Known for his numerous polar expeditions, deep understanding of the environment and his efforts to raise international awareness, Will has been an eyewitness to the on-going catastrophic consequences of global warming. He has traveled tens of thousands of miles by kayak and dogsled over 40 years, leading teams on some of the most significant polar expeditions in history. He led the first confirmed dogsled journey to the North Pole without re-supply, a traverse of Greenland that was the longest unsupported dogsled expedition in history, the first dogsled traverse of Antarctica, and the first dogsled traverse of the Arctic Ocean from Russia to Ellesmere Island in Canada. Over 20 million students followed the 1995 International Arctic Project via on-line daily journal entries and the first-ever transmission of a digital photograph from the North Pole. In 1996, Will became the National Geographic Society’s first Explorer-in-Residence. He is the author of four books: "Over the Top of the World," "Crossing Antarctica," "North to the Pole" and "Saving the Earth."
