Multi-archive summer temperature reconstruction for the European Alps, AD 1053–1996
2012
We present a multi-archive, multi-proxy summer temperature reconstruction for the European Alps covering the period AD 1053e1996 using tree-ring and lake sediment data. The new reconstruction is based on nine different calibration approaches and errors were estimated conservatively. Summer temperatures of the last millennium are characterised by two warm (AD 1053e1171 and 1823e1996) and two cold phases (AD 1172e1379 and 1573e1822). Highest pre-industrial summer temperatures of the 12th century were 0.3 � C warmer than the 20th century mean but 0.35 � C colder than proxy derived
The future of paleoclimate
2021
Our understanding of natural climate variability rapidly declines over the Common Era (CE) as the pre-instrumental temperature amplitude differs substantially among large-scale reconstructions. Highlighting such differences and emphasizing paleoclimatic findings is crucial for placing anthropogenic climate change in a long-term context. We argue that more proxy records are needed to accurately reconstruct first millennium CE temperature variability and value regional studies producing such data.
