This paper arises from the perspective of an educator, community activist, manager and policy maker and argues for a radical change in the methodologies used to teach and share ideas for climate change mitigation and adaption to ‘bend down the curve’ on greenhouse gas emissions. Humanity is destroying the safe operating space for itself in planet Earth’s boundaries framework. Alongside science and technological advancements to mitigate further damage, learning in society needs curiosity, inquiry and an openness to community, planet and Cosmos. This chapter explores how action research can contribute to the development of such learning. The chapter calls for action research to be adopted as a transformational learning methodology, an orientation towards inquiry and as an underpinning methodology across science, technology and policy making.
