Introduction
Enhanced rock weathering (ERW), as a negative emissions technology for climate change mitigation, has received far more public, governmental, and academic attention (according to the authors’ account of engagement with such actors) in the past year than in the many years since its first mention in the literature. The term ERW was conceived by Beerling (2017), but the field of research referred to as “enhanced weathering” (EW) can see
its origins, by this name, at least as far back as the works of Power and Southam (2005) and Lenton and Britton (2006). This opinion piece provides learnings and thoughts from the GeoRewind group at the University of Guelph (Canada) on what we have defined as “pathways,” “roundabouts,” “roadblocks,” and “shortcuts” to the safe and sustainable deployment of ERW in Agriculture.
