Climate change and sea level rise are discussed in general terms: rise in CO2 per year, rise in sea levels per year. Nature’s trends are steady on average by chaotic in the details. Sometimes things move a bit faster or slower or even reverse temporarily. During a time when sea level rise was supposed to grow about an inch, it jumped about five inches. Your location may vary. The variance is the point. Sea level rise of x inches per year is a good way to plan, but the reality is that sometimes it will rise faster, slower, or not. That difference can make a difference in a road washing out, a foundation being undermined, or a first floor being flooded. Sea level rise is no longer academic.
