title: NOAA/WDS Paleoclimatology - Dunde Ice Core 1500 Year d18O, Dust, Anion, and Accumulation Data

description: Three lines of evidence for abrupt tropical climate change, both past and present, are presented. First, annually and decadally averaged δ18O and net mass-balance histories for the last 400 and 2,000 yr, respectively, demonstrate that the current warming at high elevations in the mid- to low latitudes is unprecedented for at least the last 2 millennia. Second, the continuing retreat of most mid- to low-latitude glaciers, many having persisted for thousands of years, signals a recent and abrupt change in the Earth’s climate system. Finally, rooted, soft-bodied wetland plants, now exposed along the margins as the Quelccaya ice cap (Peru) retreats, have been radiocarbon dated and, when coupled with other widespread proxy evidence, provide strong evidence for an abrupt mid-Holocene climate event that marked the transition from early Holocene (pre-5,000-yr-B.P.) conditions to cooler, late Holocene (post-5,000-yr-B.P.) conditions. This abrupt event, ≈5,200 yr ago, was widespread and spatially coherent through much of the tropics and was coincident with structural changes in several civilizations. These three lines of evidence argue that the present warming and associated glacier retreat are unprecedented in some areas for at least 5,200 yr. The ongoing global-scale, rapid retreat of mountain glaciers is not only contributing to global sea-level rise but also threatening freshwater supplies in many of the world’s most populous regions.

title: NOAA/WDS Paleoclimatology - Tropical Pacific benthic isotope record for 0-5 Ma

description: Benthic foraminifer and δ13C data from Site 849, on the west flank of the East Pacific Rise (0° 11 'N, 110°3 l'W; 3851 m), give relatively continuous records of deep Pacific Ocean stable isotope variations between 0 and 5 Ma. The mean sample spacing is 4 k.y. Most analyses are from Cibicides wuellerstorfi> but isotopic offsets relative to Uvigerina peregrina appear roughly constant. Because of its location west of the East Pacific Rise, Site 849 yields a suitable record of mean Pacific Ocean δ'3C, which approximates a global oceanic signal. The ~l00-k.y.-period climate cycle, which is prevalent in δ18θ does not dominate the long-term δ13C record. For δ13C, variations in the -400- and 41-k.y. periods are more important. Phase lags of δ13C relative to ice volume in the 41- and 23-k.y. bands are consistent with δ13C as a measure of organic biomass. A model-calculated exponential response time of 1-2 k.y. is appropriate for carbon stored in soils and shallow sediments responding to glacial-interglacial climate change. Oceanic δ13C leads ice volume slightly in the 100-k.y. band, and this suggests another process such as changes in continental weathering to modulate mean river δ13C at long periods. The δ13C record from Site 849 diverges from that of Site 677 in the Panama Basin mostly because of decay of 13C-depleted organic carbon in the relatively isolated Panama Basin. North Atlantic to Pacific δ13C differences calculated using published data from Sites 607 and 849 reveal variations in Pliocene deep water within the range of those of the late Quaternary. Maximum δ13C contrast between these sites, which presumably reflects maximum influx of high-δ13C northern source water into the deep North Atlantic Ocean, occurred between 1.3 and 2.1 Ma, well after the initiation of Northern Hemisphere glaciation. Export of high-δ13C North Atlantic Deep Water from the Atlantic to the circumpolar Antarctic, as recorded by published δ13C data from Subantarctic Site 704, appears unrelated to the North Atlantic-Pacific δ13C contrast. To account for this observation, we suggest that deep-water formation in the North Atlantic reflects northern source characteristics, whereas export of this water into the circumpolar Antarctic reflects Southern Hemisphere wind forcing. Neither process appears directly linked to ice-volume variations.

title: NOAA/WDS Paleoclimatology - Raymo 1992 DSDP Site 607 Isotope Data and Age Models

description: Deep sea δ18O records from benthic foraminifera provide a high-resolution overview of global ice volume changes over the last three million years, the interval typically referred to as the Northern Hemisphere Ice Ages. Prior to 2.7 Ma global climate appears to have been typically warmer than at present and the possibility of Antarctic deglaciation is suggested by depleted δ18O values observed prior to 2.9 Ma. Between 3.1 and 2.6 m.y., cold/warm oscillations are superimposed upon a gradual cooling trend which culminated with the growth of significant continental ice sheets in the northern hemisphere (equivalent to ~60m sea level change). Climate conditions during these cold extremes would be most analogous to late Pleistocene isotopic substages 5b and 5d. Since 2.7 Ma interglacial climate extremes have rarely been warmer than the Holocene. Significant 100 Kyr variance is observed during the late Pliocene interval and suggests that large ice sheets are not needed for climate to vary at the 100 Kyr eccentricity frequency. However, the rapid rates of climate change observed for late Pleistocene “terminations” are not typically observed earlier in the Plio-Pleistocene, although rates of ice decay are still usually faster than rates of ice growth. Fluctuations in North Atlantic Deep Water production (indicated by a δ13C gradient proxy) are not uniquely linked with climate transitions as indicated by δ18O and ice core CO2 records, implying that NADW production may be responding to factors other than global continental ice volume.

title: NOAA/WDS Paleoclimatology - Barron et al. 2005 High Resolution Guaymas Basin Diatom and Silicoflagellate Data

description: High-resolution records of calcium carbonate, biogenic opal, diatoms, and silicoflagellates from western Guaymas Basin gravity core GGC55 and piston core JPC56 and eastern Guaymas Basin DSDP Site 480 reveal a complex paleoceanographic history of the central Gulf of California during the past 15,000 years. Prior to ~6.2 ka, the eastern and western Guaymas Basin proxy records were remarkably similar. After conditions similar to those of today during the Bolling-Allerod, the Younger Dryas (YD) saw a major drop in diatom production, coincident with increased calcium carbonate and tropical microfossils suggestive of El Nino-like conditions. Biosiliceous productivity began increasing during the latter part of the YD, but it was only during the earliest Holocene (11.6 to 11.0 ka) that conditions similar to those of the Bolling-Allerod returned to the central Gulf. Between around 11.0 and 6.2 ka, tropical diatoms and silicoflagellates were virtually absent from the central Gulf, as relatively cooler and fresher surface waters resembling those of the modern northern Gulf were present in the central Gulf. Beginning at about 6.2 ka, tropical diatoms and silicoflagellates began increasing in the central Gulf, and coccoliths returned to western Gulf sediments. The onset of modern-day monsoon conditions in the American Southwest required the presence of warm SSTs in the northern Gulf, which probably did not occur until after about 5.4 ka, when tropical diatoms and silicoflagellates became relatively common in the central Gulf. Modern east-west contrasts, which arise from late winter-early spring coastal upwelling on the mainland side and lower diatom productivity on the western side of the Gulf, commenced between 6.2 and 5.4 ka, possibly due to a shift in the direction of late winter-early spring winds more towards the southeast, or down the axis of the Gulf. This proposed wind shift might have ultimately been due to a late Holocene strengthening of ENSO-like conditions in the eastern equatorial Pacific.

title: NOAA/WDS Paleoclimatology - Rutishauser et al. 2007 Swiss Spring Phenological Index

description: Plant phenological observations are accurately dated information of seasonal vegetation variability in midlatitude climates. In order to extend phenological records into the past and assess climate impacts on vegetation on long timescales, there is a need to make use of historical observations of plant phenology.  Here we present a continuous, annually resolved reconstruction of a statistical "Spring plant" defined as the weighted mean for the flowering of cherry and apple tree and budburst beech from plant phenological observations across a range of sites in Switzerland from 1702 to 2005. The reconstruction indicates a statistical reconstruction uncertainty (±3.4 days) at interannual timescale. The earliest and the latest year were observed in 1961 (14 April) and 1879 (13 May), respectively. In the context of the last 300 years, the recent three decades do not show a preponderance of very early years as expected from increased spring temperatures. Most of the years in the period after 1990, however, are earlier than the reconstruction mean (27 April). The 1940s, 1910s, 1890s and the early 18th century are periods with similarly early starts of spring season in comparison with the recent decades. Moving linear trend analysis shows unprecedented agreement towards earlier spring onsets in observed and temperature-based, reconstructed plant phenological records in the late 20th/early 21st century. Our reconstructed "Spring plant" provides long-term evidence of vegetation variability for comparisons with temperature measurement and other spring onset indicators such as snow melt. The multicentennial long record offers a high potential for applications in long-term climate impact studies and vegetation model validations.
