The fatalistic belief that climate catastrophe is inevitable and action is pointless, which climate scientists and activists fight as self-fulfilling prophecy.
Extinction Narrative
Some climate activists embraced “we’re already doomed” messaging. Extinction Rebellion’s name implied human extinction was possible. Viral posts claimed civilization would collapse by 2030-2050. Climate scientist Michael Mann warned this “doomism” was new form of climate denial—if we’re doomed anyway, why bother acting?
Psychological Appeal
Doomerism offered perverse comfort—accepting inevitable collapse absolved responsibility for action. It also reflected legitimate despair: IPCC reports worsened, emissions kept rising, governments failed to act. For young people facing climate futures, doomerism felt honest versus false optimism.
Fighting Fatalism
Climate communicators pushed back: we’re not doomed, we’re in crisis with choices ahead. Every 0.1°C matters. Catastrophic warming can be limited even if 1.5°C is exceeded. Giving up guarantees worst outcomes. By 2023, climate discourse balanced urgency with agency—scared but not paralyzed, realistic but not defeated.
