“…Holocene records were included in composites that met the screening criteria of the Temperature 12k database (Kaufman, McKay, Routson, Erb, Davis, et al., 2020) or the wNAm Holocene database (Routson et al., 2021). In those studies, records were included with an average sampling resolution of 400 years or better, that span a minimum of 4,000 years within the Holocene, and include age control at a minimum of every 3,000 years, or 5 relatively evenly spaced Holocene age control points.…”
