Abrupt climatic changes; the Antarctic ice record during the Late Pleistocene

Abstract

At the decade to century time-scale there is no firm conclusion about the presence of rapid climatic changes since seasonal oscillation is not completely averaged out. At the century to millennium time-scale there are characteristic features of rapid warmings and coolings during the Last Glacial Maximum with a rate of temperature change of about 3 degrees C/ka. This rate is similar to the one observed during the last deglaciation. -from Authors
