Our science is developing a new structure characterized by recognition that the Earth is a large, complex, interactive dynamic system in which all the processes that give it shape and form and that control its climate system are interdependent. Second, and perhaps more profound, is the recognition that global-scale processes not only affect human activity but are affected by it. The tenor of much Earth science research is shifting toward integrated approaches based on global-scale, interdisciplinary studies that account for the observed behavior of the whole Earth system, including biological phenomena and the linkages to socioeconomic processes. We are beginning to ask new questions, such as: "Can we manage the Earth to benefit humanity without causing its destabilization?" --JOHN C. MUTTER
