Late-glacial and Holocene European pollen data
The European Pollen Database (EPD) is a community effort to archive and make available pollen sequences from across the European continent. Pollen sequences provide records that may be used to infer past vegetation and vegetation change. We present here maps based on 828 sites from the EPD giving an overview of changes in postglacial pollen assemblages in Europe over the past 15,000 years. The ...

متن کاملInterhemispheric correlation of late pleistocene glacial events.
A radiocarbon chronology shows that piedmont glacier lobes in the Chilean Andes achieved maxima during the last glaciation at 13,900 to 14,890, 21,000, 23,060, 26,940, 29,600, and >/=33,500 carbon-14 years before present ((14)C yr B.P.) in a cold and wet Subantarctic Parkland environment. The last glaciation ended with massive collapse of ice lobes close to 14,000(14)C yr B.P., accompanied by a...
متن کاملMechanisms of Abrupt Climate Change of the Last Glacial Period
[1] More than a decade ago, ice core records from Greenland revealed that the last glacial period was characterized by abrupt climate changes that recurred on millennial time scales. Since their discovery, there has been a large effort to determine whether these climate events were a global phenomenon or were just confined to the North Atlantic region and also to reveal the mechanisms that were...
متن کاملLate Pleistocene glacial advances in the western Tibet interior
a r t i c l e i n f o a b s t r a c t Keywords: cosmogenic 10 Be 21 Ne Tibet climate glacier It has long been observed that the timing of glacial advances is asynchronous across the Himalaya– Karakoram–Tibet Plateau (HKTP) but the climatic implications, if any, remain unclear. Resolving this question requires additional glacial chronologies from unique spatial and climatic regimes as well as an...
