Empirical Bayesian multi-stream attribution matrix: see why scientific consensus is not decreed by a council, but calculated through converging, independent observational lines of evidence.

In climate science, the word "settled" is rarely used in peer-reviewed literature. Instead, international scientific consensus adheres to the formal IPCC Uncertainty Guidance, mapping rigorous statistical likelihood intervals to standardized linguistic terms:
99 – 100% probability. Exceptionally high statistical confidence supported by multiple independent physical, chemical, and satellite measurements.
95 – 100% probability. Standard threshold for formal scientific rejection of the natural-only null hypothesis (p < 0.05 equivalent).
90 – 100% probability. Established cross-observational agreement where natural solar/orbital cycles fail to explain magnitude or vector.
66 – 100% probability. General scientific consensus where residual secondary feedback uncertainties (e.g. aerosol cloud albedo) remain under research.
Critics often claim consensus is a political agreement among committees. But under Bayes’ Theorem:
P(Anthropogenic | E₁ ∩ E₂ ... ∩ E₆) = [ P(E₁...E₆ | H) · P(H) ] / [ P(E₁...E₆ | H)·P(H) + P(E₁...E₆ | ¬H)·P(¬H) ]
Because the observational streams test disjoint physical domains—e.g., if solar output caused surface heating, the stratosphere would warm; instead, 40+ years of satellite radiometry proves stratospheric cooling while the troposphere heats—the likelihood of all six systems manifesting this exact fingerprint under pure natural variation is less than 1 in 100,000.
