title: NOAA/WDS Paleoclimatology - Mann and Jones 2003 Global Surface Temperatures over the Past Two Millennia

description: We present reconstructions of Northern and Southern Hemisphere mean surface temperature over the past two millennia based on high-resolution ‘proxy’ temperature data which retain millennial-scale variability. These reconstructions indicate that late 20th century warmth is unprecedented for at least roughly the past two millennia for the Northern Hemisphere. Conclusions for the Southern Hemisphere and global mean temperature are limited by the sparseness of available proxy data in the Southern Hemisphere at present.
description: Two hemispheric multi-proxy temperature reconstructions (based on local-correlation weighting, and areal weighting as described in Mann and Jones 2003). The global mean shown in the paper is the average of the two hemispheric reconstructions, while the interhemispheric difference is just NH-SH. The estimated uncertainties are constant and the one standard error uncertainties are: NH: +/- 0.16; SH: +/- 0.19; GLB: +/- 0.18; DIFF: +/- 0.25 All series are anomalies based on 1961-1990 instrumental reference period. Data are presented as both decadally-resolved series (added to this file 12/2004) and 40 year smoothed versions of the decadally-resolved reconstructions (as shown in Figure 2 of Mann and Jones).

title: NOAA/WDS Paleoclimatology - Urvina Bay - Radiocarbon Data

description: Radiocarbon (14C) content of surface waters inferred from a coral record from the Galápagos Islands increased abruptly during the upwelling season (July through September) after the El Niño event of 1976. Sea-surface temperatures (SSTs) associated with the upwelling season also shifted after 1976. The synchroneity of the shift in both 14C and SST implies that the vertical thermal structure of the eastern tropical Pacific changed in 1976. This change may be responsible for the increase in frequency and intensity of El Niño events since 1976.
description: Urvina Bay coral radiocarbon (14C) timeseries. Coral radiocarbon (Delta-14C) on untreated, low-speed drilled samples. Precision is ±4 per mil as documented by an in-house homogenized coral standard, and presented as AGE CORRECTED DELTA-14C [see Stuiver & Polach, 1977]. The sample cores were made on a Porites lobata coral, in Urvina Bay, Isabella Island, Galapagos Archipelago by G. Wellington, and supplied by R. Dunbar. Cores were split and cleaned with distilled water. After identifying the major vertical growth axis, the coral was sequentially sampled at 2 mm increments with a low-speed drill. Splits (~1 mg) were reacted in vacuo in a modified autocarbonate device at 90¡C and the purified  CO2 analyzed on a gas source stable isotope ratio mass spectrometer. The remaining sample splits (~7-8 mg) were placed in individual reaction chambers, evacuated, heated, and then acidified with orthophosphoric acid at 90C. The evolved CO2 was  purified, trapped, and converted to graphite in the presence of cobalt catalyst in individual reactors [Vogel et al., 1987].Graphite targets were measured at the Center for Accelerator Mass Spectrometry, Lawrence Livermore National Laboratory [Davis et al., 1990].  Radiocarbon results are reported as Delta-14C (per mil) as defined by Stuiver and Polach [1977] and include the d13C correction obtained from the stable isotope results. Analytical precision and accuracy of the radiocarbon measurements is ±4 per mil (1s) based on repeated analyses of an in-house homogenized near-modern coral and accepted secondary and tertiary radiocarbon standards. The coral died during the 1982/83 El Nino event. WATER DEPTH:  Top of coral water depth 1m. CORE LENGTH: 40cm. DATE OF COLLECTION: 11/15/90 (J. Wellington et al.). DESCRIPTION: ca. 1.2 km north of landing site 200m from shoreline

title: NOAA/WDS Paleoclimatology - La Parguera - del18O, del13C, and Reconstructed SST Data

description: We determined the seasonal environmental conditions during the Little Ice Age (LIA) by interpreting isotope proxies in the coral skeleton of Montastrea faveolata from the northeast Caribbean. The oxygen isotope composition was determined for three time intervals during the LIA (1700–1705, 1780–1785, 1810–1815), thought to correspond to the coldest intervals. The period 1984–1989 was used to represent modern calibration conditions. We determined that SSTs from the LIA intervals are nearly 2–3°C cooler than present. LIA cooling in the Caribbean may have resulted from regional oceanic and atmospheric circulation differences, especially in winter. We propose that a trough of cold air from the north Atlantic may have extended farther south than present, into the northern Caribbean. Although there are indications from Pacific corals that seasonality was greater during the LIA, this does not seem to be the case for the Caribbean.
description: Puerto Rico Coral Oxygen Isotope Data and LIA SST Reconstruction. Corals and modern SST data collected at the University of Puerto Rico marine station, La Parguera, 17 55'N, 64 00'W, Water Depth 7m. M. faveolata colonies used in this study are situated on the southwestern shore of Puerto Rico. Two coral heads both located at 7m water depth adjacent to each other were used in this study. One was used to obtain modern isotope data (1984-1989) and the other was used to obtain isotope data from the Little Ice Age. The cores were hydraulically drilled on June 2, 1994 and subsequently slabbed and x-rayed to reveal high density (HD) and low density (LD) banding. The distance between HD bands was approximately 10 mm per year. Each LD-HD band couplet represents one year of growth and chronology was determined by counting number of couplets starting with the top layer, which represented the year 1994. Samples for isotopic analysis were extracted from the slabs by the method of Watanabe and Oba, 2000. Isotope values are reported vs PDB, and water temperature values are in degrees C.

title: NOAA/WDS Paleoclimatology - King - Lady of the Woods - ABMA - ITRDB OR137

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.

title: NOAA/WDS Paleoclimatology - North fire data from Rock Creek Riparian/upland - IMPD USRO2001

description: Fire is an important ecological process in many western U.S. coniferous forests, yet high fuel loads, rural home construction and other factors have encouraged the suppression of most wildfires. Using mechanical thinning and prescribed burning, land managers often try to reduce fuels in strategic areas with the highest fuel loads. Riparian forests, however, are often designated as areas where only limited management action can take place within a fixed-width zone. These highly productive forests have developed heavy fuel loads capable of supporting stand-replacing crown fires that can alter wildlife habitat and ecosystem function, and contribute to stream channel erosion. Objectives of this study were to determine whether adjacent coniferous riparian and upland forests burned historically with different frequencies and seasonalities, and whether these relationships varied by forest, site, and stream characteristics. We measured dendrochronological fire records in adjacent riparian and upland areas across a variety of forest, site and stream conditions at 36 sites in three sampling areas in the northern Sierra Nevada.  Riparian fire return intervals (FRI) ranged from 8.4 to 42.3 years under a liberal filter (mean 16.6), and 10.0 to 86.5 years under a conservative filter (mean 30.0). Upland FRI ranged from 6.1 to 58.0 years under a liberal filter (mean 16.9), and 10.0 to 56.3 years under a conservative filter (mean 27.8). Riparian and upland fire return intervals were significantly different in only one quarter of the sites we sampled. Riparian and upland areas did not burn with different seasonalities, and fire events occurred primarily during the late summer-early fall dormant season in both riparian and upland areas (88% and 79% of scars, respectively). FRI was shorter in forests with a higher proportion (>22.7-37.6%) of fire-tolerant pine(Pinus spp.), sites east of the Sierra crest, lower elevation sites (<1944 m), and riparian zones bordering narrower, more incised streams (width/depth ratio <6.2). Upland areas exhibited a greater degree of fire-climate synchrony than riparian areas. Our study suggests that Sierra Nevada coniferous riparian forests bordering many montane streams might be managed for fuel loads and fire return intervals similar to adjacent upland forests.
