Senator McALLISTER (New South Wales—Minister for Emergency Management and Minister for Cities) (14:23): It again appears that the Greens political party are inviting us to offer and speculate about the kinds of targets we might propose prior to receiving the advice from the Climate Change Authority. It appears that what you'd prefer is a speculative process where we pick targets out of the air. What's actually being undertaken is analysis from the Climate Change Authority, which precedes government consideration of any target, which will be announced at the appropriate time. The truth is that action is required, and it's required because of the consequences for Australia and for our neighbours if we cannot, as a world, come to terms and start to reverse the warming trends that are causing so much damage to our communities. We are back at the table, part of the international community working to forge exactly such an agreement.
