plant macroremains -- the Holocene -- dynamics of forest ecosystems -- paleoclimate

Аннотация: New data on the composition of surface assemblages of plant macroremains from soil and swamp samples have been obtained in the study of geomorphologically different localities in the middle reaches of the Nizhnyaya Tunguska River. The results of paleocarpological analysis of forest soil sections supported by relevant palynological and geochronological data are presented. Natural changes of the forest cover over the past 2400 years and quantitative characteristics of the paleoclimate during each stage are described.

    Tree-ring growth curves as sources of climatic information
[Text] / M. M. Naurzbaev, M. K. Hughes, E. A. Vaganov // Quat. Res. - 2004. - Vol. 62, Is. 2. - P126-133, DOI 10.1016/j.yqres.2004.06.005. - Cited References: 35 . - 8. - ISSN 0033-5894

Аннотация: Regional growth curves (RGCs) have been recently used to provide a new basis for removing nonclimatic trend from tree-ring data. Here we propose a different use for RGCs and explore their properties along two transects, one meridional and the other elevational. RGCs consisting of mean ring width plotted against cambial age were developed for larch samples from 34 sites along a meridional transect (55-72degreesN) in central Siberia, and for 24 sites on an elevational gradient (1120 and 2350 in a.s.l.) in Tuva and neighboring Mongolia at approximately 51degreesN. There are systematic gradients of the parameters of the RGCs, such as I-0-maximum tree-ring width near pith, and I-min, the asymptotic value of tree-ring width in old trees. They are smaller at higher latitude and elevation. Annual mean temperature and mean May-September temperature are highly correlated with latitude here, and hence RGC parameters are correlated with these climatic variables. Correlations with precipitation are more complex, and contradictory between meridional and elevational transects. The presence of a similar gradient in the elevational transect is consistent with temperature being the causal factor for both gradients, rather than, for example, latitude-dependent patterns of seasonal photoperiod change. Taking ring measurements from collections of relict and subfossil wood, the RGC-latitude and RGC-temperature relationships are used to estimate paleo-temperatures on centennial time scales. These estimates are consistent with earlier "traditional" dendroclimatic approaches, and with independent information on the northern extent of forest growth in the early mid-Holocene. It may be possible to use this same approach to make estimates of century-scale paleo-temperatures in other regions where abundant relict wood is present. (C) 2004 Univesity of Washington.

    Forward modeling of regional scale tree-ring patterns in the southeastern United States and the recent influence of summer drought
[Text] / K. J. Anchukaitis [et al.] // Geophys. Res. Lett. - 2006. - Vol. 33, Is. 4. - Ст. L04705, DOI 10.1029/2005GL025050. - Cited References: 29 . - 4. - ISSN 0094-8276

Аннотация: We use a mechanistic model of tree-ring formation to simulate regional patterns of climate-tree growth relationships in the southeastern United States. Modeled chronologies are consistent with actual tree-ring data, demonstrating that our simulations have skill in reproducing broad-scale patterns of the proxy's response to climate variability. The model predicts that a decrease in summer precipitation, associated with a weakening Bermuda High, has become an additional control on tree ring growth during recent decades. A nonlinear response of tree growth to climate variability has implications for the calibration of tree-ring records for paleoclimate reconstructions and the prediction of ecosystem responses to climate change.

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.

    Variability of the air temperature in the North of Eurasia inferred from millennial tree-ring chronologies
/ M. M. Naurzbaev, E. A. Vaganov, O. V. Sidorova // Earth's Cryosphere. - 2003. - Vol. 7, Is. 2. - С. 84-91 . - ISSN 1560-7496
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: Na, Br, Cs, Ca, Mg, Ba, Cl and Br distribution along the profile of peatland in the process of peat accumulation is regulated by the climatic fluctuation during Holocene. The possibility of using this information for paleoclimate reconstruction has been shown. In all probability it can be considered as the biochemical migration of alkali-earth and alkaline metals in the process of peat formation reflects mainly climatic fluctuations, connected with temperature, and halogens - with moistening factor.

    Constructing the tree-ring chronology and reconstructing summertime air temperatures in southern Altai for the last 1500 years
/ V. S. Myglan [et al.] // Geogr. Nat. Resour. - 2012. - Vol. 33, Is. 3. - P200-207, DOI 10.1134/S1875372812030031 . - ISSN 1875-3728
Аннотация: We have constructed and analyzed the 1896-year-long tree-ring chronology for the territory of the Altai Republic. The chronology was based on wood of live trees and remains of trunks of Siberian larch (Larix sibirica Ledeb.) from the upper timberline (2300 m) of the Dzhelo river valley. The chronology agrees well with palaeoclimatic data and reflects the main climatic changes in the northern hemisphere for the last two millennia: an extraordinary decrease in increment after the year 536, "mean secular warming", the "Little Ice Age", and current warming. By calculating the response function between the tree-ring chronology for the Dzhelo and data from weather stations, it was possible to reconstruct the series of June-July air temperature variability for the last 1500 years. The chronology can be used in dating archaeological wood, i. e. in determining the calendar time at which archaeological monuments were constructed. В© 2012 Pleiades Publishing, Ltd.

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: Tree-ring chronologies are widely used to reconstruct high-to low-frequency variations in growing season temperatures over centuries to millennia. The relevance of these timeseries in large-scale climate reconstructions is often determined by the strength of their correlation against instrumental temperature data. However, this single criterion ignores several important quantitative and qualitative characteristics of tree-ring chronologies. Those characteristics are (i) data homogeneity, (ii) sample replication, (iii) growth coherence, (iv) chronology development, and (v) climate signal including the correlation with instrumental data. Based on these 5 characteristics, a reconstruction-scoring scheme is proposed and applied to 39 published, millennial-length temperature reconstructions from Asia, Europe, North America, and the Southern Hemisphere. Results reveal no reconstruction scores highest in every category and each has their own strengths and weaknesses. Reconstructions that perform better overall include N-Scan and Finland from Europe, E-Canada from North America, Yamal and Dzhelo from Asia. Reconstructions performing less well include W-Himalaya and Karakorum from Asia, Tatra and S-Finland from Europe, and Great Basin from North America. By providing a comprehensive set of criteria to evaluate tree-ring chronologies we hope to improve the development of large-scale temperature reconstructions spanning the past millennium. All reconstructions and their corresponding scores are provided at www.blogs.uni-mainz.de/fb09climatology. (C) 2016 Elsevier Ltd. All rights reserved.

Аннотация: Reproducible climate reconstructions of the Common Era (1 CE to present) are key to placing industrial-era warming into the context of natural climatic variability. Here we present a community-sourced database of temperature-sensitive proxy records from the PAGES2k initiative. The database gathers 692 records from 648 locations, including all continental regions and major ocean basins. The records are from trees, ice, sediment, corals, speleothems, documentary evidence, and other archives. They range in length from 50 to 2000 years, with a median of 547 years, while temporal resolution ranges from biweekly to centennial. Nearly half of the proxy time series are significantly correlated with HadCRUT4.2 surface temperature over the period 1850-2014. Global temperature composites show a remarkable degree of coherence between high-and low-resolution archives, with broadly similar patterns across archive types, terrestrial versus marine locations, and screening criteria. The database is suited to investigations of global and regional temperature variability over the Common Era, and is shared in the Linked Paleo Data (LiPD) format, including serializations in Matlab, R and Python. (TABLE) Since the pioneering work of D'Arrigo and Jacoby1-3, as well as Mann et al. 4,5, temperature reconstructions of the Common Era have become a key component of climate assessments6-9. Such reconstructions depend strongly on the composition of the underlying network of climate proxies10, and it is therefore critical for the climate community to have access to a community-vetted, quality-controlled database of temperature-sensitive records stored in a self-describing format. The Past Global Changes (PAGES) 2k consortium, a self-organized, international group of experts, recently assembled such a database, and used it to reconstruct surface temperature over continental-scale regions11 (hereafter, ` PAGES2k-2013'). This data descriptor presents version 2.0.0 of the PAGES2k proxy temperature database (Data Citation 1). It augments the PAGES2k-2013 collection of terrestrial records with marine records assembled by the Ocean2k working group at centennial12 and annual13 time scales. In addition to these previously published data compilations, this version includes substantially more records, extensive new metadata, and validation. Furthermore, the selection criteria for records included in this version are applied more uniformly and transparently across regions, resulting in a more cohesive data product. This data descriptor describes the contents of the database, the criteria for inclusion, and quantifies the relation of each record with instrumental temperature. In addition, the paleotemperature time series are summarized as composites to highlight the most salient decadal-to centennial-scale behaviour of the dataset and check mutual consistency between paleoclimate archives. We provide extensive Matlab code to probe the database-processing, filtering and aggregating it in various ways to investigate temperature variability over the Common Era. The unique approach to data stewardship and code-sharing employed here is designed to enable an unprecedented scale of investigation of the temperature history of the Common Era, by the scientific community and citizen-scientists alike.

    Ranking of tree-ring based hydroclimate reconstructions of the past millennium
/ F. C. Ljungqvist, A. Piermattei, A. Seim [et al.] // Quat. Sci. Rev. - 2020. - Vol. 230. - Ст. 106074, DOI 10.1016/j.quascirev.2019.106074 . - ISSN 0277-3791
Аннотация: To place recent hydroclimate changes, including drought occurrences, in a long-term historical context, tree-ring records serve as an important natural archive. Here, we evaluate 46 millennium-long tree-ring based hydroclimate reconstructions for their Data Homogeneity, Sample Replication, Growth Coherence, Chronology Development, and Climate Signal based on criteria published by Esper et al. (2016) to assess tree-ring based temperature reconstructions. The compilation of 46 individually calibrated site reconstructions includes 37 different tree species and stem from North America (n = 29), Asia (n = 10); Europe (n = 5), northern Africa (n = 1) and southern South America (n = 1). For each criterion, the individual reconstructions were ranked in four groups, and results showed that no reconstruction scores highest or lowest for all analyzed parameters. We find no geographical differences in the overall ranking, but reconstructions from arid and semi-arid environments tend to score highest. A strong and stable hydroclimate signal is found to be of greater importance than a long calibration period. The most challenging trade-off identified is between high continuous sample replications, as well as a well-mixed age class distribution over time, and a good internal growth coherence. Unlike temperature reconstructions, a high proportion of the hydroclimate reconstructions are produced using individual series detrending methods removing centennial-scale variability. By providing a quantitative and objective evaluation of all available tree-ring based hydroclimate reconstructions we hope to boost future improvements in the development of such records and provide practical guidance to secondary users of these reconstructions. © 2019 The Authors

Аннотация: The largest explosive volcanic eruption of the Common Era in terms of estimated sulphur yield to the stratosphere was identified in glaciochemical records 40 years ago, and dates to the mid-thirteenth century. Despite eventual attribution to the Samalas (Rinjani) volcano in Indonesia, the eruption date remains uncertain, and the climate response only partially understood. Seeking a more global perspective on summer surface temperature and hydroclimate change following the eruption, we present an analysis of 249 tree-ring chronologies spanning the thirteenth century and representing all continents except Antarctica. Of the 170 predominantly temperature sensitive high-frequency chronologies, the earliest hints of boreal summer cooling are the growth depressions found at sites in the western US and Canada in 1257 CE. If this response is a result of Samalas, it would be consistent with an eruption window of circa May-July 1257 CE. More widespread summer cooling across the mid-latitudes of North America and Eurasia is pronounced in 1258, while records from Scandinavia and Siberia reveal peak cooling in 1259. In contrast to the marked post-Samalas temperature response at high-elevation sites in the Northern Hemisphere, no strong hydroclimatic anomalies emerge from the 79 precipitation-sensitive chronologies. Although our findings remain spatially biased towards the western US and central Europe, and growth-climate response patterns are not always dominated by a single meteorological factor, this study offers a global proxy framework for the evaluation of paleoclimate model simulations.
