Perspectives

Wallace Broecker

During glacial cycles, different parts of the Earth cool by different amounts. A growing collection of evidence has begun to show that cooling in the tropical oceans was greater than previously thought. In his Perspective, Broecker discusses the oxygen isotope evidence reported by Schrag et al. (p. 1930) that indicates that the cooling in deep tropical water was close to the freezing point.
