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.

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.

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.

If the Anthropocene is a rupture in planetary history, what does it mean for international environmental law? When the Earth System crosses irreversible tipping points and begins a forceful, nonlinear transformation into a hostile state which I call the ruptured Anthropocene, the concept of protecting the global environment from humans would lose its meaning. Not only the dichotomy between humans and nature becomes irrelevant, but the environment itself will no longer exist as an object for protection. I argue that, for international environmental law to stay relevant in the ruptured Anthropocene, it needs to shift away from its traditional focus on restoring the planetary past, and instead play an active role in the making of planetary futures. Its new purpose will need to be active planetary stewardship, whereby humans add self-awareness for deliberate self-regulation of the Earth System. Such an attempt at ‘taming’ the so-called Gaia 2.0 will, however, create winners and losers, and the new form of law will have to address fundamental questions of justice on a planetary scale. Building on the concept of earth system law emerging in the earth system governance literature, I draw the contours of international environmental law 2.0 for the ruptured Anthropocene and discuss the challenges of instituting active planetary stewardship.
