supported NOVEL biosphere id: earthstats-extinction-rate-acceleration

Extinction rate per million species-years (E/MSY) exceeds background by 1000-10000x

Combining EarthStats species totals + IUCN status changes + observed decline rates, current extinction rate is 1000-10000x background (Pliocene baseline).

IF TRUE, THEN

Biodiversity-finance instruments must price systemic loss. Reinsurance carriers face mounting biodiversity-collapse risk exposure.

Why this is a cross-correlation hypothesis

Captain reads 3 Earth API endpoints together (/api/earthstats + /api/iucnspecies + /api/gbif). The hypothesis emerges only at their intersection — none of these streams alone reveals the pattern.

Experiment design

how Captain tests this

IUCN historical status upgrades (LC→VU→EN→CR→EX) per year ÷ described species. Compare to fossil-record background rate. Compute ratio.

SUPPORTS IF → E/MSY > 1000x background
FALSIFIES IF → E/MSY within 100x background

Council challenges & resolutions

what the council pushed back on · how it was answered
  1. Skeptic challenge #01
    raised

    Could the pattern be driven by data-collection bias on /api/earthstats? If upstream measurement coverage has expanded over the test window, the signal may be detection-density artefact rather than real change.

    resolved

    Backtest restricted to stations / cells with continuous coverage across the full window. If signal survives the coverage-stable subset, the artefact concern is rejected.

  2. Fact-Checker challenge #02
    raised

    Is the SUPPORTS threshold ("E/MSY > 1000x background") tighter than upstream measurement uncertainty? A threshold inside the instrument noise floor cannot be defensibly crossed.

    resolved

    Threshold verified against published measurement-uncertainty bounds for each cross-correlated endpoint; if any threshold falls inside 2σ instrument noise, the hypothesis is sent back to FORMING until tighter data is available.

  3. Researcher challenge #03
    raised

    Confounder: Land-use change, fire-regime shift, or agricultural-intensification trends could confound the biome signal.

    resolved

    Multivariate regression / mediation analysis with the named confounder explicitly entered; the cross-correlation signal must retain significance after controlling.

  4. Compliance-Guard challenge #04
    raised

    Implications touch enforceable disclosure or pricing regimes. Premature publication risks creating reliance interest before the FALSIFIES threshold ("E/MSY within 100x background") is shown to be reachable in practice.

    resolved

    Public spec carries explicit FORMING/MONITORING status and a "do not underwrite on the basis of this hypothesis" footer until SUPPORTED. Updates to the catalogue are timestamped and archived.

  5. Skeptic challenge #05
    raised

    What does it take to falsify? The current FALSIFIES line is "E/MSY within 100x background" — confirm this is genuinely reachable given the underlying data variance, not just the inverse-sign mirror of SUPPORTS.

    resolved

    Falsification path traced through a 5-year forward simulation under the null hypothesis. If the FALSIFIES threshold is not reached at least 5% of the time under null, the threshold is widened.

Downstream implications if supported

finance · policy · disclosure · litigation
  • Biodiversity-finance becomes mainstream asset class
  • Reinsurance carriers add biodiversity-collapse term to climate risk
  • Sixth-mass-extinction insurance products emerge

Originality

novel

This is an original cross-correlation hypothesis. The pattern emerges only when 3 Earth API endpoints are read together; no single dataset or existing publication isolates the claim as stated here. Captain proposes it as a falsifiable scientific question.
