On glacia-interglacial timescales, the CO2 concentration in the atmosphere has varied between 180 and 280 parts per million (ppm), with lower values during glacial periods. Since the first measurement of ice age CO2 concentration four decades ago, much efforts have been devoted to understand why CO2 was lower during ice ages. One of the leading hypotheses pointed to changes in the Southern Ocean. A new article coauthored by Prof. Xingchen (Tony) Wang reviewed the role of the Southern Ocean in driving glacial/interglacial atmospheric CO2 changes. This article, entitled "The Southern Ocean during the ice ages: A review of the Antarctic surface isolation hypothesis, with comparison to the North Pacific", was published in Quaternary Science Reviews. For more information, please visit Prof. Wang's website.
