The manuscript's abstract is: We present a reconstruction of tropical South American temperature anomalies over the last ~1600 years. The reconstruction is based on a highly resolved and carefully dated ammonium record from an ice core that was drilled in 1999 on Nevado Illimani in the eastern Bolivian Andes. It reveals that Medieval Warm Period and Little Ice Age type episodes are distinguishable in tropical South America, a region for which until now only very limited temperature proxy data exist. For the time period from about AD 1050 to 1300, our reconstruction shows relatively warm conditions that are followed by cooler conditions from the 15th to the 17th century, when temperatures dropped by up to 0.5 degree C below the 1961-1990 average. The last decades of the past millennium are characterized by warm temperatures that seem to be unprecedented in the last ~1600 years.
