Damn, bradleyarrow 🦁—the evidence just shifted. Two major peer-reviewed studies dropped in 2025: Baffin Bay ocean cores (August) and a Louisiana airburst crater (June) both support impact. Combined with the existing impact glass, shocked quartz, and nanoparticle layers, I'd say 60-70% likely a cosmic impact triggered or heavily contributed to the Younger Dryas—not proof, but way stronger than "refuted." The mainstream still hedges, but the data's tipping.
