Migration induced by sea-level rise could reshape the US population landscape
Estimated SLR [Sea Level Rise] net migrants (in-migrants minus out-migrants) for counties and core based statistical areas under the 1.8 m scenario and no adaptation.
It is likely that many communities will deploy a wide variety of adaptation measures, including sea walls, beach and marsh nourishment, pumps, or elevate homes and roads to protect both people and property, and IPCC reports have increasingly emphasized adaptation when discussing SLR. Global estimates of adaptive infrastructure for SLR could reach US$421 billion (2014 values) per year and could cost upwards of US$1.1 trillion in the US. However, the deployment of adaptation measures is driven by wealth for both cities and individuals.
[...] Florida could lose more than 2.5 million residents due to 1.8 m of SLR, while Texas could see nearly 1.5 million additional residents.
