A team of researchers reported Wednesday that the ocean did not rise quite as much as previously believed in the 20th century. They proposed a seemingly tiny adjustment that could make a big difference in scientific understanding of the looming problem of sea-level rise.

Instead of rising about six inches over the course of the 20th century, as previous research suggested, the sea actually rose by approximately five inches, the team from Harvard and Rutgers Universities found. The difference turns out to be an immense amount of water: on the order of two quadrillion gallons, or enough to fill three billion Olympic-size swimming pools.

If the findings stand up to scrutiny by other scientists, they could help resolve a longstanding conundrum in climate research. For years, when experts added up their best measurements of melt water from land ice and of other factors causing the sea to rise, the numbers fell a bit short of the rise that had been recorded at harbors around the world...
