A record of climate change frozen in ice

  • Exhibition Text

    • Atop the Greenland Ice Cap, glaciologists have drilled through 3,000 meters of accumulated ice, all the way to bedrock. The ice cores they extracted contain a detailed climate record, extending back 115,000 years, that built up slowly from annual layers of snowfall. The layers in the ice tell of dramatic and extremely rapid climate fluctuations — significantly greater than those during the stable period of the last 10,000 years. The rapid fluctuations and prolonged stable periods are among the mysteries that climate scientists seek to solve.
