Data is factual information, as in measurements and statistics.
A scenario is a description of what could possibly happen.

When it comes to local sea level rise, I’ll go with data over scenarios.

The original post show the NOAA stations for Virginia and the 2015 numbers for all but Portsmouth which ends in 1987 and Gloucester Point which ends in 2003. Last report for Chesapeake Bay Bridge Tunnel is 2017 as of October, 2020. All other stations were updated to also show 2019 information. (Click on the link to go to the NOAA site.)
