Exhibition Text

This graph shows 110,000 years of temperature derived from the Greenland ice core modeled here, called GISP2. For most of this time, Earth was in an ice age. Greenland climate was much colder than today, but subject to rapid climate swings. The last 100,000 years, however, have been marked by relative warmth and stability. High-resolution records from GISP2 and other ice cores enable scientists to study past climate in detail.
