title: NOAA/WDS Paleoclimatology - Valmiki Cave  Geochemical Data from 15600 to 13200 Cal Yr BP

description: We present a high resolution record of Indian summer monsoon (ISM) variability during the last deglacial period. The record is based on high precision measurements of oxygen isotopes (δ18O) in 263 sub-samples from a ~ 18 cm long stalagmite (VSPM1) sample collected from the Valmiki cave in the southern India. The chronological framework is based on high precision U-Th dating in 8 sub-samples at regular intervals. The stalagmite exhibits a variable growth rate ranging from ~ 0.03 to 0.80 mm/yr with 9 years as an average sampling resolution for δ18O. X-ray diffraction analysis shows that the sample is composed of aragonite mineral. The δ18O record provides a strong evidence of abrupt changes in ISM activity between approximately 15,610 and 13,160 yr BP (before 1950 AD). Highly negative δ18O values at ~ 15,610 and 15,250 yr BP are suggestive of a wet climate followed by less negative δ18O at ~ 15,240 to 14,750 yr BP indicating relatively dry climate. These dry and arid conditions are punctuated by two wet events at 15,030 and 14,910 yr BP. A marked increase in δ18O between approximately 14,660 and 14,370 yr BP suggests weakening in ISM activity, followed by a gradual decrease in δ18O between 14,370 and 13,560 yr BP indicating strengthening of ISM. However we cannot rule out the possibility of some past flooding event influencing δ18O of VSPM1. Wavelet analysis of δ18O time series suggests strong influence of solar forcing on ISM activity. The amplitude variance of δ18O reveal decadal to centennial scale variability in monsoonal activity during the last deglaciation.

title: NOAA/WDS Paleoclimatology - Folland et al. 2009 Summer North Atlantic Oscillation Reconstruction

description: Summer climate in the North Atlantic–European sector possesses a principal pattern of year-to-year variability that is the parallel to the well-known North Atlantic Oscillation in winter. This summer North Atlantic Oscillation (SNAO) is defined here as the first empirical orthogonal function (EOF) of observed summertime extratropical North Atlantic pressure at mean sea level. It is shown to be characterized by a more northerly location and smaller spatial scale than its winter counterpart. The SNAO is also detected by cluster analysis and has a near-equivalent barotropic structure on daily and monthly time scales. Although of lesser amplitude than its wintertime counterpart, the SNAO exerts a strong influence on northern European rainfall, temperature, and cloudiness through changes in the position of the North Atlantic storm track. It is, therefore, of key importance in generating summer climate extremes, including flooding, drought, and heat stress in northwestern Europe. The El Niño–Southern Oscillation (ENSO) phenomenon is known to influence summertime European climate; however, interannual variations of the SNAO are only weakly influenced by ENSO. On interdecadal time scales, both modeling and observational results indicate that SNAO variations are partly related to the Atlantic multidecadal oscillation. It is shown that SNAO variations extend far back in time, as evidenced by reconstructions of SNAO variations back to 1706 using tree-ring records. Very long instrumental records, such as central England temperature, are used to validate the reconstruction. Finally, two climate models are shown to simulate the present-day SNAO and predict a trend toward a more positive index phase in the future under increasing greenhouse gas concentrations. This implies the long-term likelihood of increased summer drought for northwestern Europe.

title: NOAA/WDS Paleoclimatology - Cariboo Lake, British Columbia, Canada Laminated Glaciolacustrine Sediment Data from 2017-2 BP

description: Records of sedimentation collected from Cariboo Lake, situated in the northern Columbia Mountains, British Columbia, Canada, are analyzed to assess Holocene fluvial and glacial watershed dynamics. The aim of this study is to provide a proxy record of Holocene hydroclimate and glacier change from sediment archives at a higher temporal resolution compared to available records for the Interior Ranges of British Columbia. Deglacial and Holocene sediment accumulation is observed to reach a maximum thickness of 35 m in deep parts of the lake, using sub-bottom acoustic soundings. A transition from massive to well-stratified sediments is observed in the sub-bottom acoustic record during final phases of valley deglaciation in the region (~10.5–9 cal ka BP). Laminae couplets are interpreted to be deposited annually according to two 14C dates and a varve counting chronology. Two long cores, 2.9 and 3.8 m in length, were selected for analysis with estimated basal dates of 2 cal ka BP. Trends in downcore sediment characteristics were linked to environmental changes in the glaciated catchment headwaters at a temporal resolution of ~100 yrs. Upstream lake filtering of river floodplains and lakes prevented finding a higher temporal resolution linkage between the sediment characteristics and headwater fluvial and glacial activity. Despite some upstream filtering, the Cariboo River was found to be the primary source of sediment to the long core sites. Observed grain size and varve thickness from two long cores show above average trends which are coincident with cooler temperatures and the primary glacier advances over the last 2 ka.

title: NOAA/WDS Paleoclimatology - King - Joffrey Lake - PIEN - ITRDB CAN722

description: Extreme summer temperatures are increasingly common across the Northern Hemisphere and inflict severe socioeconomic and biological consequences. In summer 2021, the Pacific Northwest region of North America (PNW) experienced a 2-week-long extreme heatwave, which contributed to record-breaking summer temperatures. Here, we use tree-ring records to show that summer temperatures in 2021, as well as the rate of summertime warming during the last several decades, are unprecedented within the context of the last millennium for the PNW. In the absence of committed efforts to curtail anthropogenic emissions below intermediate levels (SSP2–4.5), climate model projections indicate a rapidly increasing risk of the PNW regularly experiencing 2021-like extreme summer temperatures, with a 50% chance of yearly occurrence by 2050. The 2021 summer temperatures experienced across the PNW provide a benchmark and impetus for communities in historically temperate climates to account for extreme heat-related impacts in climate change adaptation strategies.

description: Our study examines the application of using blue intensity (BI) methods to develop a late summer maximum temperature (Tmax) reconstruction for the Southern Rocky Mountains - a mid-latitude (i.e., 36N), arid region in North America. We reconstruct August-September (AS) Tmax for the period 1735-2015 CE using a composite latewood BI (LWB) Engelmann spruce (Picea engelmannii Parry ex Engelm.) chronology from multiple sites across the Sangre de Cristo Mountains in Northern New Mexico, USA. This study presents the first BI-derived temperature reconstruction for the lower mid-latitudes (30-45N) of North America. We compare the climate response of multiple tree-ring parameters: LWB, earlywood BI (EWB), DeltaBI (earlywood BI minus latewood BI), ring width (RW), and maximum latewood density (MXD). Of all parameters, the site-composite LWB and DeltaBI chronologies show the strongest correlations with AS Tmax. Reconstructed AS Tmax demonstrates fluctuating warm and cool periods during the latter portion of the Little Ice Age (ca. 1730-1850) and pronounced warming through the early to mid-twentieth century (ca. 1920-1950s). The reconstruction also documents substantial warming over the last decade, the trend of which appears to be anomalous within the context of the past ca. 280 years. We highlight the potential for BI methods to be successfully used at high-elevation, mid-latitude locations where temperature proxy datasets are scarce or non-existent. As many places across the mid-latitudes lack contiguous, temporally resolved, decadal-scale paleotemperature proxies, we suggest here that BI methods can be effective at improving the spatial gaps in the Northern Hemisphere temperature proxy network.

title: NOAA/WDS Paleoclimatology - King - Klamath Regional - TSME - ITRDB OR132

description: Across western North America (WNA), 20th-21st century anthropogenic warming has increased the prevalence and severity of concurrent drought and heat events, also termed hot droughts. However, the lack of independent spatial reconstructions of both soil moisture and temperature limits the potential to identify these events in the past and to place them in a long-term context. We develop the Western North American Temperature Atlas (WNATA), a data-independent 0.5° gridded reconstruction of summer maximum temperatures back to the 16th century. Our evaluation of the WNATA with existing hydroclimate reconstructions reveals an increasing association between maximum temperature and drought severity in recent decades, relative to the past five centuries. The synthesis of these paleo-reconstructions indicates that the amplification of the modern WNA megadrought by increased temperatures and the frequency and spatial extent of compound hot and dry conditions in the 21st century are likely unprecedented since at least the 16th century.

title: NOAA/WDS Paleoclimatology - Malo Channel, Espiritu Santo Island - Stable Isotope and Elemental Data

description: Coral skeletal geochemistry offers the potential to reconstruct the  sea surface salinity (SSS) history of the tropical oceans on seasonal  to interannual and perhaps centennial timescales because of the strong  link between variation in SSS and seawater d18O in tropical regions.  We explore this potential using a monthly resolved, 65-year record of  skeletal d18O and Sr/Ca variations in a Porites coral from Espiritu Santo,  Vanuatu. We demonstrate that El Nino-Southern Oscillation-related climate  variability strongly influences coral d18O at Santo through local salinity  changes associated with the position of the South Pacific Convergence Zone  and the movement of its associated salinity front. Such a demonstration  provides the "ground truth" data that can be used to place paleoclimate  variability estimated using existing fossil coral records from this region  into a modern conceptual framework. We also evaluate different methods of  combining coral d18O and Sr/Ca to reconstruct SSS and conclude that the  coral d18O anomaly time series provides the best fit to recent in situ  SSS data at Santo.
description: Analyses of stable isotopes (Delta 18O, Delta 13C) and elemental ratios (Sr/Ca, Mg/Ca in mmol/mol) of a modern Porites lutea coral obtained in June of 1992. The approximately 65 years of data were used to investigate salinity and temperature variations in that region as they relate to South Pacific Convergence Zone activity and ENSO. The age model has been adjusted over the 1992 calendar year to reflect a June 1992 sampling date as opposed to October 1992, which was mistakenly reported in the paper. The ages of samples preceding 1992.16 remain unaffected by this correction. Porites lutea sample from Malo Channel, Espritu Santo, Vanuatu (15.7S, 167.2E, 1.5m depth)
