring to this work. This essay explores how an inadequate understanding of the role of methodology, as related to ethics and human emotions of concern, underlies this reluctance and compromises the quality of economic advice. The tension between caring about the problems, on the one hand, and writing within the existing culture of the discipline, on the other, are illustrated with examples from U.S. policymaking, behavioral economics, and the economics of climate change and global poverty. …

Twenty-Eight Years Of The Us-Lter Program: Experience, Results, And Research Questions, James R. Gosz, Robert B. Waide, John J. Magnuson
Long Term Ecological Research Network
The U.S. Long Term Ecological Research program (hereafter US-LTER) concentrates on ecological processes that play out at the time scales spanning decades to centuries. This focuses US-LTER research between the most common time scales for ecological studies (1-3 years; Tilman 1989; Figure 1) and the much longer temporal fact of disciplines such as paleoecology. The importance of the decade-to-century time scale is particularly evident in light of the rapid changes in ecological forcing functions that are occurring at a broad range of spatial scales (Millennium Ecosystem Assessment 2005, Intergovernmental Panel on Climate Change 2007). Long-term data sets from programs such …

Earth Sciences
Land-use change to meet 21st-century demands for food, fuel, and fiber will depend on many interactive factors, including global policies limiting anthropogenic climate change and realized improvements in agricultural productivity. Climate-change mitigation policies will alter the decision-making environment for land management, and changes in agricultural productivity will influence cultivated land expansion. We explore to what extent future increases in agricultural productivity might offset conversion of tropical forest lands to crop lands under a climate mitigation policy and a contrasting no-policy scenario in a global integrated assessment model. The Global Change Assessment Model is applied here to simulate a mitigation policy …

Geography Faculty Publications
Geographers have a long tradition of classifying cities using a number of criteria. Population size, industrial production, capital city functions, airline connections, sites of sporting events and major headquarters and banks are among them. While these studies are useful in looking at cities in an economy and population at a given point of time, they are less useful in assessing rapidly occurring changes within a regional or global system. Our research represents a new approach to classify cities and urban systems; we use the volume and networks/linkages or flows associated with electronic Information or “Knowledge worlds.” We argue that in …
Arctic Ecosystem Responses To Changes In Water Availability And Warming: Short And Long-Term Responses, Paulo C. Olivas
Arctic Ecosystem Responses To Changes In Water Availability And Warming: Short And Long-Term Responses, Paulo C. Olivas
FIU Electronic Theses and Dissertations
Arctic soils store close to 14% of the global soil carbon. Most of arctic carbon is stored below ground in the permafrost. With climate warming the decomposition of the soil carbon could represent a significant positive feedback to global greenhouse warming. Recent evidence has shown that the temperature of the Arctic is already increasing, and this change is associated mostly with anthropogenic activities. Warmer soils will contribute to permafrost degradation and accelerate organic matter decay and thus increase the flux of carbon dioxide and methane into the atmosphere. Temperature and water availability are also important drivers of ecosystem performance, but …

To examine the role of climatic extremes in structuring reef fish communities in the Arabian region, reef fish communities were visually surveyed at four sites within the southern Persian Gulf (also known as the Arabian Gulf and The Gulf), where sea-surface temperatures are extreme (range: 12–35° C annually), and these were compared with communities at four latitudinally similar sites in the biogeographically connected Gulf of Oman, where conditions are more moderate (range: 22–31° C annually). Although sites were relatively similar in the cover and composition of coral communities, substantial differences in the structure and composition of associated fish assemblages were …

The Mysteries Of Trend, Peter C.B. Phillips
The Mysteries Of Trend, Peter C.B. Phillips
Cowles Foundation Discussion Papers
Trends are ubiquitous in economic discourse, play a role in much economic theory, and have been intensively studied in econometrics over the last three decades. Yet the empirical economist, forecaster, and policy maker have little guidance from theory about the source and nature of trend behavior, even less guidance about practical formulations, and are heavily reliant on a limited class of stochastic trend, deterministic drift, and structural break models to use in applications. A vast econometric literature has emerged but the nature of trend remains elusive. In spite of being the dominant characteristic in much economic data, having a role …
International Greenhouse Gas Offsets Under The Clean Air Act, Nathan D. Richardson
International Greenhouse Gas Offsets Under The Clean Air Act, Nathan D. Richardson
Faculty Publications
Offsets, and in particular international offsets, have been advanced as an important tool in climate policy, capable of significantly reducing the costs of emissions reductions. As attention turns to the existing CAA as a potential vehicle for general reduction of GHG emissions, an important question is whether regulation under the statute is compatible with international offsets. Certain regulatory programs under the CAA are likely candidates for GHG regulation, but many of them are legally incompatible with international offsets. Those programs that might permit use of international offsets have other problems that make them unpopular choices for GHG regulation. To the …

Climate change poses profound, direct, and well-documented threats to biodiversity. A significant fraction of Earth's species is at risk of extinction due to changing precipitation and temperature regimes, rising and acidifying oceans, and other factors. There is also growing awareness of the diversity and magnitude of responses, both proactive and reactive, that people will undertake as lives and livelihoods are affected by climate change. Yet to date few studies have examined the relationship between these two powerful forces. The natural systems upon which people depend, already under direct assault from climate change, are further threatened by how we respond to …

Physical Properties Of The Us Itase Firn And Ice Cores From South Pole To Taylor Dome, Debra A. Meese, Ian Baker
University of Maine Office of Research Administration: Grant Reports
This award supports a project for physical properties research on snow pits and firn/ice cores with specific objectives that include stratigraphic analysis including determination of accumulation rates, annual layers, depth hoar, ice and wind crusts and rates of grain growth with depth. Studies of firn densification rates and how these parameters relate to the meteorology and climatology over the last 200 years of snow accumulation in Antarctica will also be investigated. The project will also determine the seasonality of accumulation by co-registration of stratigraphy and chemistry and determination of chemical species at the grain boundaries, how these may change with …

Simulations Show Decreasing Carbon Stocks And Potential For Carbon Emissions In Rocky Mountain Forests Over The Next Century, Céline Boisvenue, Steven W. Running
Numerical Terradynamic Simulation Group Publications
Climate change has altered the environment in which forests grow, and climate change models predict more severe alterations to come. Forests have already responded to these changes, and the future temperature and precipitation scenarios are of foremost concern, especially in the mountainous western United States, where forests occur in the dry environments that interface with grasslands. The objective of this study was to understand the trade-offs between temperature and water controls on these forested sites in the context of available climate projections. Three temperature and precipitation scenarios from IPCC AR4 AOGCMs ranging in precipitation levels were input to the process …

Civil, Environmental and Sustainable Engineering
Three statistical downscaling methods were applied to NCEP/NCAR reanalysis (used as a surrogate for the best possible general circulation model), and the downscaled meteorology was used to drive a hydrologic model over California. The historic record was divided into an “observed” period of 1950–1976 to provide the basis for downscaling, and a “projected” period of 1977–1999 for assessing skill. The downscaling methods included a biascorrection/ spatial downscaling method (BCSD), which relies solely on monthly large scale meteorology and resamples the historical record to obtain daily sequences, a constructed analogues approach (CA), which uses daily large-scale anomalies, and a hybrid method …

The Effect Of Risk, Ambiguity And Coordination On Farmers’ Adaptation To Climate Change: A Framed Field Experiment, Francisco Alpizar, Fredrik Carlsson, Maria Naranjo
Fondazione Eni Enrico Mattei Working Papers
The risk of losses of income and productive means due to adverse weather associated to climate change can significantly differ between farmers sharing a productive landscape. It is important to learn more about how farmers react to different levels of risk, under measurable and unmeasurable uncertainty. Moreover, the costs associated to investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore these issues using a framed field experiment that captures realistically the main characteristics of production, and the likely weather related losses of premium coffee farmers in Tarrazu, Costa Rica. Given that the region …

National Invasive Species Council
BACKGROUND
Invasive species are second only to habitat destruction as the greatest cause of species endangerment and global biodiversity loss. Invasive species can cause severe and permanent damage to the ecosystems they invade. Consequences of invasion include competition with or predation upon native species, hybridization, carrying or supporting harmful pathogens and parasites that may affect wildlife and human health, disturbing ecosystem function through alteration of food webs and nutrient recycling rates, acting as ecosystem engineers and altering habitat structure, and degradation of the aesthetic quality of our natural resources. In many cases we may not fully know the native animals …

Recent Advances In The Climate Change Biology Literature: Describing The Whole Elephant, A. Townsend Peterson, Shaily Menon, Xingong Li
Peer Reviewed Publications
Climate change biology is seeing a wave of new contributions, which are reviewed herein. Contributions treat shifts in phenology and distribution, and both document past and forecast future effects. However, many of the current wave of contributions are observational and correlational, and few are experimental in nature, and too often a conceptual framework in which to contextualize the results is lacking. An additional gap is the lack of effective cross-linking among areas of research, for example, connection of sea-level rise and climate change implications for distributions of species, or evolutionary adaptation studies with distributional shift studies. Although numerous important contributions …

A study was conducted in Missoula, Montana to compare local pollen counts from 1978 with those measured nearly 30 years later in 2006 using two different measurement techniques (Durham gravimetric sampler and a Burkard volumetric sampler). Trends in peak pollen times measured during the spring, summer and autumn, respectively, were compared between the two years by Pearson’s correlation and frequency of occurrence of plant genus. Meteorological conditions were also examined during each of the two study periods.
In comparing the two years, there was a statistically significant linear association between the different counts for the months of April through August, …
Essays On Equity-Efficiency Trade Offs In Energy And Climate Policies, Juan P. Sesmero
Essays On Equity-Efficiency Trade Offs In Energy And Climate Policies, Juan P. Sesmero
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Economic efficiency and societal equity are two important goals of public policy. Energy and climate policies have the potential to affect both. Efficiency is increased by substituting low-carbon energy for fossil energy (mitigating an externality) while equity is served if such substitution enhances consumption opportunities of unfavored groups (low income households or future generations). However policies that are effective in reducing pollution may not be so effective in redistributing consumption and vice-versa. This dissertation explores potential trade-offs between equity and efficiency arising in energy and climate policies.
Chapter 1 yields two important results. First, while effective in reducing pollution, energy …

Short-Beaked Common Dolphin (Delphinus Delphis) Occurrence In The Moray Firth, North-East Scotland, Kevin P. Robinson, Sonja Eisfeld, Marina Costa, Mark P. Simmonds
Ecology Collection
The short-beaked common dolphin (Delphinus delphis) is regarded as notably rare or absent from the northern North Sea, but recent evidence suggests a rising frequency of the species in these waters with increasing regional sea temperatures. The following paper documents the presence of D. delphis in the Moray Firth in north-east Scotland and provides the first evidence for the sustained occurrence of these delphinids in this region during the warmer summer months at least. Sightings were collated during systematic surveys of the outer Moray Firth between 2001 and 2009 by independent research teams from the CRRU and WDCS. A total …

Global Warming Advocacy Science: A Cross Examination, Jason S. Johnston
All Faculty Scholarship
Legal scholarship has come to accept as true the various pronouncements of the Intergovernmental Panel on Climate Change (IPCC) and other scientists who have been active in the movement for greenhouse gas (ghg) emission reductions to combat global warming. The only criticism that legal scholars have had of the story told by this group of activist scientists – what may be called the climate establishment – is that it is too conservative in not paying enough attention to possible catastrophic harm from potentially very high temperature increases. This paper departs from such faith in the climate establishment by comparing the …

Long‐term data from the Hubbard Brook Experimental Forest in New Hampshire show that air temperature has increased by about 1 °C over the last half century. The warmer climate has caused significant declines in snow depth, snow water equivalent and snow cover duration. Paradoxically, it has been suggested that warmer air temperatures may result in colder soils and more soil frost, as warming leads to a reduction in snow cover insulating soils during winter. Hubbard Brook has one of the longest records of direct field measurements of soil frost in the United States. Historical records show no long‐term trends in …

State-Oil Run Company Pemex Attempts To Reduce Carbon Footprint, Sourcemex Writers
NotiEn: An Analytical Digest About Energy Issues in Latin America
The Mexican government is working hard to reduce the carbon footprint of the state-run oil company PEMEX, but the results thus far have been uneven at best. PEMEX has placed a high priority on actions that will help protect the environment, such as steps to greatly reduce emissions at some processing plants and introducing ethanol into the mix for gasoline in the three largest cities. But critics say these steps are very small when compared with the overall damage that the company has continued causing to the air, soil, and water in Mexico in recent years. Even some solutions, such …

The title photo of a glacier overlying a karst aquifer in the Swiss Alps was taken in September 2009. The red number on the polished limestone surface in the foreground indicates the position of the glacier in 2003. Since then, the glacier has lost ca. 182 m in length and 9 m in thickness. If retreat continues at this rate, most of this small glacier will have vanished by approximately 2035 (while most large glaciers will probably shrink but still exist). The spring draining the aquifer supplied by this glacier is used for drinking water supply and irrigation. How will …
