What is indigenous good sense on climate change? This chapter opens up a dialogue between the substance of indigenous knowledge, on the one hand, and the Gramscian concept of good sense vis-à-vis global warming, on the other. Good sense as practical knowledge is primarily relevant for local adaptation to climate change. Good sense as a “conception of necessity” concerns mitigation, and it has both a scientific and moral aspect to it. The latter is more inherent to indigenous knowledges than the former. The “system change – not climate change” message is a forceful way of expressing good sense as an interest in truth. The author sees climate justice as the singular most important example of good sense in motion and the emergent themes of “anti- extractivism” and “yes to more public goods” are considered vital for the building of a broader popular climate struggle. The strategic and practical task is to combine aspects of indigenous good sense with the good sense of other groups, like the school strikers or the trade unions for energy democracy. All the dimensions of good sense need to be tapped and developed into the most efficient collective climate action project possible, if indigenous planetary consciousness is to matter and supersede the current hegemonic order.
