Turnbull ridicules climate sceptics - presumably including those in his own party

If only this bloke was Opposition Leader, you could head into the next election without quite so much concern for the country.

Malcolm Turnbull has piled the scorn on (in the way he does so well) onto climate change sceptics. So Barnaby Joyce - that's you he's talking about.

He points out that even when big deniers in the US financed a study to try to disprove it, even that study came up ratifying the IPCC.

Meanwhile, the commentators continue to start lining up their concerns about the unsustainability of Tony Abbott in leadership, with this piece from The Australian's Troy Bramston:

They will ask voters to "take another look" at the government and "a long hard look" at the opposition. When voters do, they'll find an opposition not ready to govern.
