If understanding global environments, ecologies, geologies, and human systems depends at least in part on access to the materiality of those systems, then these understandings are necessarily affected when the networks and devices we use to access them change. Access to locations, materials, and people has been affected by the global pandemic, war, the effects of anthropogenic climate breakdown, and other changes in supply chain practices and logistics, thereby creating planetary feedback loops. How does planetarity and its composition shift under conditions of planetary change? Which new dynamics do natural and human sciences need to recognize in order to reckon with the reality of these ever-shifting grounds?
