An exceptional discovery of 256 individual pine trees within the town of Zürich in 2013 (referred to as the BINZ material), for which first radiocarbon dates now suggest a time window roughly between 14 000 and 11 000 BP, implies strong evidence to fill existing gaps in the Late Glacial tree-ring chronology around 12 500 BP.
Africa is very likely to warm more than global average during this century. Especially (semi-)arid regions are endangered to experience particularly high warming and possibly catastrophic droughts. The prediction of the climate change impact on these regions requires information about the past climate conditions in high temporal and spatial resolution. There is a massive lack of transregional highly time resolved climate proxy data for the African continent.
The overall projective of CAHOL is the reconstruction of the Holocene climate, with special focus on tipping points, from continental and marine archives to better understand the driving mechanisms of abrupt climate changes and the interaction between the monsoon and west wind climates. CAHOL is part of the BMBF research program CAME II: “Crossing climatic tipping points – consequences for Central Asia“.
Several joint expeditions by Russian, American, and German scientist mainly in 1998, 2000, and 2003 revealed that the sedimentary record of 12 km wide lake El'gygytgyn (Chukotka Peninsula, Northeast Siberia) filling a meteorite impact crater, has a high potential for a long-term paleoclimate study. Sediment cores were drilled 2008/2009 during an ICDP campaign.
PROGRESS stands for "Potsdam Research Cluster for Georisk Analysis, Environmental Change and Sustainability". It is a joint research project subsidised by the German Federal Ministry for Education and Research (BMBF) within the framework of „Advanced Research and Innovation in the New Federal States.
The joint research project CADY - Central Asian climate DYnamics aims to reconstruct the Holocene climate variability and regional hydrology in Central Asia along three transects on the Tibetan Plateau. CADY is part of the BMBF research program "Central Asia and Tibet: Monsoon dynamics and geo-ecosystems".
DecLakes, a project within the ESF Eurocores EuroCLIMATE program, will provide six well-dated high-resolution records of the oxygen-isotope composition of past precipitation derived from ostracods in the profundal lake sediments from the Northern, Western and Southern margin of the Alps and from North-eastern Poland.
Investigations of the East Asian monsoon system over the last glacial-interglacial cycle are based on sediments of small lakes with high sedimentation rates from South- and Northeast-China. Main aspects of palaeoclimatic reconstructions are variations of precipitation and dust flux, as well as vegetation dynamics.
The Near East region encompasses a unique set of contrasting environments, where changes in hydrological regimes are probably the most prominent expressions of climate variability. Environmental changes in this region had a profound impact on prehistoric and early historic cultural evolution of mankind.
Stratigraphy, from Latin stratum + Greek graphia, is the description of all rock bodies forming the Earth's crust and their organization into distinctive, useful, mappable units based on their inherent properties or attributes in order to establish their distribution and relationship in space and their succession in time, and to interpret geologic history.
