Will Steger, Will Steger foundation

This is a video that documents the reflections of members of the Steger International Polar Expedition team reunited at the 25th anniversary of their landmark trek to the Arctic, and how climate change has made their trek difficult to replicate.

Video length: 14 minutes.

Climate Literacy
About Teaching Climate Literacy

The interconnectedness of Earth’s systems means that a significant change in any one component of the climate system can influence the equilibrium of the entire Earth system. Positive feedback loops can amplify these effects and trigger abrupt changes in the climate system. These complex interactions may result in climate change that is more rapid and on a larger scale than projected by current climate models.
About Teaching Principle 2
Other materials addressing 2f
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.
About Teaching Principle 5
Other materials addressing 5b
Scientists and economists predict that there will be both positive and negative impacts from global climate change. If warming exceeds 2 to 3°C (3.6 to 5.4°F) over the next century, the consequences of the negative impacts are likely to be much greater than the consequences of the positive impacts.
About Teaching Principle 6
Other materials addressing 6e
Ecosystems on land and in the ocean have been and will continue to be disturbed by climate change. Animals, plants, bacteria, and viruses will migrate to new areas with favorable climate conditions. Infectious diseases and certain species will be able to invade areas that they did not previously inhabit.

Teaching Tips

  • Useful when teaching about observed changes in the Arctic. Snippets of this series of voices on the video could be used for a personal perspective to either introduce or conclude climate lessons.

About the Science

  • This video features members of the 1986 Steger International Polar expedition speaking of their experiences and observations since that time. They discuss how sea ice cover has changed, the impacts on wildlife, the temperature of air and water in the Arctic, and the ripple effects that can be noted around the world.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • The video itself is not accompanied by any teacher support materials but the website has many associated resources available.

Technical Details/Ease of Use

  • Good quality video and audio. Editing is effective but somewhat distracting.
