Comment on "Deep-Sea Temperature and Ice Volume Changes Across the Pliocene-Pleistocene Climate Transitions"

Yu, Jimin; Broeker, Wally S.

Description

Sosdian and Rosenthal (Reports, 17 July 2009, p. 306) used magnesium/calcium ratios in benthic foraminifera from the North Atlantic to reconstruct past bottom-water temperatures. They suggested that both ice volume change and ice-sheet dynamics played important roles during the late Pliocene and mid-Pleistocene climate transitions. We present evidence that their record of deep ocean temperature is not reliable, thus raising doubts about their conclusions.
