A public art piece called a reverse time capsule marks current king-tide height, midcentury projections, and an end-of-century worst-case on Puget Sound to make sea level rise tangible for the community.
A stone bench and five-foot pillar installed on Bainbridge Island visually compare today’s king-tide line to midcentury and end-of-century sea level projections.
The project, conceived by scientist Lara Hansen of EcoAdapt, calls itself a 'reverse time capsule'—designed to preserve the future for present-day viewers.
The bench lets people place their feet at the current king-tide mark and sit about 18 inches above it, illustrating midcentury high-end projections.
# What the installation is
On Bainbridge Island in Puget Sound, community members placed a stone bench by the water and added a five-foot stone pillar nearby. The design shows three reference points in physical space: the current king-tide mark, a midcentury sea-level projection, and a higher end-of-century projection. The artist-scientist behind the piece calls it a "reverse time capsule" because it preserves future conditions for people living now to see.
# How people experience it
Visitors can stand or rest their feet at the current king-tide line and then sit on the bench, which positions a seated person roughly 18 inches above that line. That elevated seat corresponds to a midcentury, high-end sea-level projection. The adjacent five-foot pillar marks one of the worst-case projections for the end of the century. The piece is meant to turn abstract numbers into a simple, physical comparison people can feel and remember.
# Who made it and why
# What the markers represent
The current king-tide mark shows how high water reaches during very high tides today, a relevant baseline for local flooding risk. The bench elevates a seated person about 18 inches above that baseline to represent a midcentury, high-end projection. The five-foot pillar denotes a higher projection associated with severe end-of-century scenarios. The installation uses these physical heights to communicate relative differences across decades without relying on technical charts.
# Intended effects and audience
The installation targets local residents and visitors who encounter the seaside bench. Its purpose is experiential: to prompt reflection about local flood risk and future shoreline change. By presenting projections in a plain, physical way, the piece aims to engage people who might not respond to technical forecasts. It is positioned as a community-facing prompt for awareness and consideration of adaptation choices.
# Reporting credit
The project and interview excerpts were reported for Yale Climate Connections by Ethan Freedman with ChavoBart Digital Media. The concept and comments attributed to Lara Hansen were included in that coverage.
# What the piece does not do
The installation communicates relative future heights rather than site-specific engineering guidance or policy prescriptions. It is a public demonstration intended to inform and provoke thought, not a structural flood protection measure.
# Practical takeaway
Seeing projected sea-level differences in human-scale form can change how people understand local flood risk. For communities on Puget Sound and similar coasts, places where king tides already cause concern, a visible marker system like this offers a low-tech way to communicate projections and spark local conversation about adaptation choices.
You've surely seen interactive maps showing the effects of the sea level rising, but Sliding Shores makes a game of it: you get a beautifully-rendered globe and a slider to raise or lower the oceans. There's a load of presets, from "oceans drained" to "drown Everest," a feat not even Waterworld managed. — <a href="http
