Climate change presents a new kind of challenge. It is uncertain in its form and extent, rather than drawn in clear lines. It is insidious, rather than directly confrontational. It is long term, rather than immediate in both its impacts and its remedies. Remedies will require global co-operation of unprecedented complexity and dimension. We have much to contribute and much to lose as we face the diabolical policy challenge of climate change. (Professor Ross Garnaut)
