I have never been so ashamed of politicians in Australia as right now when the leader of the Opposition, Malcolm Turnbull, is being defied by his party on the matter of climate change. Picture a 2-party democracy in which both parties are agreed that effective climate change is vital. We might have that, here in Australia, unlikely as it sounds, but for the irresponsible, ignorant Liberals who are using the issue for political effect. Shame, Tony and your cronies. Shame.
