Sweatman 2021: the proponent synthesis
- what the source states
- A review of the impact evidence argued that the accumulated proxy record — spherules, platinum, nanodiamonds, melt products, burning signals across many sites — collectively supports the Younger Dryas impact hypothesis strongly, and that the critical literature has mischaracterized the state of the evidence.
- what we infer
- The strongest peer-reviewed statement of the proponent case, carried at weak strength because it is a synthesis of the same primary studies whose replication and identification problems this case documents — aggregation does not launder non-independent, disputed lines into strong evidence.
- limitations
- Its consensus characterization drew a published methodological comment (Jorgeson et al. 2022) and author response.
- Single author, closely identified with the proponent research program.
