Large-scale technological interventions to “fix” the climate crisis are moving up on the political agenda. Some climate scientists are now proposing geoengineering interventions on land to halt global warming – most prominently BECCS (Bio-Energy with Carbon Capture and Storage), which combines two controversial technologies: bioenergy and CCS. These schemes to manipulate our ecosystems and global natural processes come with great risks and uncertainties, as well as with foreseeable adverse impacts on land ecosystems and human communities depending on them.
Part I of “A technofix for the climate?” presents some of the marine geoengineering approaches with a focus on their risks, negative impacts and potential side-effects, as well as on the question of governance of these technologies.
