Summary
Abstract: A detailed record of sea surface temperature from sediments of the Cape Basin
in the subtropical South Atlantic indicates a previously undocumented
progression of marine climate change between 41 and 18 thousand years before
the present (ky B.P.), during the last glacial period. Whereas marine records
typically indicate a long-term cooling into the Last Glacial Maximum (around
21 ky B.P.) consistent with gradually increasing global ice volume, the Cape
Basin record documents an interval of substantial temperate ocean warming from
41 to 25 ky B.P. The pattern is similar to that expected in response to
changes in insolation owing to variations in Earth's tilt.
