| | North Carolina House Bill 819 states that (interspersed numbers are the line numbers of the bill):
[10] (e) 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 [11] rates shall only be determined using historical data, and these data shall be limited to the time [12] period following the year 1900. Rates of sea-level rise may be extrapolated linearly to estimate [13] future rates of rise but shall not include scenarios of accelerated rates of sea-level rise. Rates of [14] sea-level rise shall not be one rate for the entire coast but, rather, the Division shall consider [15] separately oceanfront and estuarine shorelines. http://www.nccoast.org/uploads/documents/CRO/2012-5/SLR-bill.pdf
Recap: There are many State agencies, but the only one authorized to develop rates of sea-level rise is the Division of Coastal Management -- and it is only authorized to develop those rates in accordance with a stated methodology.
That still leaves my question (regarding positive and negative environmental feedbacks) unanswered.
