As if to end the 1990s with a climatic exclamation point, the most recent boreal winter (December 1999–February 2000) was remarkably warm across much of the globe (Fig. 4). Last winter was the warmest ever recorded across the 48 contiguous United States: There were no regions of the United States that exhibited significant negative temperature anomalies, and a large fraction of the midwest region experienced warm anomalies exceeding 2 °C. The subsequent boreal spring was the warmest ever recorded over the same area, and globally, this spring was the fifth warmest in the instrumental record (National Climate Data Center, 2000b). Much, but not all, of the planet was also warm last winter, including Europe, central Africa, and mid-latitude oceans in both hemispheres. However, temperatures Figure 2.

In 1990, it was possible to state with reason- able certainty that the climate had warmed during the twentieth century. Global mean temperatures then continued to rise in the years leading up to the Rio de Janeiro summit and the adoption of the FCCC in 1992. By 1995, when the Second Assessment Report was released, the detection issue was more firmly resolved than was possible five years earlier. The IPCC’s Third Assessment Report, now in preparation and scheduled for release in April 2001, will surely contain even stronger statements on the significance of twentieth century climate change based on improved global estimates of Holocene climate variability such as shown in Figure 3.

These are essentially the same steps required to make quantitative predictions of the forced response of the climate system to future increases in greenhouse gases. A single variable such as global-mean temperature is not sufficient to differenti- ate a greenhouse-gas–induced climate change from other possible sources of variability. Large-scale numerical models provide the only means of estimating the answer to 1, above, and, in the absence of sufficient high-resolution, preindustrial climate data, the only practical way of assessing 2, above (IPCC, 1995, ch. 8; Has- selmann, 1997). Multivariate greenhouse fingerprints are derived by comparing patterns of variability in a numerical simula- tion in which greenhouse gas concentrations are kept fixed, thereby simulating natural variability, with another run of the same model in which greenhouse gases increase (IPCC, 1995, ch. 8; Hegerl et al., Figure 4.

The GSA Council acknowledges the many member-volunteers who, over the years, have stimulated growth and change through their involvement in the affairs of the Society. Each year, GSA asks for volunteers to serve on committees, and many highly qualified candidates express their willingness to serve. Not everyone can be appointed to the limited number of vacancies; however, members are reminded that there are also opportunities to serve in the activities and initiatives of the sections and divisions. Annually, the Council asks sections and divisions to convey the names of potential candidates for committee service to the Committee on Committees.

36 GSA TODAY, October 2000 2001 Research Grants Program for Students The primary role of the Research Grants Program is to provide partial support for research in earth science by graduate students at universities in the United States, Canada, Mexico, and Central America. GSA strongly encourages women, minorities, and persons with disabilities to participate fully in this grants program. Eligibility is restricted to GSA members. New application forms are available each fall in the geology departments of colleges and universities offering graduate degrees in earth sciences. Forms are mailed to GSA Campus Representatives, department secretaries, and chairpersons in the United States, Canada, and Mexico. Application forms and information are available on GSA’s Web page, www.geosociety.org. Applications may be downloaded from the Web but may not be submitted by facsimile or e-mail. They are also available upon request from the Research Grants Administrator, GSA, P.O. Box 9140, Boulder, CO 80301 or [email protected]. Please use only the current 2001 application and appraisal forms. Confidential evaluations from two faculty members are required from candidates and must accompany applications submitted. PLEASE USE THE “APPRAISAL OF APPLICANT” FORMS, WHICH ACCOMPANY THE 2001 APPLICATION FORMS. APPLICATION FORMS WILL NOT BE ACCEPTED BY FACSIMILE OR E-MAIL. GSA awarded more than $400,000 in grants in 2000. The grants went to 245 students doing research for advanced degrees. The average amount awarded was $1,622. The largest grant was $3,175, but there is no prede- termined maximum amount. Grants supported 41 percent of the applicants. Funding for this program is provided by a number of sources, including GSA’s Penrose and Pardee endowments, the National Science Founda- tion, industry, individual GSA members through the GEOSTAR and Research Grants funds, and numerous dedicated research funds that have been endowed at the GSA Foundation by members and families. The Committee on Research Grants will meet soon after the deadline to evaluate applications and award grants. In late April, GSA’s Chief Science Officer will inform all applicants for grants of the committee’s actions. APPLICANTS MUST BE MEMBERS OF GSA TO APPLY. ALL APPLICATIONS MUST BE SUBMITTED ON THE 2001 FORMS AND POSTMARKED BY FEBRUARY 1, 2001.

GSA TODAY, October 2000 45 A Model Experience in Montana

Al Fleming, Deerfield High School

his past year, I was honored to receive the 1999 Outstanding Earth Science Teacher Award for the state of Illinois, presented by the National Association of TGeoscience Teachers. As part of this award, GSA, through the John F. Mann Institute for Applied Geoscience, generously sponsored my participation this past summer in "Geology and Ecosystems," a field workshop offered by the National Min- erals Training Office and the National Forest Service. We were stationed out of the Judson Meade Geologic Field Station of Indiana University and spent the week working in the Northern Tobacco Root Mountains in southwestern Montana. The workshop presented me with personal and professional opportunities not readily available to a high school geology teacher, especially a flatlander like me. Hiking in the mountains of Montana is a real treat. At the same time, working at ele- vations over 8000 feet presented challenges to someone who spends most of his time hanging out at 650 feet above sea level. But the chance to work with surface outcrops was well worth the effort. Teaching in the glaciated terrain of northern Illi- nois, I must travel more than 60 miles to show my students actual bedrock. (Digging straight down through 400 feet of glacial drift would be a shorter trip, but much more time consuming!) Without a doubt, the most rewarding experience of the week was the opportunity to observe and work with other professional scientists. As the only teacher among this group of geologists, biologists, and soil scientists, it was exciting to see scientists modeling collaborative scientific investigative techniques consistent with many of the reform efforts taking place in science education. The way science is taught in this country is undergoing significant change. Curricula are being designed to soften the boundaries between biology, chemistry, physics, and the earth sciences, with an emphasis on broad unifying themes. Students bring their individual strengths to small groups, where they investigate real-life problems while constructing their own knowledge. Students’ understanding from these experiences is now assessed in a variety of ways, with equal emphasis on what they know and how well they are able to communicate their knowledge. Teachers facilitate these ventures into the natural world, providing guidance (not to mention an audience) and serving as one of many resources available to the students. The purpose of Geology and Ecosystems was to examine the components of the area’s ecosystems, with particular attention to the interaction of these components with respect to their geologic framework. During our group’s week in the field, we modeled many of the collaborative approaches to science that I try to teach my students. We looked closely at the interplay between geology, soils, and vegetation. For me, someone who considered soils and plants a nuisance in examining the geology of an area, it was enlightening to have a botanist accurately predict soil and bedrock types based on plant distribution, or to hear a soil scientist explain why certain plants grew in an area based on the bedrock geology. By pooling our shared expertise and experience, we were able to develop a broader, fuller understanding of that particular region of the Rocky Mountains. The opportunity provided me with not only content knowledge in the natural sciences, but more important, personal experience working with professional scientists. As a result of this experience, my own observations of how science is done in the field will have a lasting impact on my classroom instruction and, consequently, make a real difference in my students’ appreciation of science as a valuable human endeavor. ■

48 GSA TODAY, October 2000 Cenozoic Tectonics and Volcanism of Mexico edited by Hugo Delgado-Granados, Gerardo J. Aguirre-Diaz, Joann M. Stock, 2000

More than a dozen authors explore the Cenozoic evolution of Mexico, providing a key perspective on recent advances in the understanding of the tectonics and volcanic history of the country. Many of the papers focus on the relationship between the observed geology and the inferred plate motions. Attention is given to studies in and around the Rivera plate and the Jalisco region, recognizing that an understanding of this area could hold the key to the relationship between changes in plate tectonics at a trench and the effect on the geology of the overriding plate. A must-have volume for those interested in the continuing study of the geology of Mexico. SPE334, ISBN 0-8137-2334-5, 282 p., indexed, 2 plates $64.00, Member Price $51.20

Tectonics of the Coast Mountains, Southeastern Alaska and British Columbia edited by Harold H. Stowell and William C. McClelland, 2000

The geology of southeastern Alaska and coastal British Columbia has played a pivotal role in the recognition of terranes and the growth of the terrane concept, and the Coast Mountains in particular include some important and controversial terrane boundaries. This volume provides an overview of the accretionary and post-accretionary processes that occurred along these terrane boundaries in the western Coast Mountains between Skagway, Alaska, and Bella Coola, British Columbia. The authors use lithologic, geochemical, and isotopic data to correlate tectonostratigraphic packages separated by faults; use structural relations and ages of intrusions to suggest the timing of terrane accretion and the displacement history for shear zones and sutures; and use pressure-temperature-time data and modeling to constrain explanations for metamorphism. By emphasizing geochronologic, structural, stratigraphic, and petrologic data and interpretations, this volume delivers a comprehensive look at the Coast Mountains orogen.

Volcanic Hazards and Disasters in Human Antiquity edited by Floyd W. McCoy and Grant Heiken, 2000

Huge volcanic eruptions ravage civilizations by destroying cities and burying landscapes. The records of such disasters are preserved within and beneath tephra, as are the consequent alterations to human history by such cataclysmic events. These records also preserve the responses to such disasters—too often, a reoccupation of the same landscape, ignoring the hazards inherent in volcanism. This eight-chapter volume brings together geologists and archaeolo- gists (in the evolving scientific subdiscipline of archaeological geology, or geoarchaeology) to discuss the impacts of volcanic hazards and disasters on prehistoric and historic cultures at regional and local scales. Areas discussed range from Africa and Central America to Indonesia, England, Hawaii, and Greece. The result is a fascinating book for scientists of all disciplines.

Ancient Lake Creede edited by Philip M. Bethke and Richard L. Hay, 2000

Lake Creede was a late Oligocene closed-basin lake that existed in the moat of the Creede caldera in the central San Juan Mountains, Colorado. The lake evolved to moderate salinity, hosted brine shrimp, and precipitated ikaite (CaCO3•6H2O) on tufa mounds on the lake margins. Lake sediments comprise locally-derived volcanic ash and volcaniclastic material and contain varve-like beds of alternating siliciclastic and carbonate material. Authigenic pyrite is nearly ubiquitous. This book provides a comprehensive major update on the volcanic and geomorphic evolution of the central San Juans, examines the sedi- toll-free: 888-443-4472 mentation and diagenic history of the volcaniclastic and carbonate lake sediments, traces the stable iso- fax: 303-447-1133 topic evolution of the lake and formation waters, and examines the relationship between the lake and the Web: www.geosociety.org well-studied epithermal silver and base-metal mineralization in the Creede mining district.
