International audience; 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 and mitigation of such changes. We identify three broad areas where PEP science makes key contributions. 1. The patterns of global changes: Knowing the exact timing of glacial advances (synchronous or otherwise) during the last glaciation is critical to understanding inter-hemispheric links in climate. Work in PEPI demonstrated that the tropical Andes in South America was 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 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 abrupt climate events: We examine the relationship of ENSO to an abrupt 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 abrupt changes.

ABSTRACT For more than a century, from the 1870s to the 1980s, stockmen were important intermediaries and figures of power and influence in the construction, maintenance and renewal of the colonial order in New Caledonia. Social relations between Kanak and settlers working in the cattle ‘runs’ permitted a unique form of mobility spanning the frontier. The relations developed between chiefs and cattle farmers are central to the processes by which certain administrative chieftaincies emerged in the late‐nineteenth century, and by which Kanak entered the ‘political’ sphere in the second half of the twentieth century. With reference to the locality of Koné, this article traces the political alliances fashioned between Kanak stockmen and their employers in the context of colonisation, rebellion, evangelisation, post‐war political emancipation, local development and, finally, the struggle between supporters and opponents of independence in the 1980s.

Focusing on the Caigo Fleet Iron Company and its local competitors in Britain's Northeast, this article examines one company's response to changes in the steelmaking environment. By providing data at the firm level, the article is able to highlight specific contributing factors that are often invisible when scholars discuss Britain's industrial decline in the aggregate.

This consideration of how innovation was exploited in primary processing industries during the period of the second industrial revolution draws on case material from frozen-meat and dairy-processing industries in New Zealand between 1880 and 1910, examining how entrepreneurial networks successfully created commodity chains for the exportation of produce to U.K. markets. Latin American commodity chains are considered as a counterpoint. What is suggested is that despite the absence of large-scale firms and significant foreign capital, New Zealand producers, relying on network-based organizational forms, successfully entered overseas markets, capitalizing on information sharing, rapid diffusion of technology, and loose alliances that exploited complementary skills and assets.

During the six decades that extended from 1790 to 1850, British pin manufacturers were often slow to adopt new technology. Unfavorable economic conditions, particulary those spawned by the Napoleonic wars, were partly responsible for the lag between the invention and utilization of new techniques, but at other times, the shortcomings of inventors as salesmen of their inventions also contributed to the slow introduction of new technology. In this article Professors Dutton and Jones illustrate that the diffusion of new technology was (and is) anything but a costless and frictionless process, and they ultimately conclude that “this arcadian world of neo-classical simplicity would seem to be far removed from historical reality.”

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 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 glacial advances in the temperate and hyperhumid Southern Alps of New Zealand can be generated with very little thermal forcing. 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).

International audience; Recent excavations at Nawarla Gabarnmang in Jawoyn country, southwest Arnhem Land have produced a long sequence of AMS radiocarbon determinations on individual pieces of charcoal reliably associated with stone artefacts dating back to 45,180±910 cal BP. It represents one of the earliest radiocarbon-dated archaeological sites in Australia. Here we report on initial results.
