YouTube Still Monetizing Some Climate Change Misinformation Videos Despite Promises, Researchers Find

Researchers identified 100 YouTube videos promoting climate change denial that violate YouTube's policy against monetizing such content but were still running ads.
The 100 videos had over 18 million views combined and featured ads from major companies like Costco and Politico.
Another 100 identified videos with over 55 million views promoted climate misinformation but did not violate YouTube's specific policy.
YouTube removed ads from many identified videos but some with over 71 million views remained monetized.
YouTube says policy debates are okay but removes ads from content that outright denies climate change though researchers found their policies and enforcement lacking.
