Abstract

Climate activism has played a crucial role in shaping environmental discourse and policy, yet as the climate crisis intensifies, traditional methods are increasingly viewed as inadequate. This paper applies Granular Interaction Thinking Theory (GITT) to analyze the rise of radical climate activism and its societal implications. GITT posits that large-scale social transformations emerge from the accumulation of micro-level interactions, such as protests, media engagement, and public discourse. As climate activism escalates, some groups adopt disruptive tactics—ranging from nonviolent civil disobedience to direct action and sabotage—to force urgent responses from governments and corporations. The study also examines the cognitive and social mechanisms behind this shift, emphasizing the role of informational entropy-based value formation in shaping activists’ strategies and public perceptions. While radical activism can heighten climate awareness and pressure policymakers, it also entails substantial risks, including public backlash, legal repercussions, and internal fragmentation within the movement. In light of these challenges, we advocate an alternative solidarity approach, emphasizing the strategic dissemination of climate and environmental information to the public, the promotion of eco-surplus culture, and the cultivation of cooperative efforts among governments, businesses, and activists to drive meaningful and sustainable solutions.
