Coastal N.C. counties fighting sea-level rise prediction

State lawmakers are considering a measure that would limit how North Carolina prepares for sea-level rise, which many scientists consider one of the surest results of climate change.

Federal authorities say the North Carolina coast is vulnerable because of its low, flat land and thin fringe of barrier islands. A state-appointed science panel has reported that a 1-meter rise in sea level is likely by 2100.

…

Several local governments on the coast have passed resolutions against sea-level rise policies.

When the General Assembly convened this month, Republican legislators went further.

They circulated a bill that authorizes only the coastal commission to calculate how fast the sea is rising. It said the calculations must be based only on historic trends – leaving out the accelerated rise that climate scientists widely expect this century if warming increases and glaciers melt.

The bill, a substitute for an unrelated measure the N.C. House passed last year, has not been introduced. State legislative officials say they can’t predict how it might be changed, or when or whether it will emerge.

Longtime East Carolina University geologist Stan Riggs, a science panel member who studies the evolution of the coast, said the 1-meter estimate is squarely within the mainstream of research.

“We’re throwing this science out completely, and what’s proposed is just crazy for a state that used to be a leader in marine science,” he said of the proposed legislation. “You can’t legislate the ocean, and you can’t legislate storms.”

NC Considers Making Sea Level Rise Illegal
…
In a story first discussed by the NC Coastal Federation and given more play May 29 by the News & Observer of Raleigh and its sister paper the Charlotte Observer, a group of legislators from 20 coastal NC counties whose economies will be most affected by rising seas have legislated the words “Nuh-unh!” into the NC Constitution.

Okay, cheap shot alert. Actually all they did was say science is crazy. There is virtually universal agreement among scientists that the sea will probably rise a good meter or more before the end of the century, wreaking havoc in low-lying coastal counties. So the members of the developers’ lobbying group NC-20 say the sea will rise only 8 inches, because … because … well, SHUT UP, that’s because why.

That is, the meter or so of sea level rise predicted for the NC Coastal Resources Commission by a state-appointed board of scientists is extremely inconvenient for counties along the coast. So the NC-20 types have decided that we can escape sea level rise – in North Carolina, anyhow – by making it against the law. Or making MEASURING it against the law, anyhow.

Here’s a link to the circulated Replacement House Bill 819. The key language is in section 2, paragraph e, talking about rates of sea level rise: “These rates shall only be determined using historical data, and these data shall be limited to the time period following the year 1900. Rates of seas-level rise may be extrapolated linearly. …” It goes on, but there’s the core: North Carolina legislators have decided that the way to make exponential increases in sea level rise – caused by those inconvenient feedback loops we keep hearing about from scientists – go away is to make it against the law to extrapolate exponential; we can only extrapolate along a line predicted by previous sea level rises.
