The dataset provides a compilation of quantitative European summer temperature reconstructions for the late-glacial periods of the Bølling-Allerød interstadial (~14.3 to 13 ka BP) and Younger Dryas stadial (~12.8 to 11.7 ka BP). July temperature reconstructions are based on multi-proxy biological data from 122 European lake sediment records. Temperature proxies consist mainly of chironomids and plant macrofossils.

Comments

The multi-proxy summer temperature reconstruction is based on a compilation of previously published data from 122 sites. The July temperature quantification based on plant macrofossils (incl. some aquatic microfossils) are based on a common northern distribution limit of climate indicator plant species as described in Schenk et al. (2018). References to the original publications of each site are provided within the dataset.
