While a shadow minister, Tony Abbott was never afraid of speaking bluntly in a manner that was at odds with Coalition policy.
So as I am a humble backbencher I am sure he won't complain if I tell a few home truths about the farce that the Coalition's policy, or lack of policy, on climate change has descended into.
First, let's get this straight. You cannot cut emissions without a cost. To replace dirty coal fired power stations with cleaner gas fired ones, or renewables like wind let alone nuclear power or even coal fired power with carbon capture and storage is all going to cost money.
To get farmers to change the way they manage their land, or plant trees and vegetation all costs money.
Somebody has to pay.
So any suggestion that you can dramatically cut emissions without any cost is, to use a favourite term of Mr Abbott, "bullshit." Moreover he knows it.
The whole argument for an emissions trading scheme as opposed to cutting emissions via a carbon tax or simply by regulation is that it is cheaper - in other words, electricity prices will rise by less to achieve the same level of emission reductions.
The term you will see used for this is "least cost abatement".
It is not possible to criticise the new Coalition policy on climate change because it does not exist. Mr Abbott apparently knows what he is against, but not what he is for.
Second, as we are being blunt, the fact is that Tony and the people who put him in his job do not want to do anything about climate change. They do not believe in human caused global warming. As Tony observed on one occasion "climate change is crap" or if you consider his mentor, Senator Minchin, the world is not warming, it's cooling and the climate change issue is part of a vast left wing conspiracy to deindustrialise the world.
Now politics is about conviction and a commitment to carry out those convictions. The Liberal Party is currently led by people whose conviction on climate change is that it is "crap" and you don't need to do anything about it. Any policy that is announced will simply be a con, an environmental figleaf to cover a determination to do nothing. After all, as Nick Minchin observed, in his view the majority of the Party Room do not believe in human caused global warming at all. I disagree with that assessment, but many people in the community will be excused for thinking the leadership ballot proved him right.
Remember Nick Minchin's defense of the Howard Government's ETS was that the Government was panicked by the polls and therefore didn't really mean it.
Tony himself has, in just four or five months, publicly advocated the blocking of the ETS, the passing of the ETS, the amending of the ETS and, if the amendments were satisfactory, passing it, and now the blocking of it.
His only redeeming virtue in this remarkable lack of conviction is that every time he announced a new position to me he would preface it with "Mate, mate, I know I am a bit of a weather vane on this, but....."
Third, there is a major issue of integrity at stake here and Liberals should reflect very deeply on it. We have an Opposition whose current leadership dismisses the Howard Government's ETS policy as being just a political ploy. We have an Opposition Leader who has in the space of a few months held every possible position on the issue, each one contradicting the position he expressed earlier. And finally we have an Opposition which negotiated amendments to the Rudd Government's ETS, then reached agreement on those amendments and then, a week later, reneged on the agreement.
Many Liberals are rightly dismayed that on this vital issue of climate change we are not simply without a policy, without any prospect of having a credible policy but we are now without integrity. We have given our opponents the irrefutable, undeniable evidence that we cannot be trusted.
Not that anyone would doubt it, but I will be voting for the ETS legislation when it returns in February and if my colleagues have any sense they will do so as well.
