Effects of Past Global Change on Life NATIONAL ACADEMY PRESS 2101 Constitution Avenue, N.W. Washington, DC 20418 NOTICE: The project that is the subject of this report was approved by the Governing Board of the National Research Council, whose members are drawn from the councils of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The members of the committee responsible for the report were chosen for their special competencies and with regard for appropriate balance. This report has been reviewed by a group other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Robert M. White is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and of advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce Alberts and Dr. Robert M. White are chairman and vice chairman, respectively, of the National Research Council. Support for this activity was provided by the Department of Energy, the National Science Foundation, the U.S. Geological Survey, and the National Oceanic and Atmospheric Administration.

Effects of Past Global Change on Life Preface This report is part of a series, Studies in Geophysics, that has been carried out over the past 15 years to provide (1) a source of information from the scientific community to aid policymakers on decisions on societal problems that involve geophysics and (2) assessments of emerging research topics within the broad scope of geophysics. An important part of such reports is an evaluation of the adequacy of current geophysical knowledge and the appropriateness of current research programs in addressing needed information. The study "Effects of Past Global Change on Life" is designed to help provide a scientific framework to assist the evaluation of the possible impacts of present and future global changes on the biosphere. Such a framework is based on the geologic record, which provides a unique, long-term history of changes in the global environment and of the impact of these changes on life. Because organisms are intimately related to their environment, we can infer that environmental changes of the past will have molded the history of life, and the geologic record confirms this inference for a wide range of temporal and spatial scales. The geologic record also reveals how particular kinds of environmental change have caused species to migrate, become extinct, or give rise to new species. More generally, it shows that many kinds of species and ecosystems are naturally fragile, and therefore transient, whereas other kinds are inherently more stable. The topic was initiated by the Geophysics Study Committee in consultation with the liaison representatives of the federal agencies that support the committee, relevant boards and committees within the National Research Council, and members of the scientific community. While this report was being completed, the Geophysics Study Committee ceased operations and its parent Board on Earth Sciences and Resources assumed the responsibility for the completion of this report. The preliminary scientific findings of the authored background chapters were presented at a symposium during October 1989 meeting of the Geological Society of America. In completing their chapters, the authors had the benefit of discussions at this symposium as

Effects of Past Global Change on Life well as the comments of several scientific referees. Ultimate responsibility for the individual chapters, however, rests with the authors. The Overview of the study draws from the scientific materials presented in the authored chapters and from other materials available in the traditional scientific literature to summarize the subject. The Overview also formulates conclusions and recommendations. In preparing the Overview, the panel chairmen had the benefit of meetings that took place at the symposium, comments of the panel, and the comments of scientists, who reviewed the report according to procedures established by the National Research Council's Report Review Committee. Responsibility of the Overview rests with the Board on Earth Sciences and Resources and the chairman and two co-vice chairmen of the panel.
