Are climate change conspiracy theories widespread across the world, or do we find climate change conspiracy beliefs more so in some countries than in others? This research note explores the prevalence of conspiracy beliefs that identify climate change as a hoax across eight geographically and culturally diverse countries.

Conspiracy theories have transitioned from fringe phenomena to central forces shaping public opinion and political discourse worldwide. Driven by the digital transformation of information, conspiracy beliefs increasingly pose a challenge across the world. Recent research has sought to unravel the psychological, social, and political dimensions of conspiracy beliefs, recognizing their potential to polarize societies, incite political violence, and undermine civic trust.
