Human-Computer Interaction (HCI) is a means for Information and Communication Technologies to help facing the climate-change challenge. Researchers have conducted work on this way for two decades. They followed the track of progressive change through persuasion for individual consumption reduction. This track is however seriously discussed, what leads the community to retarget coming research. This paper reviews the main criticisms of the controversy that takes place in the community, and considers a possible track to overcome the problems: a radical change through new social practices.
