Recent and long term variations in ice extent on Kilimanjaro are investigated in the context of 20th century climate change in East Africa. Quickbird satellite data show that the areal extent of glaciers on Kilimanjaro is 2.51 km2 in February 2003. To assess glacier retreat on Kilimanjaro two glacier systems are identified: (1) plateau (≥5700 m) and (2) slope (<5700 m). Vertical wall retreat that governs the retreat of plateau glaciers is irreversible, and changes in 20th century climate have…

A century of ice retreat on Kilimanjaro: the mapping reloaded
Abstract. A new and consistent time series of glacier retreat on Kilimanjaro over the last century has been established by re-interpreting two historical maps and processing nine satellite images,
Quantifying climate change in the tropical midtroposphere over East Africa from glacier shrinkage on Kilimanjaro.
Slope glaciers on Kilimanjaro (ca. 5000–6000 m MSL) reached their most recent maximum extent in the late nineteenth century (L19) and have receded since then. This study quantifies the climate signal
Mass balance of a slope glacier on Kilimanjaro and its sensitivity to climate
Meteorological and glaciological measurements obtained at 5873 m a.s.l. on Kersten Glacier, a slope glacier on the southern flanks of Kilimanjaro, are used to run a physically‐based mass balance
Mesoscale atmospheric circulation controls of local meteorological elevation gradients on Kersten Glacier near Kilimanjaro summit
Abstract. Elevation gradients of meteorological variables in mountains are of interest to a number of scientific disciplines and often required as parameters in modeling frameworks. Measurements of
Tropical glaciers, recorders and indicators of climate change, are disappearing globally
Abstract In this paper we review the interaction of El Niño Southern Oscillation (ENSO) variability and warming trends recorded in ice-core records from high-altitude tropical glaciers, discuss the
Assessment of Morphology Changes of the End Moraine of the Werenskiold Glacier (SW Spitsbergen) Using Active and Passive Remote Sensing Techniques
This study investigates four periods of archival aerial photogrammetry measurements performed for the end moraine of the Werenskiold Glacier and demonstrates that over a period of only 4 months, the moraine lost 200 thousand m3 of material, which is equivalent to the entire annual mass loss of the glacier.
Intraseasonal precipitation variability on Kilimanjaro and the East African region and its relationship to the large-scale circulation
SummaryAtmospheric circulation anomalies, related to snowfall events on the Tanzanian volcano Kilimanjaro, were analyzed based on hourly snowfall data from an automated weather station (AWS), global
Multivariate models for predicting glacier termini
Concerns over the rapid retreat rates of mountain glaciers have been rising as global temperatures have continued to increase. The extent of variation in the retreat of mountain glaciers can provide
Micrometeorological conditions and surface mass and energy fluxes on Lewis Glacier, Mt Kenya, in relation to other tropical glaciers
Abstract. The Lewis Glacier on Mt Kenya is one of the best-studied tropical glaciers, but full understanding of the interaction of the glacier mass balance and its climatic drivers has been hampered


Modern glacier retreat on Kilimanjaro as evidence of climate change: observations and facts
In recent years, Kilimanjaro and its vanishing glaciers have become an ‘icon’ of global warming, attracting broad interest. In this paper, a synopsis of (a) field observations made by the authors and
Solar‐radiation‐maintained glacier recession on Kilimanjaro drawn from combined ice‐radiation geometry modeling
[1] In the context of investigating modern glacier recession on Kilimanjaro, which began around 1880, this study addresses the glacier regime of the vertical ice walls that typically form the margins
Diagnosing the decaying glaciers of equatorial East Africa
A last mapping of Mount Kenya's vanishing glaciers was accomplished with a photo flight in September 2004. This invites a documentation of the variations in the course of the past more than a century

Glacier recession on Kilimanjaro, East Africa, 1912–89
Abstract The varying ice extent on the Kibo cone of Kilimanjaro, East Africa, this century was reconstructed from terrestrial-photogrammetric mappings in 1912 and 1953 and satellite images in 1976
Kilimanjaro Ice Core Records: Evidence of Holocene Climate Change in Tropical Africa
Variable deposition of F– and Na+during the African Humid Period suggests rapidly fluctuating lake levels between ∼11.7 and 4 ka, which is coincident with the “First Dark Age,” the period of the greatest historically recorded drought in tropical Africa.
Variations of East African Climate during the Past Two Centuries
The evidence on the climatic history of East Africa over the past two centuries comprises historical accounts of lake levels, observations and analyses of glacier variations, wind and current
Extracting a Climate Signal from 169 Glacier Records
I constructed a temperature history for different parts of the world from 169 glacier length records. Using a first-order theory of glacier dynamics, I related changes in glacier length to changes in
