title: NOAA/WDS Paleoclimatology - 10Be Chronology of Khoton Nuur Glacial Landforms since the Last Glaciation, Mongolian Altai, Central Asia

description: Determining what caused the global Last Glaciation and last glacial termination, despite opposing orbital summer insolation signatures between the polar hemispheres, remains a puzzle of paleoclimatology. This problem can be addressed by comparing chronologies of glaciation from different latitudes and different climatic regimes in both hemispheres. Here, we present a 10Be surface-exposure chronology of glacial landforms constructed during and since the local Last Glaciation in the continental environment of interior Asia, in the high Mongolian Altai (49°N, 88°E). Four belts of lateral moraines document maximal phases of the former Khoton glacier at 35,400 ± 980 yrs ago; 23,430 ± 850 yrs ago; 20,780 ± 610 yrs ago; and 19,520 ± 550 yrs ago. Our chronology indicates that deglaciation from these maximal positions began as early as 18,810 ± 510 yrs ago, was well underway by 17,680 ± 510 yrs ago, and was nearly complete by 16,040 ± 490 yrs ago. Overall, our chronology shows that glaciation in western Mongolia coincided with the global Last Glacial Maximum (LGM), and that extensive recession from glacial-to-interglacial limits took place rapidly early in the last glacial termination, during Heinrich stadial 1. The transition from glacial to interglacial conditions led the demise of large Northern Hemisphere ice sheets and increase in radiative forcing agents by several millennia. We suggest that this rapid switch in the mode of glaciation implies the involvement of an additional climatic factor that could have produced locally rapid warming and deglaciation ~18,800 – 16,000 yrs ago.

The graphs consist of 2 parts, both of which show the X axis (time line) at the bottom with the earliest year of information on the left and the latest on the right. The Fire Index Plot is the topmost plot, and shows two variables: sample depth (the number of recording trees in each year) as a blue line along the left Y axis, compared with the percent trees scarred shown as gray bars along the right Y axis. Below, the Fire Chronology Plot consists of horizontal lines representing injuries by year on individual sampled trees. Symbols are overlain that denote the years containing the dendrochronologically-dated fire scars or injuries. The sample ID of each tree is displayed to the right of each line. The Composite Axis below represents the composite information from all individual series. The symbols used to represent the fire scars or injuries, and the filters used to determine the composite information, are shown in the legend. These graphs were created using the Fire History Analysis and Exploration System (FHAES). See https://www.fhaes.org/ for more information.

title: NOAA/WDS Paleoclimatology - Global Hydro-sensitive Coral d18O Records for Improved High-Resolution Temperature and Salinity Reconstructions

description: Stable oxygen isotopic ratios in corals (d18Ocoral) are commonly utilized to reconstruct climate variability beyond the limit of instrumental observations. These measurements provide constraints on past seawater temperature, due to the thermodynamics of isotopic fractionation, but also past salinity, as both salinity and seawater d18O (d18Osw) are similarly affected by precipitation/evaporation, advection, and other processes. We use historical observations, isotope-enabled model simulations, and the PAGES Iso2k database to assess the potential of d18Ocoral to provide information on past salinity. Using ‘pseudocorals’ to represent d18Ocoral as a function of observed or simulated temperature and salinity/d18Osw, we find that d18Osw contributes up to 89% of d18Ocoral variability in the Western Pacific Warm Pool. Although uncertainty in the d18Osw-salinity relationship influences the inferred salinity variability, corals from these sites could provide valuable d18Osw reconstructions. Coordinated in situ monitoring of salinity and d18Osw is vital for improving estimates of hydroclimatic change.

title: NOAA/WDS Paleoclimatology - Paleo-pCO2 Database:  Early Paleocene pCO2 Reconstruction Data from the San Juan Basin, New Mexico

description: Throughout the Phanerozoic, estimated CO2 levels from CO2 proxies generally correlate well with independent estimates of temperature. However, some proxy estimates of atmospheric CO2 during the Late Cretaceous and early Paleocene are low (<400 ppm), seemingly at odds with elevated sea surface temperature. Here we evaluate early Paleocene CO2 by applying a leaf gas-exchange model to Platanites leaves of four early Paleocene localities from the San Juan Basin, New Mexico (65.66-64.59 Ma). We first calibrate the model on two modern Platanus species, Platanus occidentalis and P. × acerifolia, where we find the leaf gas-exchange model accurately predicts present-day CO2, with a mean error rate between 5-14%. Applying the model to the early Paleocene, we find CO2 varies between ∼660 to 1140 ppm. These estimates are consistent with more recent CO2 estimates from boron, leaf gas-exchange, liverwort, and paleosol proxies that all suggest moderate to elevated levels of CO2 during the Late Cretaceous and early Paleocene. These levels of atmospheric CO2 are more in keeping with the elevated temperature during this period.

title: NOAA/WDS Paleoclimatology - Cleaveland - Orquideria - PSME - ITRDB MEX120

description: Interannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major vegetation productivity component: woody biomass growth. Here we compile a pantropical tree-ring network to show that annual woody biomass growth increases primarily with dry-season precipitation and decreases with dry-season maximum temperature. The strength of these dry-season climate responses varies among sites, as reflected in four robust and distinct climate response groups of tropical tree growth derived from clustering. Using cluster and regression analyses, we find that dry-season climate responses are amplified in regions that are drier, hotter and more climatically variable. These amplification patterns suggest that projected global warming will probably aggravate drought-induced declines in annual tropical vegetation productivity. Our study reveals a previously underappreciated role of dry-season climate variability in driving the dynamics of tropical vegetation productivity and consequently in influencing the land carbon sink.

title: NOAA/WDS Paleoclimatology - O'Connor fire data from Pinalenos_F12, Southeast Arizona - IMPD USF12001

description: In recent decades fire size and severity have been increasing in high elevation forests of the American Southwest. Ecological outcomes of these increases are difficult to gauge without an historical context for the role of fire in these systems prior to interruption by Euro-American land uses. Across the gradient of forest types in the Pinaleño Mountains, a Sky Island system in southeast Arizona that experienced two relatively large high-severity fires in the last two decades, we compared fire characteristics and climate associations before and after the onset of fire exclusion to determine the degree of similarity between past and recent fires. We use a gridded fire scar and demography sampling network to reconstruct spatially explicit estimates of fire extent and burn severity, as well as climate associations of fires from individual site to landscape scales from 1640 to 2008 C.E. We found that patterns of fire frequency, size, and severity were relatively stable for at least several centuries prior to 1880. A combination of livestock grazing and active fire suppression after circa 1880 led to (1) a significant reduction in fire spread but not fire ignition, (2) a conversion of more than 80% of the landscape from a frequent, low to mixed-severity fire regime to an infrequent mixed to high-severity fire regime, and (3) an increase in fuel continuity within a mid-elevation zone of dry mixed-conifer forest, resulting in increased opportunities for surface and crown fire spread into higher elevation mesic forests. The two most recent fires affecting mesic forests were associated with drought and temperature conditions that were not exceptional in the historical record but that resulted in a relative proportion of high burn severity up to four times that of previous large fires. The ecological effects of these recent fires appear to be more severe than any fire in the reconstructed period, casting uncertainty upon the recovery of historical species composition in high-severity burn patches. Significant changes to the spatial pattern, frequency, and climate associations of spreading fires after 1880 suggest that limits to fuel loading and fuel connectivity sustained by frequent fire have been removed. Coinciding factors of high fuel continuity and fuel loading, projected lengthening of the fire season, and increased variability in seasonal precipitation suggest that large high-severity fires, especially in mixed-conifer forests, will become the predominant fire type without aggressive actions to reduce fuel continuity and restore fire-resilient forest structure and species composition.
