Glacial-interglacial changes in the distribution of C3/C4 vegetation on the Chinese Loess Plateau have been related to East Asian summer monsoon intensity and position, and could provide insights into future changes caused by global warming. Here, we present δ(13)C records of bulk organic matter since the Last Glacial Maximum (LGM) from 21 loess sections across the Loess Plateau. The δ(13)C val...

Magnetic property has been proved to be a sensitive proxy to climate change for both terrestrial and marine sediments. Based on the schedule frame established by AMS 14C dating of foraminifera, detail magnetic analyses were performed for core PC24 sediments at sampling intervals of 2 cm to discuss magnetic sensitivity of marine sediment to climate during Holocene for the northern South China Se...

To study the geological environmental records of alpine-karst-type tufa deposits in eastern margin Tibetan Plateau, calcareous profile exposed by “8.8” Jiuzhaigou earthquake was taken as research object and combined with a field investigation. Further, petrography, sedimentology, chronology, elemental geochemistry were studied analyzed. The results show following. (1) Sparkling Lake deposited u...

This paper present a high resolution record of paleostorm events in the French Mediterrannean coast over the past 7000 years based on a long sediment core from lagoonal environment in Gulf of Lions. Using a multi-proxies approach on core associating grain size, faunal analysis, with a chronology derived from radiocarbon dates, we reconstruct Mid to Late Holocene history of backbarrier deposits ...

Assemblages of ostracodes from sediment cores illuminate lake-level history at decadal to centennial timescales during the late Holocene at Lake Tanganyika, East Africa. The ostracode-based lake-level curves for several cores resemble both each other and the only previously published lake-level record of comparable resolution for Lake Tanganyika during this interval, successfully reconstructing...

Identifying the position of Current Warm Period (CWP) in context long-term climatic trend is vital for understanding impact human activity on climate change. Reconstructions summer temperature and precipitation eight subregions China over past 22,000 years show that CWP these are all lower than Early to Middle Holocene. The timing Holocene peaks northern (including Northwest China, North Northe...

Understanding the timings of interhemispheric climate changes during the Holocene, along with their causes, remains a major problem of climate science. Here, we present a high-resolution 10Be chronology of glacier fluctuations in New Zealand's Southern Alps over the past 7000 years, including at least five events during the last millennium. The extents of glacier advances decreased from the mid...

[1] Existing paleoclimate data suggest a complex evolution of hydroclimate within the Indo-Pacific Warm Pool (IPWP) during the Holocene epoch. Here we introduce a new leaf wax isotope record from Sulawesi, Indonesia and compare proxy water isotope data with ocean-atmosphere general circulation model (OAGCM) simulations to identify mechanisms influencing Holocene IPWP hydroclimate. Modeling simu...

Abstract We measured stable isotopes (δ 18 O and δ 13 C) in Sphagnum cellulose that was extracted from a long peat core drilled the ombrotrophic Mohos bog, Ciomadul Mountain, Romania. The 10-m-long profile spans period 11,800 cal yr BP to present. C data indicate there were several cooling events warm periods area of bog during Holocene. 8.2-ka cold event, however, not detected using values. Re...
