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.
