Two views of the summit of ice field atop Tanzania's Mount Kilimanjaro, site of an Ohio State University expedition that has shown that global warming is slowly, but surely melting Africa's only ice cap. Above and at the base of the wall at the bottom of the image, the researchers' base camp can be seen. Below, a similar view, days later shows the expedition's drill site atop the ice field. The drill, protected by a geodesic dome, yielded records dating back 11,700 years.
Above, late in the afternoon at the drill site atop Tanzania's Mount Kilimanjaro, researchers continued to drill one of the six cores they retrieved from the mountaintop. An analysis of the climate records trapped in the cores show at least three catastrophic drought events that struck the region centuries ago. Below, what remains of one of the small glaciers still lingering atop the mountain.
Below, a large flake of ice stands solemnly, the last vestige of a blanket of ice that covered the peak. The large remaining ice field seen in the distance may have disappeared within the next 15 years, according to Ohio State University researchers.
