WASHINGTON, DC – Unforeseen, short-term increases in sea level caused by strong winds, pressure changes and fluctuating ocean currents can cause more damage to beaches on the East Coast over the course of a year than a powerful hurricane making landfall, according to a new study. The new research suggests that these sea-level anomalies could be more of a threat to coastal homes and businesses than previously thought, and could become higher and more frequent as a result of climate change.
The new study found that unexpected increases in water level of a few centimeters (inches) to a half a meter (almost two feet) above the predicted high tide correlated with the loss of more than half a meter (almost two feet) of beach height on a North Carolina barrier island during 2009 and 2010. This was similar to the amount of erosion in 2010 to 2011 when Hurricane Irene – a category one hurricane with a storm surge of two meters (almost seven feet) high – swept away about a third of a meter (just over a foot) of sediment from the same beaches, according to a new study published last week in Geophysical Research Letters, a journal of the American Geophysical Union.
You can read the rest here. Basically this looks like a lame attempt to make king tides look like they are enhanced significantly by sea level, and make sea level an elevated issue so they can argue with North Carolina to re-enact the sea level laws they gutted this in 2012.
And it is a single island. It reminds me of the wailing over this sand bar that disappeared.
