Summary

For 20 years, Exxon researchers have touted geologic benchmarks measured on the continental margins as evidence of changes in global sea level. But academic geologists have been skeptical, for much of the supporting data was proprietary. New data from ocean cores suggest that the Exxon geologists were right after all, but the mechanism behind the most ancient sea-level swings remains a mystery.
