Аннотация: The development of research into the history of tree growth and inferred summer temperature changes in Yamaha spanning the last 2000 years is reviewed. One focus is the evolving production of tree-ring width (TRW) and tree-ring maximum-latewood density (MXD) larch (Larix sibirica) chronologies, incorporating different applications of Regional Curve Standardisation (RCS). Another focus is the comparison of independent data representing past tree growth in adjacent Yamaha areas: Yamal and Polar Urals, and the examination of the evidence for common growth behaviour at different timescales. The sample data we use are far more numerous and cover a longer time-span at Yamal compared to the Polar Urals, but Yamal has only TRW, while there are both TRW and MXD for the Polar Urals. We use more data (sub-fossil and from living trees) than in previous dendroclimatic studies in this region. We develop a new TRW chronology for Yamal, more than 2000 years long and running up to 2005. For the Polar Urals we develop new TRW and MXD chronologies that show good agreement at short (<15 years) and medium (15-100 years) timescales demonstrating the validity of attempts to reconcile the evidence of longer-timescale information that they provide. We use a "conservative" application of the RCS approach (two-curve signal-free RCS), guarding against the possibility of "modern sample bias": a possible inflation of recent chronology values arising out of inadvertent selection of mostly relatively fast-growing trees in recent centuries. We also transform tree indices to have a normal distribution to remove the positive chronology skew often apparent in RCS TRW chronologies. This also reduces the apparent magnitude of 20th century tree-growth levels. There is generally good agreement between all chronologies as regards the major features of the decadal to centennial variability. Low tree-growth periods for which the inferred summer temperatures are approximately 2.5 degrees C below the 1961-90 reference are apparent in the 15-year smoothed reconstructions, centred around 1005, 1300, 1455, 1530, particularly the 1810s where the inferred cooling reaches -4 degrees C or even -6 degrees C for individual years, and the 1880s. These are superimposed on generally cool pre-20th century conditions: the long-term means of the pre-1900 reconstructed temperature anomalies range from -0.6 to -0.9 degrees C in our alternative reconstructions. There are numerous periods of one or two decades with relatively high growth (and inferred summer temperatures close to the 1961-1990 level) but at longer timescales only the 40-year period centred at 250 CE appears comparable with 20th century warmth. Although the central temperature estimate for this period is below that for the recent period, when we take into account the uncertainties we cannot be highly confident that recent warmth has exceeded the temperature of this earlier warm period. While there are clear warm decades either side of 1000 CE, neither TRW nor MXD data support the conclusion that temperatures were exceptionally high during medieval times. One previous version of the Polar Urals TRW chronology is shown here to be in error due to an injudicious application of RCS to non-homogeneous sample data, partly derived from root-collar samples that produce spuriously high chronology values in the 11th and 15th centuries. This biased chronology has been used in a number of recent studies aimed at reconstructing wider scale temperature histories. All of the chronologies we have produced here clearly show a generally high level of growth throughout their most recent 80 years. Allowing for chronology and reconstruction uncertainty, the mean of the last 100 years of the reconstruction is likely warmer than any century in the last 2000 years in this region.

Аннотация: We related tree ring width (TRW) and isotopic composition (delta(13)C, delta(18)O) of wood and cellulose from four larch trees (Larix cajanderi Mayr.) to climate parameters. The material was sampled in northeastern Yakutia [70 degrees N-148 degrees E] for the recent (AD 1880-2004) and early Medieval (AD 900-1000) periods. During the recent period June, July, and August air temperatures were positively correlated with delta(13)C and delta(18)O of wood and cellulose, while July precipitation was negatively correlated. Furthermore, the vapor pressure deficit (VPD) of July and August was significantly correlated with delta(13)C of wood and cellulose, but VPD had almost no influence on delta(18)O. Comparative analyses between mean isotope values for the (AD 900-1000) and (AD 1880-2004) periods indicate similar ranges of climatic conditions, with the exception of the period AD 1950-2004. While isotopic ratios in cellulose are reliably related to climatic variables, during some periods those in whole wood showed even stronger relationships. Strong positive correlations between delta(18)O of cellulose and Greenland ice-core (GISP2) data were detected for the beginning of the Medieval period (r = 0.86; p 0.05), indicating the reliability of isotope signals in tree rings for large-scale reconstructions.

Аннотация: Regional tree ring chronology with extension 2209 years (from 212 B.C. till 1996 A.D.) was built for east Taymir and Putoran according to wood of living trees, well- preserved remains of dead trees, and subfossil wood from alluvial bank deposits by the cross-dating method. In addition, the "floating" tree ring width chronology for the period of Holocene optimum (3300-2600 B.C.) was built with extention 685 years and supported by several radiocarbon dates. High values of synchrony and correlation of individual tree ring series show a prevailing effect of one external factor on radial tree growth change in the studied region of the Siberian subarctic. It was established that the main factors of growth variability are the early summer and annual temperature, which explain up to 70% of tree growth rate variability. Cyclic components stable for two millennia were revealed at analysis of the tree ring chronology: double secular (similar to 180 years), secular (78-90 years), and intrasecular (44, 28, 11, and 6.7-6.9 years) variations. Models for reconstruction of the early summer and annual air temperature were obtained according to tree ring variability. Temperature dynamics in the eastern part of Taymir for the last two millenia agree well with temperature variations in the Northern Hemisphere obtained according to other indirect sources. The warming of the middle of the twentieth century is not extraordinary. The warming at the end of the first and beginning of the second millennia ("Medieval Warm Period") was longer in time and closer in amplitude.

Аннотация: To answer the question "Has the recent warming no analogues in the Siberian north?" we analyzed larch tree samples (. Larix gmelinii Rupr.) from permafrost zone in the eastern Taimyr (TAY) (72В°N, 102В°E) using tree-ring and stable isotope analyses for the Climatic Optimum Period (COP) 4111-3806 BC and Medieval Warm Period (MWP) 917-1150 AD, in comparison to the recent period (RP) 1791-2008 AD.We developed a description of the climatic and environmental changes in the eastern Taimyr using tree-ring width and stable isotope (?13C, ?18O) data based on statistical verification of the relationships to climatic parameters (temperature and precipitation).Additionally, we compared our new tree-ring and stable isotope data sets with earlier published July temperature and precipitation reconstructions inferred from pollen data of the Lama Lake, Taimyr Peninsula, ?18O ice core data from Akademii Nauk ice cap on Severnaya Zemlya (SZ) and ?18O ice core data from Greenland (GISP2), as well as tree-ring width and stable carbon and oxygen isotope data from northeastern Yakutia (YAK).We found that the COP in TAY was warmer and drier compared to the MWP but rather similar to the RP. Our results indicate that the MWP in TAY started earlier and was wetter than in YAK. July precipitation reconstructions obtained from pollen data of the Lama Lake, oxygen isotope data from SZ and our carbon isotopes in tree cellulose agree well and indicate wetter climate conditions during the MWP.Consistent large-scale patterns were reflected in significant links between oxygen isotope data in tree cellulose from TAY and YAK, and oxygen isotope data from SZ and GISP2 during the MWP and the RP.Finally, we showed that the recent warming is not unprecedented in the Siberian north. Similar climate conditions were recorded by tree-rings, stable isotopes, pollen, and ice core data 6000 years ago. В© 2013 Elsevier Ltd.

Аннотация: An integral estimation of tree-ring growth spatial-temporal conjugation was carried out based on tree-ring chronology network of subarctic zone of Siberia, Ural and Scandinavia for the last 2000 years. Phase and amplitude disagreements of the annual growth and its decadal fluctuation in different subarctic sectors of Eurasia are changed by synchronous fluctuation when century and longer growth cycles are considered. Long-term changes of radial growth indicate common character of global climatic changes in subarctic zone of Eurasia. Medieval warming occurred from 10 to 12 centuries and 15-century warming were changed by Little Ice Age with the cooling culmination taking place in the 17 century. Current warming which started at the beginning of the 19th-century for the moment does not exceed the amplitude of the medieval warming. The tree-ring chronologies do not indicate unusually abrupt temperature rise during the last century, which could be reliably associated with greenhouse gas increasing in the atmosphere of our planet. Modem period is characterized by heterogeneity of warming effect in subarctic regions of Eurasia. Integral tree-ring chronology of the Northern Eurasia shows well agreement with 18O fluctuations in the ice core obtained for Greenland (GISP2). В© M.M. Naurzbaev, E.A. Vaganov, O.V. Sidorova, 2003.

Аннотация: Wood material from living trees and trunk remains of Siberian larch (Larix sibirica Ldb) from the upper treeline (2300 m) of the Mongun Taiga mountain massif was used for building up a 2367-year Mongun tree-ring chronology. The chronology is consistent with paleoclimatic data and reflects the main changes in the climate of the Northern Hemisphere over the last two millennia: the cooling of the 6th century, "Medieval warming," "Little Ice Age," and the current warming. The calculation of the response function between the chronology and data from weather stations made it possible to reconstruct the variability of air temperatures in June and July for 2000 years. The chronology contains the climate signal of regional scale and is suitable for dating archaeological wood, that is, for determining the calendar time of building the monuments in the Altai-Sayan region.

Аннотация: For the first time a New 1772-year tree ring width chronology has been built for the Altay Mountain. The living trees and rest of stem wood of Siberian larch (Larix sibirica Ldb) were used from the upper tree line (2300 m) in Gelo valley. This chronology is coincidence with the paleoclimatic data and reflects basic climatic changes in the northern hemisphere for the last two millennia. We revealed extraordinary decreasing of tree radial growth after AD 536, "Medieval warming", "Little Ice Age", and current warming were revealed. The comparative analysis between Gelo and ALT tree ring chronologies has shown a good correlation in tree ring variability while revealing mismatch in response function of June-July air temperature. Such a long term chronology gives the possibility for dating of archeological wood to define the date of construction of archeological monuments.

Аннотация: Newly developed millennial delta C-13 larch tree-ring chronology from Siberia allows reconstruction of summer (July) vapor pressure deficit (VPD) changes in a temperature-limited environment. VPD increased recently, but does not yet exceed the maximum values reconstructed during the Medieval Warm Anomaly. The most humid conditions in the Siberian North were recorded in the Early Medieval Period and during the Little Ice Age. Increasing VPD under elevated air temperature affects the hydrology of these sensitive ecosystems by greater evapotranspiration rates. Further VPD increases will significantly affect Siberian forests most likely leading to drought and forest mortality even under additional access of thawed permafrost water. Adaptation strategies are needed for Siberian forest ecosystems to protect them in a warming world.

Аннотация: Climate reconstructions for the Common Era are compromised by the paucity of annually-resolved and absolutely-dated proxy records prior to medieval times. Where reconstructions are based on combinations of different climate archive types (of varying spatiotemporal resolution, dating uncertainty, record length and predictive skill), it is challenging to estimate past amplitude ranges, disentangle the relative roles of natural and anthropogenic forcing, or probe deeper interrelationships between climate variability and human history. Here, we compile and analyse updated versions of all the existing summer temperature sensitive tree-ring width chronologies from the Northern Hemisphere that span the entire Common Era. We apply a novel ensemble approach to reconstruct extra-tropical summer temperatures from 1 to 2010 CE, and calculate uncertainties at continental to hemispheric scales. Peak warming in the 280s, 990s and 1020s, when volcanic forcing was low, was comparable to modern conditions until 2010 CE. The lowest June–August temperature anomaly in 536 not only marks the beginning of the coldest decade, but also defines the onset of the Late Antique Little Ice Age (LALIA). While prolonged warmth during Roman and medieval times roughly coincides with the tendency towards societal prosperity across much of the North Atlantic/European sector and East Asia, major episodes of volcanically-forced summer cooling often presaged widespread famines, plague outbreaks and political upheavals. Our study reveals a larger amplitude of spatially synchronized summer temperature variation during the first millennium of the Common Era than previously recognised. © 2020 Elsevier GmbH

Аннотация: Recent climate change in Siberia is increasing the probability of dangerous forest fires. The development of effective measures to mitigate and prevent fires is impossible without an understanding of long-term fire dynamics. This paper presents the first multi-site palaeo-fire reconstruction based on macroscopic charcoal data from peat and lake sediment cores located in different landscapes across the permafrost area of central Siberia. The obtained results show similar temporal patterns of charcoal accumulation rates in the cores under study, and near synchronous changes in fire regimes. The paleo-fire record revealed moderate biomass burning between 3.4 and 2.6 ka BP, followed by the period of lower burning occurring from 2.6 to 1.7 ka BP that coincided with regional climate cooling and moistening. Minimal fire activity was also observed during the Little Ice Age (0.7-0.25 ka BP). Fire frequencies increased during the interval from 1.7 to 0.7 ka BP and appears to be partly synchronous with climate warming during the Medieval Climate Anomaly. Regional reconstructions of long-term fire history show that recent fires are unprecedented during the late Holocene, with modern high biomass burning lying outside millennial and centennial variability of the last 3400 years.
