Climate misinformation in the media is ‘dead,’ new Alliance for Science study finds

Climate misinformation has virtually ceased to exist in the worldwide mainstream print and online media, according to a new study by the Alliance for Science, which analyzed more than 300,000 climate-related news stories over six months.

“Climate denialism is dead as a news media phenomenon,” said study lead author Mark Lynas at a media event to mark the release of the new findings at the Climate Action Zone, a side event of the ongoing Africa Climate Summit in Nairobi, Kenya on September 5, 2023.

Lynas is an author of several climate books and head of research at the Alliance for Science.

He pointed out that 99.98 percent of analyzed media coverage was consistent with the scientific consensus on the reality and seriousness of human-caused climate change. This figure nearly parallels the 99.6 percent consensus he found as the lead author of a recent comprehensive study of the peer-reviewed literature on climate change.

Relegated to the lunatic fringe

“The consensus is well over 99 percent in both the scientific literature and the world’s media,” Lynas said, adding that “the debate about whether climate change is real is well and truly over and is now almost entirely relegated to the lunatic fringe and, of course, social media. The era of false balance, where you used to have a scientist always balanced with a climate denier in news stories, is over.”

The study analyzed six false climate-skeptic themes on social media to estimate the proportion of climate misinformation in the world’s press. It examined their ‘breakout’ occurrence rates in wide-circulation global news stories.
It found only 59 articles containing unchallenged misinformation on these themes in 321,553 climate-related essays, a misinformation rate of just 0.02 percent.

However, because of the enormous media coverage of climate change, even this tiny 0.02 percent proportion was estimated to reach 4.4 billion.

Most of this misinformation was carried on mainstream outlets like Yahoo! and MSN via PR distribution networks and right-wing and conspiracist media such as Epoch Times.

Only two of the six themes received significant breakout coverage in mainstream news.

‘Greenland is not losing ice’

The first was related to a ‘World Climate Declaration’ supposedly signed by 1,500 scientists, which claims that the current warming may be partly ‘natural,’ that it is ‘far slower than predicted,’ that models are ‘inadequate’ and that CO2 is ‘plant food’ and therefore ‘not a pollutant.’ (All these claims have been debunked, and the signatory list contains almost no actively-publishing climate scientists.)

The second misinformation theme related to the claim that the ongoing climate emergency is ‘fake’ because warming so far has been “mild” and that “life on Earth thrived (and was far greener) when CO2 levels were at least 5X higher than today’s”.

Pro-fossil fuels advocates have promulgated it.

The other four themes, variously claiming that Greenland is not losing ice and that wind turbines are toxic, achieved negligible coverage.

“Our findings are good news for the world leaders currently attending the Africa Climate Summit here in Nairobi,” commented Alliance for Science director Dr Sheila Ochugboju.

“We show that the media conversation on climate change has now clearly moved on from denialist talking points.”

But, she cautioned: “This is only the beginning. Overt climate misinformation may be relegated to the margins, but the power of the fossil fuels lobby means things have shifted from denial to delay. We need rapid action to rescue the 1.5-degree Paris target and to ensure sufficient funding for climate resilience and growth in vulnerable regions like sub-Saharan Africa.”

During the Nairobi climate summit, the Alliance for Science is hosting side events events in a Climate Action Zone focusing on food security, climate resilience and combating anti-science misinformation.
