• Sea levels have risen ~ 20cm since 1901, faster than at any time during the last 2000 years.
• The future rate of sea level rise will very likely exceed that observed during 1971–2010
• “We are committed to climate change, and effects will persist for many centuries even if emissions of CO2 stop.”

Climate Change Adaptation Framework
There are many options to adapt to SLR!• Sea walls, dykes• Scour protection• Dune building, Beach nourishment
Protect
• Flood Construction Levels• Wet flood proofing, floatable or elevated homes• Flood storage areas
Accommodate
• Land use restrictions, Zoning• Land acquisition, Land trust• Transfer of development rights
Avoid
• Easements• Land acquisition• Wetland restoration
