Relationship between Antarctic sea ice and southwest African climate during the late Quaternary
International audience Here we compare late Quaternary southwest African climate records from the west coast of southern Africa (published winter rainfall and trade wind intensity records from a core off the coast of Namibia) to records of Antarctic sea-ice extent. This comparison reveals coherent c...
