The reason South Florida is so vulnerable to sea level rise lies beneath our feet. When heavy rains fall or seas rise, groundwater levels do too. But most local, state and fed agencies in Florida don't account for this. It could mean we see more flooding, faster, than expected.

Adding in the groundwater connection doesn't necessarily show flooding in new areas. @semerriam.bsky.social overlaid flood complaints in Fort Lauderdale with Broward's future scenarios mapping and found they match pretty well
