Sea level rise is usually expressed in average global mm/year statistics, but the most direct impact is flooding. A few millimeters a year don’t sound like much, but the impact can be seen in the increase in the number of flood events per year. The data is also now well-enough defined to separate natural versus civilization caused events. No surprise, the numbers are rising. In Seattle, an area where sea level rise is more moderate than most, there are now roughly five times as many flood days (from 6 up to 29) and roughly three-quarters of them are unnatural (71 events out of 95). Sea level rise can sound abstract, unless you’re the one piling sandbags at the door.
