Description
The authors analyzed % biogenic silica (%BSi) from piston cores retrieved from Lake Edward (0°N, 30°E), Uganda Congo, equatorial East Africa. Correlation of %BSi with other climatologically-forced geochemical and lake level records from other equatorial African lakes further allowed them to develop a regional precipitation and drought history over the past 5400 years. Results indicated that drought affected "virtually all of tropical East Africa" between ~AD 1000 and 1200, which falls well within the era of the Medieval Warm Period.
