During interglacial periods - we are enjoying one now, East Coast blizzards notwithstanding - the ice sheets retreat, the glaciers melt and sea level rises. The expansive but quickly melting ice sheets of Greenland, the North Pole and Antarctica are all that is left of our last glacial period, which reached its peak about 20,000 years...

"But as a paleontologist, I live my life looking down at the ground," says Saint Onge, who runs an archaeological-consulting firm out of nearby...
