Koch, Claudio Latorre, Sergio Contreras, Janet Rethemeyer, Holger Wissel, Andreas Lücke
Fog is an important component of the coastal climate of northern Chile and southern Peru. Moisture and nutrients from fog maintain highly endemic vegetation (lomas) as well as unique ecosystems that thrive at elevations of ca. 900–1200 m asl. Although this epiphytic CAM bromeliad is well adapted to the extreme climate, declining stocks observed over the past decades question the long-term survival

The Atacama Desert, despite its extreme hostile conditions, still harbours traces of life in its dusty surface. Until now, it remains open whether organic molecules found in topsoils have their origin from in-situ biotic processes in the hyper-arid core, or whether and to which degree they stem from outside the desert and its border regions. In order to trace atmospheric organic matter input, we analyzed

Impact of Chondrites on trace metal distribution in the sapropel S7 (ODP Site 966): Implications for paleoenvironmental and paleoceanographic reconstructions Glob. Planet. Change (IF 3.9) Pub Date : 2024-02-15 Ricardo D. Monedero-Contreras, Francisco J. Rodríguez-Tovar, Francisca Martínez-Ruiz
Organic-rich deposits are valuable paleo-archives, recording significant paleoceanographic changes linked to past climate variations and marine deoxygenation events. The deposition of organic-rich sediments stops when bottom-water reventilation/oxygenation occurs. This impedes organic matter preservation, enabling macro and micro burrowing-organisms to recover and bioturbate the seafloor. In this sense

Optically stimulated luminescence dating of Paleolithic sites reveals population shifts in North China during the last glacial period Glob. Planet. Change (IF 3.9) Pub Date : 2023-12-21 Junyi Ge, Xiao Sun, Yan Li, Chunxue Wang, Lishuang Sheng, Ke Hu, Jiequn Hua, Xiaoling Zhang, Faxiang Huan, Shixia Yang, John W. Olsen, Xing Gao, Chenglong Deng
The Greater Khingan and Yanshan mountain ranges in northern China not only constitute a significant physical obstacle to the northward movement of monsoon circulation, but also represent a natural barrier for human migration and cultural interactions between in-migrating Paleolithic populations and those indigenous to East Asia during the Late Pleistocene. We dated two Paleolithic sites, Yangzhuangxishan

Projections of Greenland climate change from CMIP5 and CMIP6 Glob. Planet. Change (IF 3.9) Pub Date : 2023-12-16 Qinglin Zhang, Baojuan Huai, Minghu Ding, Weijun Sun, Weigang Liu, Jinpei Yan, Shuhui Zhao, Yetang Wang, Yuzhe Wang, Lei Wang, Jiahang Che, Jiahui Dou, Limin Kang
As the Arctic continues to warm faster than the global average, the Greenland ice sheet faces a warmer future without restrictions on greenhouse gas emissions. In this study, 24 CMIP5 and 21 CMIP6 models were used to analyze projections of precipitation, 2 m or near-surface air temperature (T2m), and 500 hPa geopotential height (Z500) over Greenland under medium and high emission scenarios. The multi-model

Evidence for variable provenance of Mercury anomalies during the Smithian–Spathian (Olenekian) Glob. Planet. Change (IF 3.9) Pub Date : 2023-12-16 Oluwaseun Edward, Marc Leu, Hugo Bucher, Sandrine Le Houedec, Franziska Blattmann, Christian Vérard, Thierry Adatte, Aymon Baud, Jeroen E. Sonke, Torsten Vennemann
Mercury (Hg) enrichment recorded in Smithian to Spathian (Olenekian) marine sedimentary successions has been used to link putative renewed Siberian Traps Large Igneous Province (STLIP) magmatism to climatic and environmental perturbations during this interval. To assess the potential for massive volcanism as a trigger for marine environmental disturbances across the Smithian – Spathian boundary (SSB)

Changes in the Indian Ocean surface hydrography driven by the seaway closure and monsoonal circulation since the late Oligocene Glob. Planet. Change (IF 3.9) Pub Date : 2023-12-12 Raj S.I.S. Podder, Anil K. Gupta, Steven Clemens, Prasanta Sanyal, M.K. Panigrahi
Closure of the East Tethyan and Indonesian gateways and development of the Indian or South Asian monsoon (SAM) wind system had profound control on Indian Ocean circulation. However, the dynamics of the Indian Ocean surface hydrography since the late Oligocene hitherto remains poorly constrained. Planktic foraminiferal relative abundance and stable isotope data from ODP Site 758A, eastern equatorial

No significant provenance changes in the Hoh Xil Basin, central-northern Tibetan Plateau, from the Late Cretaceous to the Early Miocene Glob. Planet. Change (IF 3.9) Pub Date : 2023-12-16 Leyi Li, Hong Chang, Andrew V. Zuza, Chen Wu, Xiaoke Qiang
The construction and uplift of the Tibetan Plateau has played a critical role in Cenozoic global climatic cooling due to extensive chemical weathering and establishment of the Asian monsoons. However, the models, mechanisms, and timing of Tibet's uplift remain rigorously debated. Important outstanding questions include what were surface elevations of the Tibetan Plateau prior to the Paleogene India-Asia

Spatio-temporal characteristics and driving factors of flash drought in northern China from 1978 to 2020 Glob. Planet. Change (IF 3.9) Pub Date : 2023-12-16 Ziyue Xue, Ying Chen, Yixing Yin, Weilin Chen, Yang Jiao, Peng Deng, Shibao Dai
In recent years, studies have found that drought can occur rapidly under anomalous atmospheric circulation patterns and underlying surface conditions. This type of drought is defined as “flash drought”. It is more sensitive to global warming compared to traditional drought and may become a common drought phenomenon in the future and require intensive research. But the characteristics and development
