In a commentary published alongside the study, Andrea Dutton, a professor in the department of geoscience at the University of Wisconsin-Madison, and Robert M.
DeConto, a professor at the School of Earth and Sustainability at the University of Massachusetts Amherst, called the new research “pioneering.”
They noted that while geological evidence had been mounting that the icy expanse of the West Antarctic ice sheet may have collapsed during the Last Interglacial period, “each study’s findings have come with caveats.”
