MOTHER JONES - Last week, a much-discussed new paper in the journal Nature seemed to suggest to some that we needn't worry too much about the melting of Greenland, the mile-thick mass of ice at the top of the globe. The research found that the Greenland ice sheet seems to have survived a previous warm period in Earth's history—the Eemian period, some 126,000 years ago—without vanishing (although it did melt considerably).

But Ohio State University glaciologist Jason Box isn't buying it.
