Department of Radiation Sciences, Umeå University invited me to be the moderator of a debate between students at the course Sustainable Development and Environmental Radiology.  The students were divided in groups debating wether geoengineering is necessary for managing climate change or if other measures are prefered. My views are similar to those formulated by the ETC-group who have a very critical view on geoengineering of climate change. Basically – it is unacceptable.
