FactCheck.org’s SciCheck feature focuses exclusively on false and misleading scientific claims that are made by partisans to influence public policy. It was launched in January 2015 with a grant from the Stanton Foundation. The foundation was founded by the late Frank Stanton, president of CBS for 25 years, from 1946 to 1971.
Numerous social media posts falsely suggest that because Clorox and Lysol products list “Human Coronavirus” on their bottles, the new coronavirus driving the outbreak in China was already known. It wasn’t. There are many human coronaviruses, and these products were tested against a strain that causes the common cold.
An outbreak of viral pneumonia that began in the central Chinese city of Wuhan at the end of 2019 has now sickened thousands, and led to more than 100 deaths. Here, we answer some key questions about what is known so far about the outbreak and the virus.
Multiple social media posts are spreading a bogus conspiracy theory about the deadly Wuhan virus. The posts falsely claim that the virus has been patented and a vaccine is already available. That’s not true; the patents the posts refer to pertain to different viruses.
The Trump administration announced a new policy that will soon forbid the sale of some, but not all, flavored vapes. We explain the new policy and review the scientific evidence on whether e-cigarettes are likely to have a positive or negative impact on public health.
President Donald Trump boasted of the lowest cancer death rate on record, and implied that his administration was responsible for the achievement. While he’s right about the statistic, the improved death rate is the result of decades-long efforts on cancer prevention, detection and treatment.
Democratic presidential candidate and former Vice President Joe Biden claimed without evidence that “more people are coming home from Iraq with brain cancer” than “any other war,” and blamed burn pits for the purported increase. But existing statistics do not bear that out, and the evidence on the cancer risk of burn pits is inconclusive.
President Donald Trump mocked concerns about global warming, saying that oceans would rise just “[o]ne-eighth of an inch within the next 250 years.” Although he may have been joking, his figure is many times lower than scientific estimates.
In the last Democratic debate, Sen. Bernie Sanders said that the United Nations is projecting “hundreds of millions of climate refugees” in the “years to come” as a result of climate change. The U.N., however, doesn’t currently endorse a particular estimate.
For the second year in a row, President Donald Trump inaccurately attributed California’s rash of wildfires to poor forest management. He also falsely said other states don’t have “close to the level of burn” as California.
Sen. Bernie Sanders has said “scientists tell us” that it’s possible to go carbon neutral without relying on nuclear power. Fellow Democratic presidential candidate Sen. Cory Booker, who backs the use of some nuclear energy, has said the data is on his side. Who’s right? Both have a point, but neither is telling the full story.
