Extended Data Fig. 6: Reconstructed temperature extremes.
From: 2023 summer warmth unparalleled over the past 2,000 years
Comparison of temperature anomalies in the four warmest (246, 282, 1061, 986 CE) and four coldest summers (535, 627, 1601, 1642 CE) identified in ensemble mean reconstruction (see Table 1) with estimates from other NH extra-tropical reconstructions. “x” indicates if values are missing due to limited reconstruction lengths.
