OCEAN SCIENCE:
Coral Clues to Rapid Sea-Level Change

Gideon M. Henderson

Earth's climate can change substantially on time scales of 1000 years or so, but given the time it takes for an ice sheet to grow or melt, it has been unclear whether continental ice sheets-and hence global sea levels-mirror these rapid changes. In his Perspective, Henderson discusses the report by Thompson and Goldstein, who have used a new correction method to date coral samples that are up to 250,000 years old. The corals can be used to deduce past sea levels. The resulting sea-level record shows that sea levels have varied on millennial time scales even during times of high sea level and relative climate stability.
