THE snows of Kilimanjaro may soon be gone.
The African mountain's white peak - made famous by writer Ernest Hemingway - is rapidly melting, researchers report.
Some 85 percent of the ice that made up the mountaintop glaciers in 1912 was gone by 2007, researchers led by paleoclimatologist Lonnie Thompson of Ohio State University reported in yesterday's edition of Proceedings of the National Academy of Sciences.
And more than a quarter of the ice present in 2000 was gone by 2007.
If current conditions continue "the ice fields atop Kilimanjaro will not endure," the researchers said.
The Kilimanjaro glaciers are both shrinking, as the ice at their edges melts, and thinning, the researchers found.
Similar changes are being reported at Mount Kenya and the Rwenzori Mountains in Africa and at glaciers in South America and the Himalayas.
"The fact that so many glaciers throughout the tropics and sub-tropics are showing similar responses suggests an underlying common cause," Thompson said.
"The increase of Earth's near surface temperatures, coupled with even greater increases in the mid- to upper-tropical troposphere, as documented in recent decades, would at least partially explain" the observations.
Changes in cloudiness and snowfall may also be involved, though they appear less important, the study said.
