Figure 1: Glacial–interglacial changes in deep-sea carbonate ion concentration. There is no shortage of alternative scenarios proposed to lower atmospheric CO 2 down to glacial values ...
Most of my work has focused on the last full glacial-interglacial cycle, spanning roughly the past 150,000 years. Major variations in ocean circulation, from the surface to abyssal depths, have ...
The most recent glacial period occurred between about 120,000 and 11,500 years ago (archived here). Since then, Earth has ...
