title: NOAA/WDS Paleoclimatology - Jennings Cave, Florida, USA d13C cave sediment Data from -984 to 2007 CE

description: Little is known about the potential of organic substances found within cave sediments to provide useful reconstructions of past climatic changes. Here, we present a study of the carbon isotopes of fulvic acids extracted from sediments from a cave in west-central Florida. Fulvic acids are the most contemporaneous representation of soil humic substances derived from vegetation growing above the cave. Radiocarbon dating of these sediments constrains their depositional period to be late-Holocene. The range of the fulvic acid δ13C record shows the dominance of C3 vegetation during this period, but with changes in abundance and the shifting presence of C4 plants. The δ13C values record both the Little Ice Age and Medieval Climate Anomaly which produce drier and wetter conditions for Florida, respectively. Our conclusion that the stable carbon isotopic values of the cave sediment record as a proxy for vegetation change as driven by variability in precipitation is strongly supported by a comparison with the δ13C and δ18O values of two uranium-series dated speleothems from this part of Florida, with both being proxies for precipitation change.

title: NOAA/WDS Paleoclimatology - Southern Annular Mode 1,000 Year Reconstructions

description: The Southern Annular Mode (SAM) is the leading mode of atmospheric interannual variability in the Southern Hemisphere (SH) extra-tropics. Here, we assess the stationarity of SAM spatial correlations with instrumental and paleoclimate proxy data for the past millennium. The instrumental period shows that temporal non-stationarities in SAM teleconnections are not consistent across the SH land areas. This suggests that the influence of the SAM index is modulated by regional effects. However, within key-regions with good proxy data coverage (South America, Tasmania, New Zealand), teleconnections are mostly stationary over the instrumental period. Using different stationarity criteria for proxy record selection, we provide new austral summer and annual mean SAM index reconstructions over the last millennium. Our summer SAM reconstructions are very robust to changes in proxy record selection and the selection of the calibration period, particularly on the multi-decadal timescale. In contrast, the weaker performance and lower agreement in the annual mean SAM reconstructions point towards changing teleconnection patterns that may be particularly important outside the summer months. Our results clearly portend that the temporal stationarity of the proxy-climate relationships should be taken into account in the design of comprehensive regional and hemispherical climate reconstructions. The summer SAM reconstructions show no significant relationship to solar, greenhouse gas and volcanic forcing, with the exception of an extremely strong negative anomaly following the AD 1257 Samalas eruption. Furthermore, reconstructed pre-industrial summer SAM trends are very similar to trends obtained by model control simulations. We find that recent trends in the summer SAM lie outside the 5-95% range of pre-industrial natural variability.

title: NOAA/WDS Paleoclimatology - Johnson fire data from Upper Pine Flats, northern New Mexico - IMPD USUPF001

description: Tree-ring fire scars, tree ages, historical photographs, and historical surveys demonstrate that fire played different ecological roles for centuries across gradients of elevation, forest, and fire regime in the Taos Valley Watersheds. Fire regimes collapsed across these three adjoining watersheds by 1899, leaving all sites without fire for at least 119 years. Historical photographs and quaking aspen (Populus tremuloides Michx.) ages indicate that high-severity fire historically burned at multiple high-elevation subalpine sites in today’s Village of Taos Ski Valley, with large high-severity patches (> 640 ha). Low-severity, frequent (9 – 29 year median interval) surface fires burned in nearby mid-elevation dry conifer forests on south aspects in all watersheds. Fires were associated with drought during the fire year, preceded by wet years, with widespread fires commonly burning synchronously in multiple watersheds during more-severe drought years, including within all three watersheds in 1664, 1715, and 1842. In contrast, recent “large” wildfires have burned within single watersheds and therefore are likely not large in a historical context. Management to promote repeated low-severity fire and associated open forest stand structures is within the historical range of variability in the dry conifer forests of these watersheds, but in the high-elevation, subalpine forests different management approaches are required that balance ecological and socio-economic values while providing for public safety.

title: NOAA/WDS Paleoclimatology - Xiaobailong Cave, Southwest China 240 Year Speleothem Stable Isotope Data

description: Based on an absolutely dated stalagmite d18O record from Yunnan province, China, we reconstructed monsoon precipitation variations in southwest China since 1760 AD with a resolution of about 2 years. Combining the speleothem d18O and observed rainfall records, we find an overall decreasing trend in monsoon precipitation in this region and suggest that the recent drought in 2009-2012 AD has been the driest since 1760 AD. Our speleothem record is consistent with the monsoon precipitation records reconstructed from tree rings in the Nepal Himalaya and southeastern Tibetan Plateau. However, it is anti-correlated with a speleothem record from central India, which confirms the observed anti-phase variations of Indian monsoon precipitation with moistures from the Bay of Bengal and Arabian Sea on multi-decadal to centennial timescales during historical time. The long-term warming of tropical ocean may have caused the decrease of the land-sea thermal gradient and the amount of moisture transported from the Bay of Bengal, which may reduce precipitations in southwest China during the last 240 years. On decadal scale, El Nino-like conditions of tropical Pacific sea surface temperature may cause drought in this region. Climate model simulations suggest El Niño-like conditions exist in tropical Pacific under global warming scenarios. As a result, it is crucial to have adaptive strategies to overcome future declines in precipitation and/or drought events in southwest China.

title: NOAA/WDS Paleoclimatology - Mawmluh Cave, India 16-6 KYrBP Speleothem Stable Isotope Data

description: Northeastern (NE) India experiences extraordinarily pronounced seasonal climate, governed by the Indian summer monsoon (ISM). The vulnerability of this region to floods and droughts calls for detailed and highly resolved paleoclimate reconstructions to assess the recurrence rate and driving factors of ISM changes. We use stable oxygen and carbon isotope ratios (d18O and d13C) from stalagmite MAW-6 from Mawmluh Cave to infer climate and environmental conditions in NE India over the last deglaciation (16-6ka). We interpret stalagmite d18O as reflecting ISM strength, whereas d13C appears to be driven by local hydroclimate conditions. Pronounced shifts in ISM strength over the deglaciation are apparent from the d18O record, similarly to other records from monsoonal Asia. The ISM is weaker during the late glacial (LG) period and the Younger Dryas, and stronger during the Bolling-Allerød and Holocene. Local conditions inferred from the d13C record appear to have changed less substantially over time, possibly related to the masking effect of changing precipitation seasonality. Time series analysis of the d18O record reveals more chaotic conditions during the late glacial and higher predictability during the Holocene, likely related to the strengthening of the seasonal recurrence of the ISM with the onset of the Holocene.

title: NOAA/WDS Paleoclimatology - North Atlantic Globorotalia truncatulinoides Data During the Mid-Pleistocene

description: We use the coiling direction of planktic foraminifer Globorotalia truncatulinoides from four sites in the North Atlantic Ocean to assess spatial changes in upper-ocean hydrography during the mid-Pleistocene climate transition. Core top sediments indicate that the left-coiling (sinistral) variety dominates regions characterized by a deep permanent thermocline as is characteristic of the subtropical gyre (Ocean Drilling Program Sites 1058 and Deep Sea Drilling Project Site 607) while right-coiling (dextral) tests dominate the tropical (Ocean Drilling Program Site 925) and subpolar site (Deep Sea Drilling Project Site 552). We observe pronounced changes in the dominant coiling direction at the three subtropical to subpolar sites during the first of the more extreme glacial to interglacial transitions of the mid-Pleistocene climate transition, Marine Isotope Stages (MISs) 22 to 21. We interpret these observations to reflect an increase in poleward warm water advection. The time interval between MIS 21 and MIS 15 is marked by a pronounced absence of sinistral tests. Because G. truncatulinoides (sinistral) is a deep dwelling species, their absence may be related to a decrease in dissolved oxygen during warm interglacial intervals. At the tropical site, precessional-scale variations dominate changes in the coiling direction until midpoint interglacial MIS 23. Occurrences in the sinistral variety at this locale must be linked to cross-equatorial water transport in the North Brazil Current, and precessional-scale variations provide evidence for the sensitivity of the tropical regions to precessional forcing, at least until MIS 23 when this morphotype disappears in agreement with observation at other sites in the Atlantic Ocean.

title: NOAA/WDS Paleoclimatology - Cooper - Felbrigg Hall - QUSP - ITRDB BRIT066

description: We present an annually resolved reconstruction of spring-summer precipitation variability in East Anglia, UK (52-53N, 0-2E) for the period AD 900-2009. A continuous regional network of 723 living (AD 1590-2009) and historical (AD 781-1790) oak (Quercus sp.) ring-width series has been constructed and shown to display significant sensitivity to precipitation variability during the March-July season. The existence of a coherent common growth signal is demonstrated in oaks growing across East Anglia, containing evidence of near-decadal aperiodic variability in precipitation throughout the last millennium. Positive correlations are established between oak growth and precipitation variability across a large region of northwest Europe, although climate-growth relationships appear time transgressive with correlations significantly weakening during the early twentieth century. Examination of the relationship between oak growth, precipitation, and the North Atlantic Oscillation (NAO), reveals no evidence that the NAO plays any significant role in the control of precipitation or tree growth in this region. Using Regional Curve Standardisation to preserve evidence of low-frequency growth variability in the East Anglian oak chronology, we produce a millennial length reconstruction that is capable of explaining 32-35% of annual-to-decadal regional-scale precipitation variance during 1901-2009. The full length reconstruction indicates statistically significant anomalous dry conditions during AD 900-1100 and circa-1800. An apparent prolonged wetter phase is estimated for the twelfth and thirteen centuries, whilst precipitation fluctuates between wetter and drier phases at near centennial timescales throughout the fourteenth to seventeenth centuries. Above average precipitation reconstructed for the twenty-first century is comparable with that reproduced for the 1600s. The main estimated wet and dry phases reconstructed here appear largely coherent with an independent tree-ring reconstruction for southern-central England.
