In the series and the book, described how the "first global scientific consensus" that the world was "entering an era of unprecedented climate change" had emerged in the June 1988 international Toronto Conference on the Changing Atmosphere chaired by Stephen Lewis, and with 300 scientists from around the world in attendance. The foundation was formed in response to a 1989 meeting organized by David Suzuki and Tara Cullis with about a dozen invited guests who wanted to work towards reversing global climate change. The Foundation was incorporated on September 14, 1990. Suzuki stepped down from the Board of Directors of the Foundation in April 2012—his wife, Tara Cullis, serves as president of the Board.
