Early Signs of the Depleting Ozone Layer
Date:

Author/s:
Peter Thacher
The enactment of the Montreal Protocol in 1987 is hailed as a success for international cooperation in general, and environmental policy in particular. In this talk, Dr. Peter Thacher, a retired UN diplomat, explains the circumstances surrounding the identification of the ozone hole problem and the subsequent agreement to curb CFC emissions, the leading contributor to ozone depletion. Dr. Thacher argues that there are lessons to be learned from this case-study that can be applied to future cases of cooperation on environmental issues.

Author/s:
Richard Rockwell
We are now in an unprecedented age where humans have become a force of global importance and where local human behavior has significant global impacts. In light of this new world order, Dr. Richard Rockwell of the University of Michigan addresses the issue of identifying and mitigating the negative impacts of human activity on the environment. These impacts, which Dr. Rockwell describes as large and growing, are and will continue to affect every individual, regardless of whether they directly contribute to the impacts or not.

Climate change gets the lion's share of media attention, but it is not the most certain, not the least reversible, and not the most significant (to date) of human-caused changes to the earth system. This talk , given by Stanford professor Dr. Peter Vitousek, examines the major components of human effects on Earth, with emphasis on the changing composition of the atmosphere, the transformation of Earth's surface by human activity, and the loss of biological diversity.

Walter Falcon
Much was left unsaid at the UNCED conference in Rio about the interactions among population growth, human deprivation, and resource use. Dr. Walter Falcon, director of Stanford's Institute for International Studies, develops these themes, drawing on his extensive knowledge of hunger, land use, and agriculture, and on his specific experiences in South and Southeast Asia.

Author/s:
Warren Washington
Computer models are currently relied upon to provide estimates of possible future changes in the Earth's climate. Results from these models were at the center of the global warming debate at the recent Earth Summit in Brazil. There was a great deal of controversy about whether modeling can yield insights into the planet's future. In this talk, Dr. Warren Washington, researcher at the National Center for Atmospheric Research, comments on the climate research community's views and the skeptical response.

Author/s:
Robert G. Woodmansee
Sustainability is a contentious topic, attracting a variety of views from different interest groups. In the American West, disagreements over what is needed to achieve sustainable ecosystems often pit ranchers against environmentalists and makes progress on policy and management difficult. In this lecture, Rob Woodmansee, a range ecologist at Colorado State University, discusses the competing views of sustainability. Woodmansee argues, "what you see depends on where you sit," and suggests that achieving a sustainable future must recognize and understand the many different perspectives.

Of the many pressing global change issues, none have as far-reaching effects as biodiversity loss. In this eloquent and passionate talk, Dr. Norman Myers explains why biodiversity is a crucial environmental issue and tells of efforts to find solutions to the problem of species extinction. In his talk, Dr. Myers pays specific attention to tropical forests, where biodiversity is greatest but most at risk.

Author/s:
Stephen H. Schneider
Dr. Stephen Schneider was one of the most notable and outspoken scientists on the topic of climate change. His moderate and scientific approach to explaining climate change has helped congressmen, journalists, and citizens understand the complex, and often contradictory, issues related to global warming. In this ever timely talk, Dr. Schneider goes over the many different portrayals of climate change in the media and explains how to distinguish hype from science. He argues that in order to have a functional democracy, voters must understand the basics of these important issues so that they can make informed decisions.
