This article examines how the discourse of the new generation of environmental youth movements highlights time and temporality in order to explain the possibilities of change that the movements offer. This is done by analyzing three influential and transnational youth climate movements—Earth Uprising, Extinction Rebellion, and Fridays For Future—in relation to three influential diagnoses of the current political condition: postpolitics, populism, and postapocalypse. The article argues that the movements should be understood as mobilizing through negative utopian energies. Using theoretical inspiration from Ernst Bloch, the article states that the discourse should be read as containing acts of hope and utopian impulses that reach forward toward a new beginning of a future possible. The article shows how the movements challenge the diagnoses of populism and postpolitics by their constant critique of capitalism, by reinstalling the people as heterogenous political subjects, and by representing a new temporality. Moreover, the article shows how the mainstream climate discourse contains two temporal narratives that run parallel to each other: one that can be thought of as a vernacular eschatology and one that is seemingly postapocalyptic. However, the article argues that both narratives provide visions of a better future to come, and by using the notion of anticipation, the article states that even the postapocalyptic narrative can be mobilizing. Thus, the environmental youth movements offer a new kind of discourse, one that is non-postpolitical, nonpopulist, and non-postapocalyptic.
