Scientists discover ancient seawater preserved from the last Ice Age

Twenty thousand years ago, in the thick of an Ice Age, Earth looked very different. Because water was locked up in glaciers hundreds of feet thick, which stretched down over Chicago and New York City, the ocean was smaller—shorelines extended hundreds of miles farther out, and the remaining water was saltier and colder. Assistant Professor Clara Blattler with a vial of seawater dating to the last Ice Age — about 20,000 years ago...
