And the Beeb: https://www.bbc.com/news/science-environment-68684244 links to the article: https://www.nature.com/articles/s41586-024-07170-0 which appears to be Springer Open Access for reading. The researcher is Agnew from Scripps UCSD, and thinks a negative leap second is imminent, an unprecedented problem, and a likely disaster, whereas a former USNO rep says it is less likely.
