The sun never sets, the air is twenty degrees below zero, and the ice is moving at four hundred yards an hour. Welcome to the North Pole. In 2003, environmental reporter Andrew Revkin joined a scientific expedition to one of the world's last uncharted frontiers, where he was the first New York Times reporter ever to file stories and photographs from the top of the world.<br><br>In his quest to understand the pole, Andrew leads readers through the mysterious history of arctic exploration; he follows oceanographers as they drill a hole through nine feet of ice to dive into waters below; peers into the mysteries of climate modeling and global warming; and ultimately shows how the fate of the pole will affect us all.
