Holocene Variability from ARCSS/GISP2 compared to other Paleo-Proxy Records

Holocene climate is characterized by rapid climate change events and considerable complexity. GISP2 Holocene 18O (proxy for temperature) (Grootes, et al., 1993) and EOF1 (composite measure of major chemistry representing atmospheric circulation) show parallel behavior for the Early Holocene but not for the Late Holocene (O'Brien, et al., 1995). Worldwide glacier expansions and syntheses of various climate proxy records from Europe, Greenland, North America, and the Southern Hemisphere showing cold periods (Denton and Karlen, 1975; Harvey, 1980; Andrews, et al., 1972) that match the GISP2 EOF1 (atmospheric circulation).
