title: NOAA/WDS Paleoclimatology - Flinders Reef - Sr/Ca and Oxygen Isotope Data

description: Low resolution (5-year) Sr/Ca and d18O samples, extending back to  1708 A.D., were analysed from a Porites coral core collected from  Flinders Reef, an offshore reef on the Queensland Plateau in the  western Coral Sea (17.5ï¿½ S, 148.3ï¿½ E). Using the Sr/Ca ratio as  a proxy for sea surface temperature (SST), we deconvolved a  salinity record by subtracting the SST signal from the d18O record.  Decadal variability in the reconstructed salinity record is closely  paralleled by changes in SST, with cooler (warmer) temperatures  recorded during wetter (drier) periods.  This relationship differs  from the conventional view often described for tropical areas,  where warm temperatures are associated with wet periods and cool  temperatures with dry periods. The anti-correlation between  reconstructed SST and salinity observed at Flinders Reef, however,  matches the climatic effects expected from variations in the  Interdecadal Pacific Oscillation (IPO), a recurrent pattern of  SST variability over the Pacific Ocean which is known to modulate  Australia's climate, in particular the impact of ENSO events on  decadal time scales. On longer timescales, salinity seems to have  remained almost constant for the last two centuries after a  progressive freshening of surface waters that culminated around  1800 A.D. Conversely, SSTs show a warming trend towards the late  20th century.
description: 5-yr interval Flinders Reef Sr/Ca and d18O data. Reconstruction of SSTs and salinity for 1708 to 1988. A 4.2 m long core of Porites sp. coral was analyzed from Flinders Reef, an offshore reef on the Queensland Plateau in the Coral Sea, ~250 km from the north-east coast of Australia. The coral core was cut lengthwise into 7mm thick slices and X-rayed to reveal annual density bands, which were used to establish the coral chronology. Samples were milled in continuous 5-year intervals down the full length of the core along major coral growth axes for the period 1988 to 1708 AD. Flinders Reef: 17.5ºS, 148.3ºE, 5m. depth.

title: NOAA/WDS Paleoclimatology - High-precision ice core measurements of CO2, d13C–CO2, CH4, and N2O covering T-IV and the centennial-scale CO2 jump at the onset of MIS 9

description: Using new high-precision ice core measurements of CO2, d13C-CO2, CH4, and N2O, this study provides the first carbon isotope constraints on a sizeable, centennial-scale CO2 jump at the onset of Marine Isotope Stage 9 (MIS 9). The very end of the Heinrich stadial (HS) characterizing Termination IV (T-IV, ca. 343 to 333 ka ago) shows a 250-year-long jump in greenhouse gas concentrations, followed by a 1.3 ka gradual decline back to initial concentration. During this so-called overshoot, CO2 and CH4 reach their highest levels (about 303 ppm and 800 ppb, respectively) over the past 800 ka prior to industrialization. The jump in CO2 is not accompanied by a change in d13C-CO2, suggesting that multiple mechanisms contributed to the exceptionally elevated CO2 values. Following the jump, a slow 0.2‰ enrichment in d13C-CO2 occurs. We propose that during the jump the sudden resumption of deepwater formation in the North Atlantic (NA) triggered an amplified release of CO2 from the Southern Ocean (SO) by a northward shift of the Intertropical Convergence Zone (ITCZ) and the SO westerlies, potentially in combination with a rapid land carbon release. The latter is expected from temporally enhanced wildfire activity related to higher fuel load and regionally changing weather conditions in connection to the ITCZ shift. A combination of marine proxy records and box model simulation suggests that the d13C-CO2 decrease expected from these processes is compensated by a net temperature increase in global sea surface temperature (SST) at the time of the AMOC resumption.

title: NOAA/WDS Paleoclimatology - Kotumsar Cave Geochemical Data from 8600 to 5600 Cal Yr BP

description: The Indian Summer Monsoon (ISM), a significant part of the global monsoon system, is driven by several climate forcing parameters. With the growing pace of global climate change scenario, there is need to focus on generating more high-resolution records of past monsoon. The ISM reconstructions from Core Monsoon Zone (CMZ) of India, which represents all-India Summer Monsoon Rainfall, are useful for a better understanding of its past variability. Such reconstructions from the CMZ are rather sparse and require detailed study based on various climate proxies. Here, we focus on the reconstruction of ISM variability during the mid-Holocene, based on stalagmite oxygen isotope ratios from the Kotumsar cave, Central India. We show that with decreasing insolation, monsoon started declining at the beginning of the mid-Holocene from 8.5 to 6.5 ka BP, which is also observed in the previous ISM reconstructions with coarser resolutions. However, a gradual increase in the rainfall is observed from 6.5 to 5.6 ka BP, a feature which is also noted in the East Asian Monsoon reconstruction from the Dongge cave. Our record mainly emphasizes on the occurrence of several abrupt weak monsoon events throughout the mid-Holocene. The occurrence of 8.2 and 5.9 ka abrupt weak monsoon events suggest that ISM variability is tightly bound to North-Atlantic Oscillation (NAO). We also demonstrate that ISM during the mid-Holocene was partly sensitive to El-Nino Southern Oscillation (ENSO), and displayed an inverse relationship.

title: NOAA/WDS Paleoclimatology - King - Chiricahua Mountains - PIEN - ITRDB AZ629

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.
