AFRICAN ICE CORE ANALYSIS REVEALS CATASTROPHIC DROUGHTS, SHRINKING ICE FIELDS AND CIVILIZATION SHIFTS
COLUMBUS, Ohio ? A detailed analysis of six cores retrieved from the rapidly shrinking ice fields atop Tanzania?s Mount Kilimanjaro shows that those tropical glaciers began forming about 11,700 years ago.
The cores also yielded remarkable evidence of three catastrophic droughts that plagued the tropics 8,300, 5,200 and 4,000 years ago.

One of the last remnants of Kilimanjaro's Eastern ice field is a six-meter spire that was much larger when seen on earlier expeditions. It should vanish in a few years due to global warming |
