When glaciologist Lonnie Thompson returns to Peru's Qori Kalis glacier early this summer, he expects to find that half of the ice he saw during his visit there last year has vanished. What troubles him the most is his recent observations that suggest that the entire glacier may likely be gone within the next five years, providing possibly the clearest evidence so far of global climate change. The fact that the Qori Kalis glacier, high in the Andes Mountains , is only one of many ice tongues retreating on the Quelccaya Ice Cap, the largest body of ice in the tropics, provides strong evidence of the warming that appears to be underway worldwide. Thompson, Distinguished University Professor in the School of Earth Sciences at Ohio State University and a world-acclaimed paleoclimatologist, outlined his fears at the annual meeting of the American Association for the Advancement of Science in San Francisco this week.
