The formation of the Antarctic ice sheet during a major climate shift 34 million years ago was the result of decreased carbon dioxide (CO2) levels, and not continental breakup like a widely held theory suggested, according to new research.

The 40-year-old "Southern Ocean gateway opening" theory indicated that massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. But now researchers from the University of New Hampshire (UNH) have provided evidence refuting this popular n...
