Palaeoclimatology

Abstract: It seems strange, but ice cores can be drilled in the tropics from glaciers on the top of mountains. Such cores can yield invaluable data about past climate, yet information in trapped gas bubbles will be lost if the ice warms above a certain temperature. Hence the problem of keeping the ice cold on its journey down the mountain; and hence the imaginative project, now underway, to drill a core on the glacier on a Bolivian mountain and use a hot-air balloon to fly sections of it down to freezer facilities on the plain below.
