Water Follies: The Impact of Groundwater Pumping on the
Environment

Rivers and lakes are drying up.

Professor Robert Glennon has taught law at the University of
Arizona since 1985.In 1997, he was named the Morris K. Udall
Professor of Law and Public Policy. He specializes in
Water Law, Constitutional Law, and American Legal History.
Before joining the faculty at the UA, Dr. Glennon taught at the
University of Minnesota, the University of Illinois, and Wayne
State University. He has also taught in Puerto Rico and Japan. He
received his J.D. from Boston College and a Ph.D. in American
history from Brandeis University. He is a member of the bars of
Arizona, Massachusetts, and Michigan. Dr. Glennon has published
numerous articles on both the environment and law and is an oft-
quoted source about water resources and policy. He is the author
of the book, Water Follies: Groundwater Pumping and the
Fate of America's Fresh Waters, published by Island Press in 2002.

Driftwood and Napoleon's Hair: How geochemical "reading"
glasses can help elucidate the stories of enviornmental change at
the watershed scale

By; Patrick Louchouarn, Dept. of Earth & Environmental Sciences
& School of International & Public Affairs, Columbia University

Geochemical tools, organic and inorganic, can go beyond the
reductionist approach of detailing input functions of specific sources
of organic matter to aquatic systems, or elucidating the fate of such
compounds under varying environmental conditions. Organic and
inorganic geochemical approaches can in fact be used individually
or in combination to decipher shifts in environmental conditions that
occur at the watershed scale.

Examples of such approaches are provided in the study of large-
scale influences of anthropogenic activities on a temperate
estuarine system, a major equatorial river, flooded boreal soils, and
a sub-tropical freshwater reservoir. In all cases, geochemical
makers helped demonstrate (sometimes quantitatively)
environmental changes that occurred over just a few decades.
This approach has also been applied to study fundamental issues
of ocean circulation in sub-Arctic seas showing that Siberian and
North American boreal rivers export, via the surface Arctic waters,
substantial amounts of terrigenous organic matter to the North
Atlantic.

GC Talk Tuesday Feb. 18,2003

Professor Robert Strom, Lunar and Planetary Laboratory, will give a
colloquium presentation on Tuesday, February 18, 2003 at 3:30 p.m.
in the Space Sciences Bldg. Lecture Hall, Room 308. Professor Strom
will speak on "Global Warming: How Serious Is It?".

ABSTRACT:
The Earth has experienced relatively large natural climate variations
during its geologic history. Some of these climate changes have been
very abrupt. A large variety of evidence strongly suggests that Earth
is warming at an unprecedented rate. The greenhouse gas content of
the atmosphere has increased dramatically during the past two hundred
years and continues to rise at an increasing rate. It is now higher
than anytime during at least the past 1/2 million years. Earth's
mountain glaciers are melting at an alarming rate, and ocean
temperatures and sea level continue to rise. A variety of evidence
indicates that human activities are largely responsible for these
events. In fact, the root cause of most of the planet's environmental
woes is the enormous human population (6.2 billion people and
growing). Although many of the underlying principles of global
warming are relatively well determined, the long term consequences are
poorly understood. Even more uncertain and problematic is our
determination to do something about it.
