No, Roanoke Times, Climate Change Is Not To Blame for Virginia Beach’s Flooding – Watts Up With That?
A Google information search of the time period “local weather change” turns up a latest story within the Roanoke Occasions claiming human induced local weather change is inflicting elevated incidences of flooding in Virginia Seaside, Virginia. That is false. Flooding could also be worsening in Virginia Seaside, and human actions could also be contributing to it, however analysis signifies a local weather change induced enhance within the charge of sea stage rise is to not blame.
A narrative, titled “Virginia Beach confronts inescapable costs of rising seas,” discusses a $568 million bond difficulty being proposed to enhance infrastructure and reduce future harm from flooding within the area. If voter don’t approve the bond, the story warns “the town might lose billions of {dollars} within the subsequent half-century as recurrent flooding inundates roads, companies and houses.”
The Roanoke Occasions the proceeds to incorrectly attribute the hazard of recurrent future flooding in Virginia Seaside to local weather change induced rising seas.
“The referendum underscores the mounting prices of adapting to local weather change for U.S. cities,” writes the Roanoke Occasions. “The necessity for cash to guard communities in opposition to local weather change is rising throughout the globe ….”
Information present seas usually are not rising at an uncommon charge within the Chesapeake Bay area the place Virginia Seaside is situated.
As mentioned in a latest Climate Realism article, the Nationwide Oceanic and Atmospheric Administration has maintained a tidal gauge at Sewell’s Level in Norfolk because the Nineteen Twenties. The tidal data, as proven within the NOAA graph under, present the tempo of sea-level rise stays the identical now because it was 100 years in the past – when there was minimal human-emitted carbon dioxide within the environment.
NOAA has maintained three different tidal gauges within the Norfolk area, courting again to the Thirties, Fifties, and Seventies, respectively. Not one of the different three present any acceleration, both.
Every of those tide gauges is inside 30 miles of Virginia Seaside and none present uncommon charges of sea stage rise or an rising charge in latest many years.
To the extent flooding has elevated within the Chesapeake Bay area and Virginia Seaside particularly, analysis reveals it is because of localized land subsidence. In accordance with a U.S. Geological Survey (USGS) report, titled “Land Subsidence and Relative Sea-Level Rise in the Southern Chesapeake Bay Region,” states:
Land subsidence has been noticed because the Nineteen Forties within the southern Chesapeake Bay area at charges of 1.1 to 4.8 millimeters per 12 months (mm/yr), and subsidence continues at present.
This land subsidence helps clarify why the area has the best charges of sea-level rise on the Atlantic Coast of the US. Information point out that land subsidence has been liable for greater than half the relative sea-level rise measured within the area. Land subsidence will increase the danger of flooding in low-lying areas, which in flip has essential financial, environmental, and human well being penalties for the closely populated and ecologically essential southern Chesapeake Bay area.
The aquifer system within the area has been compacted by intensive groundwater pumping within the area at charges of 1.5- to three.7-mm/yr; this compaction accounts for greater than half of noticed land subsidence within the area.
The proposed bond difficulty could also be wanted to forestall elevated incidences of flooding in Virginia Seaside, however it should solely work to forestall flooding if the “fixes” funded by it deal with the precise causes of the issue. Native water withdrawals, wetlands conversion, and land compaction are in charge for Virginia Seaside’s flooding woes, not local weather change. Higher land and water administration, not fossil gasoline use restrictions, are wanted to cut back the incidences of houses and companies in Virginia Seaside flooding.
