Description
Changes in temperature and/or precipitation were inferred from plant macrofossils, pollen, fungal spores, testate amebae and peat humification in peat monoliths collected from the Valle de Andorra about 10 km to the northeast of Ushuaia, Tierra del Fuego, Argentina (54.75°S, 68.4°W). Mauquoy et al. report finding evidence for a period of warming-induced drier conditions from AD 960-1020 that "seems to correspond to the Medieval Warm period (MWP, as defined in the Northern Hemisphere)" and "shows that the MWP was possibly synchronous in both hemispheres."
