Prime Minister Malcolm Turnbull made some very modest announcements at the COP21 climate change conference. He pledged Australia to the final years of the Kyoto protocol, an agreement that is about to lapse, and $800 million to developing nations for climate adaptation. This money is to come from existing foreign aid, which recent budgets have slashed. In contrast, Canada's new Prime Minister Justin Trudeau pledged $2.5 billion.
