title: NOAA/WDS Paleoclimatology - Kelly fire data from Epilobium Lake, Yukon Flats, Alaska - IMPD USEPL009

description: Wildfire activity in boreal forests is anticipated to increase dramatically, with far-reaching ecological and socioeconomic consequences. Paleorecords are indispensible for elucidating boreal fire regime dynamics under changing climate, because fire return intervals and successional cycles in these ecosystems occur over decadal to centennial timescales. We present charcoal records from 14 lakes in the Yukon Flats of interior Alaska, one of the most flammable ecoregions of the boreal forest biome, to infer causes and consequences of fire regime change over the past 10,000 y. Strong correspondence between charcoal-inferred and observational fire records shows the fidelity of sedimentary charcoal records as archives of past fire regimes. Fire frequency and area burned increased ~6,000–3,000 y ago, probably as a result of elevated landscape flammability associated with increased Picea mariana in the regional vegetation. During the Medieval Climate Anomaly (MCA; ~1,000–500 cal B.P.), the period most similar to recent decades, warm and dry climatic conditions resulted in peak biomass burning, but severe fires favored less-flammable deciduous vegetation, such that fire frequency remained relatively stationary. These results suggest that boreal forests can sustain high severity fire regimes for centuries under warm and dry conditions, with vegetation feedbacks modulating climate–fire linkages. The apparent limit to MCA burning has been surpassed by the regional fire regime of recent decades, which is characterized by exceptionally high fire frequency and biomass burning. This extreme combination suggests a transition to a unique regime of unprecedented fire activity. However, vegetation dynamics similar to feedbacks that occurred during the MCA may stabilize the fire regime, despite additional warming.

title: NOAA/WDS Paleoclimatology - Papua New Guinea 230 Year Fossil and Modern Coral Isotope and Sr/Ca Data

description: El Niño-Southern Oscillation (ENSO) powers global interannual climate variability through changes in trade wind strength, temperature and salinity anomalies, sea level, and atmospheric circulation patterns. ENSO variability is well characterized in modern times, but instrumental records cannot fully describe natural ENSO variability due to the imprint of anthropogenic climate forcing. ENSO activity may also be affected by solar variability, but the response of ENSO to such changes is difficult to predict. We constructed a continuous, monthly resolved, spliced fossil Porites coral d18O and Sr/Ca record from Misima Island, Papua New Guinea, in the Western Pacific Warm Pool, spanning 233 yr (1411-1644 CE [Common Era]). The Misima coral record indicates that the surface ocean in this region experienced a small change in hydrologic balance with no change in temperature, extended periods of quiescence in El Niño activity, and no change in average amplitudes of El Niño events relative to signals captured in regional modern records. The reduced El Niño variability occurs during a known change in solar forcing, the initiation of the Little Ice Age. However, there is no clear relationship between the timing of changes in solar forcing and ENSO activity, implying that ENSO variability changes arise from internal dynamics. The century-scale switch between active and inactive El Niño states has not previously been recorded, and provides a new baseline for climate models and reconstructions.
description: Coral Sr/Ca and oxygen isotopes from a suite of fossil and near-modern Porites colonies were collected from storm deposits at Misima Island, Milne Bay Province, Papua New Guinea, Nariam Village Reef. The data are analyzed to investigate mean climate changes and ENSO variability during the initiation of the Little Ice Age. The compiled fossil record is 233 years long, and the near-modern record is 28 years long. Analytical precision on stable isotopic determinations is 0.05 per mil for d18O, and 0.02 per mil for d13C (1sigma, n = 393). Analytical precision for Sr/Ca ratios is 0.015 mmol/mol (1sigma). Isotopic values are reported in delta notation relative to the Vienna PeeDee Belemnite (VPDB) isotopic standard. Notes: Fossil samples MiF and MiG, age range: 1411.625-1644.625 CE. Modern sample MiC, age range: 1916.958-1944.958 CE. Resampled = linear resampling to monthly resolution. Filtered = wavelet filter, 2-8 years.

title: NOAA/WDS Paleoclimatology - Malevich - Little Juniper Mountain Update - JUOC - ITRDB OR095

description: This work presents the first tree-ring reconstructions of hydroclimate for the Upper Klamath River basin, which stretches from northern California into southern Oregon. The extended record provides a centuries-long perspective on the region’s hydroclimatic variability and context for water-related political issues that have erupted in recent years. Reconstructions of water-year precipitation for Klamath Falls, Oregon (extending 1564-2004 and 1000-2010 CE) were developed to compare past drought severity with drought severity of the instrumental record (extending 1896-2011). The reconstructions suggest that variability exhibited during the instrumental period captures extremes of moderate-to-long-duration (6-, 10-, and 20-year) droughts, but not of short (single-year and 3-year) and very long (50-year) droughts, which were more severe during the 11th-13th centuries. The late-16th-century “mega drought” is present in the Klamath River basin, though with less strength than in the neighboring Sacramento River basin. Cool-season storm tracks appear to be a direct driver of hydroclimatic variability, leading to instances of see-saw like relationships with neighboring regions, such as in the mid-14th century. In contrast, the larger area of drought in the 12th century is suggestive of a long-term northward shift in cool-season storm tracks.

title: NOAA/WDS Paleoclimatology - Gulf of Aden 40,000 Year Leaf Wax Deuterium Data

description: The timing and abruptness of the initiation and termination of the Early Holocene African Humid Period are subjects of ongoing debate, with direct consequences for our understanding of abrupt climate change, paleoenvironments, and early human cultural development. Here, we provide proxy evidence from the Horn of Africa region that documents abrupt transitions into and out of the African Humid Period in northeast Africa. Similar and generally synchronous abrupt transitions at other East African sites suggest that rapid shifts in hydroclimate are a regionally coherent feature. Our analysis suggests that the termination of the African Humid Period in the Horn of Africa occurred within centuries, underscoring the nonlinearity of the region's hydroclimate.

title: NOAA/WDS Paleoclimatology - Great Salt Lake, Utah 576 Year Water Level Reconstruction

description: Utah's Great Salt Lake (GSL) is a closed-basin remnant of the larger Pleistocene-age Lake Bonneville. The modern instrumental record of the GSL-level (i.e. elevation) change is strongly modulated by Pacific Ocean coupled ocean/atmospheric oscillations at low frequency, and therefore reflects the decadal-scale wet/dry cycles that characterize the region. A within-basin network of seven tree-ring chronologies was developed to reconstruct the GSL water year (September-August) level, based upon the instrumental record of GSL level from 1876 to 2005. The result was a 576-year reconstruction of the GSL level that extends from 1429 to 2005; all calibration-verification tests commonly used in dendroclimatology were passed. The reconstruction explains 48% of the variance in the instrumental GSL level and exhibits significant periodicity at sub-decadal scales over the past six centuries. Meanwhile, predominance of multi-decadal periodicity in the early half of the record shifted to quasi-decadal dominance in the latter half, and this is consistent with that of proxy reconstructions of the Pacific Decadal Oscillation. The GSL-level reconstruction is a crucial component to improving our insight into the possible controls of coupled ocean-atmosphere interactions on precipitation delivery.

title: NOAA/WDS Paleoclimatology - Cook - Joti Chilas - PIGE - ITRDB PAKI028

description: Past global climate changes had strong regional expression. To elucidate their spatio-temporal pattern, we reconstructed past temperatures for seven continental-scale regions during the past one to two millennia. The most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the nineteenth century. At multi-decadal to centennial scales, temperature variability shows distinctly different regional patterns, with more similarity within each hemisphere than between them. There were no globally synchronous multi-decadal warm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age, but all reconstructions show generally cold conditions between ad 1580 and 1880, punctuated in some regions by warm decades during the eighteenth century. The transition to these colder conditions occurred earlier in the Arctic, Europe and Asia than in North America or the Southern Hemisphere regions. Recent warming reversed the long-term cooling; during the period ad 1971-2000, the area-weighted average reconstructed temperature was higher than any other time in nearly 1,400 years.

title: NOAA/WDS Paleoclimatology - Lake Towuti, Indonesia 60KYr Multiproxy Sediment Data

description: The Indo-Pacific warm pool houses the largest zone of deep atmospheric convection on Earth and plays a critical role in global climate variations. Despite the region's importance, changes in Indo-Pacific hydroclimate on orbital timescales remain poorly constrained. Here we present high-resolution geochemical records of surface runoff and vegetation from sediment cores from Lake Towuti, on the island of Sulawesi in central Indonesia, that continuously span the past 60,000 y. We show that wet conditions and rainforest ecosystems on Sulawesi present during marine isotope stage 3 (MIS3) and the Holocene were interrupted by severe drying between ~33,000 and 16,000 y B.P. when Northern Hemisphere ice sheets expanded and global temperatures cooled. Our record reveals little direct influence of precessional orbital forcing on regional climate, and the similarity between MIS3 and Holocene climates observed in Lake Towuti suggests that exposure of the Sunda Shelf has a weaker influence on regional hydroclimate and terrestrial ecosystems than suggested previously. We infer that hydrological variability in this part of Indonesia varies strongly in response to high-latitude climate forcing, likely through reorganizations of the monsoons and the position of the intertropical convergence zone. These findings suggest an important role for the tropical western Pacific in amplifying glacial-interglacial climate variability.
