Sea Level Rise Accelerates In Southeast US - report

The rate of sea level rise in southeastern America has accelerated in recent years, according to a report by Amy White published July 11 in Inside Climate News.

the news could surprise idiot climate deniers who will go out of their way to confect spurious evidence denying sea level rise unaware that sea level rise isn't uniform around the globe.

Sea levels rise in different places at different rates, science has shown.

below are excerpts from the Inside Climate News report.

INSIDE CLIMATE NEWS:

"Across the American South, tides are rising at accelerating rates that are among the most extreme on Earth, constituting a surge that has startled scientists such as Jeff Chanton, professor in the Department of Earth, Ocean and Atmospheric Science at Florida State University.

""It’s pretty shocking,” he said. “You would think it would increase gradually, it would be a gradual thing. But this is like a major shift.”

"Worldwide sea levels have climbed since 1900 by some 1.5 millimeters a year, a pace that is unprecedented in at least 3,000 years and generally attributable to melting ice sheets and glaciers and also the expansion of the oceans as their temperatures warm.

"Since the middle of the 20th century the rate has gained speed, exceeding 3 millimeters a year since 1992.

"In the South the pace has quickened further, jumping from about 1.7 millimeters a year at the turn of the 20th century to at least 8.4 millimeters by 2021, according to a 2023 study published in Nature Communications based on tidal gauge records from throughout the region.

"In Pensacola, a beachy community on the western side of the Florida Panhandle, the rate soared to roughly 11 millimeters a year by the end of 2021.

"“I think people just really have no idea what is coming, because we have no way of visualizing that through our own personal experiences, or that of the last 250 years,” said Randall Parkinson, a coastal geologist at Florida International University. “It’s not something where you go, ‘I know what that might look like because I’ve seen that.’ Because we haven’t.

"Scientists have offered several reasons for the surging sea levels in the South, including changes in land elevations and ocean circulation. A separate study pointed to variations in the Gulf Stream, a current coursing along the Gulf Coast, throughout the Caribbean and up the Atlantic Coast.

"Yet another study suggested that warming within the depths of the Gulf of Mexico is redistributing water from deeper areas to the shallows, contributing to the trend.

"Florida is uniquely vulnerable to sea level rise, with some 1,350 miles of coastlines, flat topography and porous geology.

"In Florida, the sea level rise similarly has accelerated, from a rate of some 3.1 millimeters a year since the mid 20th century to 5.9 millimeters a year since 1993 and 8.2 millimeters a year since 2003, according to a study based on 14 tidal gauges in the state.

"The data suggest that by 2050 the sea level rise in Florida would correspond with NOAA’s “intermediate,” “intermediate-high” and “high” scenarios, according to the study.

""The rate of sea level rise that we see now is four or five times faster than it was over the last several thousand years,” said Parkinson, who was involved in the study. “That’s like an inch every two and a half years, is where we’re at right now. So it’s in a person’s lifetime. Now you can notice that sea levels are rising.”"
