Considers Earth system tipping points. These are reviewed and assessed across the three major domains of the cryosphere, biosphere and circulation of the oceans and atmosphere. We then consider the interactions and potential cascades of Earth system tipping points, followed by an assessment of early warning signals for Earth system tipping points.
Considers tipping point impacts. First we look at the human impacts of Earth system tipping points, then the potential couplings to negative tipping points in human systems. Next we assess the potential for cascading and compounding systemic risk, before considering the potential for early warning of impact tipping points.
Considers how to govern Earth system tipping points and their associated risks. We look at governance of mitigation, prevention and stabilisation then we focus on governance of impacts, including adaptation, vulnerability and loss and damage. Finally, we assess the need for knowledge generation at the science-policy interface.
Focuses on positive tipping points in technology, the economy and society. It provides a framework for understanding and acting on positive tipping points. We highlight illustrative case studies across energy, food and transport and mobility systems, with a focus on demand-side solutions (which have previously received limited attention).
More inclusive global research needs to be undertaken that reflects on the justice and risk aspects of tipping points. Scientists have an agenda-setting function and a breadth of expertise that will be invaluable in navigating the science-policy interface and solving complex problems like tipping points. Greater diversity in terms of cultural, religious, ethnic, gender, background and discipline of researchers is needed. Place-specific information and experience is often lacking as a lot of research is concentrated in high-income countries. In order to harness relevant positive tipping opportunities, researchers and practitioners need to understand diverse living realities and interact with actors outside of their professional ‘bubbles’ (Bentley et al., 2014). Avoiding diverse harms requires a broad range of experience and expertise, and an acknowledgement of the need for plural approaches not only within academic disciplines, but also of diverse knowledge systems beyond academia Tàbara et al., 2021
By being more mindful about inclusiveness, research can bring about more procedural justice into research through participatory co-design, action research and humility on the part of researchers. Diversity and inclusivity of research teams – within and beyond academia – are needed to help find solutions to tipping points that do not exacerbate existing inequities and inequalities.
