“Proponents of research on geoengineering simply keep ignoring the fact that the biosphere is a player (not just a responder) in whatever we do, and its trajectory cannot be predicted. It is a living breathing collection of organisms (mostly microorganisms) that are evolving every second—a ‘self-organizing, complex, adaptive system’ (the strict term). These types of systems have emergent properties that simply cannot be predicted. We all know this! Yet proponents of geoengineering research leave that out of the discussion.”
