Researchers investigate changes in atmospheric CO₂ levels between glacial and interglacial climates

Paleoclimate scientists are trying to understand the causes of the ~90 parts per million (ppmv) atmospheric CO2 swings between glacial and interglacial climates. Even though these cycles between cold and warm periods seem to follow a pattern, researchers believe many different natural processes are involved in causing the CO2 changes.
