Real aerosol-masking / shipping-sulfur unmasking science (IMO 2020) -- deliberately no UTAC/CREP bridge, honest spread of estimates + a relativizing null-result study included

aerosol-masking-utac

GenesisAeon Package 88 — real aerosol-masking / shipping-sulfur "unmasking" science (IMO 2020). Deliberately has no UTAC/CREP/AFET bridge — see DISCLAIMER.md.

What's real here

• Aerosol masking mechanism and the 2020 IMO shipping-fuel sulfur regulation (3.5% → 0.5% cap, ~80% SO2 reduction).
• An honest spread of independent radiative-forcing estimates (0.06 to ~0.2 W/m² across different studies/methods) — not a single cherry-picked number.
• Jordan & Henry (2024, Earth's Future): up to ~3 years of accelerated warming (UKESM1 model).
• Watson-Parris et al. (2025, ACP): a real, more recent relativizing finding that the global 20-year mean temperature signal is statistically consistent with no discernible global response — kept front and center, not buried.

Quickstart

pip install aerosol-masking-utac

from aerosol_masking_utac import rf_spread_wm2, watson_parris_2025_summary

low, high = rf_spread_wm2()
print(f"Independent RF estimates span {low}-{high} W/m^2")
print(watson_parris_2025_summary())
