Résiliænces Métamorphoses

The term ‘Anthropocene’ was coined in recognition that human activities have ended the relatively stable environment of the Holocene epoch. However, its widespread adoption across the humanities, arts and sciences has led to diverse and sometimes incompatible definitions. In this Perspective, we argue for a stabilized definition of the Anthropocene epoch to help address contemporary environmental challenges, and explore various applications of the Anthropocene across disciplines. The Anthropocene epoch, with a proposed start point in 1952, underscores that human-driven global-scale environmental disruption differs from earlier human impacts of the Holocene, which did not cause such profound destabilization. This clear distinction enables quantitative and qualitative comparisons between the Holocene and Anthropocene epochs, as already utilized, for instance, within the planetary boundaries framework. As the Anthropocene Earth system transformation is systemic, political responses also need be systemic, rather

I always say that models are not predictions; they are qualitative illustrations of what the future could be. But as the future gets closer to the present, models can start being seen as predictive tools. It is the weather/climate dichotomy, so aptly exploited to confuse matters by politically minded people in the discussion about climate. Right now, we are getting close to the point that we could forecast a collapse in the same way as we can forecast the trajectory of a tropical storm. So, you remember how “The Limits to Growth” generated a long term forecast in 1972. Here it is

Sept des neuf limites préservant nos possibilités d’existence sont franchies, sous les coups de boutoir des activités humaines. De ces limites et des dynamiques de destruction en cours, Dominique Bourg tire cinq leçons générales (démographique, quantitative, qualitative, normative et spirituelle) – leçons qui devraient refonder notre manière d’être au monde, pour autant qu’on veuille encore vivre sur Terre et non sur une planète brûlante, offrant un accueil réduit et malaisé à l’humanité comme aux espèces qui l’accompagnent. Les limites planétaires interrogent nos modes de vie et soulignent la nécessité de restreindre drastiquement notre développement matériel. C’est factuel, sciences à l’appui. Personne ne pourra dire qu’il ne savait pas – pas même nos responsables politiques, car l’indispensable référentiel des limites planétaires est enfin traduit en français.
