In basic terms, global warming refers to a warming trend of
the Earth's near-surface atmosphere and its oceans. Scientific study has
shown that in the distant past global warming trends occurred due to natural
influences; however, today, because climate change and rising sea levels
have seen dramatic changes, and because human emissions of greenhouse gases
have increased significantly over the past 100 years, scientists are much
more concerned about global warming than ever. With the world's population
continuing to grow, the demand for energy will only increase, which will
continue to put a heavy demand on the Earth's natural resources. As a
result, there's no way around global warming being a political issue, and,
no pun intended, the debate about global warming continues to heat up. To
remain objective it is key for individuals to know what is fact or fiction,
which is the main theme of this program. This "interchange" introduces us to
Stephen H. Schneider, Ph.D., who is an expert climatologist and
Professor of Environmental Biology and Global Change at Stanford University;
he co-edited the acclaimed book, Climate Change Policy: A Survey.
Here he explains how individuals can determine what's truth and what's
propaganda in the scientific wars regarding the environmental status of
planet Earth. 08DR/CL SCA 30 min.
