Antarctic ice sheet is result of CO2 decrease, not continental breakup
July 30, 2014
Climate modelers at the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide (CO2) levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic Ice Sheet.
