Eyewitness to Global Warming

Video description:

The fourth person ever to reach both poles, Will Steger is known by many titles educator, activist, photographer, and former Explorer-in-Residence for National Geographic. He presents a visual account of the global warming induced changes that hes witnessed firsthand in Arctic regions over four decades of polar exploration.

Global Warming: What Do We Know and What Should We Do?

Video description:

In 2007, an international group of experts completed a definitive assessment of recent research on climate change science. The Intergovernmental Panel on Climate Change (IPCC) calls warming of the climate system "unequivocal" and attributes most of the observed recent global warming to human activities, with a confidence level of 90% or more. As human activities continue to modify the climate system, what will the implications be for rising sea level, hurricanes, and water supply? This talk first summarizes key scientific findings and then examines policy options. Worldwide emissions of the greenhouse gases that cause climate change continue to increase each year. Nations will accept constraints on their freedom to emit carbon dioxide and other greenhouse gases only when they are satisfied that they are being treated justly and equitably. Ethical concerns underlie the differing rights and obligations of both developed and developing countries. Intergenerational equity requires people today to consider the planet that their descendants will inherit. The prospect of intentional geoengineering to counter human-caused climate change also raises profound questions of equity and ethics.

U.S. Energy Policy and Global Warming

Video description:

Elton Sherwin, Senior Managing Director of Ridgewood Capital, discusses the federal energy policy and what should be done to address global warming. The Energy Seminar meets weekly during the academic year. For a list of upcoming talks, visit the events page at the Woods Institute for the Environment website.

Global Warming - What do the numbers show?

Video description:

Dr. John R. Christy is Professor and Director of the Earth System Science Center at the University of Alabama in Huntsville where he began studying global climate issues in 1987. In November 2000 Gov. Don Siegelman appointed him to be Alabama's State Climatologist. In 1989 Dr. Roy W. Spencer, a NASA/Marshall scientist, and Christy developed a global temperature data set from microwave data observed from satellites beginning in 1979. For this achievement, the Spencer-Christy team was awarded NASA's Medal for Exceptional Scientific Achievement in 1991. In 1996, they were selected to receive a Special Award by the American Meteorological Society "for developing a global, precise record of earth's temperature from operational polar-orbiting satellites, fundamentally advancing our ability to monitor climate."

Copenhagen: The Meeting and its Consequences

Video description:

Meg Caldwell, Stanford Director of Environmental and Natural Resources Law and Policy Program, discusses the results of the Copenhagen negotiations as well as explaining the troubles facing the oceans and their inhabitants.

Just say no to carbon emissions!

Video description:

We're all potentially billionaires when it comes to solar energy. The trick is learning how to convert sunlight to electricity using cheap and plentiful materials. Ramamoorthy Ramesh, an innovative materials scientist at Berkeley Lab, will discuss how he and other researchers are working to make photovoltaic cells using the most abundant elements in the Earth's crust -- materials that are literally as common as dirt.

Making a Difference: Individuals Taking Local Action on Global Warming

Video talk description:

The basic scientific ideas and observational record of rising greenhouse gas (GHG) levels provide potent reasons for concern and action on the climate and clean energy challenge. Since the emissions of GHGs are inextricably linked to fundamental areas of human activity--energy generation, waste disposal, agriculture, etc. -- action is needed at all levels: international, federal, state, municipal, institutional, and individual. Local action by city and county governments, institutions, and individuals reveals exemplary innovation and the important role of public engagement. The Silicon Valley's Sierra Club Chapter -- the Loma Prieta Chapter -- has developed a comprehensive Climate Action Campaign of local action to reduce regional GHG emissions through public engagement. The program has successfully attracted a large number of concerned individuals and consists of four initiatives: An Education and Outreach initiative includes expert lectures to community groups and booths at community events. The Cool Cities Campaign forms teams of residents in each city and county to advocate for local government action. The Climate Action Team initiative combines trainings with social support events to enable individuals to reduce their own emissions and to then take these ideas to institutions where they have a personal connection. A fourth initiative to reduce local barriers to solar power has led to large reductions in solar permit fees charged by over 72 cities. In this talk, we will discuss the Climate Action Campaign as a case study in local action and discuss concrete examples of how individuals can address humanity's historic climate challenge.

Using Thorium Energy to Address Environmental Problems

Video description:

Presented by Robert Hargraves. Mankind's fossil fuel burning releases CO2 into the atmosphere, contributing to global warming and deadly air pollution. Natural resources are rapidly being depleted by world population growth. Safe, inexpensive energy from the liquid fluoride thorium reactor can stop much global warming and raise prosperity of humanity to adopt US and OECD lifestyles, which include lower, sustainable birth rates.

Climate Change Forum: How Low Can We Go?

Video description:

Preventing dangerous climate change may require very deep reductions of greenhouse gases. Several countries and scientists have proposed on the basis of assessing climate risks that limiting the increase of global mean temperature to 2 degrees Celsius (3.6 degrees Fahrenheit) would be necessary. A critical question is whether such targets can still be achieved - and if so - how?

The Hurricane-Climate Connection

Video lecture description:

In this American Meteorological Society video, Kerry Emanuel, professor of atmospheric and planetary sciences at the Massachusetts Institute of Technology, examines the link between global warming and a perceived increase in severe weather. After Hurricane Katrina, this link became a critical debate topic in the science and policy arenas. While sea surface temperature plays a role in tropical storm intensity, it represents only part of the complex puzzle. Professor Emanuel details an emerging theory that suggests hurricanes and typhoons may play a major, and heretofore, unexpected role in climate dynamics.
