Goodbye, Kilimanjaro
For most of us in the west, the African mountain Kilimanjaro is known for two things: its summit is the point on the planet at which one can see more surface area of Earth than from any other location (the North American champ for that is Mount Diablo, which I can see from my back window); and, although it sits close to the equator, its summit is perpetually shrouded in snow, a fact immortalized by Ernest Hemingway's 1938 short story, The Snows of Kilimanjaro.
Make that, "was perpetually shrouded."
In 2000, images from Landsat, one of the various Earth-observing satellites, took an alarming picture, showing that much of the snow and glaciation at the Kilimanjaro summit had disappeared in just ten years. The 1990 and 2000 photos are shown to the right; click them for larger versions at NASA. At the time, scientists estimated that the remainder of the ice and snow would be gone by 2015.
They now have to revise their estimates. Recent photos (small version to the left, click for larger) show that very little of the mountain's snow remains; what's left will probably be gone in a just a few more years. Before the decade is out, Kilimanjaro will lose the snow which covered it for the last 11,000 years -- the snow which fascinated travelers, inspired artists, and gave it the name "shining mountain." Global warming and deforestation are both culprits; the relative balance between the two is still subject to debate (see comments for links). We've linked to other before/after images showing the effect of climate disruption, but there's something deeply symbolic about this particular example.
The 2004 image is part of a collection called NorthSouthEastWest: A 360° View of Climate Change, given to the attendees of this week's G8 energy and environment summit. The UK, which becomes the head of the G8 this year, has already stated that it will try to make climate disruption the top agenda item for the organization. Pictures like these are useful for making visceral the often-academic discussions of carbon and timelines, and for driving home the point that global warming isn't a problem off in the future, but is happening -- and having serious consequences -- right now.
