"Decades of unusual warmth in regions from Peru to Alaska–a trend some think is linked to emissions from cars and industry–have shrunk or thawed many of the world's 70,000 glaciers. As the ice recedes, a treasure-trove of human and animal artifacts is emerging, extraordinarily well preserved after centuries in the deep freeze. The fabrics, wood, bone, and DNA-rich tissue found on the mucky fringes of the ice are revising scientists' understanding of our predecessors' health, habits, and technology, and the prey they pursued."

This is great news - maybe some evidence of a global catastrophe or ancient civilization will emerge?
