This article examines the temporal rhetoric of Extinction Rebellion and Fridays For Future to discuss how the new generation of climate movement organizations offers ideas of an open future that can be acted upon. Research has shown how climate organizations create economic and social disruptions. However, as the article shows, they also create temporal disruptions. Taking theoretical inspiration from critical utopian studies, the article states that the climate activists should be understood as utilizing a disruptive utopian method that aims to disrupt the present and thereby open the future. The method relies on utopias that are relational and open, not static or absolute. Hence, the utopianism employed by these groups is not about closure and perfection, but rather about openness and offering alternatives.
