Governance for Earth system tipping points – A research agenda

Tipping points in the Earth system could be passed within the Paris Agreement's temperature goal range (1.5°C–2°C). Tipping processes are a feature of complex Earth system dynamics that present major governance challenges not addressed by existing global governance institutions. The common governance toolkit is a poor match for dealing with tipping processes, especially non-linear change, and radical intertemporality. To support the development of effective responses to anticipated, rapid state changes in the Earth system, there is an urgent need for new interdisciplinary research programs focused specifically on tipping-point governance. We distinguish two domains of action in a multi-phase framework - prevention and impact governance - and identify key research areas and questions that need to be addressed. These include developing governance principles, identifying actors and institutions that should be involved or need to be created, and determining the appropriate temporal and spatial scales for governance efforts.
