Based on field surveys and analyses of optical spaceborne images (LandSat5, LandSat7), we report recent decline in the areal extent of glaciers in the Rwenzori Mountains of East Africa from 2.01 ± 0.56 km2 in 1987 to 0.96 ± 0.34 km2 in 2003. The spatially uniform loss of glacial cover at lower elevations together with meteorological trends derived from both station and reanalysis data, indicate that increased air temperature is the main driver. Clear trends toward increased air temperatures…

Expanded glaciers during a dry and cold Last Glacial Maximum in equatorial East Africa

Glaciers on the world's highest tropical mountains are among the most sensitive components of the cryosphere, yet the climatic controls that infl uence their fl uctuations are not fully under- stood.

[1] The focal point – and new contribution to the community – of the study by Taylor et al. [2006] is the derivation of recent (1987, 1995, 2003) glacial extent in the central Rwenzori Mountains,

Climatic forcing of glacier thinning on the mountains of equatorial East Africa

Equatorial glaciers are particularly climate sensitive components of the environment and their area shrinkage is spectacular, but the quantitative appraisal of climatic forcing requires information

Nonuniform Late Pleistocene glacier fluctuations in tropical Eastern Africa

A chronological comparison for the Ethiopian Highlands in comparison with other East African Mountains reveals that glaciers in Eastern Africa responded in a nonuniform way to past climatic changes, indicating a regionally varying influence of precipitation, temperature, and orography on paleoglacier dynamics.
