Psychologist Tobias Brosch Analyzes Why Climate Crisis Fails to Mobilize Mass Action

opinion-review · 2026-09-24

Tobias Brosch, a professor of sustainability psychology in Geneva, examines why mass climate protests have dwindled despite worsening environmental data. In an interview with Der Freitag, Brosch argues that abstract targets like the 1.5-degree Celsius limit are psychologically ineffective because they lack immediate, tangible consequences. The UN Environment Programme recently declared the 1.5-degree goal currently unattainable, hoping it might be revisited later. Brosch notes that this alarming news has not triggered widespread public reaction. He suggests that fact-based communication is less effective than other strategies in motivating climate action. The conversation explores the disconnect between escalating climate facts and the absence of a corresponding rebellion, questioning why people who once marched en masse no longer do so. Brosch's research focuses on how communication strategies influence this phenomenon. The interview was published by Der Freitag, with the full article available behind a paywall. No specific art-related content is present; the discussion centers on psychology and climate communication.
