Here are two statistics to ponder as we prepare to head to the polls this weekend: voter support for action on climate change has surged to historically high levels since the last election and; four fifths of us believe neither of the major parties actually gives a toss.

Polling released by the Climate Institute last week reveals that 72 per cent of us are worried about global warming, and that while only 17 per cent think the Coalition's climate policies are credible, the plausibility of Labor's response is ahead by just a whisker, at a paltry 20 per cent.

And, really, is it any wonder? While the Coalition and the ALP have emission-reduction targets – neither of which, it must be said, will avoid dangerous global warming – the policy detail underpinning them is woefully inadequate. It's like trying to build the Eiffel Tower with a box of matchsticks.

After a decade of flip-flopping on climate policy, the electorate, it seems, has wised up. We're not buying Labor's pledge of an "orderly" closure of coal-fired power stations – remember how well that went last time? – any more than Environment Minister Greg Hunt's enthusiasm for the Coalition's Emissions Reduction Fund which, as everyone knows, is about as effective as an ashtray on a motorbike.
