Denali National Park, Alaska

From the tundra to the glaciers to the permafrost, Alaska and the Arctic are changing with the changing climate.

Join Ira Flatow and guest in this hour of Science Friday, live from Fairbanks, Alaska, for a look at how climate change is re-shaping our northernmost state. How will a change in temperature affect the plants and animals that make their homes here?

Plus, the leader of a recent 2,000 mile-plus expedition across the changing Arctic joins us to talk about the trip. Call in with your questions and comments at 1-800-989-8255 (2-3 Eastern). Teachers, find more information about using Science Friday as a classroom resource in the Kids' Connection.
