How many carbon policies can Labor have? Labor has over six years told us whatever it's saying on the global warming policy is true and urgent and right, even it it's the opposite of what it said the day before. It told us global warming was the great challenge of our generation, needing an emissions trading scheme: It then told us it was actually too early for an emissions trading scheme when the world wasn't on board: It then told us it wouldn't give us a carbon tax: It then told us we had to accept its carbon tax: It then told us that maybe its carbon tax should a bit high and would be cut in two years: It then told us there was no problem with the tax, and people didn't care: It now tells us the tax costs too much and will be cut by moving a year earlier to an emissions trading scheme, ahead of most of the world: And remember - this latest change is brought by Kevin Rudd, who last year thought the carbon tax was such a great move that he even kissed the woman who brought it in: Does Labor have any clue about global warming policy? Isn't it just making it up as it goes along? How much have these changes cost us in government ad campaigns, administrative expenses, tax compensation, business uncertainty, price rises ...? Now Labor faces a crater in its Budget: KEVIN Rudd will this week unveil budget savings worth "several billions" of dollars to fund an earlier shift to an emissions trading scheme as part of his effort to neutralise Tony Abbott's attack on the carbon tax. Samuel J at the Cat has questions about Labor's latest global warming policy: A carbon tax of $24.15 per tonne had no significant effect on global temperatures. What will a carbon tax of $6 per tonne achieve? Will the Government replace the revenue lost from reducing the carbon tax by increasing other taxes, borrowing more, or genuinely cutting expenditure? Will the Prime Minister GUARANTEE that the carbon tax will not increase to $20 or more per tonne over the next three years? As a floating tax, it could be at any level in 2016. If global warming is the âgreatest moral challenge of our generation" shouldn't the Prime Minister be increasing the carbon tax, not reducing it? How can we trust the Prime Minister to keep the carbon tax low? If he scrapes into power with a minority Government and the price of the Greens support is that the carbon tax must increase substantially, how can he give the electorate an ex ante guarantee that he will not deceive them once more by increasing the tax? Dennis Shanahan: The reality is that over time, not too much time, this decision (to bring forward the move to a floating price for carbon) will be seen to be hollow and yet another distraction from the policy failings in other areas from the Rudd-Gillard governments. Rudd is repudiating Gillard's carbon tax and her deal with the Greens and trying to paint the Liberal leader as a climate change "denier." But in doing so he is vindicating the opposition's campaign on cost-of-living and overreach on climate change. And bottom line: all these huge schemes and all this talk is about making zero real difference to a global warming that actually paused more than 15 years ago, in contradiction of all the main global warming models: What we are really seeing is the slow death of the global warm scare, but without the key fearmongers yet admitting they sacrificed reason to faith.
