Interesting from IPCC SROCC report: “Globally, it is estimated that about 33,700 km2 of land has been gained from the sea during the last 30 years (about 50% more than has been lost), with the biggest gains being due to land reclamation in places like Dubai, Singapore and China”

   More: “There is limited evidence of migration occurring directly as a consequence of impacts associated with environmental change generally and SLR specifically.”

   And more: “There is robust evidence of disasters displacing people worldwide, but limited evidence that climate change or SLR is the direct cause.”

   IPCC SROCC clearly treats RCP8.5 as BAU: “Under unmitigated emissions (RCP8.5), coastal societies, especially poorer, rural and small islands societies, will struggle to maintain their livelihoods and settlements during the 21st century.”

   Also includes projected SLR based on postulated 5 deg C global temp increase form 2100, as comparison to RCP8.5 (“unmitigated emission” aka BAU)
   
   All problematic from the standpoint of policy/risk
