The relentless storms that hit California from Dec. 27 to Jan. 16 caused extreme flooding and extensive damage, killing at least 22 people. Climate scientists told us it’s too soon to know whether climate change had a role in this particular event, and if so, to what degree.
The warming trend in global temperature continued in 2022, which was the sixth-warmest year on record, according to a recent report from the National Oceanic and Atmospheric Administration. But a viral tweet — using just a small segment of a NOAA graph — wrongly claimed the agency had announced a “global cooling” trend.
An unclear tweet from New York City health officials was meant to caution residents that the latest omicron subvariant, XBB.1.5, might be more likely than previous variants to infect vaccinated or previously infected people. Social media posts misinterpreted the tweet to mean that vaccinated people were at higher risk than unvaccinated people.
Government health agencies disclosed a potential safety concern for strokes in those 65 and older with one of the COVID-19 vaccines, but the agencies haven’t found any causal relationship and the concern was flagged by just one of several monitoring systems. Anti-vaccine campaigners, however, have wrongly claimed the agencies have found a link between the boosters and strokes.
Sports medicine experts say there has been no increase in sudden death or cardiac injury among U.S. athletes since the COVID-19 vaccines became available. Yet anti-vaccine campaigners, comparing unreliable numbers to an unrelated study, have again spread a false narrative about vaccine safety since NFL player Damar Hamlin suffered cardiac arrest.
Buffalo Bills player Damar Hamlin collapsed on the field and suffered a cardiac arrest moments after taking a hit to his chest during a tackle. While it’s not yet known why his heart stopped, some experts say his condition is most likely due to a heart rhythm problem as a result of that impact. Still, people on social media have baselessly speculated that it was caused by a COVID-19 vaccine.
Several European countries have reported an early spike of group A strep infections, mostly among children, including cases of rare but deadly bacterial infections. There is no evidence the increase is being caused by nasal spray flu vaccines, as social media posts baselessly suggest. Flu vaccination may even indirectly prevent strep A.
