Rapid thinning of Pine Island Glacier in the early Holocene
Pine Island Glacier, a major outlet of the West Antarctic Ice Sheet, has been undergoing rapid thinning and retreat for the past two decades. Here we demonstrate, using glacial-geological and geochronological data, that Pine Island Glacier also experienced rapid thinning during the early Holocene, a...
