Mr TURNBULL (Wentworth—Prime Minister) (14:19): The honourable member's question seems to overlook a salient fact, which is that the government has today ratified the Paris Agreement—that is a fact. The significance of that and the importance of that agreement is one which I will invite the minister to now address. Mr Butler: Mr Speaker— The SPEAKER: The member for Port Adelaide will resume his seat. What has occurred is perfectly in order. There is extensive practice on it. If he wishes to argue with me, he can do so after question time. The minister has the call.
