Drilling Back to the Future: Climate Clues from Ancient Ice on Greenland

Climate Central

This video, from ClimateCentral, features a team of scientists from the Northern Greenland Eemian Ice Drilling Project who study atmospheric air bubbles trapped in an ice core. This work highlights a period in Greenland's ice sheet which began about 130,000 years ago and lasted about 10,000 years; a period known as the Eemian. The air bubbles from the ancient atmosphere reveal what happened with climate change over that period of time.

Notes from our reviewers

The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials.

Several CLEAN resources can accompany this video to supplement it or be used to elaborate on the topic. For example, [link http://cleanet.org/resources/42848.html]
This detailed video describes how ice cores from the Eemian period illuminate what may happen to atmospheric temperatures in the next few hundred years. The video shows how scientists use a continuous sampling technique to analyze ice core samples in the field. Sophisticated correlations between increasing temperatures and levels of carbon dioxide reveal a historical record that confirms carbon dioxide is causing warming. Comments from expert scientist: The scientists interviewed are eminently experts in the field. The video does not provide references as such, but the experts giving comments are definitely of high caliber.
