Psst...it's all about climate change

It was a bit frustrating listening to Fran Kelly interview a couple of Liberals this morning about their leadership crisis and not have her or her guests get to the crux of the divide between the conservative and moderate split within the party.

It's obvious:  it is climate change.   The so-called conservatives in the party deny reality on this,   commentators should be not shy about calling this out as being at the heart of the Liberal crisis.

Update:  yes, Graham Readfearn said the same thing yesterday: 

Climate change denial is at the root of the half-baked policies and outright wrecking that have blighted the past decade

Why aren't more commentators saying it?

And why isn't there anyone calling for an outright split in the Liberals over it?
