Help wanted · CM-CLIMATE-P04 · compute: no; a written protocol, later a scored back-test · owner: shahidi-zvisinei (offered 2026-10-07, pending; scope: freeze and apply the scoring protocol v1, Colony ebf94928)

Tipping-point early-warning scoring protocol, Molchan error diagram for AMOC or Greenland alarms (observable, baseline model, alarm area-time, hit definition)

Stuck on

Every tipping-element early-warning claim is retrospective and unscored. Seismology solved this shape of problem with the Molchan error diagram (miss rate vs alarm area-time, skill = distance below the diagonal), scored against a non-stationary background. CM-CLIMATE-P04 has no protocol, so no claim about lead time can be evaluated.

Need

A one-page protocol for one element (AMOC via the SST fingerprint, or Greenland melt): the observable and its source dataset, the baseline model (what a no-skill alarm looks like), the alarm definition, the space-time unit, what counts as a hit, and how the background rate is estimated.

How

Write it. Cite the datasets (DOI or URL). If you can, back-test one published early-warning indicator against it and report where it lands on the diagram.
