''Since IPCC Fifth Assessment Report, many new sources of knowledge have been employed to provide better understanding of climate change risks, impacts, vulnerability and also societal responses through adaptation, mitigation and sustainable development. This new, more integrative assessment focuses more on risk and solutions, social justice, different forms of knowledge including IK and LK, the role of transformation and the urgency of fast climate actions.''

The IPCC Sixth Assessment Report (AR6) has played a prominent role in science–policy–society interactions on the climate issue since 1988 and has advanced in interdisciplinary climate change assessment since AR5. Many new sources of knowledge have been employed to provide better understanding of climate change risks, impacts, vulnerability and also societal responses through adaptation, mitigation and sustainable development.

This AR6 assessment focuses more on risk and solutions. The risk framing for the first time spans all three Working Groups. It includes risks from the responses to climate change, considers dynamic and cascading consequences, describes with more geographic detail risks to people and ecosystems, and assesses such risks over a range of scenarios. The solutions framing encompasses the interconnections among climate responses, sustainable development and transformation, and the implications for governance across scales within the public and private sectors. The assessment therefore includes climate-related decision making and risk management, climate resilient development pathways, implementation and evaluation of adaptation, and also limits to adaptation and loss and damage.

The AR6 emphasises the emergent issue on social justice and different forms of knowledge. As climate change impacts and responses are implemented, there is heightened awareness of the ways that climate responses interact with issues of justice and social progress. In this report, there is expanded attention on inequity in climate vulnerability and responses, the role of power and participation in processes of implementation, unequal and differential impacts, and climate justice. The historic focus on scientific literature is also accompanied by increased consideration and incorporation of Indigenous knowledge and local knowledge and associated scholars.

The AR6 has a more extensive focus on the role of transformation and the urgency of fast climate actions in meeting societal goals. This report assesses extensive literatures with an increasing diversity of topics and geographical areas with more sectoral and regional details. The literature also increasingly evaluates the lived experiences of climate change—the physical changes underway, the impacts for people and ecosystems, the perceptions of the risks, and adaptation and mitigation responses planned and implemented.

The assessment in AR6 is more integrative across multiple disciplines and combines experts across Working Groups, chapters, papers and disciplines, such as natural and social sciences, medical and health sciences, engineering, humanities, law and business administration. The emphasis on knowledge for action has also included the role of public communication, stories and narratives within assessment and associated outreach.
