On the differences between Last Glacial Maximum and Mid-Holocene climates in southern South America simulated by PMIP3 models
Differences between climate conditions during the Last Glacial Maximum (LGM) and the Mid-Holocene (MH) in southern South America inferred from the state-of-the-art PMIP3 paleoclimatic simulations are described for the first time in this paper. The aim is to expose characteristics of past climate cha...
