“…Advances continue to be made in the New Zealand terrestrial realm, particularly in quantitative climatic and environmental reconstruction using beetles (Marra et al, 2006) and chironomids (Woodward and Shulmeister, 2006) and in refining glacial chronologies using surface exposure dating (Sutherland et al, in press) and process-based numerical models to assess the climatic significance of glacial advances (Rother and Shulmeister, 2005;Anderson and Mackintosh, 2006). A further major advance is the development of a newly derived pollen-based transfer function for deriving mean annual temperature from New Zealand pollen profiles .…”

“…Likewise, regional paleotemperature reconstructions using speleothems and fossil beetle assemblages indicate that cooling during the LGM and LGIT glacial advances was only moderate (Hellstrom et al, 1998) and possibly as little as −2 to −3 • C (Marra et al, 2006). The benefit of our mass balance model is that it provides a mechanism that resolves the occurrence of substantial glacial advances in New Zealand contemporaneous with reconstructed drier conditions and with only moderate atmospheric cooling.…”

“…fossil beetle assemblages show that LGM cooling was very moderate (Hellstrom et al, 1998) and possibly as little as 2 to 3 • C (Marra et al, 2006). The paleo-ELA 1 depression suggests a cooling in the vicinity of 4-5 • C (Porter, 1975;Soons, 1979).…”

Abstract. The relative timing of late Quaternary glacial advances in mid-latitude (40-55 • S) mountain belts of the Southern Hemisphere (SH) has become a critical focus in the debate on global climate teleconnections. On the basis of glacial data from New Zealand (NZ) and southern South America it has been argued that interhemispheric synchrony or asynchrony of Quaternary glacial events is due to Northern Hemisphere (NH) forcing of SH climate through either the ocean or atmosphere systems. Here we present a glacial snow-mass balance model that demonstrates that large scale glaciation in the temperate and hyperhumid Southern Alps of New Zealand can be generated with moderate cooling. This is because the rapid conversion of precipitation from rainfall to snowfall drives massive ice accumulation at small thermal changes (1-4 • C). Our model is consistent with recent paleo-environmental reconstructions showing that glacial advances in New Zealand during the Last Glacial Maximum (LGM) and the Last Glacial Interglacial Transition (LGIT) occurred under very moderate cooling. We suggest that such moderate cooling could be generated by changes in synoptic climatology, specifically through enhanced regional flow of moist westerly air masses. Our results imply that NH climate forcing may not have been the exclusive driver of Quaternary glaciations in New Zealand and that synoptic style climate variations are a better explanation for at least some late Quaternary glacial events, in particular during the LGIT (e.g. Younger Dryas and/or Antarctic Cold Reversal).

“…Traditional proxies such as ELA depression (Porter, 1975) and sea-surface temperature reductions in the Tasman Sea (Barrows and Juggins, 2005) indicate cooling of between 3-7 • C with most reconstructions indicating 4-5 • C. These values are lower than many other regions of the globe but recent efforts to quantify cooling on land have challenged even these moderate figures. Reconstructions from beetle work shows maximum cooling of ∼4 • C during the LGM (Marra et al, 2004) with cooling during parts of the LGM averaging only 1 • C from a site immediately proximal to an advanced glacier (Marra et al, 2006)! Physical modelling of ice accumulation conditions also suggest that cooling of as little as 2-4 • C could trigger large-scale ice advances in New Zealand (Rother and Shulmeister, 2005).…”

Inter-hemispheric linkages in climate change: paleo-perspectives for future climate change

Abstract. The Pole-Equator-Pole (PEP) projects of the PANASH (Paleoclimates of the Northern and Southern Hemisphere) programme have significantly advanced our understanding of past climate change on a global basis and helped to integrate paleo-science across regions and research disciplines. PANASH science allows us to constrain predictions for future climate change and to contribute to the management of consequent environmental changes. We identify three broad areas where PEP science makes key contributions.1. The pattern of global changes. Knowing the exact timing of glacial advances (synchronous or otherwise) during the last glaciation is critical to understanding interhemispheric links in climate. Work in PEPI demonstrated that the tropical Andes in South America were deglaciated earlier than the Northern Hemisphere (NH) and that an extended warming began there ca. 21 000 cal years BP. The general pattern is consistent with Antarctica and has now been replicated from studies in Southern Hemisphere (SH) regions of the PEPII transect. That significant deglaciation of SH alpine systems and Antarctica led deglaciation of NH ice sheets may reflect either i) faster response times in alpine systems and Antarctica, ii) regional moisture patterns that influenced glacier mass balance, or iii) a SH temperature forcing that led changes in the NH. This highlights the limitations of current understanding and the need for further fundamental paleoclimate research.2. Changes in modes of operation of oscillatory climate systems. Work across all the PEP transects has led to the recognition that the El Niño Southern Oscillation (ENSO) phenomenon has changed markedly through time. It now appears that ENSO operated during the last glacial termination Correspondence to: J. Shulmeister (james.shulmeister@canterbury.ac.nz) and during the early Holocene, but that precipitation teleconnections even within the Pacific Basin were turned down, or off. In the modern ENSO phenomenon both inter-annual and seven year periodicities are present, with the inter-annual signal dominant. Paleo-data demonstrate that the relative importance of the two periodicities changes through time, with longer periodicities dominant in the early Holocene.3. The recognition of climate modulation of oscillatory systems by climate events. We examine the relationship of ENSO to a SH climate event, the Antarctic cold reversal (ACR), in the New Zealand region. We demonstrate that the onset of the ACR was associated with the apparent switching on of an ENSO signal in New Zealand. We infer that this related to enhanced zonal SW winds with the amplification of the pressure fields allowing an existing but weak ENSO signal to manifest itself. Teleconnections of this nature would be difficult to predict for future abrupt change as boundary conditions cannot readily be specified. Paleo-data are critical to predicting the teleconnections of future changes.
