evidence: It found that of 7,000 misleading posts describing climate change as "hysteria", "alarmism", a "scam", or other related terms, only 8% were marked as misinformation. [...] The CCDH looked at a sample of posts from the past year which attracted roughly 700,000 likes and shares. Researchers used social media analytics tool Newswhip to search for strings of key words including "climate change", global warming" and, "fraud", "hoax", "cult", "scam", "lie" and so on. [...] The group also identified 113 ads on Facebook with messages like "climate change is a hoax" between January and October 2021 with an estimated spend of between $58,000-$75,000 (about £42,000- 55,000).
