Polar perspective of late-Quaternary climates in the southern hemisphere

Auteur :
HEUSSER, C. J.

Description :
Late-Quaternary paleoecological and glacial evidence from the higher latitudes of the Southern Hemisphere implies overall uniformity of large-scale glacial and interglacial climatic fluctuations for the past 40 000 yr. Climate of the last glacial maximum, dated between 30 000 and 11 000 B.P., was relatively cold and dry compared with the warmer, more humid climate of the Holocene and the interstade preceding the last glacial maximum. General atmospheric circulation models for the polar latitudes at the time of the last glacial maximum show an intensification of the southern westerlies, apparently a result of the expansion of ice cover in Antarctica.
