Presenters : Nick Minchin & Anna Rose. What better way to open up the discussion about climate change than to send two Australians, with opposing views, on a mutual journey of discovery around the globe. Each has the chance to track down whomever they like to help aid their side of the ongoing climate change debate. Anna Rose, co-founder of the Australian Youth Climate Coalition and Nick Minchin, former Liberal senator and climate change challenger, set out a 65,000km trip, surprising each other with the viewpoints of a range of experts, scientists, journalists, politicians and bloggers. From the farmlands of Moree, New South Wales to the lofty, volcanic heights of Hawaii to the lawns of the White House and Britain's Houses of Parliament, this program is an experiment about an issue on which Australians have never been more divided. 1.Climate change - Economic aspects ; 2.
