Drilling Back to the Future: Climate Clues from Ancient Ice on Greenland
https://vimeo.com/6971081

Climate Central

This video, from ClimateCentral, features a team of scientists from the Northern Greenland Eemian Ice Drilling Project (NEEM), who study atmospheric air bubbles trapped in an ice core from 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 - all aligned on the same time scale - reveal what happened with climate change over that period of time.

Video length 6:15 min.

About Teaching Climate Literacy

Scientific observations indicate that global climate has changed in the past, is changing now, and will change in the future. The magnitude and direction of this change is not the same at all locations on Earth.
About Teaching Principle 4
Other materials addressing 4d
Based on evidence from tree rings, other natural records, and scientific observations made around the world, Earth’s average temperature is now warmer than it has been for at least the past 1,300 years. Average temperatures have increased markedly in the past 50 years, especially in the North Polar Region.
About Teaching Principle 4
Other materials addressing 4e
Environmental observations are the foundation for understanding the climate system. From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.

Scientific investigations usually involve the collection of relevant data, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected data.

The earth's climates have changed in the past, are currently changing, and are expected to change in the future, primarily due to changes in the amount of light reaching places on the earth and the composition of the atmosphere. The burning of fossil fuels in the last century has increased the amount of greenhouse gases in the atmosphere, which has contributed to Earth's warming.

Teaching Tips

About the Science

  • This detailed video describes the NEEM ice core research project, which explores samples from ice cores from the Eemian period – a geological period that began about 130,000 years ago, and is potentially similar to 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.

About the Pedagogy

  • The web page associated with the video contains important background material.
  • Ties in National Guard air pilots - can be used to demonstrate that careers other than scientists can have an impact on science.

Technical Details/Ease of Use

  • High Definition can be shown on a large screen, individual computers, or at home clearly.
  • Great visuals and related resources provided can be tied in.
