Destination Insights  

Our show will focus on hauntingly beautiful Wrangel Island, where the last known woolly mammoths roamed, and where the first impacts of global warming can already be seen.

Tom Brokaw and a team of four world-class scientists will travel to Wrangel Island in July, 2007, aboard the icebreaker Kapitan Khlebnikov, to see the effects of global warming firsthand. There are a few spaces available for passengers who want to participate in this historic adventure.

Two of the study leaders, Dr. Ross MacPhee of the American Museum of Natural History, and Dr. John Harte of the University of California, Berkeley, will be available on the show to answer your questions about global warming, Wrangel Island, the extinction of woolly mammoths, and the future of humankind. You'll also find out how you can participate in the upcoming Symposium on Global Warming and Climate Change.

Call in to 1 (646) 652-2542 on Tuesday, February 27, 2007, at 7 p.m. Eastern time or 4 p.m. Pacific time to find out:

• Why should we believe the studies that predict global warming?
• What's the worst that could happen, and how soon?
• Did climate change cause the extinction of woolly mammoths?
• What's happening right now on Wrangel Island?
  

We've finally admitted it's happening, but what does that mean?

What is the likely impact of global warming? To what extent have humans caused it, and what can we do to reverse it? We'll explore these questions with:

- The American Museum of Natural History's Dr. Ross MacPhee, who has studied wooly mammoth remains on Wrangel Island to learn about their extinction, and

- The University of California's Dr. John Harte, whose research focuses on the effects of human actions on biodiversity, climate, and ecosystems.

You'll also learn about a voyage you can take to Wrangel Island in July, 2007, along with these scientists, to learn firsthand about the effects of global warming.
