Scientific study of the Earth's spheres and their natural integrated systems

An ecological analysis of CO
2 in an [ecosystem](/source/Ecosystem). As [systems biology](/source/Systems_biology), [systems ecology](/source/Systems_ecology) seeks a [holistic](/source/Holistic) view of the interactions and transactions within and between biological and ecological systems.

**Earth system science** (**ESS**) is the application of [systems science](/source/Systems_science) to the [Earth](/source/Earth_science).[1][2][3][4] In particular, it considers interactions and 'feedbacks', through material and energy fluxes, between the Earth's sub-systems' cycles, processes and "spheres"—[atmosphere](/source/Atmosphere), [hydrosphere](/source/Hydrosphere), [cryosphere](/source/Cryosphere),[5] [geosphere](/source/Geosphere), [pedosphere](/source/Pedosphere), [lithosphere](/source/Lithosphere), [biosphere](/source/Biosphere),[6] and even the [magnetosphere](/source/Magnetosphere)[7]—as well as the impact of human societies on these components.[8] At its broadest scale, Earth system science brings together researchers across both the [natural](/source/Natural_science) and [social](/source/Social_science) sciences, from fields including [ecology](/source/Ecology), [economics](/source/Economics), [geography](/source/Geography), [geology](/source/Geology), [glaciology](/source/Glaciology), [meteorology](/source/Meteorology), [oceanography](/source/Oceanography), [climatology](/source/Climatology), [paleontology](/source/Paleontology), [sociology](/source/Sociology), and [space science](/source/Space_science).[9] Like the broader subject of [systems science](/source/Systems_science), Earth system science assumes a [holistic view](/source/Holism_in_science) of the dynamic interaction between the Earth's [spheres](/source/Outline_of_earth_science#Earth's_spheres) and their many constituent subsystems fluxes and processes, the resulting [spatial organization](/source/Self-organization) and time evolution of these systems, and their variability, stability and instability.[10][11][12] Subsets of Earth System science include [systems geology](/source/Systems_geology)[13][14] and [systems ecology](/source/Systems_ecology),[15] and many aspects of Earth System science are fundamental to the subjects of [physical geography](/source/Physical_geography)[16][17] and [climate science](/source/Climatology).[18]

## Definition

The [Science Education Resource Center](/source/Science_Education_Resource_Center), [Carleton College](/source/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".[19]

Earth System science has articulated four overarching, definitive and critically important features of the Earth System, which include:

1. Variability: Many of the Earth System's natural 'modes' and variabilities across space and time are beyond human experience, because of the stability of the recent Holocene. Much Earth System science therefore relies on studies of the Earth's past behaviour and models to anticipate future behaviour in response to pressures.

1. Life: Biological processes play a much stronger role in the functioning and responses of the Earth System than previously thought. It appears to be integral to every part of the Earth System.

1. Connectivity: Processes are connected in ways and across depths and lateral distances that were previously unknown and inconceivable.

1. Non-linear: The behaviour of the Earth System is typified by strong non-linearities. This means that abrupt change can result when relatively small changes in a 'forcing function' push the System across a '[threshold](/source/Planetary_boundaries)'.

## History

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.[20]

Early scientific interpretations of the Earth system began in the field of [geology](/source/Geology), initially in the Middle East[21] and China,[22] and largely focused on aspects such as the [age of the Earth](/source/Age_of_the_Earth) and the large-scale processes involved in [mountain](/source/Mountain_formation) and [ocean](/source/Origin_of_water_on_Earth) formation. As [geology developed as a science](/source/History_of_geology), understanding of the interplay of different facets of the Earth system increased, leading to the inclusion of factors such as the [Earth's interior](/source/Structure_of_the_Earth), [planetary geology](/source/Formation_and_evolution_of_the_Solar_System), [living systems](/source/Biosphere) and [Earth-like worlds](/source/Earth_analog).

In many respects, the foundational concepts of Earth System science can be seen in the natural philosophy 19th century geographer [Alexander von Humboldt](/source/Alexander_von_Humboldt).[23] In the 20th century, [Vladimir Vernadsky](/source/Vladimir_Vernadsky) (1863–1945) saw the functioning of the [biosphere](/source/Biosphere) as a geological force generating a dynamic disequilibrium, which in turn promoted the diversity of life.

In parallel, the field of [systems science](/source/Systems_science) was developing across numerous other scientific fields, driven in part by the increasing availability and [power](/source/Computer_performance) of [computers](/source/Computer), and leading to the development of [climate models](/source/Climate_model) that began to allow the detailed and interacting [simulations](/source/Numerical_weather_prediction) of the Earth's [weather](/source/Weather) and [climate](/source/Climate).[24] 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.[25]

In 1983 a [NASA](/source/NASA) committee called the Earth System Science Committee was formed. The earliest reports of NASA's ESSC, [*Earth System Science: Overview*](http://babel.hathitrust.org/cgi/pt?id=uiug.30112104410706;view=1up;seq=3) (1986), and the book-length [*Earth System Science: A Closer View*](https://books.google.com/books?id=Vj4rAAAAYAAJ&pg=PA173) (1988), constitute a major landmark in the formal development of Earth system science.[26] 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](/source/Global_change) studies and programs.

## Climate science

Climatology and climate change have been central to Earth System science since its inception, as evidenced by the prominent place given to climate change in the early NASA reports discussed above. The Earth's [climate system](/source/Climate_system) is a prime example of an emergent property of the whole planetary system, that is, one which cannot be fully understood without regarding it as a single integrated entity. It is also a system where human impacts have been growing rapidly in recent decades, lending immense importance to the successful development and advancement of Earth System science research. As just one example of the centrality of [climatology](/source/Climatology) to the field, the mission statement of one of the earliest centers for Earth System science research, the Earth System Science Center at Pennsylvania State University, reads, "the Earth System Science Center (ESSC) maintains a mission to describe, model, and understand the Earth's climate system".[27]

This section is an excerpt from [Climate system](/source/Climate_system).[[edit](https://en.wikipedia.org/w/index.php?title=Climate_system&action=edit)]

The five components of the climate system all interact. They are the [atmosphere](/source/Atmosphere_of_Earth), the [hydrosphere](/source/Hydrosphere), the [cryosphere](/source/Cryosphere), the [lithosphere](/source/Lithosphere) and the [biosphere](/source/Biosphere).[28]: 1451

Earth's [climate system](/source/Climate_system) is a [complex system](/source/Complex_system) with five interacting components: the [atmosphere](/source/Atmosphere_of_Earth) (air), the [hydrosphere](/source/Hydrosphere) (water), the [cryosphere](/source/Cryosphere) (ice and permafrost), the [lithosphere](/source/Lithosphere) (earth's upper rocky layer) and the [biosphere](/source/Biosphere) (living things).[28]: 1451 *[Climate](/source/Climate)* is the statistical characterization of the climate system.[28]: 1450 It represents the average [weather](/source/Weather), typically over a period of 30 years, and is determined by a combination of processes, such as [ocean currents](/source/Ocean_current) and wind patterns.[29][30] Circulation in the atmosphere and oceans transports heat from the [tropical regions](/source/Tropical_regions) to regions that receive less energy from the Sun. [Solar radiation](/source/Solar_radiation) is the main driving force for this circulation. The [water cycle](/source/Water_cycle) also moves energy throughout the climate system. In addition, certain chemical elements are constantly moving between the components of the climate system. Two examples for these [biochemical cycles](/source/Biogeochemical_cycle) are the [carbon](/source/Carbon_cycle) and [nitrogen cycles](/source/Nitrogen_cycle).

The climate system can change due to [internal variability](/source/Climate_variability) and [external forcings](/source/Radiative_forcing). These external forcings can be natural, such as [variations in solar intensity](/source/Solar_activity_and_climate) and volcanic eruptions, or caused by humans. Accumulation of [greenhouse gases](/source/Greenhouse_gas) in the atmosphere, mainly being emitted by people burning [fossil fuels](/source/Fossil_fuel), is causing [climate change](/source/Climate_change). Human activity also releases cooling [aerosols](/source/Aerosols), but their net effect is far less than that of greenhouse gases.[28]: 1451 Changes can be amplified by [feedback processes](/source/Climate_change_feedback) in the different climate system components.

## Education

Earth System science can be studied at a postgraduate level at some universities. In general education, the [American Geophysical Union](/source/American_Geophysical_Union), in cooperation with the [Keck Geology Consortium](/source/Keck_Geology_Consortium) and with support from five divisions within the [National Science Foundation](/source/National_Science_Foundation), convened a workshop in 1996, "to define common educational goals among all disciplines in the Earth sciences". In its report, participants noted that, "The fields that make up the Earth and space sciences are currently undergoing a major advancement that promotes understanding the Earth as a number of interrelated systems". Recognizing the rise of this [systems approach](/source/Systems_approach), the workshop report recommended that an Earth System science curriculum be developed with support from the National Science Foundation.[31]

In 2000, the Earth System Science Education Alliance (ESSEA) was begun, and currently includes the participation of 40+ institutions, with over 3,000 teachers having completed an ESSEA course as of fall 2009".[32]

## Related concepts

The concept of *earth system law* (still in its infancy as of 2021) is a sub-discipline of [earth system governance](/source/Earth_system_governance), itself a subfield of earth system sciences analyzed from a social sciences perspective.[33]
