The ACTING DEPUTY PRESIDENT ( Senator Lines ) (17:31): A letter has been received from Senator Milne : Pursuant to standing order 75, I propose that the following matter of public importance be submitted to the Senate for discussion: "The embarrassment caused to Australia on the global stage resulting from the Prime Minister Abbott's climate denial and refusal to commit funds to the UN Green Climate Fund, to assist poor nations combat climate change." Is the proposal supported? More than the number of senators required by the standing orders having risen in their places— The ACTING DEPUTY PRESIDENT: I understand that informal arrangements have been made to allocate specific times to each of the speakers in today’s debate. With the concurrence of the Senate, I shall ask the clerks to set the clock accordingly.
