Holocene Proxy Climate Series Should Account for the Site's Elevation, the Variable's Sensitivity to Elevation History and Time-lagged Effects: Three Examples

Abstract. When making multi-proxy reconstructions over Holocene-long periods, an argument is presented that the elevation of the sites used and/or their elevation history must be taken into account before their proxy records (of temperature or precipitation) are included in the reconstruction. It is shown that to ignore elevation, results in first order errors in the reconstruction, especially in regions under (or close to) the degrading ice sheet. Also it is argued that when assessing the signature of a given putative global event (like the 4.2ka event), one must allow for there being a complex signature wrt. location, elevation and time lagged variables. Three specific examples are used to illustrate these points.

Short summary
When making multi-proxy reconstructions over Holocene-long periods, the elevation of the sites used and/or their elevation history must be taken into account before their proxy records are included in the reconstruction. Also, when assessing the signature of a given putative global event (like the 4.2 ka event), one must allow for there being a complex signature wrt. location, elevation and time lagged variables. Three specific examples are used to illustrate these points.
