The arrival of the Anthropocene entails an evolutionary tipping point that challenges basic precepts of political theory and modern science. Within this paper, emerging scholarship in political science, science and technology studies, and sustainability science are brought together to sketch out an approach for crafting more just and sustainable pathways in response to the crossing of critical thresholds in the Earth system. Accomplishing this task requires responding to the emerging reality of possibility, irreversibility, entanglement, and novelty that the Anthropocene and tipping points entail. I argue that grounding political projects in recognition of the unfolding and unpredictable terrain tipping points present allows for the opening of novel pathways toward a still possible just and sustainable planet.

There is mounting evidence that some parts of the Earth system may be at risk of abrupt and potentially irreversible changes, driven by the cumulative impact of incremental global warming. Such a non-linear transition could be triggered if a critical threshold in global temperature – a “tipping point” – is crossed, when a small change could push a system into a completely new state, with potentially catastrophic impacts. In this technical briefing, we will first define tipping points and tipping elements, then explore several tipping elements in more detail and discuss the questions of abruptness, irreversibility, timescales and uncertainties for each of them. We also investigate the possibility of developing early warning systems for tipping points, and the risk of cascades of interacting tipping points, where one tipping point could trigger another.

Abstract The Earth system and the human system are intrinsically linked. Anthropogenic greenhouse gas emissions have led to the climate crisis, which is causing unprecedented extreme events and could trigger Earth system tipping elements. Physical and social forces can lead to tipping points and cascading effects via feedbacks and telecoupling, but the current generation of climate-economy models do not generally take account of these interactions and feedbacks. Here, we show the importance of the interplay between human societies and Earth systems in creating tipping points and cascading effects and the way they in turn affect sustainability and security. The lack of modeling of these links can lead to an underestimation of climate and societal risks as well as how societal tipping points can be harnessed to moderate physical impacts. This calls for the systematic development of models for a better integration and understanding of Earth and human systems at different spatial and temporal scales, specifically those that enable decision-making to reduce the likelihood of crossing local or global tipping points.

Political geology is concerned with the relationship between geological process, matter, and politics. It is a relatively recent neologism adopted by geographers and includes scholarship from a number of disciplines adjacent to geography, including anthropology, history of science, science and technology studies, and religious studies. The emergence of the Anthropocene no doubt played a role in raising geographers’ interest in the politicization of geology and geological knowledge. Much work in the field has begun to depart from the lens of Anthropocene studies and venture into new intellectual territory. Political geology seeks to understand geological knowledge as a tradition with histories and geographies. It studies the history of the geological sciences across world cultures and has an expanded conception of geological knowledge (and the sciences) beyond a focus on Euro-America. It is building a cosmopolitan understanding of the geological sciences. Geological knowledge is not taken for granted to speak for the earth system but is placed in its cultural, technological, and political context. At the same time, political geologists are concerned with the vibrant, lively materiality of geology. They are interested in Earth’s capacity to act upon politics and create political cultures. A renewed attention to the agency of geology has resulted in a number of papers that stress the ‘geo’ in geopolitics—the grounded, material dimension that situates all and any politics. There has therefore been an uptick in scholarship on verticality, depth, and resource extraction that foregrounds the material agency of geological process. This has been further brought together with consideration of the multiple knowledge traditions that claim to know and represent geological material. The conventional distinctions between geology and spirituality, geological sciences and religion, organic and inorganic, have been questioned. Alternative modes of writing about geology and the sciences are being explored through performance, fiction, sculpture, and poetry. Political geological scholarship thus brings together a number of discussions about the intersections among knowledge, Earth, power and governance. What follows is a broad introduction and survey of the key formative works of political geology, histories of geological knowledge, theoretical preoccupations, and sites of interest to political geologists. The theory and sites sections are ordered alphabetically.

Modern science and modern scientific methods, with all their splendor of achievement, have led to an ethical vacuum, a religious vacuum, and a philosophical vacuum—so it has been said. For they have offered little or nothing to distinguish between good and evil, right and wrong, justice and injustice. All social sciences are involved in this calamity, but none has been so deeply affected as political science, which had to face the new creeds of Communism, Fascism, and Nazism as political phenomena of tremendous power. They settled down in the area abandoned by science, taking full advantage of the fact that, scientifically speaking, there was a vacuum.No political theorist can honestly avoid the issue, and certainly every scholar worthy of the name gives it serious thought. While each may publish his own ideas freely, there is one thing which we cannot do individually, but which we may do collectively—take stock of the various opinions that prevail among us, and clarify their meaning by question and answer. This the members of a round-table tried to do at the last meeting of the American Political Science Association, in two sessions held jointly with the Research Panel on Political Theory, represented by its chairman, Francis G. Wilson of the University of Illinois.

<p>It has been argued that several components of the Earth system may destabilise in response to gradually changing forcing such as rising atmospheric greenhouse gas concentrations and temperatures. Key examples of potentially unstable parts of the Earth system include the polar ice sheets and sea ice cover, the Atlantic Meridional Overturning Circulation, as well as tropical rainforests and monsoon systems. There are reasons to believe that the leading dynamical modes of these subsystems may essentially mimic bifurcations in low-order random dynamical systems. The stability loss on the way to critical transitions associated with such bifurcations typically leaves characteristic imprints in the statistics of time series encoding the dynamics of the system in question, which can hence serve as a proxy to assess the stability of the system. Here, we present recent advances in detecting stability loss along these lines and investigate proxy reconstructions and observations of several of the Earth system components that have been proposed to be at risk of destabilisation. We discuss the control parameters relevant for the different Earth system components and report on the posterior distributions of the critical thresholds, beyond which stability would be lost. </p>
