Gary Warden was raised in the Perth Hills. After graduating from the University of Western Australia with a degree in Geology, Gary joined BHP Billiton where he spent 18 years working in a variety of roles in a number of locations around the world. Prior to leaving BHP Billiton in December 2006, Gary was Global Manager for the company's US$1Billion business improvement program.
While he was originally sceptical about the claims relating to climate change, he became convinced of the urgency of the issue in early 2006. He left BHP Billiton primarily to spend more time with his young family, but also to dedicate himself to helping to ward off climate change.
In September 2007 he was trained by Al Gore and has delivered the "Inconvenient Truth" lectures to thousands of west australians since then. In November 2007 Gary ran for the senate in the Federal Election representing the Climate Change Coalition.
In addition to his climate change lectures, he facilitates Living Smart workshops across Perth. In September 2008 he was elected to the Executive Committee of the Conservation Council of WA and he is also Executive Director of the very exciting Days of Change program that aims to engage 200,000 West Australians to take simple steps to reduce their greenhouse gas emissions during March 2010.
