The question, scope, and sources behind this Registry record.
Satellite-era observations report a global mean sea-level rise rate of several millimetres per year, with the estimate depending on the time window.
Estimate the global mean sea-level trend over a stated satellite or tide-gauge interval with corrections recorded.
Sea level is a spatiotemporal field rather than a single tide-gauge number. Estimates combine satellite altimetry, tide gauges, glacial isostatic adjustment, and corrections for instrument drift and ocean dynamics.

Current frontiers derived from accepted Claims.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.

Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
