Recent Unprecedented Tree-Ring Growth In Bristlecone Pine At The Highest Elevations And Possible Causes, Matthew W. Salzer, Malcolm K. Hughes, Andrew G. Bunn, Kurt F. Kipfmueller Dec 2009

Recent Unprecedented Tree-Ring Growth In Bristlecone Pine At The Highest Elevations And Possible Causes, Matthew W. Salzer, Malcolm K. Hughes, Andrew G. Bunn, Kurt F. Kipfmueller

Andrew G. Bunn

Great Basin bristlecone pine (Pinus longaeva) at 3 sites in western North America near the upper elevation limit of tree growth showed ring growth in the second half of the 20th century that was greater than during any other 50-year period in the last 3,700 years. The accelerated growth is suggestive of an environmental change unprecedented in millennia. The high growth is not overestimated because of standardization techniques, and it is unlikely that it is a result of a change in tree growth form or that it is predominantly caused by CO2 fertilization. The growth surge has occurred only in …


A Fateful Year For Climate Change, William J. Antholis Nov 2009

A Fateful Year For Climate Change, William J. Antholis

Brookings Scholar Lecture Series

Since 1979, 20% of the polar ice cap has melted away. While the public is aware of climate change, the urgency to action is not there. Climate change is also an issue of national security, but enforcement of the the Kyoto and Copenhagen treaties is hampered.

Carbon Capture And Storage: Combining Economic Analysis With Expert Elicitations To Inform Climate Policy, Erin D. Baker, Haewon Chon, Jeffrey M. Keisler Oct 2009

Carbon Capture And Storage: Combining Economic Analysis With Expert Elicitations To Inform Climate Policy, Erin D. Baker, Haewon Chon, Jeffrey M. Keisler

Management Science and Information Systems Faculty Publication Series

The relationship between R&D investments and technical change is inherently uncertain. In this paper we combine economics and decision analysis to incorporate the uncertainty of technical change into climate change policy analysis. We present the results of an expert elicitation on the prospects for technical change in carbon capture and storage. We find a significant amount of disagreement between experts, even over the most mature technology; and this disagreement is most pronounced in regards to cost estimates. We then use the results of the expert elicitations as inputs to the MiniCAM integrated assessment model, to derive probabilistic information about the …

Differential Response Of Amp Activated Protein Kinase (Ampk) And Hsp70 To Temperature Stress In The Gastropod, Nucella Lapillus, Emily Zimmermann Apr 2009

Differential Response Of Amp Activated Protein Kinase (Ampk) And Hsp70 To Temperature Stress In The Gastropod, Nucella Lapillus, Emily Zimmermann

All Theses And Dissertations

Populations of the gastropod Nucella lapillus are polymorphic for shell color, with light-colored shells predominating on warmer, wave-protected shores and dark-colored shells limited primarily to cooler, wave-exposed shores. During thermal stress, darker shells attain higher body temperatures than lighter shells. These results suggest that heat stress may determine field distribution patterns. However, there is currently little evidence of physiological consequences of thermal stress in these organisms. Following the guiding hypothesis that heat stress leads to cellular energy depletion, we explored whether the central energy regulator AMP-activated Protein Kinase (AMPK) is activated by heat stress. We compared this response in both …


The Rock And Ice Problem In National Parks: An Opportunity For Monitoring Climate Change Impacts, Andrew Godard Bunn Apr 2009

The Rock And Ice Problem In National Parks: An Opportunity For Monitoring Climate Change Impacts, Andrew Godard Bunn

Environmental Sciences Faculty and Staff Publications

The fundamental physics of an enhanced greenhouse effect due to fossil fuel combustion is well understood, and Earth is warming (IPCC 2007). Considerable uncertainty exists regarding the impacts of climate change, but high latitudes and high elevations are thought to be leading indicators of future trends. The suite of high-elevation lands protected by the National Park Service is ideal in terms of documenting and monitoring the physical, floral, and faunal impacts of climate change. Indeed, the network of alpine lands managed by the Park Service in the mountainous western United States spans maritime-to-arid ecosystems over a dozen degrees of latitude …


Sustainable Portland: Implementation Series 2, New England Environmental Finance Center Apr 2009

Sustainable Portland: Implementation Series 2, New England Environmental Finance Center

Climate Change

The Portland Municipal Climate Change Working Group prepared a report in March 2008 that outlined several recommendations as a commitment by the City to address greenhouse gas emissions (GHG) produced during daily municipal operations. The Municipal Climate Action Plan was written in partnership with Clean Air – Cool Planet and Portland officials, and acknowledges under Recommendation #2 that an employee energy efficiency program would provide significant positive impact on the City’s reduction of greenhouse gas emissions. Best practices from three cities show that focus on the greening of City Hall is critical in developing a program that promotes partnerships, community …


An Hsus Report: The Implications Of Farm Animal-Based Bioenergy Production, The Humane Society Of The United States Jan 2009

An Hsus Report: The Implications Of Farm Animal-Based Bioenergy Production, The Humane Society Of The United States

Impact of Animal Agriculture

As the current and potential impacts of climate change become more evident and increasingly urgent, entities such as governments, corporations, and non-governmental organizations (NGOs) are seeking out non-fossil fuelbased sources of energy to mitigate those effects. In addition, many governments are investigating ways to promote their own domestic energy sources as a result of rising oil prices. Bioenergy—made from recently living organic matter, such as plants, agricultural waste and crop residue, meat processing wastes, or farmed animals’ fats and manure—has quickly become one of the fastest growing, and controversial, alternative energy sources. Globally, production of biofuels, generally used for transport, …


Review Essay: Disagreeing About The Climate, Donald Nordberg Jan 2009

Review Essay: Disagreeing About The Climate, Donald Nordberg

Donald Nordberg

This paper is an early draft of a review essay that subsequently appeared in the journal Business and Society in 2010. The science concerning climate change is clear, both sides of the argument agree. What they don't agree about is what that clarity means. Each side considers the matter settled, and their points of view unsettle each attempt to make public policy. Mike Hulme, director of the Tyndall Centre for Climate Change Research at the University of East Anglia, thinks the reasons for the persistent differences lies in the complex ways we see and use climate change as a totem …


Problems Of Equity And Efficiency In The Design Of International Greenhouse Gas Cap-And-Trade Schemes, Jason S. Johnston Jan 2009

Problems Of Equity And Efficiency In The Design Of International Greenhouse Gas Cap-And-Trade Schemes, Jason S. Johnston

All Faculty Scholarship

This article argues that international greenhouse gas (GHG) cap-and-trade schemes suffer from inherent problems of enforceability and verifiability that both cause significant inefficiencies and create inevitable tradeoffs between equity and efficiency. A standard result in the economic analysis of international GHG cap and trade schemes is that an allocation of initial permits that favors poor, developing countries (making such countries net sellers in equilibrium) may be necessary not only to further redistributive goals but also the efficiency of the GHG cap and trade scheme. This coincidence of equity and efficiency is, however, unlikely to be realized under more realistic assumptions …

Climate Change: Helping Nature Survive The Human Response, Will R. Turner, Bethany A. Bradley, Lyndon D. Estes, David G. Hole, Michael Oppenheimer, David S. Wilcove

Environmental Conservation Faculty Publication Series

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 …


Seeing Shifts: Ecologists' Lived Experiences Of Climate Change In Mountains Of The American West, Kimberly Ford Langmaid Jan 2009

Seeing Shifts: Ecologists' Lived Experiences Of Climate Change In Mountains Of The American West, Kimberly Ford Langmaid

Antioch University Full-Text Dissertations & Theses

This study explores the lived experiences of field ecologists who research the effects of global climate change on mountain species and ecosystems in the American West. The purpose is to generate narrative descriptions of ecologists’ experiences in order to communicate about both the scientific ecology and human ecology of climate change. Twenty prominent field ecologists participated in this study. Interviews with ecologists were transcribed and analyzed using a hermeneutic phenomenological methodology. Eight experiential themes emerged through the process of data analysis, and these themes provide the structure for presenting narratives of ecologists’ experiences. The eight themes are: thinking ecologically, the …
