Earth System Science

Science, 2001
O ne of the great scientific challenges of the 21st century is to forecast the future of planet Earth. As human activities push atmospheric carbon dioxide (CO2) and methane concentrations far beyond anything seen for nearly half a million years (prompting the strongest statement yet from the Intergovernmental Panel on Climate Change that human ...

The earth as a system

Behavioral Science, 1982
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

A dynamic earth observation system

Parallel Computing, 2003
The paper presents an overview of SARA/Digital Puglia (Synthetic Aperture Radar Atlas), a remote sensing environment that shows how grid technologies and high performance computing can be efficiently used to build dynamic earth observation systems for the management of huge quantities of data coming from space missions and for their on-demand ...

Genealogies of Earth System thinking

Nature Reviews Earth & Environment, 2020
In the first half of the 20th century, the Earth was already envisioned as a system of interacting parts intertwined with human cultural evolution. Historical sources of Earth Systems thinking can still be relevant in light of current and future trajectories, and may offer insights to inform and rethink present-day discourses and strategies.
