A new study carried out by researchers at the University of Arizona points out that people on the Northeast coast of the U.S. should be prepared for short-term sea level events in the near future. This is after it was found that the sea level in this area rose nearly 3.9 inches between 2009 and 2010. The findings have been published in the journal, Nature Communications.
The findings suggest that sea level rises could become a common event during the next century something that may cause flooding’s or storm surge. The sea level rises in the area was an unprecedented event according to Prof, Jianjun Yin, of the University of Arizona as it only happens once in an 850 year period. The researchers carried out studies on tidal levels along the entire east coast both in the U.S and Canada.
Data from studies showed that the period between 2009 and 2010 experienced an extreme sea level rise when the sea level in the North of New York rose 128mm or 5 inches. The increased levels according to researchers is a clear indication that when coastal storms occur there is a high likelihood of a storm surge.
Increase in sea level in the Northeast coast according to the study was as a result of a 30% slowdown in a major ocean current system known as Atlantic meridional overturning circulation AMOC. A slowdown of the AMOC according to the study was contributed by severe winter conditions in Northwestern Europe.
The gradual increase in sea levels around the world is an indication that communities leaving near the areas ought to be prepared for extreme sea-level rise events. Changes in Regional Ocean circulation and even patterns of the wind only goes to suggest that there will be more increases of this nature in the near future.
The Northeast coast of America is an area of fast active ocean currents meaning it remains susceptible to changes in ocean circulation that might result in abrupt sea level rises causing flooding.
