Complexity as a Catalyst: Enabling Global Environmental Change in a Deeply Divided World

How complexity thinking can inform adaptive climate governance and diplomacy in an era of division and interdependence.

Meeting internationally agreed climate goals requires dramatically faster emissions reductions and transformative adaptation across sectors. Yet current climate policy and governance frameworks often assume an economy in equilibrium – where decarbonization is costly, diplomacy is a zero-sum game, and national interests are fixed. In a world that is increasingly divided and contested, these assumptions limit effective action.

This 海角社区-CPR discussion paper explores how complexity science offers a new lens for global environmental governance. Complexity thinking views systems as dynamic, interconnected, and adaptive, emphasizing feedback loops, non-linearity, emergence, and co-evolution. Applied to climate change, it suggests that progress can emerge from reinforcing feedbacks, tipping points, and adaptive governance rather than from top-down consensus.

By integrating these insights into national policy, diplomacy, and institutional design, complexity can act as a catalyst – guiding systems to self-organize toward zero-emission pathways and more resilient forms of cooperation.
