EARTHSYS 11Q. Sustainability And Social Justice. 3 Units.

At its core, sustainability is a conversation about equity. Equity between people today and people tomorrow. Equity between the many diverse people today who are all trying to pursue their hopes and dreams. Equity between human beings and the myriad other living creatures we share this planet with. Movements for environmental sustainability and social justice share a concern for equity, but have largely evolved in parallel. Mounting evidence however shows that environmental and social change are almost always inextricably linked, and the climate crisis is pushing together these two areas of study like never before. That is good news, but tough questions remain. What happens when the environmental costs of personal freedom can no longer be sustained? Should the needs of the many always outweigh the needs of the few? Are we responsible for repairing the injustices of our parents' and grandparents' generations? Where are the win-win solutions? In this interdisciplinary seminar, we will explore the theory and practice of sustainability and social justice, examining case studies where they have intersected, and where they have not. Readings will draw from sustainability science, environmental justice, environmental ethics, religious studies, social psychology, and ecological economics. Through weekly readings, discussions, and journal writing, students will develop a personal sustainability manifesto and analyze a policy, technology, or social movement through the lens of social and environmental sustainability.

EARTHSYS 12SC. Environmental and Geological Field Studies in the Rocky Mountains. 2 Units.

The Rocky Mountain area, ecologically and geologically diverse, is being strongly impacted by changing land-use patterns, global and regional environmental change, and societal demands for energy and natural resources. This three-week field program emphasizes coupled environmental and geological problems in the Rocky Mountains and will cover a broad range of topics including the geologic origin of the American West from three billion years ago to the recent; paleoclimatology and the glacial history of this mountainous region; the long- and short-term carbon cycle and global climate change; and environmental issues in the American West that are related to changing land-use patterns and increased demand for its abundant natural resources. These broad topics are integrated into a coherent field study by examining earth/environmental science-related questions in three different settings: 1) the three-billion-year-old rocks and the modern glaciers of the Wind River Mountains of Wyoming; 2) the sediments in the adjacent Wind River basin that host abundant gas and oil reserves and also contain the long-term climate history of this region; and 3) the volcanic center of Yellowstone National Park and mountainous region of Teton National Park, and the economic and environmental problems associated with gold mining and extraction of oil and gas in areas adjoining these national parks. Students will complete six assignments based upon field exercises, working in small groups to analyze data and prepare reports and maps. Lectures will be held in the field prior to and after fieldwork. Note: This course involves one week of backpacking in the Wind Rivers and hiking while staying in cabins near Jackson Hole, Wyoming, and horseback riding in the Dubois area of Wyoming. Students must arrive in Salt Lake City on Monday, Sept. 1. (Hotel lodging will be provided for the night of Sept. 1, and thereafter students will travel as a Sophomore College group.) We will return to campus on Sunday, Sept. 21. Sophomore College Course: Application required, due noon, April 7, 2015. Apply at http://soco.stanford.edu.

EARTHSYS 46Q. Environmental Impact of Energy Systems: What are the Risks?. 3 Units.

In order to reduce CO2 emissions and meet growing energy demands during the 21st Century, the world can expect to experience major shifts in the types and proportions of energy-producing systems. These decisions will depend on considerations of cost per energy unit, resource availability, and unique national policy needs. Less often considered is the environmental impact of the different energy producing systems: fossil fuels, nuclear, wind, solar, and other alternatives. One of the challenges has been not only to evaluate the environmental impact but also to develop a systematic basis for comparison of environmental impact among the energy sources. The course will consider fossil fuels (natural gas, petroleum and coal), nuclear power, wind and solar and consider the impact of resource extraction, refining and production, transmission and utilization for each energy source.

EARTHSYS 263E. International Climate Negotiations: Unpacking the Road to Paris. 3 Units.

Interested in what's going on with international climate negotiations, why it has proven so difficult to reach a meaningful agreement? Wondering whether or not another UN agreement is even a meaningful part of climate policy in 2015? This course traces the history of climate negotiations from the very first awareness of the problem of climate change, through the Kyoto Protocol and Copenhagen Accord, to the current state of international negotiations in the lead-up to the 21st Conference of the Parties meeting in Paris in December 2015. The course covers fundamental concepts in climate change science and policy, international law and multilateral environmental agreements, as well as key issues of climate finance, climate justice, equity, adaptation, communication, and social movements that together comprise the subjects of debate in the negotiations. We will discuss all the key facets of what's being negotiated in Paris and prepare students to follow the outcome of the negotiation in detail. Students also participate in a three-day mock conference of the parties. By application only.
