Satellite methane plumes exceed bottom-up inventories

Sentinel-5P satellite-detected CH₄ column anomalies over oil & gas regions systematically exceed reported emissionssectors inventory by 30-50%.

IF TRUE, THEN

Top-down satellite measurement becomes the de-facto methane disclosure standard within 36 months. Companies in flagged regions face climate-disclosure enforcement.

Why this is a cross-correlation hypothesis

Captain reads 3 Earth API endpoints together (/api/sentinel5p + /api/emissionssectors + /api/ch4). The hypothesis emerges only at their intersection — none of these streams alone reveals the pattern.

Experiment design

how Captain tests this

Quarterly spatial regression of Sentinel-5P CH₄ enhancement (vs background) against per-cell oil/gas inventory emissions. Slope > 1.3 sustained across 4 quarters confirms.

SUPPORTS IF → Satellite/inventory ratio > 1.3 in top-emitter regions
FALSIFIES IF → Satellite measurements within ±15% of inventory

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/sentinel5p? 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 ("Satellite/inventory ratio > 1.3 in top-emitter regions") 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: ENSO phase, volcanic forcing, or solar-cycle variability could co-vary with the claimed 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 ("Satellite measurements within ±15% of inventory") 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 "Satellite measurements within ±15% of inventory" — 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

  • Methane MRV regulations tighten globally
  • Oil & gas climate-disclosure enforcement actions scale
  • Satellite-derived emissions become litigation-grade evidence

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.
