The Last Glacial Maximum.
We used 5704 14C, 10Be, and 3He ages that span the interval from 10,000 to 50,000 years ago (10 to 50 ka) to constrain the timing of the Last Glacial Maximum (LGM) in terms of global ice-sheet and mountain-glacier extent. Growth of the ice sheets to their maximum positions occurred between 33.0 and 26.5 ka in response to climate forcing from decreases in northern summer insolation, tropical Pac...
متن کاملA note on the extent of glaciation throughout the Himalaya during the global Last Glacial Maximum
Quantitative chronologies for the impressive glacial successions that occur throughout the Himalaya have, until recently, been almost totally lacking. Within the last decade two new techniques have promised to remedy this situation. These techniques, optically stimulated luminescence and cosmogenic nuclide surface exposure dating, enable the age of many glacial features to be determined and hav...
متن کاملClosing the sea level budget at the Last Glacial Maximum.
Establishing the volume of excess ice contained in the global ice sheets during the Last Glacial Maximum (LGM; ∼26,000–19,000 y ago) remains a longstanding problem in Ice Age climate dynamics. Expressed as the equivalent lowering of global mean sea level (GMSL), estimates of this value have varied from 105 (1) to 163 m (2), with many estimates suggesting ∼120 m (3). This wide range introduces s...
متن کاملHow cold was the Last Glacial Maximum?
[1] We present a new approach to estimate the magnitude of global-mean cooling (dTLGM) at the Last Glacial Maximum (LGM) relative to the pre-industrial climate, by combining an ensemble of coupled climate model simulations with empirical constraints on regional cooling inferred from proxy data. We have generated a large ensemble of paired runs ( 100) for pre-industrial and LGMboundary condition...
