Earth system science (ESS) is the application of systems science to the Earth sciences. In particular, it considers interactions between the Earth's spheres—atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, biosphere, and, even, the magnetosphere—as well as the impact of human societies on these components. At its broadest scale, Earth system science brings together researchers across both the natural and social sciences, from fields including ecology, economics, geology, glaciology, meteorology, oceanography, paleontology, sociology, and space science. Like the broader subject of systems science, Earth system science assumes a holistic view of the dynamic interaction between the Earth's spheres and their many constituent subsystems, the resulting organization and time evolution of these systems, and their stability or instability. Subsets of Earth system science include systems geology and systems ecology, and many aspects of Earth system science are fundamental to the subjects of physical geography and climate science.

The Science Education Resource Center, Carleton College, offers the following description: Earth system science embraces chemistry, physics, biology, mathematics and applied sciences in transcending disciplinary boundaries to treat the Earth as an integrated system. It seeks a deeper understanding of the physical, chemical, biological and human interactions that determine the past, current and future states of the Earth. Earth system science provides a physical basis for understanding the world in which we live and upon which humankind seeks to achieve sustainability.

For millennia, humans have speculated how the physical and living elements on the surface of the Earth combine, with gods and goddesses frequently posited to embody specific elements. The notion that the Earth, itself, is alive was a regular theme of Greek philosophy and religion. Early scientific interpretations of the Earth system began in the field of geology, initially in the Middle East and China, and largely focused on aspects such as the age of the Earth and the large-scale processes involved in mountain and ocean formation. As geology developed as a science, understanding of the interplay of different facets of the Earth system increased, leading to the inclusion of factors such as the Earth's interior, planetary geology and living systems.

In many respects, the foundational concepts of Earth system science can be seen in the holistic interpretations of nature promoted by the 19th century geographer Alexander von Humboldt. In the 20th century, Vladimir Vernadsky (1863-1945) saw the functioning of the biosphere as a geological force generating a dynamic disequilibrium, which in turn promoted the diversity of life. In the mid-1960s, James Lovelock first postulated a regulatory role for the biosphere in feedback mechanisms within the Earth system. Initially named the Earth Feedback hypothesis, Lovelock later renamed it the Gaia hypothesis, and subsequently further developed the theory with American evolutionary theorist Lynn Margulis during the 1970s. In parallel, the field of systems science was developing across numerous other scientific fields, driven in part by the increasing availability and power of computers, and leading to the development of climate models that began to allow the detailed and interacting simulations of the Earth's weather and climate. Subsequent extension of these models has led to the development of Earth system models (ESMs) that include facets such as the cryosphere and the biosphere.

As an integrative field, Earth system science assumes the histories of a vast range of scientific disciplines, but as a discrete study it evolved in the 1980s, particularly at NASA, where a committee called the Earth System Science Committee was formed in 1983. The earliest reports of NASA's ESSC, Earth System Science: Overview (1986), and the book-length Earth System Science: A Closer View (1988), constitute a major landmark in the formal development of Earth system science. Early works discussing Earth system science, like these NASA reports, generally emphasized the increasing human impacts on the Earth system as a primary driver for the need of greater integration among the life and geo-sciences, making the origins of Earth system science parallel to the beginnings of global change studies and programs.

The Earth System

This video describes the four main components of the Earth system (atmosphere, biosphere, geosphere, hydrosphere), how matter is exchanged between the components, and how a change in some aspect of one part of the system will result in changes in other system components. We describe the Earth system in terms of reservoirs and flux between them and discuss how the movement of carbon occurs between system components.

A brief overview to the area of Earth Systems Science where we will be looking at the different spheres that make up Earth as a complex adaptive system.



Transcription:
Earth systems science is the interdisciplinary study of earth as a complex system, composed of multiple physical and biological process that interact within cycles or spheres to give rise to the overall state of the earth as an entire systems.

Of cause people have been studying earth for a long time, geologies study the formation of rocks, metrologies are interested in the atmosphere and so on,
With all of these different domains supported by the deep understanding of our physical environment that physics has built up over the past few centuries.

But it is only more recently that satellites have started to allow us to see earth as an entirety and human activity has begun to have a significant enough effect to alter earth systems making it increasingly important for us to be able to model and manage them.

From space we can view the net results of earths complex interactions and with high-tech sensors on land and in the ocean, we are getting an clear idea of its overall make up, from this researchers in different domains are discovering how their pieces of the puzzle are related to each other.

Earth systems science then tries to develop models that gives an integrated picture of how all these parts fit together, the first of these models is of earth as a systems in space with inputs and outputs of energy or radiation from the sun, with this energy being the primary factor in driving the dynamics process within the system.


As opposed to focusing on the static properties of earths individual components
Earth systems science instead takes a more dynamic view of the world, studying the ways energy and materials cycle through the different subsystems or what are called -spheres

Earths different sphere are largely defined by the different phases of mater they are composed of thus the atmosphere is composed of gasses, the hydrosphere of liquid water and the lithosphere solid minerals added to this is the biosphere
The sum of all biological material and processes.

Within each sphere a process called a cycles take place, for example in the lithosphere we have the rock cycle driven by the thermal energy within earth's interior that releases minerals through ocean ridges and volcanoes that are weathered as they cycle through earths crust and are eventual subducted returning to their origin



The hydro cycle driven by the thermal energy of the sun, cycles water between the earths surface and atmosphere through the process of evaporation, condensation and precipitation, this process helps to distribute moisture to support ecosystems at a variety of locations

The atmosphere is a layer of gases surrounding the planet that is held in place by gravity, it is the primary vehicle of temperature and climate regulation through the Cycle of carbon in and out of the atmosphere where it functions, through the green house effect to trap the suns heart.

The biosphere is the relatively thin layer of Earth's surface that supports all biological activity on earth. The biosphere is a system also characterized by the continuous cycling of matter and energy in the form of the flow of solar energy and nutrient mineral cycles.

Solar energy flows through the biosphere along a unidirectional path, as the suns energy is inputted through plant photosynthesis and process up through what are called trophic levels form primary producers to herbivores and on to predators and apex predators.

Along side the flow of energy through food webs it the cycling of mineral nutrients the core substances required for the construction of biological materials and processes, carbon, water, oxygen, nitrogen have been continuously cycled through the biosphere from one generation to the next for billions of years

These different spheres interact to create a unique state or ecosystem, an ecosystems is the combination of a community of biological organism and a particular physical environment with which they interact...

Earth system governance is a recently developed paradigm that builds on earlier notions of environmental policy and nature conservation, but puts these into the broader context of human-induced transformations of the entire earth system. It conceptualizes the system of formal and informal rules, rule-making mechanisms and actor-networks at all levels of human society (from local to global) that are set up to steer societies towards preventing, mitigating, and adapting to global and local environmental change and earth system transformation, within the normative context of sustainable development.

The notion of governance refers to forms of steering that are less hierarchical than traditional governmental policy-making (even though most modern governance arrangements will also include some degree of hierarchy), rather decentralized, open to self-organization, and inclusive of non-state actors that range from industry and non-governmental organizations to scientists, indigenous communities, city governments and international organizations.

The integrative new paradigm of earth system governance has evolved into an active research area that brings together a variety of social science disciplines including political science, sociology, economics, ecology, policy studies, geography, sustainability science, and law.

Major international conferences on ‘Earth System Governance’ have been held, or are being prepared in Amsterdam (2007, 2009), Berlin (2008, 2010), Colorado (2011), Lund (2012), Tokyo (2013) and Norwich (2014). In 2015, the 6th Annual Earth System Governance Conference will take place in Canberra. This conference is co-hosted by the Australian National University and the University of Canberra.

Workshops, summer schools, and training programmes have been organised in many places in Europe, Asia, and North America.

On 16–19 May 2011, more than twenty Nobel Laureates, several leading policy-makers and some of the world’s most renowned thinkers and experts on global sustainability met for the Third Nobel Laureate Symposium on Global Sustainability at the Royal Swedish Academy of Sciences in Stockholm. The Nobel Laureate Symposium concluded with the Stockholm Memorandum, calling for strengthening of Earth System Governance as a priority for coherent global action. This memorandum has been submitted to the High-level Panel on Global Sustainability appointed by the UN Secretary General and fed into the preparations for the 2012 UN Conference on Sustainable Development (Rio+20).

In 2009, the UN-sponsored global change research networks have set up a long-term research programme in earth system governance, the Earth System Governance Project. The Earth System Governance Project currently consists of a network of ca. 300 active and about 2,300 indirectly involved scholars from all continents, and is the largest social science research network in the area of governance and global environmental change. The Earth System Governance Project is essentially a scientific effort, but also aims to assist policy responses to the pressing problems of global environmental change. The International Project Office of the Earth System Governance Project is based at Lund University, Sweden.

Research centres on ‘Earth System Governance’ have been set up or designated at VU University Amsterdam; the Australian National University; Chiang Mai University; Colorado State University; Lund University; University of East Anglia; University of Oldenburg; the Stockholm Resilience Centre; the University of Toronto; the Tokyo Institute of Technology and Yale University. In addition, strong networks on earth system governance research exist in China, Latin America, Central and Eastern Europe, and Russia.

Description: In recent decades we have observed a significant reduction of the cryosphere due to anthropogenic climate change. The observed and predicted changes in the extent and amount of snow and ice will have major impacts on climate, ecosystems and human populations both at a local and global scale. This course will introduce students to the science behind climate change as well as the physical and chemical processes that govern components of the cryosphere, including snow, permafrost, sea ice, glaciers and ice sheets. Particular emphasis will be placed on the important role that each component plays in the larger climate system and potential feedbacks. We will also examine some of the social, economic and political impacts that the melting cryosphere will have on countries around the Arctic and also worldwide, such as access to new petroleum reserves, infrastructure damage due to melting permafrost, sea level rise and decreases in freshwater availability.

Systems science, systemology or systems theory is an interdisciplinary field that studies the nature of systems — from simple to complex — in nature, society, cognition, and science itself. The field aims to develop interdisciplinary foundations that are applicable in a variety of areas, such as psychology, biology, medicine, communication, business management, engineering, and social sciences.

Systems science covers formal sciences such as complex systems, cybernetics, dynamical systems theory, information theory, linguistics or systems theory. It has applications in the field of the natural and social sciences and engineering, such as control theory, operations research, social systems theory, systems biology, system dynamics, human factors, systems ecology, systems engineering and systems psychology. Themes commonly stressed in system science are (a) holistic view, (b) interaction between a system and its embedding environment, and (c) complex (often subtle) trajectories of dynamic behavior that sometimes are stable (and thus reinforcing), while at various 'boundary conditions' can become wildly unstable (and thus destructive). Concerns about Earth-scale biosphere/geosphere dynamics is an example of the nature of problems to which systems science seeks to contribute meaningful insights.

Since the emergence of general systems research in the 1950s, systems thinking and systems science have developed into many theoretical frameworks.

Systems analysis is the branch of systems science that analyzes systems, the interactions within those systems, and/or interaction with its environment, often prior to their automation as computer models. This field is closely related to operations research.

Systems design is the process of establishing and specifying the optimum system component configuration for achieving specific goal or objective. For example in computing, systems design can define the hardware and systems architecture which includes many sub-architectures including software architecture, components, modules, interfaces, and data, as well as security, information, and others, for a computer system to satisfy specified requirements.

System dynamics is an approach to understanding the behavior of complex systems over time. It offers simulation technique for modeling business and social systems, which deals with internal feedback loops and time delays that affect the behavior of the entire system. What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops and stocks and flows.

Systems engineering (SE) is an interdisciplinary field of engineering, that focuses on the development and organization of complex systems. It is the art and science of creating whole solutions to complex problems, for example: signal processing systems, control systems and communication system, or other forms of high-level modelling and design in specific fields of engineering.

There are several types of Systems Methodologies, that is, disciplines for analysis of systems. For example:
Soft systems methodology (SSM) : in the field of organizational studies is an approach to organisational process modelling, and it can be used both for general problem solving and in the management of change. It was developed in England by academics at the University of Lancaster Systems Department through a ten-year Action Research programme.
System development methodology (SDM) in the field of IT development is a variety of structured, organized processes for developing information technology and embedded software systems.
Viable systems approach (vSa) is a methodology useful for the understanding and governance of complex phenomena; it has been successfully proposed in the field of management, decision making, marketing and service.

Systems theory is an interdisciplinary field that studies complex systems in nature, society, and science. More specifically, it is a conceptual framework by which one can analyze and/or describe any group of objects that work in concert to produce some result.

Systems sciences are scientific disciplines partly based on systems thinking such as chaos theory, complex systems, control theory, cybernetics, sociotechnical systems theory, systems biology, systems chemistry, systems ecology, systems psychology and the already mentioned systems dynamics, systems engineering, and systems theory.
