#Alaska: Ancient cave sediments provide new #climate clues

EurekAlert!Alaska: Ancient cave sediments provide new climate cluesPaul Wilcox, a geologist at the University of Innsbruck, has discovered the first land-based evidence of meltwater pulses from the Cordilleran Ice Sheet during the last ice age about 20,000 years ago. The age of the cave sediments was constrained via optical dating techniques, which is crucial to help piece together the sequence of climate events leading to a warming planet. The results were published in the journal Nature Geoscience.
