Glacier Legacy Contaminants

DISCLAIMER — Real Science, Deliberately Includes a Complication, No Framework Bridge

Why no UTAC/CREP/AFET bridge: not only because the cited literature already provides the necessary quantitative structure -- a deliberate choice. This project's highly speculative AFET/UTAC experiments must never stand in the way of climate/ecology topics being accessible and usable to people who don't work inside that construct and aren't looking for renormalization groups. Real, checkable science, without the burden of an unproven framework. See PACKAGE_REGISTRY.md's "Why no UTAC/CREP/AFET bridge in the climate/ecology series" (2026-08-31) in the GenesisAeon workspace root for the full canonical note.

Status: Real, independently verified science, including one finding that complicates the package's own headline narrative. NO UTAC/CREP/ AFET bridge.

glacier-legacy-contaminants-utac

GenesisAeon Package 109 — glaciers as chemical archives. The bridge connecting glacier-buffer-utac (P99), black-carbon-albedo-utac (P105), and freshwater-ecosystem-stressors-utac (P106): glaciers don't only lose water and darken from soot — they also store, and now release, decades of atmospherically-deposited persistent organic pollutants. Deliberately has no UTAC/CREP/AFET bridge — see DISCLAIMER.md.

For a plain-language explanation of the same topic (German, no jargon, written for general audiences), see WHITEPAPER.md.

Deliberately not one-sided

This package includes a real, important complication of the "glaciers release toxins" narrative, not just confirmation of it. release_implies_increased_food_web_exposure() returns False on purpose — real, measured contaminant release (confirmed at Lake Oberaar) does not automatically translate into higher ecological exposure everywhere it happens.
