Gary Braasch's photographic work centers on environmental issues and conservation, biodiversity, ecosystems, field science and climate change. One of the environments at the heart of his conservation work is the Alaskan tundra, and he has one of the few comprehensive photo documentations of this huge and wild area. It has been a rewarding couple of years for Gary: In September, the Sierra Club presented him the 2006 Ansel Adams Award for Conservation Photography; his book, "Earth Under Fire: How Global Warming Is Changing the World," will be published this fall by University of California Press; and the United Nations has chosen him to illustrate its 2007 calendar, which will feature the work of the international climate change, biodiversity and desertification treaties.
