Vostok ice core provides 160,000-year record of atmospheric CO2
Abstract
Direct evidence of past atmospheric CO2 changes has been extended to the past 160,000 years from the Vostok ice core. These changes are most notably an inherent phenomenon of change between glacial and interglacial periods. Besides this major 100,000-year cycle, the CO2 record seems to exhibit a cyclic change with a period of some 21,000 years.
