Southern Ocean biogenic blooms freezing-in Oligocene colder climates
Crossing a key atmospheric CO(2) threshold triggered a fundamental global climate reorganisation ~34 million years ago (Ma) establishing permanent Antarctic ice sheets. Curiously, a more dramatic CO(2) decline (~800–400 ppm by the Early Oligocene(~27 Ma)), postdates initial ice sheet expansion but t...
