The Arts Festival will host a book-signing by alumnus and noted nature photographer James Balog on Apr. 25 at 7 p.m. in Devlin Hall. He will be signing copies of his book, ICE: Portraits of Vanishing Glaciers, a visual chronicle of the world’s majestic ice formations and the effects of climate change. The book is part of Balog’s multimedia project involving scientists, videographers, photographers, and a team of extreme-weather expedition specialists called Extreme Ice Survey, designed to document changes in the glacial landscape. Through EIS, images are captured in Greenland, Iceland, the Nepalese Himalaya, Alaska, the Rocky Mountains, the French and Swiss Alps, Canada, Iceland, and Bolivia. The resulting documentary, “Chasing Ice,” winner of Sundance’s Excellence in Cinematography Award for U.S. Documentary Filmmaking, will be screened after the book-signing at 8:00 p.m. in Devlin, Room 008. A discussion will follow. Sponsors: the Institute of Liberal Arts, BCEEAN, the Environmental Studies Program, the Earth and Environmental Sciences Department, EcoPledge, and the Arts Council. Free registration required.
