New research has found that scientists studying sea-level rise have been using methods that underestimate how high the water already is. One result is that hundreds of millions more people worldwide are already living dangerously close to the rising ocean than Western scientists had previously estimated.

The new study, published Wednesday in the journal Nature, has found that the vast majority of scientific studies have made this mistake. Coastal sea levels are, on average, eight inches to a foot higher than many maps and models of the world’s coastlines indicate, the research found.
