title: NOAA/WDS Paleoclimatology - Porter - Esau Channel Mackenzie Delta - PCGL - ITRDB CANA507

description: We present a reconstruction of June-July minimum temperatures since AD 1245 for the Mackenzie Delta region based on a 29-site network of white spruce (Picea glauca) ring-width series. Most but not all trees experienced a divergent temperature-growth response, similar to the divergence that has affected other white spruce trees across Yukon and Alaska. However, divergence in the study region began as early as AD 1900 and we have documented our methods to avoid including divergent signals in the reconstruction. Calibration/verification testing based on local temperature data, and multi-century coherence with nearby and large-scale temperature proxy records, confirm that our reconstruction is robust. The reconstruction shows cool conditions in the late 13th, early 18th and early 19th centuries, corresponding with solar minima and increased volcanism. These cool periods are interrupted by warm periods consistent with early to mid-20th century warmth. The late 20th century is the warmest interval, and the last decade is estimated to be 1.4C warmer than any decade before the mid-20th century. The reconstructed climate history corroborates other proxy-based inferences and supports the notion that high-latitude regions such as the Mackenzie Delta have experienced rapid warming in recent decades that is exceptional in the last eight centuries.

title: NOAA/WDS Paleoclimatology - Glaciar Frias Tree ring width, PAGES LOTRED-SA Version

description: Millennium-old alerce trees (Fitzroya cupressoides (Mol.)
     Johnst.) have been used to develop a 1120-year reconstruction of the
     summer temperature departures for the Andes of northern Patagonia in
     Argentina. Four main climatic episodes can be distinguished in this
     proxy paleoclimatic record. The first, a cold and moist interval from
     A.D. 900 to 1070, was followed by a warm-dry period from A.D. 1080 to
     1250 correlative with the Medieval warm epoch of Europe. Afterward, a
     long, cold-moist period followed from A.D. 1270 to 1670, peaking around
     A.D. 1340 and 1650. These cold maxima are contemporaneous with two
     principal Little Ice Age events registered in the Northern Hemisphere.
     Warmer conditions then resumed between A.D. 1720 and 1790. These
     episodes are supported by glaciological and palynological data in
     Patagonia. Following a cold period in the early 1800s, tree-ring indices
     have oscillated around the long-term mean, except for a warmer period
     from A.D. 1850 to 1890. Correlations between the Rio Alerce
     reconstruction and the regional weather stations indicate that the
     tree-ring variations are correlated with a homogeneous summer weather
     pattern covering Patagonia east of the Andes from 38° to 50°S.

title: NOAA/WDS Paleoclimatology - Gardar Drift Stable Isotope and Sediment Data since ~300 ka

description: Benthic foraminiferal stable isotopic records from a transect of sediment cores south of the Iceland-Scotland Ridge reveal that the penetration depth of Iceland-Scotland Overflow Water (ISOW) varied on orbital timescales with precessional pacing over the past ~ 200 kyr. Similar, higher benthic foraminiferal d13C values (~ 1.0 ‰) were recorded at all transect sites downstream of the Iceland-Scotland Ridge during interglacial periods (Marine Isotope Chrons 5 and 1), indicating a deeply penetrating ISOW. During glacial periods (Marine Isotope Chrons 6, 4, and 2), benthic foraminiferal d13C values from the deeper (2700-3300 m), southern sites within this transect were significantly lower (~ 0.5 ‰) than values from the northern (shallower) portion of the transect (~ 1.0 ‰), reflecting a shoaling of ISOW and greater influence of glacial Southern Component Water (SCW) in the deep Northeast Atlantic. Particularly during intermediate climate states, ISOW strength is driven by precesional cycles, superimposed on the large-scale glacial-interglacial ISOW variability. Millennial-scale variability in the penetration of ISOW, likely caused by high-frequency Heinrich and Dansgaard-Oeschger Events, is most pronounced during intermediate climate states.

title: NOAA/WDS Paleoclimatology - Gardar Drift Foraminiferal and Sedimentological Data from the Early Holocene and Younger Dryas

description: The transition into the Holocene marks the last large, orbitally derived climatic event and ultimately led to the onset of modern oceanic conditions. The influence of this climatic change on North Atlantic Deep Water (NADW) formation and circulation remains ambiguous. High-resolution records from southern Gardar Drift, south of Iceland, show abrupt decreases in benthic foraminiferal  d13C values at discrete intervals during the early Holocene, suggesting that NADW shoaled episodically. Intervals of lower d13C values are coincident with higher d18ON. pachyderma, d18OG. bulloides and high abundance of lithic grains/g, indicating that these periods also had enhanced surface water stratification due to increased meltwater in the circum-North Atlantic region. Our new planktonic and benthic foraminiferal stable isotopic data show that increased meltwater delivery led to brief reorganizations of deepwater currents. These southern Gardar surface and deep water records indicate that the early Holocene was a period of multiple abrupt climatic events that were propagated to the North Atlantic during the final break up of ice sheets in the Northern Hemisphere and suggests that some component of the residual early Holocene sea level rise can be attributed to Northern Hemispheric sources.

title: NOAA/WDS Paleoclimatology - Paleo-pCO2 Database Middle Eocene Stomata CO2 Data

description: Fossils from Paleogene High Arctic deposits provide some of the clearest evidence for greenhouse climates in the past and offer the potential to improve our understanding of Earth system dynamics in a largely ice-free world. One of the most well-known and stunningly preserved polar forest sites, Napartulik, crops out of middle Eocene (47.9-37.8 Ma) sediments on eastern Axel Heiberg Island, Nunavut, Canada (~78N paleolatitude). An abundance of data from Napartulik suggests mean annual temperatures at least 30C warmer than today and atmospheric water loads 2x current levels. Despite this wealth of paleontological and paleoclimatological data, there are currently no direct constraints on atmospheric CO2 levels for Napartulik or any other polar forest site. Here we apply a new plant gas-exchange model to Metasequoia (dawn redwood) leaves to reconstruct atmospheric CO2 from six fossil forest horizons at Napartulik. Individual reconstructions vary between 392 ppm and 474 ppm, with a site median of 424 ppm (351-523 ppm at 95% confidence). These estimates represent the first direct constraints on CO2 for a High Arctic forest and suggest that the temperate conditions present at Napartulik during the middle Eocene were maintained under CO2 concentrations ~1.5x pre-industrial levels. Our results support the case that long-term climate sensitivity to CO2 in the past was sometimes high, even during largely ice-free periods, highlighting the need to better understand the climate forcings and feedbacks responsible for this amplification.

title: NOAA/WDS Paleoclimatology - Upper Murray, Australia, 300 Year Stochastic Rainfall Reconstructions

description: Estimates of hydrological risk are crucial to enable adequate planning and preparation for extreme events. However, the accurate estimation of hydrological risk is hampered by relatively short instrumental records in many parts of the world. Information derived from climate-sensitive paleoclimate proxies provide an opportunity to resolve hydroclimatic variability, but many regions, such as Australia's Murray-Darling Basin (MDB), currently lack the suitable in situ proxies necessary to do this. Here, new MDB rainfall reconstructions are presented based on a novel method using paleoclimate rainfall proxies in the Australasian region spanning from 749 BCE to 1980 CE. Our results emphasize the need to develop additional reconstructions and, with the companion paper, demonstrate how this information can be used to benefit water resource management. This study shows that prior to the 20th century both dry and wet epochs have persisted for longer periods than observed in the instrumental record - with the probability of both dry and wet periods exceeding a decade at least 10 times more likely prior to 1883 than suggested by the instrumental records. Some reconstructed rainfalls exceeded the instrumental range (i.e. drier dry epochs and wetter wet spells) despite a systematic underestimation of extremes due to a combination of proxy quality and model bias. Importantly, the results demonstrate that the instrumental record does not cover the full range of hydroclimatic variability possible in the MDB. Therefore hydroclimatic risk assessments based on the instrumental record likely underestimate, or at least misinterpret, the frequency, duration and magnitude of wet and dry epochs.

title: NOAA/WDS Paleoclimatology - The seismic-stratigraphic record of lake-level fluctuations in Lake Challa: hydrological stability and change in equatorial East-Africa over the last 140 kyr

description: Seismic-reflection data from crater lake Challa(Mt. Kilimanjaro, equatorial East Africa) reveal a ~210-m thick sedimentary infill containing distinct seismic-stratigraphic signatures of late-Quaternary lake-level fluctuations. Extrapolation of a well-constrained age model on the cored upper part of the sequence suggests that these lake-level fluctuations represent a detailed and continuous record of moisture-balance variation in equatorial East Africa over the last 140 kyr. This record indicates that the most severe aridity occurred during peak Penultimate glaciation immediately before ~128 kyr BP (coeval with Heinrich event 11) and during a Last Interglacial ‘megadrought’ period between ~114 and ~97 kyr BP; in comparison, Last Glacial Maximum (LGM) aridity was modest. It was preceded by ~75 000 years of relatively stable and moist climate conditions interrupted by eleven short-lived dry spells, five of which match the timing of Heinrich events 2 to 6. Climate history near the East African equator reflects variation in the precessional forcing of monsoon rainfall modulated by orbital eccentricity, but precession-driven moisture fluctuations were less extreme than those observed in northern and southern tropical Africa. The near-continuous moist climate from ~97 to 20.5 kyr BP recorded in the Lake Challa record contrasts with the trend towards greater aridity after ~70 kyr BP documented in equatorial West Africa. This long period of moist glacial climate and a short, relatively modest LGM drought can be attributed to greater independence of western Indian Ocean monsoon dynamics from northern high-latitude glaciation than those in the tropical Atlantic Ocean. This rather persistent moist glacial climate regime may have helped maintain high biodiversity in the tropical forest ecosystems of the Eastern Arc mountains in Tanzania.
