North Carolina House Bill 819 Did NC Make Sea Level Rise Illegal?
What is in NC House Bill 819? April 28, 2011House Bill Passed The Division of Coastal Management shall be the only State agency authorized to develop rates of sea-level rise and shall do so only at the request of the Commission. 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 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. http://www.nccoast.org/uploads/documents/CRO/2012-5/SLR-bill.pdf

June 12, 2011Senate Bill Passed (c) The Coastal Resources Commission shall be the only State agency authorized to define rates of sea-level rise for regulatory purposes… Historic rates of sea-level rise may be extrapolated to estimate future rates of rise but shall not include scenarios of accelerated rates of sea-level rise unless such rates are from statistically significant, peer-reviewed data and are consistent with historic trends. http://d20b91ibeoos7k.cloudfront.net/static/billtext/40499.pdf

August 3, 2011Bill Becomes Law (c) Nothing in this section shall be construed to prohibit a county, municipality, or other local government entity from defining rates of sea-level change for regulatory purposes. (e) The Commission shall be the only State agency authorized to define rates of sea-level change for regulatory purposes. SECTION 2.(b) The Coastal Resources Commission …shall not define rates of sea-level change for regulatory purposes prior to July 1, 2016. http://d20b91ibeoos7k.cloudfront.net/static/billtext/40900.pdf

So, are (how are) the sea levels rising? Let’s zoom in on recent data Sea Level Rise. CSIRO, n.d. Web. 26 Nov. 2012. <http://www.cmar.csiro.au/sealevel/index.html>.
GMSL: 1993 - 2009 Looks pretty linear; let’s fit a linear model…
Passes through (0,0) Slope = Passes through (h,k) Slope =
16 (2001,25) 45
Passes through (0,0) Slope = Passes through (h,k) Slope = The linear regression line Passes through ) Slope minimizes
Let’s find a least square linear model… Minimize sum error^2 By changing a
Using this linear model, global mean sea level will rise… 2.8 mm per year 0.0028 m per year 0.028 m per 10 years 0.28 m per 100 year 1 m in about 357 years

High TIDE AND Low TIDE In North Carolina, the difference between high and low tide levels hovers around three feet. SPRING TIDES AND NEAP TIDES The moon and sun pass the earth in different positions throughout the year. For this reason, the height of the local tides changes from time to time. The maximums are called spring tides, when the tidal range on a beach is the greatest. This maximum happens when the moon is either full or new. The minimum or neap tide occurs when the moon is in its first or third quarters. The spring tide at Atlantic Beach, North Carolina, is typically six feet and the neap tide is two feet. Tides.
