Climate change: the challenge for Australia
Ross Garnaut writes: I once called climate change policy diabolical, but with a saving grace. It is diabolical because of the overlapping of four complex issues. While there is high scientific confidence that human action causes warming and that, beyond some limit, warming damages many aspects of human life, perhaps catastrophically, there is uncertainty about the precise consequences. The costs of effective action come now and the benefits much later. Avoidance of dangerous outcomes requires parallel action in all of the larger countries. And effective action is politically difficult because it confronts the interests of large corporations that are accustomed to investing heavily to bend policy to their own ends.
