REVIEW AND COMPARISON OF MULTIPLE PROXY RECORDS OF HOLOCENE PALEOENVIRONMENTS AND PALEOCLIMATE, NEW YORK STATE, USA
Other proxy data sets indicate coeval, though occasionally ambiguous, responses to environmental changes. Availability of proxies varies according to physiographic province, making direct sub-regional comparisons difficult. Although general paleoclimatic trends are apparent, weak chronological control and discontinuous records impede resolution and correlation between data sets. Local versus regional signals are often difficult to ascertain, while sensitivity and thresholds appear to be system-specific. Changes in a proxy record (e.g. vegetation) may also be driven by non-climatic influences such as time-dependent pedogenic pathways. Hence, the magnitude and timing of climatic and environmental transitions may not only differ according to the proxy used, but be obscured by other factors. These proxies, taken as a whole, indicate general patterns of paleoenvironmental and paleoclimatic change, but do not individually provide a detailed and accurate reconstruction of past environments. Future research should include (1) improving chronological control and (2) refining our understanding of both climatic and non-climatic variables affecting the environmental systems from which the proxies are taken.
