Sea Level Rise Tracker Screensaver
The Sea Level Rise Tracker screensaver shows the real, live monthly sea level record from a long-running NOAA tide gauge, with its own published long-term trend. It is free, runs in your browser, and ESC exits.
How the Sea Level Rise Tracker screensaver works
The saver reads the real monthly mean sea level record from a NOAA Center for Operational Oceanographic Products and Services tide gauge station.
The real published long-term rise trend, in millimeters per year, is computed from the station's own data.
The pipeline refreshes the record on the source's own real monthly schedule.
No key is required for the published NOAA data.
A worked example
The real monthly mean sea level bounces with seasonal cycles, but the underlying real trend line steadily climbs over decades of measurement.
Settings & tips
- Accent recolours the trend line.
- Figures are real tide-gauge measurements, not modeled projections.
- The record updates monthly on NOAA's own real schedule.
Frequently asked questions
- Is this real tide gauge data?
- Yes — a real, long-running NOAA tide gauge station's own published record.
- Is a key needed?
- No. NOAA publishes this data freely.
- Does this reflect the whole ocean?
- It reflects one real long-running station; global sea level draws on many such stations plus satellite data.
- Is it free?
- Yes — free, no download, in your browser.
