  • A Common Era Tree-Ring Chronology Sensitive to Cool-Season Temperatures for the Southern Hemisphere

    Kathryn Allen, Edward R Cook et al.•ARTICLE•Tree-Ring Research•2025

    Annually resolved multi-millennial records of temperature are rare in the Southern Hemisphere (SH), and even rarer are SH records of cool-season temperature. Here we present a new tree-ring chronology extending back to 42 BCE based on Athrotaxis selaginoides from southern Tasmania. The development of this chronology was complicated by multiple tree-age cohorts and growth classes. Additionally, there was a collapse in sample depth between the mid-…

  • The Moderating Effect of Mental Health on the Relationship Between Cardiovascular Disease Awareness and Health Behaviors of Middle-Aged Korean Chinese Workers With Cardiovascular Risk Factors in Korea

    Open Access•Rob Wilson, Yu Zhu Zhang et al.•ARTICLE•Journal of Transcultural Nursing•2023

    Understanding relationships between CVD awareness, socioculturally mediated health behaviors, and mental health issues is critical to CVD prevention among participants; moreover, mental health should be specifically assessed and targeted for improvement

  • Examining past and projecting future

    Open Access•Philippa Higgins, Jonathan Palmer et al.•ARTICLE•Environmental Research Letters•2023

    Managing water security and sustaining ecosystem functions under future warming poses substantial challenges for semi-arid regions. The Murray–Darling Basin (MDB) is particularly vulnerable given the considerable demand for water that underpins Australia’s agricultural production and contribution to the national economy. Understanding future drought risk requires a robust assessment of natural variability in drought length, frequency, and magnitu…

  • The feasibility of reconstructing hydroclimate over West Africa using tree-ring chronologies in the Mediterranean region

    Open Access•Boniface Fosu, Edward R Cook et al.•ARTICLE•Environmental Research Letters•2022

    Dendrochronology in West Africa has not yet been developed despite encouraging reports suggesting the potential for long tree-ring reconstructions of hydroclimate in the tropics. This paper shows that even in the absence of local tree chronologies, it is possible to reconstruct the hydroclimate of a region using remote tree rings. We present the West Sub-Saharan Drought Atlas (WSDA), a new paleoclimatic reconstruction of West African hydroclimate…

  • Placing the east-west North American aridity gradient in a multi-century context

    Open Access•Daniel A Bishop, Park Williams et al.•ARTICLE•Environmental Research Letters•2021

    Instrumental records indicate a century-long trend towards drying over western North America and wetting over eastern North America. A continuation of these trends into the future would have significant hydroclimatic and socioeconomic consequences in both the semi-arid Southwest and humid East. Using tree-ring reconstructions and hydrologic simulations of summer soil moisture, we evaluate and contextualize the modern summer aridity gradient withi…

  • Snowpack signals in North American tree rings

    Open Access•Bethany Coulthard, Bethany L Coulthard et al.•ARTICLE•Environmental Research Letters•2020

    Climate change has contributed to recent declines in mountain snowpack and earlier runoff, which in turn have intensified hydrological droughts in western North America. Climate model projections suggest that continued and severe snowpack reductions are expected over the 21st century, with profound consequences for ecosystems and human welfare. Yet the current understanding of trends and variability in mountain snowpack is limited by the relative…

  • Meteorological Factors Associated With Frost Rings in Rocky Mountain Bristlecone Pine at Mt. Goliath, Colorado

    Ana Carolina Maioli Campos Barbosa, Ana Carolina Barbosa et al.•ARTICLE•Tree-Ring Research•2019

    The meteorological factors involved in the formation of earlywood frost rings in Rocky Mountain bristlecone pine (Pinus aristata) have not been described in detail. This study used 51 tree-ring dated Rocky Mountain bristlecone pine trees growing at ca. 3500 m a.s.l. on Mt. Goliath, Colorado, to develop earlywood and latewood frost ring chronologies dating from 1930 to 2010 for investigation of the regional and large-scale weather anomalies respon…

  • The potential to strengthen temperature reconstructions in ecoregions with limited tree line using a multispecies approach

    Open Access•M Ross Alexander, Jessie K Pearl et al.•ARTICLE•Quaternary Research•2019

    Tree-ring reconstructions of temperature often target trees at altitudinal or latitudinal tree line where annual growth is broadly expected to be limited by and respond to temperature variability. Based on this principal, regions with sparse tree line would seem to be restricted in their potential to reconstruct past temperatures. In the northeastern United States, there are only two published temperature reconstructions. Previous work in the reg…

  • European warm-season temperature and hydroclimate since 850 CE

    Open Access•Fredrik Charpentier Ljungqvist, Andrea Seim et al.•ARTICLE•Environmental Research Letters•2019

    The long-term relationship between temperature and hydroclimate has remained uncertain due to the short length of instrumental measurements and inconsistent results from climate model simulations. This lack of understanding is particularly critical with regard to projected drought and flood risks. Here we assess warm-season co-variability patterns between temperature and hydroclimate over Europe back to 850 CE using instrumental measurements, tre…

  • Improved dendroclimatic calibration using blue intensity in the southern Yukon

    Open Access•Rob Wilson, Kevin J Anchukaitis et al.•ARTICLE•The Holocene•2019•Citada por: 1•Referencias: 5

    In north-western North America, the so-called divergence problem (DP) is expressed in tree ring width (RW) as an unstable temperature signal in recent decades. Maximum latewood density (MXD), from the same region, shows minimal evidence of DP. While MXD is a superior proxy for summer temperatures, there are very few long MXD records from North America. Latewood blue intensity (LWB) measures similar wood properties as MXD, expresses a similar clim…

  • South American Dendroecological Fieldweek 2016

  • Ensemble Empirical Mode Decomposition as an Alternative for Tree-Ring Chronology Development

    Open Access•Biing T Guan, William E Wright et al.•ARTICLE•Tree-Ring Research•2018

    Since its establishment, tree-ring analysis has benefitted several scientific fields. Because of its many advantages, dendrochronology is a first choice to reconstruct past environmental variability. Two major concerns about the current tree-ring reconstruction paradigm are the subjective choices of detrending functions and the lack of fidelity to data of chronology generation methods. It is difficult to recover the original tree-ring data once t…

  • Lack of cool, not warm, extremes distinguishes late 20th Century climate in 979-year Tasmanian summer temperature reconstruction

    Open Access•Kathryn Allen, Edward R Cook et al.•ARTICLE•Environmental Research Letters•2018

    Very few annually resolved millennial-length temperature reconstructions exist for the Southern Hemisphere. Here we present four 979-year reconstructions for southeastern Australia for the austral summer months of December–February. Two of the reconstructions are based on the Australian Water Availability Project dataset and two on the Berkeley Earth Surface Temperature dataset. For each climate data set, one reconstruction is based solely on Lag…

    Open Access•Timothy J Osborn, P D Jones et al.•ARTICLE•The Holocene•2018•Referencias: 11

    Keith R Briffa was one of the most influential palaeoclimatologists of the last 30 years. His primary research interests lay in Late-Holocene climate change with a geographical emphasis on northern Eurasia. His greatest impact was in the field of dendroclimatology, a field that he helped to shape. His contributions have been seminal to the development of sound methods for tree-ring analysis and in their proper application to allow the interpretat…

  • Environmental Stress and Steppe Nomads

    Nicola Di Cosmo, Amy Hessl et al.•ARTICLE•The Journal of Interdisciplinary…•2018•Citada por: 2•Referencias: 34

    Newly available paleoclimate data and a re-evaluation of the historical and archaeological evidence regarding the Uyghur Empire (744-840)-one of several nomadic empires to emerge on the Inner Asian steppe-suggests that the assumption of a direct causal link between drought and the stability of nomadic societies is not always justified. The fact that a severe drought lasting nearly seven decades did not cause the Uyghur Empire to collapse, to wage…

  • Potential for tree rings to reveal spatial patterns of past drought variability across western Australia

    Open Access•Alison J O’Donnell, Edward R Cook et al.•ARTICLE•Environmental Research Letters•2017

    Proxy records have provided major insights into the variability of past climates over long timescales. However, for much of the Southern Hemisphere, the ability to identify spatial patterns of past climatic variability is constrained by the sparse distribution of proxy records. This is particularly true for mainland Australia, where relatively few proxy records are located. Here, we (1) assess the potential to use existing proxy records in the Au…

  • Synchronous multi-decadal climate variability of the whole Pacific areas revealed in tree rings since 1567

    Open Access•Keyan Fang, Edward R Cook et al.•ARTICLE•Environmental Research Letters•2017

    Oceanic and atmospheric patterns play a crucial role in modulating climate variability from interannual to multi-decadal timescales by causing large-scale co-varying climate changes. The brevity of the existing instrumental records hinders the ability to recognize climate patterns before the industrial era, which can be alleviated using proxies. Unfortunately, proxy based reconstructions of oceanic and atmospheric modes of the past millennia ofte…

  • The Relationship Between Earlywood and Latewood Ring-Growth Across North America

    Max C A Torbenson, D W Stahle et al.•ARTICLE•Tree-Ring Research•2016

    The relationship between earlywood width (EW) and latewood width (LW) is investigated using 197 tree-ring collections representing several tree species from across the North American continent. Chronologies of LW have limited paleoclimate value when they have low variance or very high correlation with EW from the same site. The correlation of LW and EW can be removed by taking the residuals from linear regression to provide a chronology of discre…

  • North American megadroughts in the Common Era

    During the Medieval Climate Anomaly ( MCA ), Western North America experienced episodes of intense aridity that persisted for multiple decades or longer. These megadroughts are well documented in many proxy records, but the causal mechanisms are poorly understood. General circulation models ( GCMs ) simulate megadroughts, but do not reproduce the temporal clustering of events during the MCA , suggesting they are not caused by the time history of …

    A brief and personal history of the development of dendrochronology in the Hudson Valley of New York in the 1970s and the quantitative reconstruction of climate from tree rings there is provided. Two people stand out in allowing that to happen. Marvin Stokes at the Laboratory of Tree-Ring Research sparked within me a deep and enduring interest in dendrochronology, and Daniel Smiley of Mohonk supported my interest in pursuing tree-ring research in…

  • Dendrochronological Dating of the World Trade Center Ship, Lower Manhattan, New York City

    On July 2010, archaeologists monitoring excavation at the World Trade Center site (WTC) in Lower Manhattan found the remains of a portion of a ship's hull. Because the date of construction and origin of the timbers were unknown, samples from different parts of the ship were taken for dendrochronological dating and provenancing. After developing a 280-year long floating chronology from 19 samples of the white oak group (Quercus section Leucobalanu…

  • The 'segment length curse' in long tree-ring chronology development for palaeoclimatic studies

    Open Access•Edward R Cook, Keith R Briffa et al.•ARTICLE•The Holocene•1995•Citada por: 39

    The problem of constructing millennia-long tree-ring chronologies from overlapping segments of cross-dated ring-width series is reviewed, with an emphasis on preserving very low-frequency signals potentially due to climate. In so doing, a fundamental statistical problem coined the 'segment length curse' is introduced. This 'curse' is related to the fact that the maximum wavelength of recoverable climatic information is ordinarily related to the l…

  • Calculating unbiased tree-ring indices for the study of climatic and environmental change

    Open Access•Edward R Cook, Kenneth E Peters et al.•ARTICLE•The Holocene•1997•Citada por: 10•Referencias: 2

    In dendroclimatology, tree-ring indices are traditionally calculated as part of the tree-ring chronology development process. This is accomplished by fitting a growth curve to the ring-width series and using it as a series of expectations for more or less well specified null conditions (uniform climate perhaps) of annual radial growth. The ratio of the actual ring widths to these expectations produces a set of dimensionless indices that can be av…

    Tree-ring records, six from eastern North America and four from northwestern Europe, are used to develop the first reconstruction of the winter North Atlantic Oscillation (NAO). The reconstructed series spans the interval AD 1701-1980 and explains 41%, of the variance in the NAO over the AD 1874-1980 calibration period. The reconstruction also captures the spectral properties of this index, suggesting that the oscillatory character of the NAO is …

    Tree-ring widths from millennium-old Huon pine (Lagarostrobos franklinii) trees have been used to reconstruct warm season (November-April) temperatures back to AD 900 for Tasmania. The reconstruction indicates that the most recent 100 years of climate have been highly unusual, with the coldest and warmest 25-year periods occurring from 1890 to 1914 and 1965 to 1989, respectively. Although the most recent 25-year period is warmer than any comparab…

    The “hydraulic city” of Angkor, the capitol of the Khmer Empire in Cambodia, experienced decades-long drought interspersed with intense monsoons in the fourteenth and fifteenth centuries that, in combination with other factors, contributed to its eventual demise. The climatic evidence comes from a seven-and-a-half century robust hydroclimate reconstruction from tropical southern Vietnamese tree rings. The Angkor droughts were of a duration and se…

  • Megadroughts in North America

    Open Access•Edward R Cook, Robin Seager et al.•ARTICLE•Journal of Quaternary Science•2010

    IPCC Assessment Report 4 model projections suggest that the subtropical dry zones of the world will both dry and expand poleward in the future due to greenhouse warming. The US Southwest is particularly vulnerable in this regard and model projections indicate a progressive drying there out to the end of the 21st century. At the same time, the USA has been in a state of drought over much of the West for about 10 years now. While severe, this turn …

  • The seasonality of precipitation signals embedded within the North American Drought Atlas

    Open Access•Scott St George, David M Meko et al.•ARTICLE•The Holocene•2010•Citada por: 3•Referencias: 1

    We examine how the seasonality of precipitation signals embedded within the North American Drought Atlas varies across the continent. Instrumental records of average summer (JJA) Palmer Drought Severity Index (PDSI) are characterized by major regional differences in the relative importance of precipitation during summer and winter (DJF). The Atlas, which is based on a network of drought-sensitive tree-ring records, is able to reproduce the main g…

  • Reply to Comments of Nolan and Cook

    Open Access•Larry V Benson, Larry Benson et al.•ARTICLE•American Antiquity•2010•Referencias: 3

    The following reply to the comments by Nolan and Cook makes the following points. The Palmer Drought Severity Index (PDSI) is not a measure of summer rainfall. Cahokia's "Big Bang" dates to the end of the Edelhardt phase and continued through the Lohmann phase. The "American Bottom" refers only to the Mississippi River floodplain in the vicinity of East St. Louis, and the exact nature of human response to climate change cannot be predicted from P…

  • Climate Change during and after the Roman Empire

    Michael Mccormick, Ulf Büntgen et al.•ARTICLE•The Journal of Interdisciplinary…•2012•Citada por: 45•Referencias: 39

    Growing scientific evidence from modern climate science is loaded with implications for the environmental history of the Roman Empire and its successor societies. The written and archaeological evidence, although richer than commonly realized, is unevenly distributed over time and space. A first synthesis of what the written records and multiple natural archives (multi-proxy data) indicate about climate change and variability across western Euras…

  • Megadroughts, Enso, and the Invasion of Late-Roman Europe by the Huns and Avars

    Edward R Cook•CHAPTER•Ancient Mediterranean Environment…•2013

    In this chapter the author argues that prolonged periods of drought may have contributed to the migration of the Huns and Avars westward into Europe during late-Roman times. It investigates the long-range teleconnection between the tropical Pacific Ocean El Nino-Southern Oscillation (ENSO) system and central Asian climate as a possible contributor to the development of droughts there. The evidence presented in the chapter suggests that climate ma…
