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.
Usually, predicting seasonal tides and sea levels is a pretty cut-and-dried process, governed by the known movements and gravitational influences of astronomical bodies like the moon, said Rich Edwing, deputy director for the Center for Operational Oceanographic Products and Services at the U.S. National Oceanic and Atmospheric Administration (NOAA).
But NOAA’s phones began ringing this summer when East Coast residents reported higher than predicted water levels, much like those associated with short-term weather events like tropical storms. But these high seas persisted for weeks, throughout June and July.
The startling rise caused only minor coastal flooding—but major head scratching among scientists.
No, no. It wouldn’t be global warming. We don’t know what could melt ice, create more water and raise the ocean levels, but it certainly wouldn’t be heat. Heat never melts ice. That is a myth perpetuated by environmental wackos. Ignore this:
As five European foreign ministers meet in Copenhagen to prepare for an agreement to succeed the Kyoto Protocol, scientists in Greenland are warning about accelerated glacier melts. Several years ago, scientists reported that the Helheim Glacier, suddenly and without warning, had begun accelerating, spitting icebergs ever faster into the ocean off southeastern Greenland.
In just two years, it doubled its speed. Other Greenland glaciers made similar accelerations. – natgeo
