Six ice cores from Kilimanjaro provide an ∼11.7-thousand-year record of Holocene climate and environmental variability for eastern equatorial Africa, including three periods of abrupt climate change: ∼8.3, ∼5.2, and ∼4 thousand years ago (ka). The latter is coincident with the “First Dark Age,” the period of the greatest historically recorded drought in tropical Africa. Variable deposition of F– and Na+during the African Humid Period suggests rapidly fluctuating lake levels between ∼11.7 and 4…

Late Holocene precipitation variability in the summer rainfall region of South Africa
Abstract The late Holocene history of the South African summer rainfall zone offers insights into the effects of climate on ecosystems and human societies, as well as into the accuracy of model
Little Ice Age drought in equatorial Africa: Intertropical Convergence Zone migrations and El Niño–Southern Oscillation variability
High-resolution analyses of the Mg concentration in authigenic calcite in five cores from Lake Edward provide a water balance history of central equatorial Africa spanning the past 1400 yr. A high
Is the decline of ice on Kilimanjaro unprecedented in the Holocene?
Glaciers on Kilimanjaro’s highest peak, Kibo, are currently regarded as a persistent feature of the Holocene. Here we synthesize all available measurements, observations, and our understanding of
Tropical Glacier and Ice Core Evidence of Climate Change on Annual to Millennial Time Scales
This paper examines the potential of the stable isotopic ratios, 18O/16O (δ 18Oice)and 2H/1H (δ Dice), preserved in mid to low latitude glaciers as a toolfor paleoclimate reconstruction. Ice cores

Recently exposed vegetation reveals Holocene changes in the extent of the Quelccaya Ice Cap, Peru
Abstract Radiocarbon dating of well-preserved, in-place vegetation exposed by the retreating Quelccaya Ice Cap of southeastern Peru constrains the last time the ice cap's extent was smaller than at
Late Holocene drought responsible for the collapse of Old World civilizations is recorded in an Italian cave flowstone
A severe drought in parts of low-latitude northeastern Africa and southwestern Asia ∼4200 yr ago caused major disruption to ancient civilizations. Stable isotope, trace element, and organic

A 25,000-year tropical climate history from bolivian ice cores
TLDR
The abrupt onset and termination of a Younger Dryas-type event suggest atmospheric processes as the probable drivers of regional accumulation during the LGS, during deglaciation, and over the past 3000 years, which is concurrent with higher water levels in regional paleolakes.
Ice‐core palaeoclimate records in tropical South America since the Last Glacial Maximum
Ice-core records spanning the last 25 000 yr from the tropical Andes of South America are reviewed. These records from Quelccaya, Huascaran and Sajama present a high temporal resolution picture of
Rainfall and drought in equatorial east Africa during the past 1,100 years
TLDR
A decade-scale reconstruction of rainfall and drought in equatorial east Africa over the past 1,100 years is presented, based on lake-level and salinity fluctuations of Lake Naivasha inferred from three different palaeolimnological proxies: sediment stratigraphy and the species compositions of fossil diatom and midge assemblages.
