Abstract

The magnitude of recent warming, and the variability of climate on centennial-millennial time scales are compromised by questions concerning the ability of tree rings to capture low-frequency climate fluctuations. Annually laminated stalagmite records can potentially provide a low-frequency climate archive through variations in annual growth rate. Presented here is an initial attempt to demonstrate the applicability of annually laminated stalagmite series to a large-scale climate reconstruction, by producing a 500-year Northern Hemisphere temperature reconstruction. The reconstruction shows an overall warming trend with a magnitude of 0.65 K and several other low-frequency characteristics consistent with other independent Northern Hemisphere archives. The result is sufficiently encouraging to warrant significant future effort in characterising annual growth rate records from laminated speleothems. Copyright (C) 2006 Royal Meteorological Society.
