GUNUNG KILIMANJARO
Kilimanjaro, with its three volcanic
cones, Kibo, Mawenzi, and Shira, is a dormant volcano in Kilimanjaro National
Park, Tanzania and the highest mountain in Africa at 5,895 metres or 19,341
feet above sea level (the Uhuru Peak/Kibo Peak).
In the late 1880s the summit of Kibo was completely covered by an ice cap with
outlet glaciers cascading down the western and southern slopes, and, except for
the inner cone, the entire caldera was buried. Glacier ice flowed also through
the Western Breach.
An examination of ice cores taken from the North Ice Field Glacier indicate
that the "snows of Kilimanjaro" (aka glaciers) have a basal age of
11,700 years. A continuous ice cap covering approximately 400 square kilometers
covered the mountain during the period of maximum glaciation, extending across
the summits of Kibo and Mawenzi. The glacial ice survived drought conditions
during a three century period beginning ~2200 BCE.The period from 1912 to present has witnessed the disappearance of more than 80% of the ice cover on Kilimanjaro. From 1912-1953 there was ~1% annual loss, while 1989-2007 saw ~2.5% annual loss. Of the ice cover still present in 2000, 26% had disappeared by 2007. While the current shrinking and thinning of Kilimanjaro's ice fields appears to be unique within its almost twelve millennium history, it is contemporaneous with widespread glacier retreat in mid-to-low latitudes across the globe. At the current rate, Kilimanjaro is expected to become ice-free some time between 2022 and 2033.
