Study Group On Climate Change Recommendations Progress Report, Dano Weisbord

Year on Climate Change: Other Materials

Climate change is an urgent, complex problem. Human activities are pushing the climate beyond the range of conditions experienced over the last few million years and toward abrupt, unpredictable, highly damaging and potentially irreversible impacts. Effective responses will require ambitious, multifaceted plans of action.

Proxy Carbon Life Cycle Cost Calculator Tool V2.0, Alexander R. Barron, Breanna J. Parker, Susan Stratton Sayre

Year on Climate Change: Other Materials

The Smith College Proxy Carbon Life Cycle Cost Calculator is a tool designed to include climate impacts in the evaluation of present and future costs of projects on campus. At the request of the Study Group on Climate Change, this Excel tool was developed as part of the implementation of a proxy carbon price at Smith College.

Spreadsheet calculator to support proxy carbon pricing based on life cycle cost analyses. The tool targets small institutions.

Policy Insights From Comparing Carbon Pricing Modeling Scenarios, Alexander R. Barron, Marc A.C. Hafstead, Adele C. Morris

Environmental Science and Policy: Faculty Publications

Carbon pricing is an important policy tool for reducing greenhouse gas pollution. The Stanford Energy Modeling Forum exercise 32 convened eleven modeling teams to project emissions, energy, and economic outcomes of an illustrative range of economy-wide carbon price policies. The study compared a coordinated reference scenario involving no new policies with policy scenarios that impose a price on all fossil fuel-related carbon dioxide (CO2) emissions in the U.S. The CO2 price scenarios begin in 2020 at $25/ton or $50/ton and rise each year over inflation at one percent or five percent. The scenarios also vary by the use of the …

Relationships Between Institutional Success And Length Of Tenure In A Kenyan Irrigation Scheme, Camille Washington-Ottombre

Environmental Science and Policy: Faculty Publications

In a global context of climate change and increased water scarcity, the development of efficient irrigation schemes in sub-Saharan Africa where rainfed agriculture still prevails could significantly support food security. However, developing efficient irrigation schemes is highly challenging and necessitates the resolution of a number of collective action problems. Since the 1980s, a large body of research has explored the conditions needed for successful collective action, sustainable use of the resource in irrigation schemes, and the development of efficient institutions. Although there is no agreed-upon definition of what successful, sustainable, or efficient governance schemes or institutions are, there is a …

Incorporating Climate Change Refugia Into Climate Adaptation In The Acadia National Park Region, Jennifer Smetzer, Toni Lyn Morelli

Second Century Stewardship Refugia Products

Climate change is predicted to have significant impacts on New England’s biodiversity. If emissions continue unabated, mean global temperature is predicted to rise by 3-5 ºC by the end of the century, and well beyond the range of natural variability. Changes are already evident in Acadia National Park (ACAD). Between 1895 and 2010, annual precipitation significantly increased in ACAD by 16% and temperatures by 0.8 ºC; the rate of temperature increase in the park is expected to be 3-6 times greater by 2100, particularly in inland portions. Identifying climate change refugia for representative species can provide valuable information for adapting …

Loss Of A Foundation Species, Eastern Hemlock (Tsuga Canadensis), May Lead To Biotic Homogenization Of Fungal Communities And Altered Bacterial Abundance In The Forest Floor, Aliza Fassler, Jesse Bellemare, Danielle D. Ignace

Biological Sciences: Faculty Publications

Tsuga canadensis (Eastern Hemlock) is a key forest foundation species that is currently declining across the eastern US due to attack by exotic insect species, primarily Adelges tsugae (Hemlock Woolly Adelgid). In the northeastern US, declining Eastern Hemlock stands are typically replaced by fast-growing deciduous Betula lenta (Black Birch) trees, altering ecosystem processes and ecological communities. In this study, we used an approach that substituted space for time to explore how the forest floor's soil organic horizon, macrofungal communities, and bacterial abundance might be altered following Eastern Hemlock replacement by Black Birch. We compared intact, mature Eastern Hemlock forest plots …
