From Farm to Planet: The InSEEDS World-Earth Model for Simulating Transitions to Regenerative Agriculture Open
Industrialised agriculture and its externalisation of environmental costs have contributed to accelerating ecological degradation and the transgression of planetary boundaries. Vice versa, agriculture is increasingly affected by ecological…

Culture Mediates Climate Opinion Change: A System Dynamics Model of Risk Perception, Polarization, and Policy Effectiveness Open
Despite the growing impacts of climate change worldwide, achieving consensus on climate action remains a challenge partly because of heterogeneity in perceptions of climate risks within and across countries. Lack of consensus has hindered …

Social norms and groups structure safe operating spaces in renewable resource use in a social–ecological multi-layer network model Open
Social norms are a key socio-cultural driver of human behaviour and have been identified as a central process in potential social tipping dynamics. They play a central role in governance and thus represent a possible intervention point for…

Policy, Risk, and Norms Shape Collective Behaviors Worldwide Open
Societal responses to environmental change vary widely, even under comparable shocks, reflecting differences in both policy measures and public reactions shaped by cultural and socioeconomic contexts. We examine mask-wearing dynamics acros…

A method to identify positive tipping points to accelerate low-carbon transitions and actions to trigger them Open
Meeting the Paris Agreement to limit global warming to “well below 2 °C” requires a radical acceleration of action, as the global economy is decarbonising at least five times too slowly. Tipping points, where low-carbon transitions become …

Beyond tipping points: risks, equity, and the ethics of intervention Open
Earth system tipping points pose existential threats to current and future generations, both human and non-human, with those least responsible for causing them facing the greatest risks. “Positive” social tipping points (that we shorten to…

How publics in small-island states view climate change and international responses to it. Open
Climate change caused by carbon pollution from the world's largest economies poses an existential threat to small-island states and territories this century. These places bear virtually no responsibility for climate change but will face se…

Predicting Climate Policy Support with Large Language Models: Assessing Accuracy and Bias in AI-Simulated Policy Support Open
Understanding public support for climate policy is essential for designing effective interventions, yet traditional surveys are often constrained by cost, scope, and temporal resolution. Two studies assess the extent to which large languag…

A meta-analysis of the real-world impact of sustainability labeling on consumer choices Open
Sustainability labeling aims to encourage consumers toward environmentally friendly choices, yet its effectiveness remains uncertain. In this pre-registered meta-analysis of 49 studies (n = 150,221 participants), we assess the impact of su…

Validating the Climate Policy Support Scale in 63 countries and examining responses across political divides Open
We examined data from 59,508 participants across 63 countries to construct a measure of climate policy support and document associations with political orientation across the resulting scale. Preregistered analyses identified a three-facto…

Investigating transitions to regenerative agriculture using the InSEEDS World-Earth model – foundations, first results, and research directions Open
Worldwide, developments towards highly industrialized, conventional agriculture systems have led to ecological deterioration, as well as societal problems. On the ecological side, many Planetary Boundary transgressions can - in substantial…

 Longitudinal Evidence on the Mixed Effects of Hurricane Experience on Behaviors and Policy Preferences Open
Extreme weather events are increasing in frequency and severity due to climate change. This has prompted some scholars to speculate that these increasingly severe and frequent direct experiences with the impacts of climate change might cat…

Targeted incentives for social tipping in heterogeneous networked populations Open
Many societal challenges, such as climate change or disease outbreaks, require coordinated behavioral changes. For many behaviors, the tendency of individuals to adhere to social norms can reinforce the status quo. However, these same soci…

Addressing climate change with behavioral science: A global intervention tournament in 63 countries Open
Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced i…

Negative social tipping dynamics resulting from and reinforcing Earth system destabilization Open
In recent years, research on normatively positive social tipping dynamics in response to the climate crisis has produced invaluable insights. In contrast, relatively little attention has been given to the potentially negative social tippin…

Anticonformists catalyze societal transitions and facilitate the expression of evolving preferences Open
The world is grappling with emerging, urgent, large-scale problems, such as climate change, pollution, biodiversity loss, and pandemics, which demand immediate and coordinated action. Social processes like conformity and social norms can e…

Fair group decisions via non-deterministic proportional consensus Open
Are there group decision methods which (i) give everyone, including minorities, an equal share of effective decision power even when voters act strategically, (ii) promote consensus and equality, rather than polarization and inequality, an…

Positive Tipping Points in the Food Systems: the Role of Scales Open
The global food system is at a critical inflection point with rising awareness of the need for change and progress on several fronts, pertaining both human health and the environment. One of the ten critical transitions envisioned by the F…
