Rephrased Text: Earth System Science (ESS) is an increasingly prominent interdisciplinary field focused on understanding the Earth's structure and function as a dynamic, complex system. This discussion traces the origins and evolution of ESS, highlighting its role in enhancing our knowledge of global [[Change]]. Influenced by early studies of biosphere-geosphere interactions and perspectives such as the Gaia hypothesis, ESS took shape in the 1980s in response to calls for a more comprehensive "science of the Earth." The establishment of the International Geosphere-Biosphere Programme soon followed, fostering unprecedented international collaboration and disciplinary integration. ESS has introduced key concepts to the global-change discourse, including the Anthropocene, tipping points, and planetary boundaries. Looking ahead, its greatest challenge lies in fully integrating biophysical processes with human dynamics to develop a holistic understanding of the Earth system. Relation to Cybernetics: Yes, ESS relates to cybernetics, particularly in how it views the Earth as a complex, adaptive system with feedback loops, self-regulation, and emergent properties--core concepts in cybernetics. The Gaia hypothesis, which influenced ESS, aligns with cybernetic principles by suggesting that Earth's biological and geophysical processes interact in a self-regulating manner. Additionally, ESS's focus on modelling global systems, understanding stability and tipping points, and integrating human and natural dynamics resonates with cybernetics' study of [[Control]], communication, and adaptation within systems. `Concepts:` `Knowledge Base:`
