LETTERS The new Member for Corangamite seems to have a strong orientation towards the environment. And despite a self-proclaimed fondness for water, seemingly strong disorientation when it comes to working out whether Gellibrand is in the middle reaches or the bottom of the catchment (Colac Herald, November 20). Given that the IPCC's position is that the paltry three percent of total carbon dioxide "emissions" attributable to humans is the primary cause for the warming we have seen since 1950 (but not before 1950), perhaps the member for Corangamite might like to explain to the paying public what the cause of the warming was between 1900 and 1950? Does this representative of the Australian Parliament want us to accept that although the rate of warming was the same over the entire century, that one mechanism was responsible for the first 50 years and humans somehow responsible for the second? Bernie Franke, Upper Gellibrand
