GLACIOLOGY:
Ice Man: Lonnie Thompson Scales the Peaks for Science
Kevin Krajick
QUELCCAYA ICE CAP, PERU--Glaciologist Lonnie Thompson cores ice from the world's loftiest glaciers, seeking to retrieve precious records of ancient climate before they melt away. Last year Thompson--whom colleagues have called "the closest living thing to Indiana Jones"--made headlines by observing that the famous snows of Tanzania's Mount Kilimanjaro might be gone by 2015. Now he is on a mission, racing through expeditions to Asia, South America, and Alaska to retrieve endangered samples.
