Legislators in North Carolina recently went one better than King C’Nut (Canute). The king of Denmark, England, Norway and parts of Sweden during various periods between 1018 and 1035, famously and unsuccessfully tried to hold back the incoming tide. The now mythic story tells of Canute’s arrogance. Not to be outdone, North Carolina’s state legislature recently passed a law that bans state agencies from reporting that sea-level rise is accelerating.

The bill From North Carolina states:

“… rates shall only be determined using historical data, and these data shall be limited to the time period following the year 1900. Rates of sea-level rise may be extrapolated linearly to estimate future rates of rise but shall not include scenarios of accelerated rates of sea-level rise.”

This comes hot on the heals of the recent revisionist push in Virginia where references to phrases such as “sea level rise” and “climate change” are forbidden in official state communications. Last year of course, Texas led the way for other states following the climate science denial program when the Texas Commission on Environmental Quality, which had commissioned a scientific study of Galveston Bay, removed all references to “rising sea levels”.

Less than two weeks after the state’s senate passed a climate science-squelching bill, research shows that sea level along the coast between N.C. and Massachusetts is rising faster than anywhere on Earth.

Could nature be mocking North Carolina’s law-makers? Less than two weeks after the state’s senate passed a bill banning state agencies from reporting that sea-level rise is accelerating, research has shown that the coast between North Carolina and Massachusetts is experiencing the fastest sea-level rise in the world.

Asbury Sallenger, an oceanographer at the US Geological Survey in St Petersburg, Florida, and his colleagues analysed tide-gauge records from around North America. On 24 June, they reported in Nature Climate Change that since 1980, sea-level rise between Cape Hatteras, North Carolina, and Boston, Massachusetts, has accelerated to between 2 and 3.7 millimetres per year. That is three to four times the global average, and it means the coast could see 20–29 centimetres of sea-level rise on top of the metre predicted for the world as a whole by 2100 ( A. H. Sallenger Jr et al. Nature Clim. Change http://doi.org/hz4; 2012).

“Many people mistakenly think that the rate of sea-level rise is the same everywhere as glaciers and ice caps melt,” says Marcia McNutt, director of the US Geological Survey. But variations in currents and land movements can cause large regional differences. The hotspot is consistent with the slowing measured in Atlantic Ocean circulation, which may be tied to changes in water temperature, salinity and density.

North Carolina’s senators, however, have tried to stop state-funded researchers from releasing similar reports. The law approved by the senate on 12 June banned scientists in state agencies from using exponential extrapolation to predict sea-level rise, requiring instead that they stick to linear projections based on historical data.

Following international opprobrium, the state’s House of Representatives rejected the bill on 19 June. However, a compromise between the house and the senate forbids state agencies from basing any laws or plans on exponential extrapolations for the next three to four years, while the state conducts a new sea-level study.

According to local media, the bill was the handiwork of industry lobbyists and coastal municipalities who feared that investors and property developers would be scared off by predictions of high sea-level rises. The lobbyists invoked a paper published in the Journal of Coastal Research last year by James Houston, retired director of the US Army Corps of Engineers’ research centre in Vicksburg, Mississippi, and Robert Dean, emeritus professor of coastal engineering at the University of Florida in Gainesville. They reported that global sea-level rise has slowed since 1930 ( J. R. Houston and R. G. Dean J. Coastal Res. 27 , 409 – 417 ; 2011) — a contention that climate sceptics around the world have seized on.

Speaking to Nature, Dean accused the oceanographic community of ideological bias. “In the United States, there is an overemphasis on unrealistically high sea-level rise,” he says. “The reason is budgets. I am retired, so I have the freedom to report what I find without any bias or need to chase funding.” But Sallenger says that Houston and Dean’s choice of data sets masks acceleration in the sea-level-rise hotspot.
