Holistic Understanding

The global society of today struggles with grand challenges, such as climate change, the degradation of ecosystems, and the loss of bio- and geodiversity, as identified in several documents. The search for solutions to these and other problems on the way to sustainable development necessarily involves a better understanding of the Earth system and its dynamics. The Earth system is composed of five highly dependent and interrelated subsystems that exchange matter and energy. This notion is at the base of what in the literature is named Earth System Science (ESS). Humanity has been profoundly altering the dynamics of this system, leading to the proposal of a new geological epoch—the Anthropocene. Developing a holistic understanding of the complex and tangled relationships between subsystems and the role of human impacts is the target of study of Earth System Education (ESE). With the assumptions of ESS, ESE is emerging as a new approach in science education. Based on a deep knowledge of the planet and the development of specific competencies, such as system thinking, it is possible to perform more actively and consciously in the relationships that citizens develop with the Earth system, enabling the existence of a more viable future for humanity.

Global Biogeochemical Cycles

<p>Despite being major players on the global biogeochemical cycles, microorganisms are generally not included in holistic views of Earth’s system. The Microbial Conveyor Belt is a conceptual framework that represents a recurrent and cyclical flux of microorganisms across the globe, connecting distant ecosystems and Earth compartments. This long-range dispersion of microorganisms directly influences the microbial biogeography, the global cycling of inorganic and organic matter, and thus the Earth system’s functioning and long-term resilience. Planetary-scale human impacts disrupting the natural flux of microorganisms pose a major threat to the Microbial Conveyor Belt, thus compromising microbial ecosystem services. Perturbations that modify the natural dispersion of microorganisms are, for example, the modification of the intensity/direction of air fluxes and ocean currents due to climate change, the vanishing of certain dispersion vectors (e.g., species extinction or drying rivers) or the introduction of new ones (e.g., microplastics, wildfires). Transdisciplinary approaches are needed to disentangle the Microbial Conveyor Belt, its major threats and their consequences for Earth´s system resilience.</p>

<p>The Earth System Grid Federation (ESGF) is a globally distributed e-infrastructure for the hosting and dissemination of climate-related data.  ESGF was originally developed to support the community in the analysis of CMIP5 (5th Coupled Model Intercomparison Project) data in support of the 5th Assessment report made by the IPCC (Intergovernmental Panel on Climate Change).  Recognising the challenge of the large volumes of data concerned and the international nature of the work, a federated system was developed linking together a network of collaborating data providers around the world. This enables users to discover, download and access data through a single unified system such that they can seamlessly pull data from these multiple hosting centres via a common set of APIs.  ESGF has grown to support over 16000 registered users and besides the CMIPs, supports a range of other projects such as the Energy Exascale Earth System Model, Obs4MIPS, CORDEX and the European Space Agency’s Climate Change Initiative Open Data Portal.</p><p>Over the course of its evolution, ESGF has pioneered technologies and operational practice for distributed systems including solutions for federated search, metadata modelling and capture, identity management and large scale replication of data.  Now in its tenth year of operation, a major review of the system architecture is underway. For this next generation system, we will be drawing from our experience and lessons learnt running an operational e-infrastructure but also considering other similar systems and initiatives.  These include for example, ESA’s Earth Observation Exploitation Platform Common Architecture, outputs from recent OGC Testbeds and Pangeo (https://pangeo.io/), a community and software stack for the geosciences.   Drawing from our own recent pilot work, we look at the role of cloud computing with its impact on deployment practice and hosting architecture but also new paradigms for massively parallel data storage and access, such as object store. The cloud also offers a potential point of entry for scientists without access to large-scale computing, analysis, and network resources.  As trusted international repositories, the major national computing centres that host and replicate large corpuses of ESGF have increasingly been supporting a broader range of domains and communities in the Earth sciences. We explore the critical role of standards for connecting data and the application of FAIR data principles to ensure free and open access and interoperability with other similar systems in the Earth Sciences.</p>

Dryland Degradation and Expansion: Implications for Mexican Policies from the Earth System Perspective

Despite international efforts to stop dryland degradation and expansion, current dryland pathways are predicted to result in large-scale migration, growing poverty and famine, and increasing climate change, land degradation, conflicts and water scarcity. Earth system science has played a key role in analysing dryland problems, and has been even incorporated in global assessments such as the ones made by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. However, policies addressing dryland degradation, like the ‘Mexican programme for the promotion of sustainable land management’, do not embrace an Earth system perspective, so they do not consider the complexity and non-linearity that underlie dryland problems. By exploring how this Mexican programme could integrate the Earth system perspective, this paper discusses how ’Earth system’ policies could better address dryland degradation and expansion in the Anthropocene.

Abstract. The vehicles that fly the satellite into a model of the Earth system are observation operators. They provide the link between the quantities simulated by the model and the quantities observed from space, either directly (spectral radiance) or indirectly estimated through a retrieval scheme (biogeophysical variables). By doing so, observation operators enable modellers to properly compare, evaluate, and constrain their models with the model analogue of the satellite observations. This paper provides the formalism and a few examples of how observation operators can be used in combination with data assimilation techniques to better ingest satellite products in a manner consistent with the dynamics of the Earth system expressed by models. It describes commonalities and potential synergies between assimilation and classical retrievals. This paper explains how the combination of observation operators and their derivatives (linearizations) form powerful research tools. It introduces a technique called automatic differentiation that greatly simplifies both the development and the maintenance of code for the evaluation of derivatives. Throughout this paper, a special focus lies on applications to the carbon cycle.

Modern western political thought revolves around globality, focusing on the partitioning and the connecting up of the earth’s surface. But climate change and the Anthropocene thesis raise pressing questions about human interchange with the geological and temporal depths of the earth. Drawing on contemporary earth science and the geophilosophy of Deleuze and Guattari, this article explores how geological strata are emerging as provocations for political issue formation. The first section reviews the emergence – and eventual turn away from – concern with ‘revolutions of the earth’ during the 18th- and 19th-century discovery of ‘geohistory’. The second section looks at the subterranean world both as an object of ‘downward’ looking territorial imperatives and as the ultimate power source of all socio-political life. The third section weighs up the prospects of ‘earth system governance’. The paper concludes with some general thoughts about the possibilities of ‘negotiating strata’ in more generative and judicious ways.

Introductory Article

The functioning of the biosphere and the Earth as a whole is being radically disrupted due to human activities, evident in climate change, toxic pollution and mass species extinction. Financialization and exponential growth in production, consumption and population now threaten our planet’s life-support systems. These profound changes have led Earth System scientists to argue we have now entered a new geological epoch – the Anthropocene. In this introductory article to the Special Issue, we first set out the origins of the Anthropocene and some of the key debates around this concept within the physical and social sciences. We then explore five key organizing narratives that inform current economic, technological, political and cultural understandings of the Anthropocene and link these to the contributions in this Special Issue. We argue that the Anthropocene is the crucial issue for organizational scholars to engage with in order to not only understand on-going anthropogenic problems but also help create alternative forms of organizing based on realistic Earth–human relations.

Qualitative Decision

We introduce and analyse a simple formal thought experiment designed to reflect a qualitative decision dilemma humanity might currently face in view of climate change. In it, each generation can choose between just two options, either setting humanity on a pathway to certain high wellbeing after one generation of suffering, or leaving the next generation in the same state as this one with the same options, but facing a continuous risk of permanent collapse. We analyse this abstract setup regarding the question of what the right choice would be both in a rationality-based framework including optimal control, welfare economics and game theory, and by means of other approaches based on the notions of responsibility, safe operating spaces, and sustainability paradigms. Despite the simplicity of the setup, we find a large diversity and disagreement of assessments both between and within these different approaches.

This chapter introduces the politics of the Earth, which has featured a large and ever-growing range of concerns, such as pollution, wilderness preservation, population growth, depletion of natural resources, climate change, biodiversity loss, and destabilization of the Earth system. It explains how the issues of Earth’s politics are interlaced with a range of questions about human livelihood, social justice, public attitudes, and proper relation to one other and other entities on the planet. It also discusses the consequences of discourses for politics and policies. The chapter clarifies how environmental issues like ecological limits, nature preservation, climate change, biodiversity, rainforest protection, environmental justice, and pollution are interconnected in all kinds of ways. It develops an environmental discourse analysis approach and shows how this approach will be applied in subsequent chapters, beginning with the positioning of environmental discourses in relation to the long dominant of discourse of industrialism.
