The Global Tipping Points Report is a peer-reviewed assessment of the threats and opportunities of negative and positive tipping points in the Earth System and in society.
Tipping points are points beyond which changes can be locked in (for example, the irreversible collapse of an ice sheet or the rapid transition to electric vehicles). They occur when change in a system becomes self-sustaining once pushed beyond a threshold, leading to a substantial and often irreversible shift in the system’s state, even if the initial driver is removed.
The report is in four sections: Earth system tipping points, Impacts, Governance, and Positive tipping points in technology / economy / society.
