Since Hurricane Katrina, there has been an increasing concern that a changing climate will bring about more frequent and more intense extreme weather events. This concern has motivated scientists to investigate the connection between global warming and extreme events such as hurricanes. In this lecture, Dr. Greg Holland of the National Center for Atmospheric Research discusses the scientific evidence that suggests a connection between global warming and hurricanes and comments on the political ramifications of this connection.

Warren Wiscombe
"Chaos" and "fractals" are two terms signaling a scientific revolution that has taken place in the last 20 years. In this talk, NASA researcher Warren Wiscombe explains how ordinary objects and events such as snowflakes and snowboarding exhibit the characteristics of chaos. Additionally, Wiscombe describes how chaos and fractal theory can shed new light on long-standing scientific conundrums such as weather and climate, fluid flows, cells, and life itself.

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:
Jack Lousma
Viewing Earth from space provides a much-needed platform for understanding global change issues. As a former astronaut logging 1600 space flight hours, Jack Lousma is well-equiped to describe the process of space travel and the benefits of viewing Earth from space. In this lecture, Lousma recounts his experience as an astronaut and the lessons about Earth he has learned.

Robert W. Corell
The field of global change science is a relatively young field, developing out of the recognition of the sizable impact humans are making on the planet. In this lecture, Robert Corell, assistant director of the National Science Foundation, provides an overview of the scope of global change science and touches on its major contributions. In addition, Corell offers some comments about policies that can address global change issues.

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.
