Arctic expedition records signs of global warming
Today is Earth Day. Minnesotan and polar explorer Will Steger will spend the day on Ellesmere Island in the Canadian Arctic. Steger is leading a 1400-mile dogsled expedition across the island; he hopes to record the impact of global warming on the northernmost part of the North American continent. Morning Edition host Cathy Wurzer talked with Steger by satellite phone.
