Sea levels rose as much as 2 feet (60 centimeters) higher than predicted this summer along the U.S. East Coast, surprising scientists who forecast such periodic fluctuations.

The immediate cause of the unexpected rise has now been solved, U.S. officials say in a new report (hint: it wasn't global warming). But the underlying reason remains a mystery.

A new report from NOAA has identified the two major factors behind the high sea levels—a weakened Gulf Stream and steady winds from the northeastern Atlantic.
