Correction to: Communications Earth & Environment https://doi.org/10.1038/s43247-021-00339-9, published online 13 January 2022. The original version of this Article contained an error in the second sentence of the caption of Figure 4 which incorrectly read ‘Change-points in (c) are based on changes in the mean (red) and standard deviation (blue) of the Ti/Al time-series (closed triangles) and Ti/Al residuals (open triangles) after removing low-frequency (140–1200 kyr) variability; f pollen zones from ODP Site 659 ref. 32 (green = more humid; yellow/orange = increasing aridity and humid/arid variability); g, h aeolian dust records from offshore West Africa24, 25, i ODP Site 959 Ti/Al (grey)28 with 11-point running average (red); j tree index based on pollen from Baringo Basin core BTB13, with 95% confidence intervals37 (downward bars limited to the y-axis); k DSDP Site 231 leaf wax δD with inferred shift to more aridity at 3.3–3.0 Ma ref. 38, l ODP Site 1165 ice-rafted debris (IRD) fluxes51, m global sea-level reconstruction79 based on benthic δ18O (ref. 69)’. The correct version states ‘j tree index based on phytoliths’ in place of ‘j tree index based on pollen’. This has been corrected in both the PDF and HTML versions of the Article
