СКАЧАТЬ as well as to the conditions in which scientific knowledge is produced, to the structuring of a globalized intellectual climate that weighs heavily on the practice of research (Castree et al. 2014), and to the place of the environmental question within globalized societies (Smith 2010). These two bundles of elements, namely the physical reality of unprecedented consequences of human–environment interactions, on the one hand, and the social configurations that accompany them, on the other hand, constitute the Anthropocene moment. The latter is of interest to the reflections gathered in this work on risk assessment and risk management.

      I.2.2. From controversies on the boundary…

      I.2.2.1. The steam engine, the Industrial Revolution and the Great Acceleration

      Proposing the Anthropocene as a new geological epoch requires compliance with the rules of the International Commission on Stratigraphy, the body within the International Union of Geological Sciences that oversees the standardization of a geological time scale. Designating the boundaries of a geological epoch requires two conditions. It is necessary to be able to locate the traces of a global event left in stratigraphic materials (rocks, ice, sediments) and to associate them with other stratigraphic markers indicating changes in the whole earth system. Duly localized traces constitute a “golden spike”4.

      A daunting task lies ahead for scientists and engineers to guide society towards environmentally sustainable management during the era of the Anthropocene. This will require appropriate human behaviour at all scales, and may well involve internationally accepted, large-scale geo-engineering projects, for instance to “optimize” climate. (Crutzen 2002, p. 23)

      Despite the confidence displayed, evidence is lacking to close the stratigraphic debate on the Anthropocene. Above all, underlying ways of seeing the world clash across such categorization, underscoring the interest of axiological controversies in addition to metrological ones:

      Care is needed to ensure that the dominant culture of today’s scientists does not subconsciously influence the assessment of stratigraphic evidence. (Lewis and Maslin 2015, p. 173)

      I.2.2.2. A range of possible hypotheses

      Geological time is marked by changes in the state of the Earth. Between the end of the Pleistocene (11,700 years ago) and the 1960s, several events are strong candidates as anthropogenic signatures of geologic epoch change. Lewis and Maslin (2015) explore several hypotheses and select two.

      The great fires associated with the Pleistocene mass extinctions are discarded, their traces not being explicitly global enough. The stratigraphic evidence of the beginnings of agriculture and the upheavals of the Neolithic are not considered sufficiently synchronous. The process of industrialization and then the industrial revolution bequeath diverse and temporally dispersed markers. On the other hand, 1610 and 1964 are favored by authors as potential starting points of the Anthropocene.

      Each hypothesis reflects an image of societies and their relationship to the environment. The date of 1610 emphasizes the domination and exploitation of resources. The 1964 date points to the concord of an international governance capable of banishing – or at least reducing significantly – the use of nuclear weapons. The fact remains that there is no consensus on the stratigraphic evidence and, above all, that it is only a matter of conforming to the requirements of geology. As such, the axiological controversies surrounding the Anthropocene carry more meaning – and are of greater interest – to the social sciences than the debates on the stratigraphic classification that presides over its identification from the Earth sciences.

      I.2.3. … to the strengthening of meta-narratives

      As a result of the disciplinary divisions, the truth of geology is not the same as that of the social sciences. Framing effects are at work here. Under cover of the authority of the discourses produced by legitimate sciences, we can convey ways of seeing the world. It is the role of the social sciences to identify the meanings produced, to identify the sources of the arguments on which they are based, as well as the interests, the expectations or the benefits linked to social positions. Numerous works contribute to exploring the social scope of the controversies surrounding the Anthropocene (Lorimer 2017), to making explicit the images of the world conveyed (Bonneuil 2015), and even to considering the agenda of autonomous research on the subject (Lövbrand et al. 2015; Davis and Todd 2017).

      In this respect, the identification of major narratives conveyed by the Anthropocene is instructive of the possible contributions of social sciences (Bonneuil 2015):

       – Earth sciences introduce a naturalistic narrative, which separates man and nature, by giving science and technology the means to sound the alarm and to find solutions. The advent of a global and homogeneous environmental conscience justifies that problems and solutions draw from the same source (Crutzen and Stroemer 2000);

       – the postnature narrative does not recognize the modern separation between nature and culture. It comes into play to the extent that it recognizes that the outcome of actions is beyond the control of the will alone. We humans “become geology” (Latour 2015) and the emerging reflexive subject must acknowledge this (Beck 1992). The great divide between nature and culture blurs to define a common hybrid, of humans and non-humans, able to identify the environmental question as superior and ultimate;

       – the ecocatastrophic narrative has been a recent bestseller (Servigne and Stevens 2015), while at the same time reviving the apocalyptic reflections of the post-Second World War era (Anders 1995) or those dealing with the autonomy of technology (Mumford 1950). From the limits of the planet to the prospect of collapse, it is impossible for societies to think of themselves as being alone in the maneuver. The capacity for action is shifted toward a kind of ecomodernism that would allow us to act in a more relational way on/with the environment (of which societies are part);

       – the ecomarxist narrative applies the grid of reading historical materialist antagonisms (Keucheyan 2014; Moore 2017a), opposing classes and interests. The Anthropocene moment is the contemporary theater of the contradictions of capitalism, especially those that confront it with the depletion of resources in a finite world.
