How 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...
متن کاملThe 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 کاملHow cold were the tropics and subtropics at the Last Glacial Maximum?
The spatial pattern and magnitude of tropical and subtropical sea surface temperatures (SSTs) at the Last Glacial Maximum (LGM) have been a major challenge for many years. The range of the LGM tropical and subtropical cooling remains a major source of uncertainties for our understanding of the LGM climate. The global SST reconstruction for the LGM is an important ocean surface boundary conditio...
متن کاملHow cold was Europe at the Last Glacial Maximum? A synthesis of the progress achieved since the first PMIP model-data comparison
The Last Glacial Maximum has been one of the first foci of the Paleoclimate Modelling Intercomparison Project (PMIP). During its first phase, the results of 17 atmosphere general circulation models were compared to paleoclimate reconstructions. One of the largest discrepancies in the simulations was the systematic underestimation, by at least 10C, of the winter cooling over Europe and the Medit...
