Figure 3. Correlation of glacial and interglacial intensities of marine UK³³ temperature records with the inverted LR04 stack.

All correlations are calculated during the core period (2,150–2,900 kyr ago), except ODP-982, which is evaluated for 2,500–3,500 kyr ago as the data resolution between 2150 and 2500 kyr ago does not allow determination of the minima and maxima. Black circles indicate significance at P=0.05; green circles indicate records with interglacial peaks near the limit of UK³³ thermometry (>27 °C). (See Supplementary Fig.4 and Supplementary Table 1 for details and references of records.)
