Abstract:

Mick Sternberg had literally made the same measurement a thousand times before. But this meter-long ice core was perhaps just a little more special. He double-checked his numbers on the final length, stood back, and rechecked again.

"No reason to rush through this," he said under his breath, which steamed out in the freezing temperatures of the National Ice Core Laboratory's processing room.

After all, this last section of ice, drilled from near the bottom of the West Antarctic Ice Sheet (WAIS) at a depth of about 3,331 meters, had been waiting around for a while. Probably somewhere in the neighborhood of 55,000 to 60,000 years.
