“…5.7, 5.8); indeed (6) comparison of individual reconstructions of Northern Hemisphere temperatures with the Intergovernmental Panel on Climate Change's earlier somewhat muted successive summary curves shows considerable difference (compare IPCC, 2001: Figs 2.20, 2.21;IPCC, 2007: Fig. 6.10, also Box 6.4, Fig 1); (7) it had previously been thought that its expression was not influenced by human activity, whereas the 'plague' claim in the 'early anthropogenic' hypothesis of Ruddiman (2003) implies otherwise; (8) it largely precedes what some have viewed and attempted to define as a new epoch, representing evidence of widespread human influence on global systems: the so-called Anthropocene (Crutzen and Stoermer, 2000;Zalasiewicz et al, 2015)); (9) its effects upon some human societies appear to have been profound in particular regions of the world, notably in Greenland (Ribeiro et al, 2012), Norway (Lamb, 1995) and the Alps (Le Roy Ladurie, 1971[1967); and yet (11) its very existence as a coherent, globally climatically defined period has been questioned (compare Mann et al, 1999with Goosse et al, 2005see Matthew and Briffa, 2005); although (12) recent work implies an in-phase relationship between the Southern and Northern Hemispheres (Chambers et al, 2014;Simms et al, 2012).…”

Here we present an ~2000 year high-resolution glaciochemical record from the South Pole. Significant changes in chemical concentrations, accumulation rate, stable water isotopes and deuterium excess records are captured during the period ~1400-1700 CE, indicating a reorganization of atmospheric circulation that occurred in two steps: ~1400-1425 CE and ~1650-1700 CE. Major declines in dust and SO4 2concentrations are observed ~1400 CE suggesting poleward contraction of the southern circumpolar vortex and potential intensification of westerly air flow, accompanied by a sea ice decrease in the Weddell Sea and potentially also in the Indian sector of the Southern Ocean. The changes in stable water isotopes, deuterium excess, NO3concentration and accumulation rate characterize a second shift in atmospheric reorganization between 1650-1700 CE, reflecting increased marine air mass intrusions and subsequent reduction of the katabatic winds, and a shift to a colder moisture source for South Pole precipitation. These internally consistent changes involving atmospheric circulations and sea ice conditions are also in line with those identified for the recent period, and include associations with the large-scale teleconnections of El Niño Southern Oscillation (ENSO) and the Southern Annular Mode (SAM).

Peat archives offer a diverse range of physical and chemical proxies from which it is possible to study past environmental and ecological changes. Direct numerical calibration and verification is difficult so process-based and mechanistic studies are therefore required to establish and quantify links between environmental changes and their associated proxy-responses. Traditional 'space-for-time' calibrations provide a solution to this calibration problem, but are often unable to isolate a single environmental variable from other potentially confounding variables. In this study, we explored the potential of a site-specific 'space-for-time' approach applied to a hummock-hollow transect on an ombrotrophic raised bog in Patagonia, southern Chile. Coupled stable carbon, oxygen and hydrogen isotopic measurements were made on individual samples of Sphagnum moss cellulose and compared with plant-associated waters, local hydrology, temperature and relative humidity, sampled at the same points along the study transect. Results reveal a range of environmental responses, which were supported by plant-physiological models in the case of carbon and oxygen isotopes. For hydrogen isotopes, the results obtained from cellulose indicated a need for further research into hydrogen isotope fractionation in Sphagnum. We recommend conducting site-specific characterization of plant response to support the development of peat-based isotope records for palaeoenvironmental research, and where logistically possible, that monitoring is conducted over timescales appropriate to the time-integrative nature of the Sphagnum record.
