Extended Data Table 1 Paired hydroclimate-temperature reconstructions from eastern Africa used to assess the relationship between these climate variables during the Holocene and the last Glacial period at the regional scale

  1. Including this study the respective temperature reconstructions30,104,105,107,110 use three different lipid biomarkers (isoprenoid GDGTs, branched GDGTs, alkenones) and five different calibrations. The paired Gulf of Aden reconstruction combines a spatially integrated view of terrestrial hydroclimate108 with local SST107. In the four studies employing δDwax as hydroclimate proxy86,104,105,108 this biomarker is considered to primarily reflect the amount of precipitation, while in other lake studies it has been interpreted to reflect past variation in moisture source131 or effective moisture132, or to contain an imprint of past changes in relative humidity133. Period covered refers to the interval of paired data in each record. Pearson’s coefficient (R) expresses linear correlation, Spearman’s rank correlation coefficient (ρ) indicates the strength of non-parametric regression, and the statistical significance of all relationships is indicated with p values. Note that more negative δDwax and δ13Cwax values reflect wetter climate conditions, hence negative R and ρ values indicate a positive relationship between hydroclimate and temperature.
