North Carolina sea-level rise accelerates while state legislators put the brakes on research.
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 ).
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.
