In January, the National Oceanic and Atmospheric Administration published updated sea level scenarios for the United States. They included a new extreme scenario that would mean roughly 8 feet of global average sea level rise by 2100, but 10-12 feet along almost all U.S. shores outside of Alaska. Scientists consider the scenario unlikely, but increasingly plausible, especially with continued high emissions of greenhouse gases.
Climate Central released a suite of new maps, visuals and analyses fleshing out the implications, such as the 3D visualization below:

I have seen only a 4″ in 30 years, therefore 8′ is very unlikely in the next 30 years!!
U VA’s data from monitoring soil elevation tables and doing cryocoring in the Nature Conservancy’s Brownsville marshes indicates accretion is keeping up with sea level rise in that area, despite the fact that sea level rise here is higher than most places. The analysis of that dataset is current as of Thursday May 11th, 2017. More data was taken on May 12th, 2017 but has not been incorporated in that analysis yet.
This is 20 years of local hard data relevant to our area, not a model done by conjecture.
To clarify David Boyd’s well-documented, but rather complex insights for Larry, sea levels may have increased merely four inches for the past thirty years, but our a$$e$ will certainly drown in the next few decades. Move to higher ground if you plan to live long.
