Alaska is warming up. It's now a few degrees warmer than it was a century and a half ago, and the trend seems to be accelerating. Already the landscape is changing dramatically -- permafrost is thawing, glaciers are melting, forests are succumbing to drought and insect attack. Alan Alda meets Alaskan scientists who are working to find out if these are the first signs of global warming and what the future may hold.

AV Benefits:

Why the AV version? Because it provides additional usage options for PBS videos. AV versions come with limited performance rights so they can be shown in classrooms, at PTA meetings, during after school programs, and transmitted on a closed-circuit system within a building or on a single campus. They also can be enjoyed in admission-free public screenings, which also makes them ideal for use by library patrons and businesses involved in community clubs and organizations.
