Extended Data Fig. 1: Changes in Pacific upper-ocean temperature variability between the 21 ka and PI timeslice simulations.
From: Future increase in extreme El Niño supported by past glacial changes
Simulated 1 σ change (%) between the 21 ka and PI simulation temperature variability in the upper 200 m at grid-points corresponding to sites of available individual foraminiferal analyses (IFA) reconstructions (thick colored lines; Extended Data Table 3). Also shown are average calcification depths (with 95% confidence intervals) of four different species utilized in the IFA studies, based on Lakhani et al.25. Arrows next to core names indicate the sign of species-specific IFA (species indicated by abbreviation) dataset with a downward(/upward) arrow indicating reduced(/increase) variability (1 σ) during the LGM.
