The UH Manoa Distinguished Lecture Series features noted American environmentalist and writer Bill McKibben in two lectures on April 15.

McKibben frequently writes about global warming, alternative energy, and the risks associated with human genetic engineering. Beginning in the summer of 2006, he led the organization of the largest demonstrations against global warming in American history.

His appearances include a seminar, "Building an International Climate Movement," at 3 p.m., in the Architecture Auditorium, and "Deep Economy: What the World Looks Like When We Take the Environment Seriously," at 7 p.m. in the Campus Center Ballroom.

Sponsors of McKibben's appearance said his first book, "The End of Nature," published in 1989 is regarded as the first book for a general audience about climate change, and has been printed in more than 20 languages.

His next book, "The Age of Missing Information," was published in 1992. It is an account of an experiment. McKibben collected everything that came across the 100 channels of cable TV on the Fairfax, Virginia system (at the time among the nation's largest) for a single day. He spent a year watching the 2,400 hours of videotape, and then compared it to a day spent on the mountaintop near his home. This book has been widely used in colleges and high schools, and was reissued in a new edition in 2006.

His Manoa appearances are cosponsored by the Environmental Center, UH Manoa. For more information about the Distinguished Lecture Series: http://manoa.hawaii.edu/dls/ <http://manoa.hawaii.edu/dls/>
