The planet Earth is a mixed living and nonliving system. It is the suprasystem of all supranational systems as well as the total ecological system, with all its living and nonliving components. The Earth is studied in this article in terms of a general theory of all concrete systems, with special attention to the important subset of living systems. The

Climate research today is ultimately driven by the need for a better understanding of the impacts of human activities on ecological, hydrological and socioeconomic systems. Theory and model development and testing are required in order to understand climate itself, and its impacts.

Earth system models are important research tools for improving understanding of the climate system and for simulating climate projections. This chapter is devoted to the basic construction principles and challenges of such models, whereas application examples are provided in companion chapters. Since they still do not incorporate the full complexity of

Hardware system of the Earth Simulator
Parallel Computing, 2004The Earth Simulator (ES), developed under the Japanese government's initiative "Earth Simulator project", is a highly parallel vector supercomputer system. In this paper, an overview of ES, its architectural features, hardware technology and the result of performance evaluation are described.In May 2002, the ES was acknowledged to be the most powerful ...

10Be and 14C in the Earth system
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1987Abstract In a very short period of time, 10Be data have significantly improved our knowledge in various fields of Earth and planetary sciences. Examples are: (a) solar modulation of isotope production, revealed in 10Be ice-core profiles; (b)geomagnetic m odulation of isotope production, revealed in 10Be ice-core (from the past 10 ka ...

Earth systems engineering and management
IEEE Technology and Society Magazine, 2000The impact of human activities on natural systems has grown to the point that we need to engage consciously in earth systems engineering and management. I address why this is the case, and what I mean by such a provocative term. In addition, I explore what we can learn from relevant experience, and how this daunting task should be approached.

Tidal effects in the earth–moon system and the earth's rotation
Celestial Mechanics and Dynamical Astronomy, 1999The author derives analytical expressions for tidal torques on a non-rigid planet, which perturb the rotation of the planet. These expressions are used to obtain secular and periodic perturbations of Euler's angles for the Earth's rotation. The secular effects caused by the tidal dissipation, which do not exist in the rigid planet model, can be very ...
