“…This region, like much of the northern high latitudes, is likely to be especially sensitive to warming due to climate change (IPCC, 2007). The classic description of carbon isotope fractionation between plant tissue and the atmosphere (Farquhar et al, 1982(Farquhar et al, , 1989 has been widely used to investigate the physiological response of trees growing within the taiga to climate change (e.g., Robertson et al, 1997;Waterhouse et al, 2000;Buhay et al, 2008;Gagen et al, 2008;Hilasvuori, 2011;Holzk€ amper et al, 2012;Sidorova et al, 2013). Researchers have shown that the d 13 C value measured from successive annual tree-rings reflects changes in the d 13 C value of atmospheric CO 2 (d 13 C CO2 ) and atmospheric CO 2 concentration (pCO 2 ) (McCarroll & Loader, 2004;McCarroll et al, 2009;Schubert & Jahren, 2012) and is modified by changes in stomatal conductance (Warren et al, 2001;Arneth et al, 2002;Leavitt, 2002;McCarroll et al, 2003).…”

The Arctic is particularly sensitive to climate change, but the independent effects of increasing atmospheric CO2 concentration (pCO2 ) and temperature on high-latitude forests are poorly understood. Here, we present a new, annually resolved record of stable carbon isotope (δ(13) C) data determined from Larix cajanderi tree cores collected from far northeastern Siberia in order to investigate the physiological response of these trees to regional warming. The tree-ring record, which extends from 1912 through 1961 (50 years), targets early twentieth-century warming (ETCW), a natural warming event in the 1920s to 1940s that was limited to Northern hemisphere high latitudes. Our data show that net carbon isotope fractionation (Δ(13) C), decreased by 1.7‰ across the ETCW, which is consistent with increased water stress in response to climate warming and dryer soils. To investigate whether this signal is present across the northern boreal forest, we compiled published carbon isotope data from 14 high-latitude sites within Europe, Asia, and North America. The resulting dataset covered the entire twentieth century and spanned both natural ETCW and anthropogenic Late Twentieth-Century Warming (~0.7 °C per decade). After correcting for a ~1‰ increase in Δ(13) C in response to twentieth century pCO2 rise, a significant negative relationship (r = -0.53, P < 0.0001) between the average, annual Δ(13) C values and regional annual temperature anomalies is observed, suggesting a strong control of temperature on the Δ(13) C value of trees growing at high latitudes. We calculate a 17% increase in intrinsic water-use efficiency within these forests across the twentieth century, of which approximately half is attributed to a decrease in stomatal conductance in order to conserve water in response to drying conditions, with the other half being attributed to increasing pCO2 . We conclude that annual tree-ring records from northern high-latitude forests record the effects of climate warming and pCO2 rise across the twentieth century.

“…Tree-ring isotopes, generally in cellulose (see further), are thus potentially useful to reconstruct past climatic conditions with high temporal resolution (Waterhouse et al, 2000;Barbour et al, 2002;Raffalli-Delerce et al, 2004;Danis et al, 2006;Young et al, 2010;Szymczak et al, 2012;Porter et al, 2013). Northeastern Canada is characterized by a very well developed hydrographic network, a heritage of the last glaciation, which constitutes a unique freshwater reserve.…”

“…Since the earliest isotopic dendroclimatology studies conducted in the Arctic (Sonninen and Jungner, 1995;McCarroll and Pawellek, 1998;Waterhouse et al, 2000), several isotope studies have made significant contributions to palaeohydrology 5 (e.g. Waterhouse et al, 2000;Holzkämper et al, 2008;2012;Sidorova et al, 2008;Porter et al, 2009).…”

The combination of long-lived trees, robust dendrochronologies and excellent sample preservation both on land and in lakes have facilitated the development of several multi-centennial to millennial length isotopic records (Boettger et al, 2003;Kremenetski et al, 2004;Sidorova et al, 2008;Young et al, 2010;Gagen et al, 2011;Loader et al, 2013;Porter et al, 2014).…”

Abstract. Along with Arctic amplification, changes in Arctic hydroclimate have become increasingly apparent. Reanalysis data show increasing trends in Arctic temperature and precipitation over the 20 th century, but changes are not homogenous 30 across seasons or space. The observed hydroclimate changes are expected to continue, and possibly accelerate, in the coming century, not only affecting pan-Arctic natural ecosystems and human activities, but also lower latitudes through changes in atmospheric and oceanic circulation. However, a lack of spatiotemporal observational data makes reliable quantification of Arctic hydroclimate change difficult, especially in a long-term context. To understand hydroclimate variability and the mechanisms driving observed changes, beyond the instrumental record, climate proxies are needed. Here we bring together 35 the current understanding of Arctic hydroclimate during the past 2000 years, as inferred from natural archives and proxies and palaeoclimate model simulations. Inadequate proxy data coverage is apparent, with distinct data gaps in most of Eurasia and parts of North America, which makes robust assessments for the whole Arctic currently impossible. Hydroclimate proxies and climate models indicate that the Medieval Climate Anomaly (MCA) was anomalously wet, while conditions Clim.

However, it is clear that there are large regional differences, which are especially evident during the LIA. Due to the spatiotemporal differences in Arctic hydroclimate, we recommend detailed regional studies, e.g. including field reconstructions, to disentangle spatial patterns and potential forcing factors. At present, it is only possible to carry out regional syntheses for a few areas of the Arctic, e.g. Fennoscandia, Greenland and western North America. To fully assess pan-Arctic hydroclimate variability for the last two 5 millennia additional proxy records are required.
