“We systematically investigated the different causes, such as vertical land motion, ice-mass loss, and air pressure, but none of them could sufficiently explain the recent rate.'
“These rapid rates are unprecedented over at least the 20th century and they have been three times higher than the global average over the same period,” says Sönke Dangendorf, lead author and the David and Jane Flowerree Assistant Professor in the Department of River-Coastal Science and Engineering at Tulane.The authors identified the specific causes of the acceleration by analyzing field and satellite measurements going back to 1900.
“Instead, we found that the acceleration is a widespread signal that extends from the coasts of the Gulf of Mexico up to Cape Hatteras in North Carolina and into the North Atlantic Ocean and Caribbean Seas, which is indicative of changes in the ocean’s density and circulation.” This entire region, known as the Subtropical Gyre, has been growing over the last 12 years primarily as a result of altered wind patterns and ongoing warming. Sea levels rise as a result of the requirement for additional space created by warmer water masses.
According to the researchers, the recent acceleration resulted from the unfortunate coincidence of signals related to human-caused and a high in weather-related variability that lasted for several years. They concluded that in the upcoming decades, the rates would probably return to the more reasonable range suggested by climate models.“However, this is no reason to give the all clear,” said Torbjörn Törnqvist, co-author and the Vokes Geology Professor in the Department of Earth and Environmental Sciences at Tulane.
