Paleo Slide Set: The Ice Ages
Remnant of the Ice Age
From the time of Louis Agassiz to the present, scientists have sought to understand why glaciers once covered nearly one-third of earth's land surface. In the process, they have discovered much about earth's changing climate, but many questions still remain. Scientists are currently exploring some of the many climate feedback mechanisms in the search for the answers.
