Climate change and Kilimanjaro
Global warming and Kilimanjaro: where have Kilimanjaro’s glaciers gone?
Of the 19 square kilometres of glacial ice to be found on Africa, only 2.2 square kilometres can be found on Kilimanjaro. Unfortunately, both figures used to be much higher:
Kili’s famous glaciers have shrunk by a whopping 82% since the first survey of the
summit in 1912. Even since 1989, when there were 3.3 square kilometres, there has
been a decline of 33%. At that rate, say the experts, Kili will be completely ice-
Should we be worried about Kilimanjaro’s disappearing glaciers?
The big question, therefore, is not whether Kilimanjaro’s glaciers are shrinking, but why – and should we be concerned? Certainly glacial retreats are nothing new: Hans Meyer, the first man to conquer Kilimanjaro, returned in 1898, nine years after his ascent, and was horrified by the extent to which the glaciers had shrunk. The ice on Kibo’s slopes had retreated by 100m on all sides, while one of the notches he had used to gain access to the crater in 1889 – and now called the Hans Meyer Notch – was twice as wide, with the ice only half as thick.
Nor are warnings of the complete disappearance of the glaciers anything new: in 1899 Meyer himself predicted that they would be gone within three decades, and the top of Kili would be decorated with nothing but bare rock.
What concerns today’s scientists, however, is that this current reduction in size
of Kili’s ice-
Scientific studies of Kilimanjaro’s disappearing glaciers
Professor Thompson and his team are attempting to find answers to all these questions.
In January and February 2000 they drilled six ice cores through three of Kibo’s glaciers
in order to research the history of the mountain’s climate over the centuries. (Follow
this link to read a BBC report of their work). A weather station was also placed
on the Northern Icefield to see how the current climate affects the build-
Although results are still coming in from Professor Thompson’s work, early indications
were not good. In a speech made at the annual meeting of the American Association
for the Advancement of Science in February 2001, the professor declared that, while
he cannot be sure why the ice is melting away so quickly, what is certain is that
if the glaciers continue to shrink at current rates, the summit could be completely
ice-
What the future holds for Kilimanjaro’s glaciers
Whatever the reasons, if Kilimanjaro is to lose its snowy top, the repercussions
would be extremely serious: Kilimanjaro’s glaciers are essential to the survival
of the local villages, supplying their drinking water, the water to irrigate their
crops and, through hydroelectric production, their power; never mind the blow the
loss of the snow-
And these are just the local consequences. If the scientists are to be believed,
what is happening on Kilimanjaro is a microcosm of what could face the entire world
in future. Even more worryingly, more and more scientists are now starting to think
that this future is probably already upon us.
