Polar bear blogs reveal dangerous gap between climate change facts and opinions

climate change discussions on social media are very influential. A new study in BioScience shows that when it comes to iconic topics such as polar bears and retreating sea ice, climate blogs fall into two distinct camps with little or no overlap between deniers and the available scientific facts. The study's first author, NIOO-KNAW researcher Jeff Harvey says, "It's time for scientists to counter the misinformation and engage directly with the public far more."

Polar bears and retreating sea ice have become iconic symbols of the polarised debate. By focusing on these subjects, deniers of human-caused global warming cast doubt among the public about the entire body of climate change knowledge. But a new study of the underlying science used in the debate could well melt down the trustworthiness of these deniers on .

"We found a major gap between the facts from scientific literature and the science-based blogs on the one hand, and the opinions aired in climate change-denying blogs on the other," says Harvey. "It's a very dangerous gap, as these blogs are read by millions."

The researchers analysed 90 climate blogs in total, alongside 92 scientific papers on the subject. Although 45 'denier blogs' claim to be based on science, they failed to overlap with the peer-reviewed evidence in the papers. Instead, they relied mostly on other denier blogs. And 80 percent relied on one in particular, whose author, says Harvey, "had neither conducted any original research nor published any articles in the peer-reviewed literature on ."

By contrast, 45 truly science-based blogs do match the evidence in the scientific papers. And there's not much middle ground.

The team that studied the blogs was international and multidisciplinary, including ecologists, polar bear researchers, scientists, science communicators and psychologists of various ages from six countries. Among the authors are well-known scientists such as Steven Amstrup from Polar Bears International, Eric Post from the University of California, Davis, and Michael Mann from Pennsylvania State University.

Harvey says, "Scientists, climb down from your desk and start to counter the misinformation on social media directly—and via the traditional media, as well. Engage with the public via the blogosphere or citizen science, for example. And very importantly, adjust your focus to what is clear instead of all the uncertain things still to be studied."

If the misinformation is successfully countered, the debate may be 'depolarised' while polar bears and other arctic wildlife still have a future to look forward to.
