Abstract

Extensive records exist with which to assess the relationship between external climate forcings — such as changes in insolation — and climate variability for middle and high latitudes, but records from equatorial regions are relatively few, especially from regions experiencing the passage of the Intertropical Convergence Zone. A continuous and well-resolved climate-proxy record of hydrological variability during the past 25,000 years from equatorial East Africa is now presented and analysed.
