Six years in the making, the documentary follows 40 scientists at work in the Arctic, Antarctic, Southern Ocean, New Zealand, Europe and the United States (including Purdue’s Matthew Huber).  The film is a joint initiative between Oxford University, United Kingdom, Victoria University of Wellington, New Zealand (VUW), and London-based DOX Productions. In this documentary, Prof. Simon Lamb seeks to give the audience the chance to find out just what scientists working in this field are doing, and why their findings cause them so much concern. Excerpts from the 73-minute film are now available, and the full feature willbe available online at no charge for two days from the beginning of Earth Day in New Zealand (midnight 22 April, 2013) at THIN ICE.
