European temperature variability.
Spatial field reconstruction of June-August (JJA) temperature anomalies (°C with respect to the 1961–1990 climatology) from 1230–1249 CE16. Maps representing a 5° × 5° land-only grid are based on a multi-proxy approach and Bayesian hierarchical modeling, with summer temperatures ranging from warm (1 °C) to cold (−2 °C). All maps were reproduced and modified from19.
