This in-depth article discusses large-scale 'technical fixes' proposed for offsetting global warming, such as fertilisation of ocean algae, reflection of sunlight with stratospheric dust, or pumping liquid CO2 into the deep oceans. The paper considers the possible impact both on climatic feedback processes, and also on climate science and climate politics. It concludes by asking whether it is wise to continue such research.
