YouTube is making millions of dollars a year from advertising on channels that make false claims about climate change, as content creators employ  new tactics that evade the platform's policies to combat misinformation, according to a report published on Tuesday.

The Center for Countering Digital Hate (CCDH) used artificial intelligence to review transcripts of 12,058 videos  from the past six years on 96 YouTube channels. YouTube is owned by Alphabet Inc., the parent company of Google.

The channels promoted content that undermines the scientific consensus on climate change that human behaviour  contributes to long-term shifts in temperature and weather patterns, the report said.

Shifting argument

CCDH, a non-profit that monitors online hate speech, said its analysis found that climate denial content has shifted away from false claims that global warming is not happening or that it is not caused by greenhouse gases produced from burning fossil fuels. Videos espousing such claims are explicitly banned from generating ad revenue on YouTube, according to Google's policy.

Instead, the report found that 70 per cent of climate denial content on the channels it analyzed last year focused on attacking  climate solutions as unworkable, portraying global warming as harmless or beneficial, or casting climate science and the environmental movement as unreliable. That's up from 35 per cent five years earlier.

"A new front has opened up in this battle," Imran Ahmed, chief executive of CCDH, said on a call with reporters. "The  people that we've been looking at, they've gone from saying climate change isn't happening to now saying, 'Hey, climate  change is happening but there is no hope. There are no solutions.'"

YouTube defends policies

YouTube earns up to $13.4 million a year from ads on the channels included in the analysis, CCDH said. The group said the AI model was crafted to be able to distinguish between reasonable skepticism and false information.

In a statement, YouTube did not comment directly on the report but defended its policies.

"Debate or discussions of climate change topics, including around public policy or research, is allowed," a YouTube  spokesperson said. "However, when content crosses the line to climate change denial, we stop showing ads on those videos."

CCDH called on YouTube to update its policy on climate denial content and said the analysis could assist the  environmental movement to combat false claims about global warming more broadly.
