The Climate Action Lab (CAL) is releasing the first version today, September 20, 2019, in solidarity with the week of Climate Strike actions that will be taking place in New York and across the world. This pamphlet emerges from the work of the Climate Action Lab at the Graduate Center, CUNY. It crystallizes a year-long series of workshops during the Fall of 2018 and Spring of 2019 with activists, researchers, and artists intended to reimagine climate politics through the lens of the city as both the frontline impact zone and the potential source of grassroots alternatives informed by the principles of climate justice. Devised in a spirit of militant cooperative research at the juncture between the public university and urban social movements, this pamphlet is not aimed at putting forward a single programmatic plan for the city—hence the question mark at the end of the title, intended to signal an ethos of both critical interrogation and radical imagination.
