China air quality projections used to promote coronavirus cremation hoax

A popular Facebook post is taking an image out of context to promote a hoax about the cremation of coronavirus victims.

The post, which was published Feb. 15, includes an image that claims to show a "spike in sulfur dioxide emissions just outside Wuhan." The image cites Instagram user @conspiracyplots, who published it the same day.

"Sulfur dioxide is a gas that is released when organic matter, such as human bodies, are burned," reads text underneath the image. "This alarmingly high level of the gas may be a sign of mass cremations of victims of the coronavirus."

The post was flagged as part of Facebook’s efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Facebook.)

According to the World Health Organization, the 2019 coronavirus has infected more than 81,000 people in 37 countries. The vast majority of the 2,761 deaths have occurred in China.

The Chinese government has ordered for the swift cremation of patients who die after contracting the coronavirus. But the Facebook post does not show sulfur dioxide resulting from cremation.

Twitter user @inteldotwav first connected cremations in China with heightened levels of sulfur dioxide near Wuhan. In a Feb. 8 thread, the user posted a screenshot of a map from Windy.com, a website that tracks global wind and weather patterns. It has more than 12,200 retweets.

One of the possible reasons for the influx of sulfur dioxide, @inteldotwav said, is that "dead bodies are being burned on the outskirts of the city." Several tabloids uncritically reported the false claim and later retracted their stories after fact-checkers debunked them.

“The CDC says that little 6 month old babies must get SEVEN doses of the Covid vaccine in order to be considered fully ‘up to date’ on their vaccinations.”

There are a few things wrong with the sulfur dioxide conspiracy theory.

First, Windy.com provides air quality projections — not real-time atmospheric conditions.

Second, China’s National Environmental Monitoring Center has addressed the image in the Facebook post. The state-run Xinhua News Agency reported that environmental officials had recorded sulfur dioxide levels several times lower than what Windy.com showed.

Third, while the gas can be produced by burning organic matter, sulfur dioxide mostly comes from burning coal and oil. And there are several coal power plants and oil refineries near Wuhan.

The Facebook post is inaccurate and ridiculous. We rate it Pants on Fire.
