Climate Change-Planning for Adaption and Resiliency
Resilient-ability to recover readily from adversity, or the like; buoyancy. Adaptation-It means changing something to fit the circumstance, or changing an action or response to better deal with something.
Climate Change and Sea Level Rise
THE HOCKEY STICK
The Message Temp lags CO2
Medieval Warm Period
Little Ice Age
Moberg et al, 2005
Six Factors Contributing to Relative Sea Level Rise
1.Thermal expansion of seawater 2.Melting of glaciers and ice caps 3.Ice sheets (Greenland West Antarctica)????? 4. Post glacial
rebound and subsidence
5.Slowing of density currents i.e. Gulfstream 6.Loss of gravitational pull of ice sheets

National Policy The Federal Coastal Zone Management Act
The Congress finds and declares that it is the national policy (1)to preserve, protect, develop, and where possible, to restore or enhance, the resources of the Nation's coastal zone for this and succeeding generations………. (B) the management of coastal development to minimize the loss of life and property caused by improper development in flood-prone, storm surge, geological hazard, and erosionprone areas and in areas likely to be affected by or vulnerable to sea level rise, land subsidence, and saltwater intrusion, and by the destruction of natural protective features such as beaches, dunes, wetlands, and barrier islands,
Planning for Coastal Hazards Requires Looking at Long Term and Instantaneous Adjustment.
We Already Have World Class Policies For Coastal Hazards But They Aren't Enough
