title: NOAA/WDS Paleoclimatology - Paleo-pCO2 Database ODP1264 5 Million Year Boron Isotope and CO2 Data

description: During the past five million yrs, benthic d18O records indicate a large range of climates, from warmer than today during the Pliocene Warm Period to considerably colder during glacials. Antarctic ice cores have revealed Pleistocene glacial-interglacial CO2 variability of 60-100 ppm, while sea level fluctuations of typically 125 m are documented by proxy data. However, in the pre-ice core period, CO2 and sea level proxy data are scarce and there is disagreement between different proxies and different records of the same proxy. This hampers comprehensive understanding of the long-term relations between CO2, sea level and climate. Here, we drive a coupled climate-ice sheet model over the past five million years, inversely forced by a stacked benthic d18O record. We obtain continuous simulations of benthic d18O, sea level and CO2 that are mutually consistent. Our model shows CO2 concentrations of 300 to 470 ppm during the Early Pliocene. Furthermore, we simulate strong CO2 variability during the Pliocene and Early Pleistocene. These features are broadly supported by existing and new d11B-based proxy CO2 data, but less by alkenone-based records. The simulated concentrations and variations therein are larger than expected from global mean temperature changes. Our findings thus suggest a smaller Earth System Sensitivity than previously thought. This is explained by a more restricted role of land ice variability in the Pliocene. The largest uncertainty in our simulation arises from the mass balance formulation of East Antarctica, which governs the variability in sea level, but only modestly affects the modeled CO2 concentrations.

title: NOAA/WDS Paleoclimatology - Western North America LGM Ensemble Hydroclimatic Reconstructions

description: The hydroclimate history of North America includes the formation and desiccation of large inland lakes and the growth and ablation of glaciers throughout the Quaternary period. At the Last Glacial Maximum, expanded pluvial lakes in the south and aridity in the northwest suggest that the winter westerly storm track was displaced southwards and migrated northwards as the Laurentide Ice Sheet waned. However, lake highstands do not occur synchronously along zonal bands, in  conflict with this hypothesis. Here we compile a network of precipitation proxy reconstructions from lakes, speleothems, groundwater deposits, pack rat middens and glaciers from the western and southwestern US, which we compare with an ensemble of climate simulations to identify the controls  of regional hydroclimatic change. The proxy records suggest a precipitation dipole during the Last Glacial Maximum, with wetter than modern conditions in the southwest and drier conditions near the ice sheet, and a northwest-southeast trending transition zone across the northern Great Basin. The models that simulate a weaker and south-shifted Aleutian low-pressure system, a strong North Pacific high-pressure system, and a high above the ice sheet best reproduce this regional variation. We therefore conclude that rather than a uniformly south-shifted storm track, a stronger jet that is squeezed and steered across the continent by high-pressure systems best explains the observed regional hydroclimate patterns of the Last Glacial Maximum.

title: NOAA/WDS Paleoclimatology - Pliocene-Pleistocene Benthic Foraminiferal Stable Isotope Data from the Southeast Atlantic

description: We present new orbital-resolution Pliocene-Pleistocene benthic stable oxygen isotope (δ18Ob) records from Ocean Drilling Program Sites 1264 and 1267, from Walvis Ridge in the Southeast Atlantic. We compare long-term (>250 kyr) interbasin δ18Ob-gradients between Pacific and North Atlantic regional stacks, as well as intra and interbasin gradients from the perspective of Walvis Ridge. The δ18Ob values from Sites 1264 and 1267 are almost always higher than deep North Atlantic and Pacific sites, with large gradients (>0.5‰) emerging abruptly at ∼2.4 Ma and persisting until ∼1.3 Ma. From this, we infer the presence of a new water mass, which resulted from the influence of dense, 18O-enriched Nordic sea overflow waters via the abyssal East Atlantic. Meanwhile, long-term average δ18Ob values in the North Atlantic appear to have remained within 0–0.25‰ lower than in the Pacific. However, the magnitude of this difference is sensitive to the inclusion of records from the equatorial West Atlantic. These results, together with constraints based on temperature, salinity, and density, suggest an influence of the seawater δ18O (δ18OSW) versus salinity relationship of source waters on δ18Ob values within the Atlantic. In particular, the abrupt emergence at ∼2.4 Ma of higher δ18Ob values at Sites 1264 and 1267, relative to North Atlantic records, appears to require a low-latitude surface water δ18OSW signal. This implies a connection between northward heat transport and deep water export into the abyssal East Atlantic. Hence, our results have implications for the interpretation of δ18Ob records and highlight the potential for δ18Ob to constrain deep Atlantic water mass sources and pathways during the Plio-Pleistocene.

title: NOAA/WDS Paleoclimatology - Puruogangri Ice Cap, China 500 Year Trace Element Data

description: A ~ 500-year section of ice core (1497-1992) from the Puruogangri ice cap has been analyzed at high resolution for 28 trace elements (TEs: Ag, Al, As, Ba, Bi, Cd, Co, Cr, Cs, Cu, Fe, Ga, Li, Mg, Mn, Na, Nb, Ni, Pb, Rb, Sb, Sn, Sr, Ti, Tl, U, V and Zn) to assess different atmospheric contributions to the ice and provide a temporal perspective on the diverse atmospheric influences over the central Tibetan Plateau (TP). At least two volcanic depositions have significantly impacted the central TP over the past 500 years, possibly originating from the Billy Mitchell (1580, Papua New Guinea) and the Parker Peak (1641, Philippines) eruptions. A decreasing aeolian dust input to the ice cap allowed the detection of an atmospheric pollution signal. The anthropogenic pollution contribution emerges in the record since the early 1900s (for Sb and Cd) and increases substantially after 1935 (for Ag, Zn, Pb, Cd and Sb). The metallurgy (Zn, Pb and steel smelting) emission products (Cd, Zn, Pb and Ag) from the former Soviet Union and especially from central Asia (e.g., Kyrgyzstan, Kazakhstan) likely enhanced the anthropogenic deposition to the Puruogangri ice cap between 1935 and 1980, suggesting that the westerlies served as a conveyor of atmospheric pollution to central Tibet. The impact of this industrial pollution cumulated with that of the hemispheric coal and gasoline combustion which are respectively traced by Sb and Pb enrichment in the ice. The Chinese steel production accompanying the Great Leap Forward (1958-1961) and the Chinese Cultural Revolution (1966-1976) is proposed as a secondary but proximal source of Pb pollution affecting the ice cap between 1958 and 1976. The most recent decade (1980-1992) of the enrichment time series suggests that Puruogangri ice cap recorded the early Sb, Cd, Zn, Pb and Ag pollution originating from developing countries of South (i.e., India) and East (i.e., China) Asia and transported by the summer monsoonal circulation.

title: NOAA/WDS Paleoclimatology - Eastern Finland Late Holocene Lake Level Reconstructions

description: Long-term paleoclimatic records are needed for understanding natural variability in the context of climate change. Two lake sediment cores were collected from eastern Finland from sites considered sensitive for precipitation and temperature, respectively, over the last ~3000 yr. The paleoclimatic reconstructions based on fossil Chironomidae (Insecta: Diptera) assemblages were considered against a North Atlantic Oscillation (NAO) reconstruction to disentangle possible forcing mechanisms. Generally low effective precipitation was reconstructed between ~3000 and 1500 cal yr BP (calibrated years before present). A distinct stream flow event occurred between ~2400 and 2200 cal yr BP, and the highest effective precipitation occurred ~1300 cal yr BP. The Medieval Climate Anomaly (MCA) between ~1200 and 800 cal yr BP was dry, but the Little Ice Age (LIA) between ~700 and 200 cal yr BP had fluctuating precipitation. The temperature reconstruction depicted a late Holocene cooling trend, which ended at ~1300 cal yr BP when the warm MCA began. The MCA was followed by the cold LIA and the last 100 yr have been characterized by rapid warming. Present temperatures are higher than during any time period of the late Holocene. A general trend of positive NAO mode with elevated summer temperatures and dry hydroclimatic conditions prevailed during the MCA and a negative mode with reduced temperatures during the LIA. However, the NAO-hydroclimate relationship over eastern Scandinavia was not straightforward during the LIA, which varied in moisture dynamics. The records from this present study provide a unique climate archive from the crossing point of southern and northern and eastern and western air masses.

title: NOAA/WDS Paleoclimatology - Yocom fire data from Musgoso, Sierra Madre Oriental, Coahuila, Mexico - IMPD MXMU-001

description: We investigated the influence of broad- v. fine-scale factors on fire in an unusual landscape suitable for distinguishing the drivers of fire synchrony. Our study was conducted in the Sierra Madre Oriental mountain range, in north-eastern Mexico. We worked in nine sites on three parallel mountains that receive nearly identical broad-scale climatic influence, but between which fires are unlikely to spread. We collected and cross dated samples from 357 fire-scarred trees in nine sites in high-elevation mixed-conifer forests and identified fire dates. We used Jaccard similarity analysis to evaluate synchrony among sites and quantified relationships between climate and fire occurrence. Fires were historically frequent (mean fire interval ranged from 8 to 16 years in all sites) and dates of fire exclusion ranged from 1887 to 1962. We found low fire synchrony among the three mountains, indicating a strong influence of fine-scale factors on fire occurrence. Fire regime attributes were similar across mountains despite the independence of fire dates. La Niña events were associated with fire over time, although not significantly since the 1830s. Our results highlight the importance of scale in describing fire regimes and suggest that we can use fire history to understand controls on complex ecosystem processes and patterns.
description: This site was sampled as part of a project to reconstruct historical fire regimes in northeastern Mexico. Ring-boundary fire scars were assigned to the subsequent calendar year.

Fire History Graphs: Fire History Graphs illustrate specific years when fires occurred and how many trees were scarred. They are available in both PDF and PNG formats. The graphs consist of 2 parts, both of which show the X axis (time line) at the bottom with the earliest year of information on the left and the latest on the right. The Fire Index Plot is the topmost plot, and shows two variables: sample depth (the number of recording trees in each year) as a blue line along the left Y axis, compared with the percent trees scarred shown as gray bars along the right Y axis. Below, the Fire Chronology Plot consists of horizontal lines representing injuries by year on individual sampled trees. Symbols are overlain that denote the years containing the dendrochronologically-dated fire scars or injuries. The sample ID of each tree is displayed to the right of each line. The Composite Axis below represents the composite information from all individual series. The symbols used to represent the fire scars or injuries, and the filters used to determine the composite information, are shown in the legend. These graphs were created using the Fire History Analysis and Exploration System (FHAES). See http://www.fhaes.org for more information.

title: NOAA/WDS Paleoclimatology - European Mean and Spatial Summer Temperature Reconstructions Since Roman Times

description: The spatial context is critical when assessing present-day climate anomalies, attributing them to potential forcings and making statements regarding their frequency and severity in a long-term perspective. Recent international initiatives have expanded the number of high-quality proxy-records and developed new statistical reconstruction methods. These advances allow more rigorous regional past temperature reconstructions and, in turn, the possibility of evaluating climate models on policy-relevant, spatio-temporal scales. Here we provide a new proxy-based, annually-resolved, spatial reconstruction of the European summer (June-August) temperature fields back to 755 CE based on Bayesian hierarchical modelling (BHM), together with estimates of the European mean temperature variation since 138 BCE based on BHM and composite-plus-scaling (CPS). Our reconstructions compare well with independent instrumental and proxy-based temperature estimates, but suggest a larger amplitude in summer temperature variability than previously reported. Both CPS and BHM reconstructions indicate that the mean 20th century European summer temperature was not significantly different from some earlier centuries, including the 1st, 2nd, 8th and 10th centuries CE. The 1st century (in BHM also the 10th century) may even have been slightly warmer than the 20th century, but the difference is not statistically significant. Comparing each 50 yr period with the 1951-2000 period reveals a similar pattern. Recent summers, however, have been unusually warm in the context of the last two millennia and there are no 30 yr periods in either reconstruction that exceed the mean average European summer temperature of the last 3 decades (1986-2015 CE). A comparison with an ensemble of climate model simulations suggests that the reconstructed European summer temperature variability over the period 850-2000 CE reflects changes in both internal variability and external forcing on multi-decadal time-scales. For pan-European temperatures we find slightly better agreement between the reconstruction and the model simulations with high-end estimates for total solar irradiance. Temperature differences between the medieval period, the recent period and the Little Ice Age are larger in the reconstructions than the simulations. This may indicate inflated variability of the reconstructions, a lack of sensitivity and processes to changes in external forcing on the simulated European climate and/or an underestimation of internal variability on centennial and longer time scales.

title: NOAA/WDS Paleoclimatology - ITASE-2000-1 Antarctic Ice Core 330 Year Oxygen Isotope Data

description: Changes in atmospheric circulation over the past five decades have enhanced the wind-driven inflow of warm ocean water onto the Antarctic continental shelf, where it melts ice shelves from below. Atmospheric circulation changes have also caused rapid warming over the West Antarctic Ice Sheet, and contributed to declining sea-ice cover in the adjacent Amundsen-Bellingshausen seas. It is unknown whether these changes are part of a longer-term trend. Here, we use water-isotope (d18O) data from an array of ice-core records to place recent West Antarctic climate changes in the context of the past two millennia. We find that the d18O of West Antarctic precipitation has increased significantly in the past 50 years, in parallel with the trend in temperature, and was probably more elevated during the 1990s than at any other time during the past 200 years. However, d18O anomalies comparable to those of recent decades occur about 1% of the time over the past 2,000 years. General circulation model simulations suggest that recent trends in d18O and climate in West Antarctica cannot be distinguished from decadal variability that originates in the tropics. We conclude that the uncertain trajectory of tropical climate variability represents a significant source of uncertainty in projections of West Antarctic climate and ice-sheet change.

title: NOAA/WDS Paleoclimatology - Abbott Lake, California 1,400 Year Sediment Physical Properties Data

description: Abbott Lake (Monterey County, California) is one of only a few natural, permanent lakes located in coastal central California. As a result, it represents an important site for assessing spatiotemporal patterns of past hydroclimatic variability. Combined sedimentologic and isotopic analyses are used to describe 1400 years of hydrologic variability within the lake and its drainage basin. Specifically, changes in sand content, percent total organic matter, and d18O(G. parvus) values suggest changes in paleo-runoff, depositional environment, and relative d18O(lake water) values, respectively. Nine AMS 14C dates on discrete organic material provide age control with a basal age estimate of ~2400 cal years BP. However, we focus on the most recent 1400 years where the age model is most robust. The results indicate that coastal central California was relatively dry (less runoff) during the Medieval Climatic Anomaly (MCA) and variably wet (more runoff) during the Little Ice Age (LIA). These results are compared to Zaca Lake (Kirby et al. 2014) and Lake Elsinore (Kirby et al. 2010), both located south of Abbott Lake, and to flood event layers from Santa Barbara Basin (Hendy et al. 2013). All three sites, including SBB's flood event history, indicate a variably wet LIA and dry MCA; however, the absolute timing of wet and dry episodes is more congruent between Zaca and Elsinore than to Abbott Lake suggesting real spatiotemporal variability along the southern to central California coast. Finally, Abbott Lake is compared to Pacific Decadal Oscillation and Pacific sea surface temperature reconstructions. These comparisons suggest a Pacific-sourced control on late Holocene hydroclimates along coastal central California.
