N₂O is accelerating from agricultural intensification

N₂O growth rate is accelerating in regions of agricultural intensification (Asia, S America), driven by synthetic fertilizer use. Sentinel-5P confirms surface-attribution.

IF TRUE, THEN

N₂O contribution to climate forcing reaches 10% by 2035 (from ~6% today). Methane abatement focus needs to share with N₂O abatement.

Why this is a cross-correlation hypothesis

Captain reads 3 Earth API endpoints together (/api/n2o + /api/sentinel5p + /api/emissionssectors). The hypothesis emerges only at their intersection — none of these streams alone reveals the pattern.

Experiment design

how Captain tests this

Multi-region N₂O growth rate regression on agricultural-use indicators. Test for regional-vs-uniform pattern.

SUPPORTS IF → Growth rate in agricultural intensification regions > 2× global average
FALSIFIES IF → Growth rate uniform across regions

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/n2o? 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 ("Growth rate in agricultural intensification regions > 2× global average") 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 ("Growth rate uniform across regions") 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 "Growth rate uniform across regions" — 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
  • Agricultural climate-policy elevates N₂O alongside CH₄
  • Fertilizer-efficiency carbon credits emerge as asset class
  • Food security × climate finance convergence

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.
