Questions for Discussion: Climate Change Impacts Alaska Glaciers
- Describe how a glacier advances and retreats. How can monitoring glacial movement help scientists understand about climate change?
- In this video, how do the scientists and students measure changes in the glaciers?
- The amount of ice covering Alaska has varied greatly during the last several thousand years. Could the disappearance of tidewater glaciers be part of the regular glacial ebb and flow, or is there reason to think something different is occurring?
- How do you think melting glaciers might affect water levels in the world's oceans?
