Creating a trigger event and a moment of the whirlwind — a period in which social movements capture the political spotlight in a country in a major way and shift the terms of public debate — is a rare and important accomplishment. The initial rounds of Extinction Rebellion actions in the U.K. in 2018 and Sunrise’s public breakthrough in the United States the same year, as well as the emergence of Fridays for Future in 2019, each made significant waves. However, since then there have been limited moments in which climate activism has resonated as profoundly and altered public opinion. Movements are now actively trying to experiment and innovate in order to create a new wave of whirlwinds — and their success in figuring this out will be critical for whether social movements can win in the future.
