How many more reports are needed before it is accepted unequivocably that climate change as a result of greenhouse gas emissions is upon us? Apparently at least one more, as a major Australian report has been released. This and previous reports have indicated the potentially cataclysmic impacts upon arid Australia - perhaps making large swathes of the country uninhabitable (even more than currently). It is time for Australians to get their heads out of their pints of beer and realize that continental level ecological sustainability is a stake. As a start, they should ratify Kyoto immediately.
