Multiple comprehensive scientific assessments and atmospheric models demonstrate that aviation soot and associated particulate emissions exert a measurable effective radiative forcing on the climate over specific time frames.
The claim is specific, empirical, and contestable, passing Step 0. The retrieved literature (especially papers [0], [1], and [3]) explicitly calculates or models the effective radiative forcing (ERF) and radiative forcing (RF) of aviation-related soot and aerosol-cloud interactions over specific periods, providing clear and direct support for the claim. Therefore, the balance verdict is SUPPORTED.
