Ice sheets

Being buried by [ice:mice] would seem like a death sentence. But some moss recently freed from the deep freeze after four [centuries:entries] appears to be doing just fine. That's according to a [report:discourse] in the Proceedings of the National Academy of Sciences. Ice sheets the world over are melting back and that's particularly true in the Arctic. The meltdown is picking up pace, too. As the ice [retreats:deflects] it uncovers the foliage it had entombed. Researchers gathered a sample of such flora in the Canadian [territory:factory] of Nunavut to gauge its condition. Carbon dating showed that the vegetation had not seen the [sun:ray] since at least near the start of the Little Ice Age, some 400 years ago.
