Sea ice is one of many indicators scientists use to monitor the condition of our planet. Learn about what scientists are discovering about sea ice, and the larger story the data may be telling.
- The visualization shows the thawing and freezing of sea ice from 1993 to the present. Do you notice any significant changes in the pattern of freezing and thawing over the 10-year period?
- What does the visualization say about the pattern of freezing and thawing over the last three decades?
- The science behind global warming is very complex and highly debated in the scientific community. How does the data about the thawing and freezing of sea ice in the Arctic support the global warming theory? (For more information about global warming, go to: What Causes Climate and Climate Change? Ice Ages, http://learn.amnh.org/courses/earth/documents/W4El_iceages.html.)
- How does the positive feedback loop cycle created by dwindling sea ice contribute to the warming trend in the Arctic?
