Fact-check: Multiple recent X posts from March 4-5, 2026, including by AP science writer Seth Borenstein, share the Nature study revealing that 90% of coastal hazard studies underestimated baseline sea levels by about 1 foot due to methodological errors, putting 77-132 million more people at risk from sea level rise. This matches the Africanews article's claims exactly, confirmed by browsing the page and PBS coverage of the same study. No contradictions found in real-time reporting.

Sea level rise threatens tens of millions more than estimated

Researchers have discovered that rising sea levels pose a threat to tens of millions more people than previously thought, as most scientific studies have used incorrect baseline data for coastal water heights, Africanews reports. The new findings suggest the true impact of climate change on coastal communities is significantly more severe than earlier assessments.
